Well last night's GFS brought some hope for snow in about a week in most of Western Oklahoma (mainly an inch or less), but this morning it is gone. Around Thanksgiving highs could be held down into the 40s, but nothing major. Things look to be pretty reasonable temp wise. Only major precip chances for Central OK looks to be Sunday the 20th into the first part of Monday the 21st. Could have some stronger storms but no winter precip as it looks now.

Quick update on precip chances...

Sunday -- Very light rain in far eastern and SE OK.

Monday -- Rain expands in mostly Central and East and later out west. Focal point will be roughly just along and south of I-44 for most of the day. Rain amounts in this area will be 0.50 to 1.50" of rain, with isolated higher amounts. Elsewhere less than a half inch and lower as you go more NW.

Tuesday -- Rain starts to move out. Light to moderate rain in Southeast OK. There will also be rain in far Northern Oklahoma. Temps will be in the mid 30s there, but temps higher up will be well above freezing so everything should stay liquid. If colder air works down we could see some snow flakes, but it is looking highly unlikely.

More updates on the longer term forecast once the rest of the GFS run is in.

Okay here is the long range forecast update...

I'mmmmmmmm dreaming.....of a white....thanksgivinnnnnnnnnggg...Okay well maybe not - on Thanksgiving. ;-)

I'll get to that here in a few. Here is the extended precip forecast going forward.

Friday Nov 25 - Slight chance of light rain in Southeast OK.

Saturday Nov 26 - Cold air I've been hinting at finally breaks a piece off and heads in. Upper level air temps will be well below free and stay below freeing most of Saturday. Light precip will move into Oklahoma early and linger. Liquid precip amounts will be light...less than 0.10" south of I-40, and up to 0.25" north of I-40. Rain will mix with snow over most of Oklahoma the way it looks now. The area that will have the highest probability of seeing all snow and a light dusting would be North Central and Northwest Oklahoma.

Sunday Nov 27th - Light snow will continue across Eastern Oklahoma. Lows will be around 30 and highs only in the mid to upper 30s. Don't expect much to stick, but enough in the air to get people in mood for the season. Look for very light accumulations of less than 0.10" liquid...or less than an Inch of snow.

Side note. This system will move out into the Ohio Valley and Lower Lakes and begin to transfer energy off the coast to form another Nor'easter. GFS isn't forecasting pulling the cold air down enough to keep everything all snow, but I would almost expect it to be except for right along the coast. So expect some areas to see 6-12 inches and isolated areas over a foot.

Thursday Dec 1 - Light rain possible in far Southern and Southeast Oklahoma. May see a couple snow flakes mixed in, but mostly just rain.

This morning's model run keeps us dry...so we'll just wait and see what happens as we get closer.

One thing that is on track is the first week of December being cold in most areas. While longer range GFS is highly inaccurate most times, it still gives us an idea of what might happen. Highs on December 2nd for example is now shown to not get out of the upper 20s for Central OK.

OU has played so many night games this year that fans, players and administrators were starting to complain. OU worked a deal with the TV folks so they could change the time. For some of the road night games OU wasn’t getting back to Norman until 4 am. It’s also not a great idea to play at night in late November because of cold and the threat of ice or snow. But I’m well quipped and will be there regardless of the weather. But I would rather be comfortable.

Why this is in the weather thread I have no.clue but first off, OU fans would have nothing to do with the game time decision. Its at OSU first off so they can deal with whatever time the game is to be played at. Second off, its on December 3rd this year.

As far as the first part of this week. Looks like the heavy rain will be confined to eastern Oklahoma. Half inch or less west, up to an inch Central (maybe more in isolated downpours) and 2+ east.

I don't usually watch the late local news, but channel 4 after the game had their predictor whatever thingy saying okc metro would get 1.8 inches in the next 36 hours or so. it showed much more rainfall than that in the SE part of the state. any ideas if this is extreme?

venture
11-21-2011, 02:00 AM
Depends on which you go with.

NAM: West - 0.50" or less, Central - 0.50" to 1.00", East - 1.00 to 2.25" (highest Northeast)
GFS: West & North - 0.25" or less, Central 0.50" to 2.25", East - 2.00" to 3.50" (highest East Central & Southeast)

The GFS pulls a little finger of higher precip back through like Tulsa and the north sides of the OKC metro area. Most of the precip bands are aligned on a Northeast to Southwest type diagonal line, but the estimates above tend to cover it. Highest values then to be in the southern/eastern areas of each region. Lowest values north and west.

I would say take the average and of the two and that gives a good idea of what we could expect.

Slight Risk of severe weather today. The risk area is south of I-44 from the OK/MO border to OKC and south of I-40 from OKC to the TX border. Large hail is the threat in this area.

DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1021 AM CST MON NOV 21 2011

VALID 211630Z - 221200Z

...THERE IS A SLGT RISK OF SVR TSTMS ACROSS PARTS OF TX/OK/AR/LA...

...NORTH TX/SOUTHERN OK...
A PAIR OF POWERFUL UPPER SYSTEMS IS MOVING THROUGH THE SOUTHWEST
UNITED STATES...AND WILL AFFECT PARTS OF TX AND THE LOWER MS VALLEY
DURING THIS FORECAST PERIOD. THE PRIMARY SYSTEM FOR FOCUSING THE
SEVERE THREAT IS A SUB-TROPICAL SHORTWAVE TROUGH MOVING ACROSS
NORTHERN MEXICO AND INTO SOUTHWEST TX. LIFT AHEAD OF THIS TROUGH
HAS RESULTED IN THE DEVELOPMENT OF A CLUSTER OF ELEVATED
THUNDERSTORMS OVER WEST TX NEAR LBB. INCREASING FORCING FOR ASCENT
AND TRANSPORT OF ELEVATED MOIST/UNSTABLE AIR NORTHWARD INTO REGION
WILL PROMOTE CONTINUED EXPANSION AND INTENSIFICATION OF THESE STORMS
THROUGH THE AFTERNOON. SUFFICIENT CAPE ALOFT AND STEEP LAPSE
RATES...COUPLED WITH STRONG DEEP LAYER SHEAR...SUGGEST A RISK OF A
FEW INTENSE UPDRAFTS CAPABLE OF LARGE HAIL. THIS THREAT WILL SPREAD
EASTWARD THROUGH THE DAY ACROSS SOUTHERN OK AND NORTH TX.

First snowfall of the season on the way? Perhaps. The image below is for Monday December 5th at 6AM. This would have 3 to 6 inches of snow over most of Oklahoma. 1-3 inches in the North. Around 6 inches along the Red River. What to take from this? The chance for accumulating snow is there, but amounts shouldn't be worried about right now. Let it get a couple days out to really start focusing on them. However, soil temps are still in the 50s. Snowfall rates would have to be decent to overcome melting.

Regardless, the outbreak of cold weather that has been mentioned...is on the way for December.

Hopefully it will materialize. Were I in charge of the weather, today would be the hottest it got between September 21 and April 15th, the sun would be reduced to about one day a month, then only in partial clouds, and the rest of the days divided up between sleet and heavy snow.

Bring it on.

It will be interesting to watch this system as it gets closer to Oklahoma. With the temps. forecast it could be a steady rain Sat. afternoon turning to a wet snow in some parts of Oklahoma that evening and overnight. Definitely a lot of interest with the big game in Stillwater where that could occur...it all depends on timing and how cold it will actually be. Cold rain appears to be a certainty though with the game beginning at 7 pm.

No your wrong.... Sure I wouldn’t like it but I also know that it has happened so infrequently that it would not be an event worthy of getting too upset about. After all it’s one of the more lopsided series in all of college sports. OU has held OSU scoreless more times than OSU has even beaten OU (not 100% sure but I believe this is 28 to 16). OSU has beaten OU 5 times in history in Stillwater.

I believe you're correct on OU shutting out OSU 28 times and I know you're correct on OSU only winning 16 times. I think that OSU has won 6 times in Stillwater but same difference; but this is the weather thread. LOL

WOW! On Wednesday I said: "Latest computer data still saying much to do about nothing for this weekend but boy are they teasing next week starting Monday!" Little did I know when I came into work today and glanced at the models that the NAM paints 14" of snow over OK on Monday! I need to look at more data before sounding the alarms. Would like to see other models agree. This is getting fun!

Andrew4OU
12-02-2011, 11:14 AM
Another update from AT:

WX UPDATE: Okay, I've looked over all the models. They all agree on many aspects. The main difference is that 2 of the 6 says heavy precip across central OK, the rest say the bullseye is across SE OK and N/NE TX. That difference means less snow/sleet totals in the metro or massive totals depending on which model is correct. As of now it looks like light wintry mix breaks out late Sunday afternoon, rain/sleet/snow then transitions to all snow Monday morning through afternoon before winding down. Winds may get up to around 50 mph. Could be a significant ice/sleet storm just SE of the I-44 corridor into SE OK if temps chill enough. Across central OK snow totals will depend on how much sleet is mixed in at the beginning. Several inches is definitely likely.
