Still have a shot at 1-2 winter weather chances over the next 15 days as we will get much colder air, but it does appear like it will be a sharp Arctic front that will set up near us so the positioning of the front will play a huge role on who sees the winter weather. 

 

Looking at the Thursday weeklies today, there may be a brief break in the cold after the 6th or so until it comes back on the 10th or so due to a ridge redeveloping over the NE Pacific into Alaska and into the Arctic once again and that looks to stick around until the 20th or so.

Was wondering if anyone found a year where the GOA ridge and associated warm pool lasted through summer. Would like to look at climatology on what happens in that situation when a weak El nino is present but I cannot find it. Sorry for asking for this and thanks for the help.

 

I haven't heard of any yet. Hopefully when JB and Joe D'aleo start looking towards spring and summer they will provide some analog years where that happened.

 

The 12z Euro is kind of 'meh' for snow chances coming up. Things aren't lining up how they were a few days ago. :(

Joe D'aleo took a look ahead at summer today (June-August). Finding the most similar years to the expected setup this year, he listed: 1953, 2013, 1957, 1993, 1967, 1963, 2002, 1979. The result around this area was near normal on temps, and normal to below normal on precip.

According to most of the years listed above, it looks like for Oklahoma at least, we will see equal chances of above/normal/and below normal temperatures with slightly below normal precipitation during particularly July and August with the most intense heat being centered during those 2 months. Good news there is we could likely see an early fall this year. :-) I know this is a winter forum so I'll quit doing summer stuff til after March starts now.

haha, it's fine. There's not a whole lot going on. It's going to get cold again and there looks to be a few chances for some light snow or frozen precip over the next 10 days according to the 00z Euro. At this time, it doesn't look like we'll see any 'big' systems.

00z Euro tonight still has a system on Feb 28th. This system might provide a light mix or light snow to parts of the area. Mainly in SW MO it looks like right now. 

 

Next Wintry type storm comes out March 2nd into March 3rd. Best chances will be in KS/MO.

Well, this time of year you can get winter and warm sunny weather in the same week. :)

 

12z Euro looks like the 12z GFS on the Feb 28th storm. This would be a light to moderate frozen precip event for East Central KS, into West Central MO, possibly reaching down to South Central MO. Looks like it would be too warm in NE OK, far NW AR and far SW MO but it would be close. 

 

The second system is farther north and would impact primarily central and northern Missouri with frozen precip on March 2nd.

 

Basically, the second system depends on what happens with the northern stream, mainly an upper low that wants to sit on the British Columbia/Alberta border just north of the US border. It depends on the strength, orientation, and location of this system to determine if we get more of the 12z Euro depiction (moderate event in central and northern MO), or the 12z GFS which was a pretty big ice storm for our area.

And today's 12z Euro looks to be coming in warmer with the Feb 28th (Friday) system, so most of the frozen weather should remain NE of our area.

 

The better chances for winter weather will come late on March 1st into March 2nd (Sat-Sun) when a system overruns cold Arctic air at the surface. This looks to be a bigger system.

Missouri may become the Show Me Ice state on Sunday - especially southern Missouri. Overruning is predicted over an arctic air mass. Notable qpf is also forecast in eastern OK and northwest AR, but perhaps fewer hours below freezing. Looks like the brunt of ice may be southern Missouri. Kansas (southeast) should see a lighter version.

Sounds like the concern is increasing for a potential significant ice storm somewhere in our area. 

 

From NWS Tulsa: 

 

EXTENDED MODELS IN OVERALL GOOD AGREEMENT THAT A VERY COLD ARCTIC
AIRMASS WILL IMPACT THE REGION OVER THE WEEKEND...AND LINGER WELL
INTO NEXT WEEK. SOURCE REGION FOR THIS AIRMASS IS CURRENTLY NEAR
THE NORTH POLE...SO NEEDLESS TO SAY...ITS COLD. SATURDAY WILL BE A
TRANSITION DAY...WITH LEADING EDGE OF COLDER AIR NUDGING INTO NE OK
DURING THE DAY...WHILE AREAS S OF THE FRONT SHOULD WARM NICELY. WILL
SEE A HUGE TEMPERATURE SPREAD...WITH 30S NEAR THE KS BORDER TO
AROUND 70 NEAR THE RED RIVER.

THE SHALLOW COLD AIR WILL CONTINUE TO SETTLE S SATURDAY NIGHT INTO
SUNDAY...WITH PERSISTENT SWLY FLOW ALOFT AND A DECENT 30-40KT H85
JET PROVIDING UPGLIDE ATOP THE COLD AIR. EXPECT TO SEE AN EXPANDING
AREA OF PRECIPITATION...PRIMARILY ALONG AND NORTH OF THE
FRONT...WITH THERMAL PROFILES SHOWING MOSTLY FREEZING RAIN AND SOME
SLEET ACROSS A GOOD PORTION OF NE OK AND NW AR. PRECIPITATION SHOULD
TRANSITION TO MOSTLY SLEET AND EVENTUALLY LIGHT SNOW LATER SUNDAY
INTO SUNDAY NIGHT BEFORE TAPERING OFF.

THIS WINTER EVENT IS STILL 3-4 DAYS AWAY AND MANY UNCERTAINTIES
PERSIST CONCERNING PRECIP TYPE AND PLACEMENT OF HEAVIEST PRECIP.
JUST BE AWARE THAT THE POTENTIAL EXISTS FOR SIGNIFICANT ICING ACROSS
PARTS OF NE OK/NW AR SATURDAY NIGHT INTO SUNDAY.

COLD AIR WILL LINGER WELL INTO NEXT WEEK...WITH TEMPERATURES RUNNING
MUCH BELOW NORMAL. WOULDN`T BE SURPRISED TO SEE A FEW RECORD "LOW
HIGH" TEMPS BROKEN SUNDAY AND MONDAY.

This could be a fairly bad ice storm for some of us, who though remains to be seen! Going to keep watching this one, going to be a longgg weekend. Not really looking forward to ice though, cant stand ice storms as I have had way too many bad things happen with them. Is beautiful yea but really dangerous. Good thing is most power and such is underground here for the most part, however the roads here....forget it! And with it being so hilly here if you dont have chains for tires your screwed cause the road departments rarely touch the side roads at all.
