For much of January, we had a dry winter weather pattern with sunny, mild days and clear, very cold nights. This was the result of a north to northwesterly flow aloft, which tends to bring cold and dry high pressure south from Canada. We had several arctic visits, but just caught the fringes of the very cold stuff each time.
A similar upper flow seems to be taking shape for later this week and perhaps into next week. It will favor cold nights (below freezing) but fairly mild days, and sunny conditions.
About this time every year, I get asked when the last spring freeze might take place. The (30-year) average dates for last freeze in Texoma are mid-March…so we’ve got a ways to go yet.
Of course, we’ve seen freezes into early April several times in the past five years, so patience might be the best course here.
