Snow; Milder; More Arctic Air: Active 7-Day Period

It's going to be a wild ride during the next seven days in our world of weather.

Look for a chance of light snow Friday as a mid-level low moves overhead. This low contains very cold air aloft, which normally would favor heavy precipitation. A lack of moisture offsets this to create a scenario where we might receive light accumulations of an inch (probably less):

The system will pass to our east. Westerly winds and sunshine will boost highs into the 40s and 50s over the weekend, but more cold air lurks in our 7-Day Forecast.

Three of the most reliable computer models have agreed since last Sunday on the evolution of another arctic air mass over the next few days. A strong mid-level ridge over the Gulf of Alaska will allow frigid air to re-load over northern Canada, and then slide southward underneath a pronounced north-south steering flow. This is similar to what happened this past Monday, but the air doesn’t look to be as cold.















                                               Mid-level (500mb) flow for 6am Monday / GFS model


So what does this mean for Texoma weather?  Temperatures will return to lows in the 20s (possibly teens) early next week, but daytime highs will not be nearly as cold. It will be windy and very wintry though.

Limited moisture has my snow chance for Mon-Tue at only 30%, but this figure will no doubt need adjustment up or down as the system takes shape.

 Take Care,

    Thanks for your updates! Please remind all to put out extra feed for the birds during this long period of cold. They need it to survive. I've seen a few dogs out during this also..please, provide shelter for your animals!

    The entire week seems very interesting with several waves of energy moving through our area, with some more significant than others. Looks like the possibility for another significant event the middle of next week.
