January '10 Weather Discussion

[OKCisOK4me]

lol, The Stillwater Regional Airport is reporting something I've never seen before-- "unknown precipitation". They're at freezing 32, so I guess they can't determine if what's coming down is freezing or not.

Maybe it's meatballs!

Area weather update

...warning decision update...

This warning decision update concerns central and southwest oklahoma.

Fast animations of kfdr reflectivity data and storm relative
velocity suggest a mesoscale convective vorticity maxima was
forming about 50 miles south of wichita falls. This circulation was
associated with the northern extent of the convective line that
extends into central texas.

If this evolution continues it will help to enhance vertical motion
and precipitation rates from southwest oklahoma into then into
central oklahoma over the next few hours. The result would be an
increase in glazing rates.

For those checking out the live blog at Live Severe Weather Coverage Dis ...
I'm going to leave it unmoderated but I have just about every twitter feed possible tied into it. So a lot of the updates and such from local EMs will go in there.

[westsidesooner]

Some very good news....at least for now the precip in Bethany has switched over to heavy sleet.

[venture]

Much more sleet here in East Norman now.

[rod4soonrs]

does this mean change to snow will be sooner rather than later? Locals say after 10, but seems if there's sleet, the upper levels are cooling quicker.

[PennyQuilts]

Just got in from putting out extra feed for the birds. It is LOUD, out there - sleet here, too. Too bitter to stay out long.

[venture]

I really don't expect to see snow in the Metro, except maybe far NW, until tomorrow with the wrap around.

[blangtang]

pretty much all sleet now in central norman by campus. hope it stays that way!

[OKCMallen]

Pretty much only sleet for the past 45 min or so at 50th and Western.

[venture]

Yup same down here. New GFS is coming in now, will see if it says the same story for tomorrow.

Edit: GFS isn't biting on the redevelopment of snow under the upper low. Maybe just light snow/flurries through noon and that's it.

[Bostonfan]

Morgan saying 5-8 in of snow for metro, moderate to heavy snow tomorrow. What's this guy looking at?

[rod4soonrs]

Gary says possible to see very heavy accumulations of snow in the okc metro after midnight through tom. night or sat. morning

[venture]

18Z NAM just show the chance for a good 3-6" of snow tomorrow, but 18Z GFS has us dry.

[sacolton]

I imagine everything will stay shut down until next week.

[jstanthrnme]

Well, here comes a dry slot it looks like. Though once the precip comes back, will it be snow, sleet, or freezing rain?

[PennyQuilts]

We've been back to ice for the last hour and a half, for the most part. Every once in awhile I hear sleet hit but it is mainly icy rain. The trees are starting to show the strain.

[venture]

Remained mostly sleet here since the first change over. Dry slot should be through the metro in the next hour. Freezing Drizzle will probably occur for a bit this evening.

[venture]

Sun is peaking through in Norman, but winds are up a bit.

[PennyQuilts]

Am I seeing bright lightening out there????? (no thunder). It is 6:07 and has been going on for about 10 minutes.

[Bunty]

Here are some storm reports from WFO Norman, OK (OUN) from the IEMBOT RSS feed for the last 12 hours. Here is the link IEMBOT Feed

[blangtang]

power flashed 4 times but came back within 30 seconds each time.

Theres a very impressive view of the much discussed dry slot on wv satelite imaegry for those of you who are interested. The main upper low is still back west of El Paso Texas. This is time sensitive so it'll change as time goes by. When you go to this link click on:

1 Loop Duration:
2 and click on 12 hours,
3 then click the "water Vapor" option on the left center of the page, then click the
4 "Large size option" above the map and then click on the
5 map itself.

Sorry I'd save it and post the animation but I don;t know how :-(

Venture, latest indication show the dry slot will be short lived with what is coming out of the SW. Your thoughts? How much snow from these overnight before the final wave tomorrow? I say we're gonna have more decent precipitation overnight and tomorrow.

thanks for the link. Pretty impressive dry slot. One thing I noticed is how slow this system is moving.
