AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DENVER CO
300 PM MDT WED OCT 28 2009

.SHORT TERM...THIS HAS CERTAINLY BEEN AN INTERESTING STORM SO FAR
AND ALL THE LATEST INFORMATION SUGGESTS IT HAS A LONG WAY TO GO
BEFORE BEING OVER. THE MAIN UPPER LEVEL LOW HAS BEEN DRIFTING SLOWLY
EAST TODAY AND THE 500 MB LOW IS ONLY NOW JUST APPROACHING THE FOUR
CORNERS. THERE HAS BEEN AN ELONGATED LOOK TO THE SYSTEM SO FAR AND
AS A RESULT THE ACTION HAS BEEN FOCUSED ALONG THE URBAN CORRIDOR AND
FOOTHILLS SO FAR WITH GOOD NE FLOW JUST ABOVE THE SURFACE AND
GRADUALLY DEEPENING WITH TIME AS REVEALED BY SEVERAL PROFILERS IN
THE AREA. FARTHER EAST VERY LITTLE HAS HAPPENED...WITH DIA NEAR THE
EDGE OF THE ACTION SO FAR. THE AMOUNTS OF SNOW THUSFAR HAVE BEEN
MOST IMPRESSIVE DESPITE THE SYSTEM STILL SO FAR OFF AND THE
ELONGATED LOOK TO IT...WITH GENERALLY 8 TO 12 INCHES ALONG THE URBAN
CORRIDOR AND ANYWHERE FROM 15 TO 25 INCHES IN THE FOOTHILLS. ALL
THE MODELS CONTINUE THE NORTHEAST FLOW AT 700 MB THROUGH TONIGHT AND
NOW WELL INTO THE MORNING FOR MOST OF THE FRONT RANGE. WITH THIS IN
MIND WE COULD EASILY DOUBLE WHAT WE HAVE SEEN SO FAR ALONG THE FRONT
RANGE AND HAVE INCREASED TOTAL SNOWFALL AMOUNTS TO REFLECT THIS.
DESPITE ALL THE SNOW THE MAIN ROADS HAVE REMAINED GENERALLY WET SO
FAR WHICH OFTEN HAPPENS THIS TIME OF YEAR WITH TEMPS IN THE UPPER
20S OR SO IN THE DAYTIME. BUT AS THE SUN GETS LOWER EXPECT THINGS
TO GO DOWNHILL AND COUPLING THIS WITH AN INCREASE IN SNOWFALL THAT
IS SEEN NOW APPROACHING THE DENVER AREA FROM THE SOUTH IT COULD BE A
DICEY RUSH HOUR. IT DOES NOT LOOK GOOD FOR THURSDAY MORNING
CERTAINLY GIVEN THE SLOWER MOVEMENT OF THE SYSTEM.

AS NOTED ABOVE THINGS GET BAD ON THE PLAINS TONIGHT AND CONTINUE
THAT WAY TOMORROW. THE LATEST NAM IS NOTABLY SLOWER THAN THE 12Z
RUNS AND IF THIS TREND CONTINUES THERE COULD BE SOME VERY IMPRESSIVE
AMOUNTS ON THE PLAINS AS WELL...WITH SOME AREAS CERTAINLY EXCEEDING
A FOOT OF SNOW. AS THE UPPER LOW SHIFTS EASTWARD NORTHERLY WINDS
WILL INCREASE AT LOWER LEVELS ON THE PLAINS LATER TONIGHT AND
TOMORROW AND WILL LIKELY SEE BLIZZARD CONDITIONS DEVELOPING WITH
ROAD CLOSURES. THOUGHT ABOUT HOISTING A BLIZZARD WARNING BUT WITH A
TREND TO SLOWER THESE CONDITIONS MAY WAIT UNTIL MORE DURING THE DAY
TOMORROW SO TIME FOR THE NEXT SHIFT TO SEE WHAT THE 00Z MODELS SHOW
AND GO FROM THERE.

.LONG TERM...MAIN UPPER LEVEL LOW WILL MOVE AWAY FROM THE AREA THU
NIGHT HOWEVER LINGERING MOISTURE AND FAVORABLE QG ASCENT WILL STILL
AFFECT THE PLAINS THU EVENING. THUS COULD STILL HAVE SOME PROBLEMS
WITH SNOW AND BLOWING SNOW EAST OF A FORT MORGAN TO LIMON LINE THRU
06Z OR SO. IN THE MTNS EXPECT SOME OROGRAPHIC -SHSN THU NIGHT. BY
FRI NLY FLOW ALOFT WILL BE OVER THE AREA. SOME MOISTURE WILL LINGER
IN THE MTNS AND WITH WNW 700 MB WINDS MAY SEE A CHC OF OROGRAPHIC
-SHSN. ELSEWHERE IT WILL BY DRY. MAIN PROBLEM FOR NERN CO WILL BE
HIGH TEMPS DUE TO SNOW COVER. 850 TEMPS WILL NOT RISE MUCH ON FRI
DESPITE WARMING AT 700 MB THUS LOW LEVEL INVERSIONS MAY BE IN PLACE
ESPECIALLY ALONG THE PLATTE RIVER VALLEY. CURRENT GUIDANCE TEMPS
ARE IN THE LOW TO MID 40S WHICH COULD BE FROM 5 TO 8 DEGREES TOO
WARM IN SOME AREAS.

FOR SAT MAINLY DRY NW FLOW ALOFT WILL BE OVER THE AREA WITH 850-700
MB TEMPS RISING FROM 5 TO 6 DEGREES C. LINGERING SNOW COVER COULD
STILL INFLUENCE HIGHS IN SOME PLACES. FOR NOW WILL KEEP HIGHS IN
THE UPPER 40S TO LOWER 50S OVER THE PLAINS. BY SUN LATEST GFS SHOWS
A WEK UPPER LEVEL TROUGH MOVIGN ACROSS IN NW FLOW ALOFT.
CROSS-SECTIONS DO NOT SHOW MUCH MOISTURE WITH THIS FEATURE FM SAT
NIGHT INTO SUN SO WILL ONLY MENTION LOW POPS IN THE MTNS. OVER NERN
CO A WEAK FNT WILL MOVE ACROSS ON SUN SO THIS COULD ALLOW FOR TEMPS
TO BE A FEW DEGREES COOLER THAN SAT.

FOR MON INTO TUE A FLAT RIDGE WILL BE OVER THE AREA WITH DRY WLY
FLOW ALOFT. 850-700 MB TEMPS WILL CONTINUE TO RISE ANOTHER 6
DEGREES OR SO ON MON AND ANOTHER DEGREE OR TWO ON TUE. THUS SHOULD
SEE HIGHS RISE BACK TO OR SLIGHTLY ABOVE NORMAL WITH READINGS AT OR
ABOVE 60 DEGREES. LITTLE CHANGE EXPECTED FOR WED WITH DRY
CONDITIONS AND TEMPS MAINLY IN THE 60S ACROSS THE PLAINS.


&&

.AVIATION...SNOW SHOULD INCREASE SOON AT DIA AND APA AS AN EXPANDING
AREA OF MODERATE SNOW TO THE SOUTH IS WORKING NORTHWARD. CONTINUE
GENERALLY MODERATE SNOW AT BJC THROUGH THE NIGHT INTO THURSDAY
MORNING...PERHAPS WITH SOME HEAVY SNOW AT TIMES. THE SNOW MAY
DECREASE SOME AFTER THIS NEXT BURST AT DIA AND APA THEN PICK UP
LATER. AT DIA THE WORST COULD BE ON THURSDAY AS THE SYSTEM WINDS UP
OVER EASTERN COLORADO WITH WINDS PICKING UP AND MODERATE TO EVEN
HEAVY SNOW AT TIMES POSSIBLE. ALL THIS COULD LEAD TO BLIZZARD
CONDTIONS AT DIA...NOT AS BAD WIND WISE OF COURSE APA AND LIKELY
EVEN LESS WIND AT BJC. SNOW TOTALS BY LATE THURSDAY COULD BE NEAR A
FOOT AT DIA...MORE AT APA AND BJC...WHICH IS CLOSE TO A FOOT
ALREADY.

Double the 14" I already have? Awesome!

[Dencolo]

Parts of the discussion above are hard to believe. This is the biggest snowstorm I've seen since I've lived in Denver (moved here early 2007).

[PTPatrick]

I was a little surprised on the ride home that roads werent too bad, but I guess the october sun angle does a number on the pavement. In any case it definately looked like more as I got further west...I work in East Denver where there was probably 8', but 3 miles west there was 11 in my yard...and that is east of 25. So I could believe the hefty totals already coming out of littleton and lakewood. In any case, this is definately the biggest one since Dec '06. That was my first winter storm here and I got 28 inches. I suspect we wont quite get that much here downtown but 28 in Littleton seems reasonable. 20-22 sounds pretty reasonable for downtown given the duration issue and that much of the peak of the storm will happen after sundown. One thing is for sure the roads shouldnt be near as bad as the Dec 06 storm. There does seem to be wide arrays in the amounts though on different surfaces...guess that is probably some melting and of course wind.

[SCMedic]

Radar echos not overly impressive, but I have a feeling there is some deflection going on. Another 10-15" would be damn impressive. Roads are going to get crappy in a bit.

[PTPatrick]

It has let up a lot downtown in the past little bit. But think its normal for these things to come in waves. Looking at some of the maps on HPC it seems like rather than just one big low the SW just keeps spitting out little ones, with the grandaddy back in the 4 corners. I think today was round 1. I'll admit, I am skeptical of the possibilities of of another 10-15 too. Certainly if some weird dynamics(which I dont totally understand) occur, we could end up never seeing much more heavy precip and just a bunch of light to moderate stuff that doesnt pile up. (18z GFS didnt look as robust as the NAM). I dont think we will know til it happens though. Point forecast for me says 5-9 more tonight for me and 3-7 more tomorrow.

[SCMedic]

That's still a monster storm if that pans out. I already have 15" in my yard.

[PTPatrick]

SC are you in broomfield right? It would in deed be a crazy storm for Ocotber, definately one for the record books if we get 2 ft downtown. There have only been 7 storms since 1946 that passed the 20 inch mark in Stapleton...but more than likely Stapleton area will come in a hair under 20. Even the infamous stomr of 1997 in october was officiallyonly 21.9 at Stapleton, and that shut the city down for a day or so.

Meanwhile, Snow has picked up quite a bit here downtown again and getting VERY windy. Can here it whistling through this old house.

[SCMedic]

Yup. Broomfield. Coming down pretty well again.

COCORAHS REPORT

[Stephanie]

I just sent an e-mail to my father that's in Rye, CO and his girlfriend that's in Denver, west of I-25, to see how they're making out. VERY impressive!

[Dencolo]

14" in Littleton. Coming down heavy again after a little break. The roads are not too bad yet - slushy but not snowpacked. That should chande as temps drop further.

[somethingfunny]

Lucky!!!!!

What an incredible storm. Please post pictures as soon as you can, Coloradans! (is that right?)

[Scott Patterson]

This storm was really hit and miss in Colorado.

Craig got less than two inches and it didn't last that long (there is only a little left).

Just to the south, the area just north of Meeker all the way down to Rifle on I-70 got pounded. I had to travel to the Meeker area for work. Just south of Meeker they probably got a foot.

It sounds like the same story in other areas of the state and was similarly spotty. The Front Range got pounded, but many of the mountain areas were missed. Keep this in mind before breaking out the skis.

[PTPatrick]

Coming down moderate pace in Denver. Roads were icy on the way home from dinner, not snow packed though. Interestingly enough had about 2 new inches of snow where I had previously shoveled, but measured back at the same spot in the yard and only about 11 inches. So I guessing there might be a little melting happening under the snow.

[PTPatrick]

Latest NAM has only about .25-.5 inches of precip left for the 0z-18z period. At the high end that would probably be about 8 inches(slightly higher than 10:1 snow ratio. Having said that...the models really didnt predict what has happened so far all that well, at least in terms of snow totals, so I dont think there is much reason to believe it now.

[Dencolo]

Latest snow totals. I don't know how 9news has snow totals as of 10pm when it's not 10pm yet, but here it is. Look at DIA and it's 6". Can you believe that is the official place Denver records its snow (someone correct me if I'm wrong)? I'm probably around 17" now just 15 miles SW of downtown. These #s suggest more of an elongated storm favoring the middle of Denver and to the West. Places like Elizabeth and Parker that can often get hammered on the Southeast side definately aren't feeling the brunt yet.

In deed it is VERY rare for Dowtown to out do the SE suburbs. We are at 13 now in my yard downtown...while Elizabeth has but 6. That is crazy. Sounds like downtown also has done better or about as well as DTC area, which is also unusual. I think those areas will get hit more tomorrow with the N wind though verses the E to NE we have had all day. I would be suprised for SE aurora to get a heavy burst as Boulder's snow dies down. AND YES...it is crazy for them to be measuring Denver's snow at DIA. Perhaps this will make them realize how absurd it is and how much it will screw up Denvers snow records.

First post on Denver winter thread. Fort Coliins 13" @ 4:30, 16" @ 9:00. Measured in wide open flat lawn area.

Freaky big snow seems to follow me. Lived in Wheaton, IL in 1967 for the Chicagoland record 23", lived in Raleigh in 2000 for the record 20" snowfall.

I have lived in Fort Collins since June. Double the current 16" and Holy Snowmen! Now that would be a weather story to tell a few times.

This WSW is for all of us in the urban corridor. Should be interesting when I wake up tomorrow!
