Bring on the cold?

Wait, bring on the cold? Really? Yes, this is still Gary McManus, follicularly- challenged Master of all Time and Space* (*powers limited to eating Pop-Tarts with nothing to drink...try it, you'll see it's pretty tough)? Well, yeah...the way I see it, nothing too bad happens when it's 42 degrees outside. Well, other than having to wear extra clothes. Layers (shudder), even.
But isn't the cold weather a darned sight better than what we saw Friday, when the threats of high-end severe weather came to fruition and dropped up to 3 twisters on extreme SE OK (and over a dozen across the ArkLaTex)?

The biggie for us, of course, was the strong tornado that hit Idabel, injuring 30 and killing 1 person. The tornado traveled extremely close to our Idabel Mesonet site, becoming the fifth Mesonet site directly impacted by a tornado, joining El Reno (5/24/2011), Tipton (11/7/2011), Fort Cobb (11/7/2011), and Inola (8/9/2018). The 108 mph wind gust would also be the highest since the 151 mph gust during the May 24, 2011, El Reno strike by an EF-5 twister.

Apparently the gust was from Rear Flank Downdraft according to NWS Shreveport meteorologists surveying the damage path:
"AFTER CROSSING THE RED RIVER AND ENTERING MCCURTAIN COUNTY, OKLAHOMA, THE TORNADO PRODUCED AT LEAST EF-2 DAMAGE, RIPPING THE ROOFS OFF SEVERAL SINGLE FAMILY HOMES. BEFORE REACHING IDABEL, THE TORNADO MISSED THE OKLAHOMA MESONET IDABEL OBSERVING PLATFORM BY APPROXIMATELY 150 YARDS. AT THE PLATFORM, A MEASURED GUST OF 108 MPH WAS RECORDED BY THE 10M ANEMOMETER AND BASED ON THE DAMAGE PATTERN OF THE GRASS IN THE AREA, IT WAS DETERMINED THAT THIS GUST WAS FROM THE REAR FLANK DOWNDRAFT OF THE SUPERCELL THUNDERSTORM."
The 108 mph gust ranks as the fifth highest wind gust since Mesonet wind measurements began in 1994.

#s 1 and 2 came from the EF-5 that hit El Reno, but the two Lahoma wind gusts were from straight-ling winds. At any rate, being on this list is not an honor.
We did get some beneficial rainfall, and as we know being Okies, you often have to take the good (moisture) with the bad (severe weather) around these parts.

So as we go through our next few days of deliciously warm weather, we await our next cold front on Thursday which will usher in nearly a week of below normal temperatures, which at times will feel like December, which is just a few weeks away anyway. Might as well visit it early.

Expect lots of highs in the 40s and 50s and lows in the 20s and 30s.

Snow? Yeah, I heard you thinking that (okay, my ONE other power besides the Pop-Tarts deal) maybe we will see our first snowfall in the state during this period. Well, don't bother...that first snow already happened overnight Friday in the Panhandle.

The chances for moisture we DO have over the next few days are expected to be on the light side.

So break out that winter coat...dust off the sweaters...then go buy something to store your sweaters in--they shouldn't be getting dusty.
