jeff wrote:Significant glazing to happen tonight through Sunday from Midland to Waco to Dallas.

Per latest guidance showing high QPF in shallow sub-freezing surface air mass points to heavy icing. Expect freezing line to clear Waco this evening and reach N Austin early Sunday whiel progressing only slowly eastward through all of N TX into E TX and SE TX Sunday.

Accumulations in the Ice Storm Warning area could exceed 1.0 inch and may approach 1.5-2.0 inches.

Expect impossible surface travel and very poor aviation travel with de-icing possibly suspended at some terminals and airports closed all together on Sunday.

Power outages will become widespread and spread SE with time as freezing line seeps southward. Expect glazing to reach the I-10 corridor late Monday afternoon and presist through Wednesday. Entire state north of a Laredo to CRP line may have ice accumulations.

SE TX update will be out by 500pm
Great, and I put off buying that generator. Is the existing moisture expected to be the source of the predicted ice event on sunday? or is it the low pressure expected to form over the northwest gulf after the low out west passes over? Also, when is the next surge of cold air arriving in central tx. Any ideas? Thanks.

I just took my daughter to and back from the ice rink here close to Cedar Hill. She had hockey today. On the way back I noticed ice on all vegetation and on vehicles that were not running. But I noticed a few of the pine trees and cedar trees over here are already bending significantly under the weight of only maybe an 1/8 inch of ice accumulation. If we get an inch solid of freezing rain, this could devestate trees and vegetation in the area and the effects would be seen for many years especially in foreseted areas. On our land in east texas, we can still see some of the effects of the ice storm that hit there -- I think in 2000 that one was. Some of the pine trees are bent or leaning still years later. But this storm... sounds like it could be a lot worse.

Well...I notice the Hight for Houston Downtown is now 24 on Tuesday...down 5 degrees from 39 this morning....and down 10 degrees from a couple of days ago.

Of course...I expect a nudge downward another 2 or 3 degrees.

M.L.King Day: Periods of rain. High near 37. North wind around 15 mph. Chance of precipitation is 80%.

Monday Night: Rain likely, mixing with freezing rain after 9pm. Cloudy, with a low around 29. Chance of precipitation is 60%.

Tuesday: Rain, freezing rain and sleet likely, mainly before 10am. Cloudy, with a high near 34. Chance of precipitation is 60%.

Tuesday Night: A chance of rain, freezing rain, or sleet. Cloudy, with a low around 29. Chance of precipitation is 30%.

If only this artic air was not so shallow, because then you would probably be getting mainly snow instead of ice. Snow is still dangerous to drive in, but not as bad as ice. I remember Christmas Eve 2004 before it turned to all snow here. We had nothing but sleet falling and big tree branches falling everywhere. It sleeted moderatly to heavy all Christmas Eve and Christmas morning and did not turn over to snow until around noon.

...WINTER STORM WATCH IN EFFECT FROM SUNDAY EVENING THROUGH
MONDAY MORNING...

THE NATIONAL WEATHER SERVICE IN SHREVEPORT HAS ISSUED A WINTER
STORM WATCH...WHICH IS IN EFFECT FROM SUNDAY EVENING THROUGH
MONDAY MORNING.

AN ARCTIC COLD FRONT WHICH HAS PUSHED THROUGH MUCH OF NORTHEAST
TEXAS...SOUTHEAST OKLAHOMA AND EXTREME SOUTHWEST ARKANSAS IS
EXPECTED TO BE REINFORCED BY YET ANOTHER VERY COLD AIRMASS SUNDAY
NIGHT ACROSS THE REGION. THIS AIRMASS HAS THE POTENTIAL TO BRING
TEMPERATURES NEAR OR BELOW FREEZING BEGINNING LATE SUNDAY NIGHT
AND CONTINUING THROUGH THE FIRST HALF OF THE DAY MONDAY. LIGHT RAIN
IS EXPECTED TO OVERRIDE THIS SECONDARY COLD AIRMASS AND IF
TEMPERATURES ARE BELOW FREEZING...THE RESULT WILL BE FREEZING RAIN
WHICH WOULD LEAD TO VERY HAZARDOUS DRIVING CONDITIONS. FREEZING
RAINFALL AMOUNTS ARE EXPECTED TO BE LIGHT...MAINLY LESS THAN ONE
QUARTER OF AN INCH. HOWEVER...IT IS UNCERTAIN AT THIS TIME THE
DEGREE OF THE COLD AIR AND JUST HOW MUCH RAINFALL THIS NEXT SYSTEM
MAY PRODUCE. FREEZING RAIN AMOUNTS IN EXCESS OF ONE QUARTER OF AN
INCH WOULD LIKELY RESULT IN ELECTRICAL OUTAGES FROM DOWNED TREES
AND POWERLIENS. FOR THIS REASON... PREPARATIONS NEED TO BE MADE ON
SUNDAY FOR A POSSIBLE FREEZING RAIN EVENT ACROSS MUCH OF NORTHEAST
TEXAS...SOUTHEAST OKLAHOMA AND SOUTHWEST ARKANSAS BEGINNING LATE
SUNDAY NIGHT AND CONTINUING THROUGH AT LEAST THE FIRST HALF OF
MONDAY.

A WINTER STORM WATCH MEANS THERE IS A POTENTIAL FOR SIGNIFICANT
ICE ACCUMULATIONS THAT MAY IMPACT TRAVEL. CONTINUE TO MONITOR THE
LATEST FORECASTS.

I don't think the front is moving eastward very much anymore.. actually I think it stopped any significant eastward movement sometime last night, but I guess it's still moving southward?

...THREAT OF WINTER WEATHER INCREASING ACROSS PORTIONS OF SOUTHEAST TEXAS
SUNDAY NIGHT INTO WEDNESDAY MORNING...

AN ARCTIC COLD FRONT WILL CONTINUE TO SLOWLY MOVE THROUGH SOUTHEAST
TEXAS TONIGHT...WITH THE COLDEST AIR EXPECTED TO ARRIVE LATE SUNDAY
AND PERSIST INTO THE MIDDLE PART OF NEXT WEEK.

PACIFIC AND GULF MOISTURE ALONG WITH EMBEDDED UPPER LEVEL DISTURBANCES
WILL CONTINUE TO OVERRUN THE COLD AIRMASS AT THE SURFACE AND WILL LEAD
TO PERIODS OF PRECIPITATION THROUGH WEDNESDAY MORNING. AS SURFACE TEMPERATURES
FALL BELOW FREEZING...THE THREAT OF ICE ACCUMULATIONS WILL INCREASE.

THOUGH WE WILL CONTINUE TO MONITOR THE LATEST DATA AND ADJUST THE FORECAST
ACCORDINGLY...THIS IS HOW THE SCENARIO IS CURRENTLY FORECAST TO EVOLVE:

TONIGHT...LOCALLY HEAVY RAINFALL IS POSSIBLE ACROSS THE NORTHERN PORTIONS
OF SOUTHEAST TEXAS...ROUGHLY ALONG AND NORTH OF A LINE FROM COLUMBUS
TO LIVINGSTON. RAINFALL ACCUMULATIONS OF 1 TO 3 INCHES MAY LEAD TO SOME
LOCALIZED FLOODING.

SUNDAY NIGHT AND MONDAY...LOCATIONS NORTH OF A LINE FROM BRENHAM TO
LIVINGSTON SHOULD SEE TEMPERATURES FALL BELOW THE FREEZING MARK IN THE
EVENING. WHAT WILL INITIALLY START AS RAIN WILL TRANSITION TO FREEZING
RAIN OVERNIGHT. LIQUID PRECIPITATION...POSSIBLY MIXED WITH A LITTLE
BIT OF SLEET...IS THEN EXPECTED FROM LATE MONDAY MORNING THROUGH THE
EARLY EVENING HOURS WITH TEMPERATURES JUST ABOVE FREEZING. AREAS TO
THE SOUTH SHOULD SEE RAIN.

MONDAY NIGHT...FREEZING TEMPERATURES ARE EXPECTED ACROSS ALMOST ALL
OF SOUTHEAST TEXAS EXCEPT LOCATIONS NEAR THE IMMEDIATE COAST. RAIN
SHOULD TRANSITION TO FREEZING RAIN AND SLEET THROUGH THE NIGHT.

TUESDAY...INLAND TEMPERATURES ARE EXPECTED TO HOVER AT OR JUST ABOVE
FREEZING RESULTING IN A MIX OF RAIN...FREEZING RAIN AND SLEET. COASTAL
LOCATIONS ARE EXPECTED TO REMAIN ABOVE FREEZING RESULTING IN ONLY RAIN.
IT APPEARS THE BEST AVAILABLE MOISTURE MAY GRADUALLY SHIFT SOUTHWARD
DURING THE DAY. LOCATIONS SOUTH OF A BRENHAM TO LIVINGSTON LINE SHOULD
SEE THE BETTER CHANCES OF PRECIPITATION THAN THOSE TO THE NORTH.

TUESDAY NIGHT...INLAND PRECIPITATION WILL ONCE AGAIN FALL AS FREEZING
RAIN AND SLEET AS SURFACE TEMPERATURES FALL BELOW FREEZING. AGAIN...AREAS
SOUTH OF THE LINE FROM BRENHAM TO LIVINGSTON SHOULD HAVE THE BETTER
CHANCES OF RECEIVING THE MORE SIGNIFICANT ACCUMULATING FROZEN PRECIPITATION.

WEDNESDAY...LINGERING SLEET AND FREEZING RAIN EARLY IN THE MORNING SHOULD
COME TO AN END AS TEMPERATURES WARM IN THE LATE MORNING AND AFTERNOON.
THIS SHOULD BRING AN END TO THE THREAT OF FROZEN PRECIPITATION.

THE THREAT OF SIGNIFICANT ICE ACCUMULATIONS ASSOCIATED WITH FREEZING
RAIN AND SLEET APPEARS TO BE INCREASING. ICE ACCUMULATIONS BETWEEN
1/4 INCH AND 1/2 INCH MAY OCCUR. IF THIS MATERIALIZES...DRIVING CONDITIONS
WILL BECOME EXTREMELY HAZARDOUS ESPECIALLY ON BRIDGES AND OVERPASSES.
IN ADDITION...TREES AND POWER LINES MAY COME DOWN. A WINTER STORM
WATCH MAY NEED TO BE ISSUED FOR NORTHERN PORTIONS OF THE SOUTHEAST
TEXAS LATER TONIGHT OR EARLY SUNDAY TO GIVE APPROPRIATE LEAD TIME
FOR THE UPCOMING THREAT. ADDITIONAL WATCHES MAY BE REQUIRED FURTHER
SOUTH FOR MONDAY NIGHT. WIND CHILL INDEX VALUES BETWEEN 20 AND 30
DEGREES ARE EXPECTED STARTING SUNDAY NIGHT...AND READINGS COULD GO
AS LOW AS 10 TO 20 DEGREES MONDAY NIGHT THROUGH WEDNESDAY MORNING.

RESIDENTS ACROSS SOUTHEAST TEXAS SHOULD TAKE ADVANTAGE OF THE REMAINING
WARM HOURS TO SHELTER SENSITIVE PLANTS AND PETS AND MAKE ANY OTHER PREPARATIONS
NECESSARY TO WINTERIZE YOUR PROPERTY. CHECK ON THOSE WITH SPECIAL NEEDS
AND THE ELDERLY TO MAKE SURE THEY ARE PREPARED SHOULD THIS WINTER WEATHER
EVENT MATERIALIZE. PRECAUTIONS SHOULD BE TAKEN BY THOSE THAT MUST VENTURE
OUTSIDE. IF YOU MUST GO OUTSIDE...WEAR PROTECTIVE CLOTHING TO STAY DRY
AND WARM AND MAKE CERTAIN ALL EXTREMITIES ARE COVERED.

PLEASE MONITOR THE LATEST UPDATED WEATHER FORECASTS THROUGH THE REMAINDER
OF THE WEEKEND AND ON INTO THE START OF THE UPCOMING WEEK.

I'm a little confused, why are most NWS calling for drier conditions by the middle of next week when models are showing more precip. falling Tuesday and Wednesday and possibly beyond? Just curious.

Assuming if there is an icestorm, the highs are rarely above freezing. I know that from experience. I think the highs will be no higher than 32.

Dangerous icing threat for SE TX Mon through Wed.

Winter Storm Warning issued for Austin metro area...Watches will be needed this evening or early Sunday for SE TX.

Crippling ice storm in progress over N TX into OK and SW into SW TX. Accumulations on the increase.

Discussion:


Very shallow (1000 ft thick) arctic air mass slowly pushing through SE TX. Front passed Brenham around 200pm and the temp fell from 70 to 54. Front has passed I-10 west of Houston and will reach Victoria likely before IAH. Front is being driven southward under its own density and expect it to clear the coast by sunrise Sunday. Secondary arctic push over OK will surge southward and arrive early Monday bringing sub-freezing temps. and ice into the area.

After reviewing the guidance this afternoon will stick close to the ETA as it seems to have the best handle. Will toss out the front moving back northward as a warm front and keep the area firmly in the cold sector on Sunday. By Monday the front should be into the offshore waters with the freezing line dropping southward.

May get some pretty good rain tonight and ongoing flooding N and W may push the Navasota and Colorado Rivers to flood stage. Rainfall has been quite impressive today along the I-35 corridor with widespread 3-5 inch amounts.

Precip/P-type:

Increasing threat of significant ice accumulation over SE TX include metro Houston. Once again will stick close to the ETA on P-type and timing onset of freezing rain and sleet. Will bring freezing line into the NW counties late Sunday and progress it slowly toward the coast during the day Monday with rain changing to freezing rain. ETA at noon Monday has surface temps. near freezing at IAH with the cold air about 2500 ft thick with quite warm conditions above the shallow cold dome...classic freezing rain setup.

Will start freezing rain and glazing over CLL to HUNTS (UTS) late Sunday and drop that line to Columbus to Conroe to Livingston Monday morning. Glazing of elevated objects should be expected along with bridges and overpasses.

Will start freezing rain late Monday afternoon along the US 59 corridor from Victoria to Sugarland to Humble and then drop the line southward to Port Lavaca to Bay City to Angleton to Pasadena to Winnie by Tuesday morning. Ice accumulation will begin Monday evening across the northern 1/2 of Harris County and overtake nearly the entire area by Tuesday morning.

Cold air continues to deepen over time with the ETA forecast sounding at IAH showing it 3300 ft thick by 600pm Tuesday and nearly 4000 ft thick by midnight Wednesday suggesting the freezing rain may begin to mix or change to sleet.

Accumulations:


Significant accumulations of ice are expected resulting in vegetation damage and downing of power infrastructure. Widespread ice accumulations of .25 to .75 of an inch will be common with some places likely along and N of I-10 seeing 1.0-1.5 inches of accumulation. Freezing rain/sleet mixture Tuesday evening will form a hard crusted layer on objects such as roads, cars, roofs. Trees will likely be at their breaking point by midday Tuesday and expect limbs to begin to break under the weight of the ice.

Travel:

Surface travel across the state is already nasty W of I-35 and will only worsen over time. Expect icing of bridges and overpasses to begin Monday morning N and W and progress into Harris County during the day. Expect all bridges and overpasses to be iced over Tuesday morning with accumulations starting on surface streets and freeway main lanes. Travel will be nearly impossible Tuesday and Wednesday even with sanding operations.

Aviation:

DFW and regional N TX airports will be heavily impacted tonight with rigorous de-icing in effect. Airport Weather Warning is in effect for DFW and if freezing rain overwhelms de-icing operations the airport may need to be closed. Onset of freezing rain at CLL, IAH, and HOB will result in rigorous de-icing procedures with heavy ice accumulation on aircraft controls through 2000 ft of ascent. Aircraft may be sent back multiple times to terminals to de-ice and expect long delays and numerous cancellations.

Residents should be prepared for an extended period of freezing temps., icing, and power disruption. Preparations to protect plants and pipes should be completed by sunset Sunday.

Public Forecast for Harris and Surrounding Counties:

Tonight: cloudy and warm early with an 80% chance of thunderstorms. Heavy rainfall possible. Temps. steady in the upper 60's then falling into the 40's by sunrise. Winds S 10-15mph shifting tot he north 15-25mph.

Sunday: cloudy, cold and wet with a 70% chance of rain and drizzle. Temps. falling into the upper 30's. N winds 15-20mph

Sunday night: cloudy and very cold with a 60% chance of rain changing to freezing rain (late) N and W. Temps. falling into the mid 30's. N wind 15-20mph

Monday: Winter Storm Conditions developing, Cloudy and very cold with temps. falling into the lower 30's. A 60% chance of rain changing to freezing rain. Ice accumulations of 1/10 to 1/4th of an inch. N winds 10-15mph

Monday night: Winter Storm/Ice Storm Conditions, Cloudy and very cold with near steady temps. in the upper 20's. A 60% chance of freezing rain mixed with sleet. Additional ice accumulation of 1/4th to 1/2 an inch. N winds 5-15mph.

Tuesday: Winter Storm/Ice Storm Conditions, Cloudy and very cold with near steady temps. around 30. A 60% chance of freezing rain and sleet. Additional ice accumulation of 1/4th to 1/2 of an inch. N winds 5-10mph.

Tuesday night: Winter Storm/Ice Storm Conditions, Cloudy and very cold with near steady temps. in the upper 20's. A 50% chance of sleet. Additional accumulations of ice (1/10th to 1/4th an inch) accumulations of sleet 1/2 to 1.0 inch.

Wednesday: Winter Storm Conditions, Cloudy and very cold with a 30% chance of morning sleet or snow. Near steady temps. in the low 30's. Sleet/snow accumulation less than 1/2 an inch.

NW DFW area still nada.

Just took a ride to wal-mart. Tons of people on the streets, light drizzle, no ice to speak of. Friends I have in the extreme NW zones reporting nothing as well. We finally hit 32 degrees just now.

If you're in Dallas or south or east of here, and waiting for the cold air, you've got a while to go, it's been above freezing here all day, and no sign of any frozen precip.

Our forecast for the day was 100% chance of frozen rain. Just goes to show how hard this event has been to nail down. I'm starting to wonder if our 100% chances of accumulations for tonight or tomorrow will even materialize.

Even though a watch is unlikely, not sure if the NWS has enough colors to keep up.

The second, colder, surge of air has not reached you yet. Once it does expect things to go downhill quickly (with temps. dropping even further). Also, now that you are at 32-degrees, any precip. from this point foward should be of the frozen variety tonight. Still looks like an ice storm is very likely for the Dallas area tonight through Monday.

BTW: Looks like other areas around you have not been so lucky thus far. Expect similar conditions to begin in your area soon..

OK everyone. I'm thinking this ice storm in Texas is all EWG's fault for praying one too many times to the Weather Gods for winter precip. :cheesy: :lol:

I feel very certain this ice storm will materialize for the Houston Metro area.

Luckily, just as we hit 32, the precip line moved past us. I see nothing else on radar coming this way.

Our forecast high was 31, we hit 36. That 5 degree error margin made all the difference in the world as far as our weather today.
