Expect much more typical weather for February this week compared to the spring-like beginnings of the month last week. Texomas’ first three days of February 2012 were unseasonably warm, and Friday the 3rd also saw severe storms march across along the Red River with hail to egg size around the Sherman-Denison. All of that has changed, as a dry northerly flow and a series of cold fronts should keep the numbers in a more typical range for mid-to-late winter.
The map shows a northerly wind flow aloft. This is steering cool air southward from Canada, a big change from recent weeks:
The good news: we're on the back edge of this circulation, so extreme cold should remain to our east.
Another factor: The snowpack to our north is very spotty with snow over much of Nebraska, but almost none over South Dakota or over Oklahoma and southern Kansas. The generally sparse snowcover allows the chilly Canadian air to warm more than it would when moving over snowy ground. This is expected to further limit the intensity of the cold here.
So we should remain within a pattern of fairly cold nights and cool-ish days into the weekend, but no severe cold is expected for Texoma.
