Rain Chances Increasing For The Weekend

From Chief Meteorologist Brandon Rector...

We once again had above average temperatures today despite a weak cold front moving through the area. Temperatures this afternoon were in the 70s which is about 10 degrees above average for this time of year.

Warm and windy conditions are expected to continue Thursday and Friday. Highs will be in the low to mid 70s. Winds should be from the south-southwest at 15 to 25 mph.

An upper level trough looks to build in the western U.S. this weekend. We should see some upper level disturbances move through the region Saturday night through Wednesday morning. An upper level low should build in the middle of the trough. It will move slowly towards us early next week and not completely pass by the Big Country until late Wednesday. With a cold front also expected on Sunday, there will be several lifting mechanisms this weekend and the first half of next week. Moisture should be in place so the chance for precipitation is looking better. The chances begin Saturday night at 20% and then increase to 40% for Sunday through Tuesday. There is a slight chance of lingering activity early Wednesday. Highs during this time period will start in the low 70s on Saturday, fall to the low 60s on Sunday and fall even further to the low to mid 50s for the first half of next week.

The strength and track of the trough as well as how cold the air is behind the front are something we are keeping a close eye on right now. These are all factors that will play a big part in how much precipitation we see and how cold it gets. Stay tuned for further weather updates.

Have a terrific Thursday!
