Don’t put away your winter coats yet, there’s a good chance the coldest air so far this winter could reach Central Texas next week. Wednesday’s forecast solutions call for a large trough of low pressure in the middle and upper atmosphere to develop from central Canada into the southern Plains states during the early and middle parts of next week. This trough will allow very cold air to spill south into Texas beginning sometime next Tuesday or Tuesday night, with the cold air persisting across through next weekend.
Although there is still some uncertainty in the magnitude of the cold air, forecasts call for high temperatures next Wednesday through Friday to remain in the 40s to low 50s. Lows temperatures are predicted to be in the 20s and 30s. Most locations should expect at least a couple of nights with freezing temperatures.
Long-range forecasts indicate light precipitation may develop sometime late next week as weak overrunning pattern sets up. We will need to monitor this closely as the intersection of the moisture and cold air could potentially produce some wintery precipitation.
Stay tuned over the next few days as the details become clearer on this upcoming cold pattern. And be prepared for some additional freezes.
