Is anyone hearing about another pileup on I-44 near Miami, OK? My stepdad called and said it was very foggy there. Then all of a sudden the cars came to a standstill in front of him. A semi in front of him jackknifed trying to get stopped. The Oklahoma DOT website is useless and none of the Tulsa TV stations have nothing. Thanks!

Not seeing anything on local stations or google.

Also, nice pics Waterboy.

Will Rogers Turnpike is now closed again in far NE OK near Miami.

Via KOTV:

Part of the Will Rogers Turnpike, north of Miami, has been closed due to multiple accidents, The Oklahoma Highway Patrol announced.

Accidents range from mile marker 313 to 266 on westbound Interstate 44, and traffic has been diverted onto U.S. Highway 71 in Missouri.

Well, I don't know about you guys, but I'm ready for another snow storm!!!:popcorn: Pretty much because I really don't care for the flooding to begin or my shoes to get soaked walking to the car! It's nice to have snow cover it up.

You may be waiting awhile.

Insane pictures, Waterboy. That's more snow than I saw in my best nor'easter living on the east coast for almost a decade. :o

BTW, the Mesonet station at Nowata hit -31 F earlier, so that should be the new OK state record.

I wonder if they are trying to verify some of the readings. I heard some of the Mesonet stations went offline last night when the temperatures got so absurdly low. I guess some of the programmed algorithms thought the stations were reporting bogus numbers, when in actuality they weren't!

THE SPAVINAW DAM NWS CO-OP SITE MEASURED 27 INCHES OF SNOWFALL
WEDNESDAY FEBRUARY 9TH 2011 FOR A 24 HOUR PERIOD. PENDING
VERIFICATION BY NOAA`S NATIONAL CLIMATIC DATA CENTER...THAT SNOWFALL
TOTAL BREAKS THE PREVIOUS 24 HOUR OKLAHOMA STATE RECORD SNOWFALL OF
26 INCHES SET DURING THE MARCH 2009 BLIZZARD AT BOTH FREEDOM AND
WOODWARD.

RECORD LOW TEMPERATURES READINGS THIS MORNING FROM THE MESONET AND
OTHER SURFACE OBSERVATION SITES IN EASTERN OKLAHOMA AND NORTHWEST
ARKANSAS INCLUDE:

NOWATA OK -31
PRYOR OK -28
BARTLESVILLE OK -28
BLACKWELL OK -27
FAYETTEVILLE AR -18
TULSA OK -12
MCALESTER OK -4

Arkansas:

THE NATIONAL WEATHER SERVICE COOPERATIVE OBSERVER SITE NEAR
HUNTSVILLE ARKANSAS MEASURED 24 INCHES OF SNOWFALL ON 9 FEBRUARY
2011. PENDING VERIFICATION WITH THE NATIONAL CLIMATIC DATA
CENTER...THIS SNOWFALL WILL BREAK THE PREVIOUS GREATEST DAILY
SNOWFALL RECORD OF 18 INCHES SET ON 19 FEBRUARY 1921 IN BEE BRANCH ARKANSAS.

THE GREATEST 24 HOUR SNOWFALL RECORD STILL STANDS AT 25 INCHES SET
ON 22 JANUARY 1918 IN CORNING ARKANSAS.

I think Nowata's temp raised at least 50 degrees today from their overnight low.

Yep. Looks like the winner in that race was Marshall (N of OKC), with 31/-25 for a 56-degree spread.

Those types of diurnal swings are pretty common in the Panhandle, but probably close to a record for NE OK (strong frontal passages notwithstanding).

Great write-up on the once in a lifetime snowfall in NW AR on the 40/29 blog. Many questions raised:

1. Snow ratio in the band was not that high, under 15:1

2. Why did the band not move when the system around it did?

3. WTH re:the models? (2 big busts in a week for NW AR)

And yes the fringe element, as expected, is blaming this event on a military experiment, a plot by large companies, etc.

And the historic cold that followed yesterday made this a winter event off the charts for the 412 corridor. And equally amazing is that other parts of the area got a monster a week before.

The melt-off will be interesting. We are taking bets on the disappearance of the giant snow pile in the shopping center.

1. That was interesting about the snow ratios but not really surprising. Lots of forcing was in that band allowing good precip rates.

2. You've never had training thunderstorms? Similar situation, there was an elevated front that didn't move, moisture went up and over that front and produced snow in the same area.

3. It's always hard for the models to pinpoint mesoscale bands. The NAM was indicating there would be heavy snow in that area for days before the event occurred. It may have been a bit too far south but it was still showing it. The HRRR/RUC were indicating it as well but for the majority of the event, it was too far N with the band even as it was developing.

Was there lightning with the meso-band? This may have indicated the release of some CSI (conditional symmetric instability) or even upright instability. A similar situation in St. Louis happened in 1982, where only a few inches were predicted, but instead they received a narrow band of 20"+ due to CSI. With a good conveyor belt of moisture streaming in, this could have caused the convection to persist for a number of hours. The lower ratios certainly suggest that some warmer air was involved aloft than had been previously forecasted by the models. I've seen situations where narrow airstreams aloft are not well resolved, and result in some pretty large errors in the mesoscale, especially when a strong ageostrophic circulation sets up as a direct result.

No idea. As I was watching it develop, it developed into a pretty strong band. The band was 35-40 dbz at least and it stayed pretty much stationary throughout the entire event. It did move back and forth a bit by a few miles but it was mostly in the exact same place.

You can see it on: http://mesonet.agron...nt/mcview.phtml

From before Midnight on the 8th until at least 6 AM on the 9th using the Wichita radar site.

Temp has actually risen a few degrees here over the last few hours. I don't think we'll hit that overnight low of 31 since it's now 46.

Looks like the GFS and Euro are wanting to bring down some cooler air in the extended range and the Euro looks like it wants to set up the 850 MB 0 degree line near our area. Could be a battlezone between airmasses nearby with waves riding up along it.

I did not hear of any reports in AR, nor were there any in our area just on the fringe of the band.

Yeah, woke up to 42 degrees this morning. That is 54 degrees warmer than at this time a few days ago, lol.
