One more nice day!

Rinse and repeat weather to start our weekend then an Arctic intrusion has it's eyes set on Texoma Sunday into Monday.

Just like today, we're forecasting a big spread of temperatures across Texoma tomorrow. A weak cool front is "washing out" (wouldn't it be nice if that meant rain?) right over us so expect slightly cooler temperatures north around Chickasha to Elk City, 70s in Duncan, Lawton, Altus, Frederick, Walters, and Waurika and upper 70s to low 80s across north Texas.

Saturday's High Temperatures

We're still tracking that wintry blast for Sunday and you can scroll down to see my thoughts from yesterday concerning the wintry weather. Not much has changed in the forecast aside from highs trending colder for Sunday. Expect upper 20s for most of Texoma with a gusty northeast wind. In fact, wind chills will range from the single digits to teens both Sunday and Monday.

I'll be enjoying a relaxing Friday night after work away from the computer and tv for the most part so have a good one! Expect another update sometime tomorrow.

Light Wintry Mix Possible Sunday...

Although our Friday will feature sunshine and mild temperatures in the 70s, Old Man Winter will come back strong towards the second half of the weekend.  

Here are some of the ingredients:

Shallow cold air arrives Saturday night as shown above.

 

Upper level energy (red box) arrives Sunday (left image) and a light mix breaks out over parts of Texoma. NAM forecast precipitation types are shown on the right and indicate a mix of light rain, or sleet but with temperatures near freezing, this would likely be a mix of light freezing rain, drizzle, & sleet. 

NAM forecast 500 mb vorticity valid 1PM Sunday (left) & NAM forecast precip. type (right).

*Timing: Light wintry mix of freezing rain, drizzle, & sleet develops in the morning, ending by mid to late afternoon. Low impacts expected but still could be some icy spots on elevated surfaces. 

 

Why are we thinking freezing rain and sleet as opposed to snow? The details lie in our forecast sounding shown below. This is a forecast showing us what the temperatures are as we get higher up in the sky. The space in the blue box shows very shallow but below freezing air settling in close to the ground BUT as you get higher in the sky, the air warms up considerably. This means that as rain drops form high up in the sky, they will melt in the warm layer but then either freeze on contact (freezing rain/drizzle) or refreeze into sleet pellets.

Friday warm-up but it comes with a price: very high to extreme fire danger.

Cold air retreats to our northeast on Friday, allowing southwest winds to return to Texoma. 850 mb temperatures surge to around +10 to +16° C and with plenty of sunshine, highs will easily reach the 70s. However, the fire danger will become a concern in the afternoon as relative humidity values fall to between 10-25% and south winds shift to the west throughout the day. Max wind speeds of 15-25 mph with gusts to 30 mph are possible. 

Welcome to Meteorologist Matt DiPirro's Blog!

Welcome to my blog!

This is the first official post on this new blog. The focus will be mostly weather-related but do expect me to share some personal reflections or opinions. Please see the disclaimer at the bottom. I have been a meteorologist at KSWO-TV in Lawton, OK since August of 2011, so around two and a half years, and boy does time go by fast. Recently, I have gotten into the hobby of photography so you may see many posts and eventually some slideshows of my work.
