Could someone run a GFS Sounding(and brief analysis)from today's 12z run for Texarkana, Thanks.

Can't post images on phone but from everything I see Texarkana is on the same boat as DFW. Everything looks similar except timing. Sleet and snow being the dominant type could be several inches. Im not sure why watches aren't up yet for you guys given its a fairly confident forecast.

Update from jeff:

Winter Storm heading for TX early next week….possible second winter storm late next week.

Ingredients appear to be coming together to produce a round of winter precipitation across a large part of TX and portions of SE TX Monday and Tuesday. Overnight model guidance has not changed much with respect to the expected surface temperatures (thus there has been no real cooling or warming trend on the model output). Confidence has increased however that the surface freezing line will in fact push into SE TX late Monday afternoon and early evening be driven by cold air advection across what by that time will be an ice/sleet covered north TX. Models also continue to show a very significant warm nose (layer of warm air) a few thousand feet above the surface with the latest NAM model showing temperatures pushing 50 degrees atop the very cold surface layer…this suggests rain drops will be falling to the surface with a “warm” temperature…likely well above freezing and will have to cool to the surface temperature over time. The NAM also now shows the surface freezing line progressing as far south as I-10 Tuesday morning…for now will discount this model as a colder outlier in favor of the slightly warmer GFS and ECMWF models.

There will be little to no room for evaporative cooling as the air mass will saturate tomorrow behind the front and remain saturated through the period…this leaves only cold air advection to cool the surface temperature to freezing or below. Best chances of surface temperatures falling to freezing Monday evening will be along and north of a line from College Station to Conroe to Cleveland and this will support a change of light rain/drizzle to freezing light rain/freezing drizzle. QPF amounts are forecasted in the .05 to .10 of an inch range within the sub-freezing air mass suggesting some ice accumulation on elevated surfaces is possible. Current QPF amounts suggest a Winter Weather Advisory or Winter Storm Watch may be needed for the counties of: Burleson, Madison, Walker, Trinity, Polk, and San Jacinto on Sunday with the critical time period being Monday evening after 600pm through about 1000am Tuesday morning.

South of a College Station to Conroe to Cleveland line surface temperatures are still expected to remain above freezing suggesting no change to freezing rain or ice accumulation. Would not at this point rule out any southward shift in the freezing line over the next 48 hours, but there is no strong indication at this moment that freezing rain/drizzle would impact Harris County or the metro Houston area. Lows Tuesday morning across Harris County will likely range from 33-35 degrees.

Accumulations:
Ice accumulation will be possible north of a line from College Station to Conroe to Cleveland Monday night and Tuesday morning and most likely north of a line from Caldwell to Huntsville to Livingston where surface temperatures will likely be closer to 30. Tough call on accumulations given the very warm temperatures aloft and only 30-32 at the surface. Elevated surfaces such as trees and power lines will likely see some accumulations with bridges and overpasses a little tougher call. General thinking right now is less than .10 of ice accumulation, but a degree or two colder could make for better accumulation potential especially on the elevated bridges and overpasses. No ice accumulation is currently expected in Harris County.

As with all winter weather events there is a high degree of uncertainty and with this event in particular much depends on 1-2 degrees making a big difference between ice and no ice. No other P-type (sleet or snow) is expected across SE TX with the impressive warm layer aloft.

Late Next Week:
Another strong arctic cold front looks to cross the area late Thursday and then a storm system approaches from the west Friday/Saturday with the cold air in place. Could once again be dealing to P-type concerns across a large part of TX including portions of SE TX next Friday evening into Saturday.

Will likely see winter weather products issued Sunday for portions of the area as well as surrounding portions of C and N TX to match with the Winter Storm Watch already issued for a large portion of N TX. Travel to N TX is strongly discouraged after noon on Sunday as ice and sleet begin to accumulate over that portion of the state. Little to no improve to surface travel is expected over N TX until after noon on Tuesday resulting in a prolonged period of impact.

Don't travel to North Texas after noon? Thought freezing precip was starting around 6:00 pm Sunday evening. What did I miss?

WINTER STORM COMING FOR ALL OF THE ARKLATEX MONDAY!!! Here are possible impacts: North- SW AR/SE OK/NE TX: Expect freezing rain Sunday evening-Sunday night then mainly sleet and snow Monday. (This includes Texarkana) Central: ETX & NW LA: Expect rain Sunday evening then a break. Freezing rain mixes with sleet Monday & Monday night. (This includes Shreveport-Bossier). South Deep ETX & W LA: Expect Freezing rain Monday and Monday night. Biggest issues could occur here due to ice accumulation on trees. (This includes Center, Mansfield,Many, Coushatta & Natchitoches) The maps show Snow/Sleet accumulation and Ice accumulation. Areas of snow accumulation closer to 3" will see mainly snow. Areas that get more sleet mixed with snow will get closer to 1". Areas of ice accumulation of over 1/2" will get mainly freezing rain. Areas of ice accumulation of 1/10 to 1/4" will get mix of sleet and freezing rain.

12Z GFS came in colder aloft. The "warm nose" is right at 32F in both Dallas & Texarkana Monday. By Tuesday morning, temps warm above the surface. You could see the precip start as sleet/snow then change to sleet on Tuesday.

I am so sick of the cold weather and ready Spring 2015. Just perhaps we may see Winter precip next weekend for the Houston area.

As mentioned by orangeblood earlier don't lose thought of the late week system. This is when the main storm comes out and will be a huge weather maker that will lay down the glacier, lots of details to work out but once our early week storm is done need to refocus.

Snowfall and ice potential for the Ark-La-Tex from Todd Warren:

I'm sure some of that snow accumulation will be sleet:

This doesn't look good for deep East Texas >.50 ice accumulation equals major power outages:

Has anyone seen the last 2 SREF? 9z had .75 QPF 15z had close to 1" :eek: If that verified this could rival 2013's sleet storm. :eek:

:uarrow: If a repeat of Dec. 2013 happens, I sure hope it is does indeed prove to be sleet and not freezing rain. While that storm left upwards of four to five inches of sleet along portions of the Red River Valley, about an hour to the east in Lamar County (Paris), the freezing rain did severe ice storm damage there.

Sleet can mess driving up for a day or two. But freezing rain can mess up the power grid for a lot longer. The Dec. 2000 ice storm up here left some people w/out power for as long as four or five weeks.

Agreed. Freezing rain wouldn't be an enjoyable event, but from what I am seeing, it doesn't look like a big freezing rain event here. As of right now, I'd say mostly sleet with some snow mixed in.

Of course, we're still 24 hours away. We'll see what happens.

Yeah soundings don't support much of freezing rain at least in NTX. Warm nose isnt warm enough or sizeable enough. Lower level cold isnt too shallow and its very cold.

I'm still not sold on there being enough moisture to support a winter storm warning, maybe just a winter weather advisory. Guess we will find out soon as the afternoon package comes out.

Wichita county seems to always gets left out of any reports or maps. We are too Northwest of Ft. Worth and too South of Norman.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE AUSTIN/SAN ANTONIO TX
237 PM CST SAT FEB 21 2015

.SHORT TERM (TONIGHT THROUGH SUNDAY NIGHT)...
CLOUD COVER ONCE AGAIN NEARLY BISECTS THE CWA FROM WEST TO EAST
WITH ABUNDANT LOW-LEVEL MOISTURE CONTINUING ACROSS THE EASTERN
COUNTIES. THE SURFACE LOW WHICH CAUSED THE BREEZY SOUTHERLY FLOW
FOR US YESTERDAY HAS SINCE SHIFTED EAST AND MUCH CALMER WINDS ARE
IN PLACE. THE INITIAL WIND SHIFT ON THE BACKSIDE OF THE SURFACE
LOW IS CURRENTLY BEGINNING TO MOVE THROUGH OUR NORTHERN
ZONES...BUT COOLER TEMPERATURES ARE LAGGING BEHIND. THE ACTUAL
ARCTIC COLD FRONT WE HAVE BEEN ADVERTISING REMAINS WELL NORTH OF
THE REGION AND CAN BE SEEN BY THE SURFACE HIGH BEGINNING TO ENTER
THE CENTRAL PLAINS. AS THE INITIAL WIND SHIFT ENTERS THE EASTERN
ZONES THIS AFTERNOON...THERE COULD BE AN ISOLATED SHOWER...BUT
HIGH-RES MODEL GUIDANCE IS NOT TOO KEEN ON THIS OUTCOME. WILL
KEEP A 20 POP FOR SHOWERS FOR THE EASTERN COUNTIES TO ACCOUNT FOR
ANY STRAY SHOWER ACTIVITY.

THE ACTUAL ARCTIC FRONT IS SCHEDULED TO ARRIVE TO THE AREA
TOMORROW EVENING AND POSSIBLE LIGHT RAIN WILL BEGIN DURING THE
DAY. THE BULK OF THE ACTIVITY WILL GET GOING AFTER THE COLD AIR
ARRIVES WHEN THE BEST OVER RUNNING COMMENCES. 12Z UPPER AIR
ANALYSIS SHOWED THE STRENGTHENING WEST COAST RIDGE AND TROUGH TO
ITS EAST DEEPENING. TEXAS IS THEN PLACED IN 40 TO 50 KNOTS OF FLOW
AT 500 MB. THERE IS ALSO AN EMBEDDED DISTURBANCE EXPECTED TO MOVE
THROUGH THE AREA IN THE SOUTHERN FLOW THAT WILL AID WITH THE
LIFTING FOR UPWARD MOTIONS. FORECAST SOUNDINGS SUNDAY NIGHT SHOW A
WARM NOSE ABOVE THE FRONTAL INVERSION WITH TEMPERATURES ABOVE 11C.
THIS WILL DO A GOOD JOB PREVENTING SLEET FROM FALLING IN OUR
CWA...SO OUR MAIN FOCUS WILL THEN SHIFT TO THE FORECAST FOR
SURFACE TEMPERATURES ACROSS THE AREA. THERE CONTINUES TO BE
DISCREPANCIES WITH SOME OF THE MODEL GUIDANCE DEPENDING ON WHICH
ONE YOU ARE LOOKING AT SO WE WILL TRY TO DISCUSS SOME OF WHAT WE
SEE. THE GFS AND ECMWF REMAIN THE WARM OUTLIERS WITH 12Z MONDAY
TEMPERATURES REMAINING ABOVE FREEZING FOR THE ENTIRE AREA. THE
NAM/CANADIAN HAVE THE FREEZING LINE INTO THE NORTHERN HILL COUNTRY
AT THAT TIME AND THE SREF IS EVEN A BIT FARTHER SOUTH. AS YOU CAN
SEE THERE ARE VARYING DIFFERENCES LOOKING AT THE GUIDANCE. DIVING
FURTHER INTO THE GFS WE CAN LOOK AT THE GFS ENSEMBLES. THIS SHOWS
US THAT THE WARMER GFS TEMPS ARE ACTUALLY IN THE UPPER QUADRANT OF
ALL THE MEMBERS AND MANY OF THE GFS ENSEMBLE MEMBERS ARE ABOUT 3
DEGREES COLDER ON AVERAGE. THIS GIVE US MORE CONFIDENCE WITH
GOING WITH THE COLDER CAMP AND THUS OUR TEMPERATURE FORECAST
LEADING UP TO MONDAY MORNING WILL FOLLOW CLOSELY TO THE NAM WHICH
IS A GOOD BALANCE TO THE SREF AND THE CANADIAN. THEREFORE WILL
MENTION FREEZING RAIN IN THE FORECAST AFTER 3AM FOR AREAS NORTH OF
A JUNO TO KERRVILLE TO BURNET LINE. IF THE SREF AND CANADIAN
VERIFY...THIS LINE MAY NEED TO BE SHIFTED A BIT FARTHER SOUTH AND
EAST.

&&

.LONG TERM (MONDAY THROUGH SATURDAY)...
AS WE GET INTO MONDAY THERE IS INCREASING CONCERN THAT
TEMPERATURES WILL STAY STEADY OR PERHAPS EVEN FALL A COUPLE OF
DEGREES WITH CONTINUED COLD AIR ADVECTION. FORECAST SOUNDING ALSO
SHOW SOME ROOM FOR A BIT OF EVAPORATIVE COOLING...BUT ONLY A
DEGREE OR TWO. THEREFORE WILL MENTION FREEZING RAIN FOR THE
PREVIOUS AREA THROUGH NOON AND FREEZING RAIN OR RAIN FOR THE MOST
LIKELY AREAS TO REMAIN BELOW FREEZING THROUGH THE AFTERNOON HOURS.
IF TEMPERATURES FALL ABOUT 3 DEGREES DURING THE DAY...AUSTIN COULD
BE CLOSE TO FREEZING AS EARLY AS MONDAY AFTERNOON. THIS IS LOW
PROBABILITY BUT NEEDS CLOSE WATCHING. THE NAM FORECAST SOUNDINGS
DO SHOW THE LAYER UNDERNEATH THE WARM NOSE GETTING TO -6C TO -7C
AND THERE COULD BE SOME SLEET MIXING IN. THINK THE WARM NOSE WILL
BE TOO MUCH TO OVERCOME AND OPTED TO JUST KEEP THE FORECAST SIMPLE
AND MENTION FREEZING RAIN AS THE SOLE WINTER WEATHER TYPE.

TEMPERATURES WILL CONTINUE TO DROP SLOWLY AS WE GET INTO MONDAY
NIGHT...AND THE THREAT AREA FOR FREEZING RAIN COULD EXPAND A BIT
TO THE SOUTH AND EAST. THE MAIN QUESTION THEN CHANGES TO HOW MUCH
PRECIPITATION WILL BE CONTINUING AT THE TIME MORE OF THE AREA IS
BELOW FREEZING. WE TALKED YESTERDAY ABOUT MORE LARGE SCALE FORCING
FOR ASCENT DURING THIS PERIOD BUT MODEL GUIDANCE HAS PUSHED THIS
BACK IN TIME A BIT FURTHER AND THUS THE MAIN IMPETUS FOR
PRECIPITATION DEVELOPMENT WILL BE CONTINUED WEAK ISENTROPIC LIFT
ON TOP OF THE FRONTAL LAYER. THIS LIFT WILL BE BECOMING WEAKER AND
MOST MODEL GUIDANCE SHOWS ONLY A FEW HUNDREDTHS OF AN INCH OF
LIQUID EQUIVALENT WHICH SEEMS REASONABLE. HOWEVER...IF THESE LIGHT
AMOUNTS FALL ON A GROUND WHICH IS NO LONGER WARM ANYMORE THERE
COULD BE MINOR IMPACTS ON ELEVATED SURFACES. IF TEMPERATURES GET
INTO THE UPPER 20S ACROSS THE HILL COUNTRY...THERE COULD BE A BIT
MORE IMPACTS IN THIS REGION. HAVE MENTIONED FREEZING RAIN FOR
AREAS NORTH OF A ROCKSPRINGS TO BOERNE TO GIDDINGS LINE MONDAY
NIGHT AND TUESDAY MORNING. THE ENTIRE AREA SHOULD WARM ABOVE
FREEZING BY LATE TUESDAY MORNING AND REMAIN ABOVE FREEZING THROUGH
WEDNESDAY...ENDING THE THREAT FOR WINTER PRECIPITATION.

TO SUMMARIZE...THE MAIN FOCUS FOR THE NEXT 48 TO 72 HOUR WILL BE
THE TEMPERATURE FORECAST ACROSS THE AREA WHILE THERE IS
PRECIPITATION FALLING. OUR GREATEST CONFIDENCE AREA OF SEEING
FREEZING RAIN WILL BE IN THE NORTHERN HILL COUNTRY AND THIS AGREES
WELL WITH THE LATEST WPC ICE PROBABILITY MAPS. ICE ACCUMULATIONS
SHOULD REMAIN LIGHT GIVEN THE WARM TEMPERATURES TODAY...STRENGTH
OF THE WARM NOSE AND TEMPERATURES BEING MAINLY IN THE 30-32 DEGREE
RANGE. WE WILL CONTINUE TO WATCH TEMPERATURE TRENDS CLOSELY AS ANY
DEVIATIONS COULD LEAD TO ADDITIONAL IMPACTS. RESIDENTS SHOULD
CHECK BACK FOR THE LATEST FORECASTS OVER THE NEXT 24 TO 36 HOURS AS
THINGS CAN CHANGE.

THE BASE OF THE TROUGH AND THE BEST UPPER SUPPORT WILL ARRIVE
ACROSS THE AREA BY TUESDAY NIGHT AND RAIN CHANCES WILL CONTINUE IN
THE FORECAST THROUGH WEDNESDAY AFTERNOON. THE FORECAST CONTINUES
TO HAVE LOW CONFIDENCE REGARDING THE LATE WEEK FRONT. THE 12Z
GFS BRINGS ANOTHER STRONG FRONT INTO THE AREA BY EARLY FRIDAY
WHILE THE ECMWF IS MUCH WEAKER WITH THE FRONT. IF THE GFS VERIFIES
WE WILL HAVE TO WATCH TEMPERATURES CLOSELY ONCE AGAIN...BUT THINGS
ARE LIKELY TO CHANGE OVER THE NEXT SEVERAL DAYS.
