Chris Coleman, ERCOT Senior Meteorologist

Updated Tuesday, December 10

General Discussion: A cold front finished passing through ERCOT this morning, resulting in the coldest day thus far this month. Clearing and colder tomorrow morning, then trending warmer between Wednesday afternoon and Friday. Friday’s temperatures will likely be back above normal across the state. A weak front may move through on the weekend, which could result in a bit of cooling, but impact is likely either minimal or very regionalized. Another cold front is due to move through next Monday. That front may be similar to this front with a chance of colder temperatures. The atmosphere across the Northern Hemisphere is still lacking support for extreme cold; however, prolonged periods of above-normal temperatures are also not supported.

Today: A large area of rain and a few embedded thunderstorms will appear this morning across all but Far West and most of South Texas. This rain will become more scattered and lighter in intensity this afternoon, then wind down quickly during the evening hours. The clouds and precipitation will hold down temperatures in ERCOT today. Most locations already recorded their high for today at or before daybreak. Temperatures this afternoon will be mostly in the 40s (some 50s in South Texas). The mid-afternoon temperature between Dallas and Austin will be in the 40 -45 degree range. The afternoon temperature will be only slightly less chilly in Houston with mid-to-upper-40s likely. Clearing skies in West Texas with highs also mostly in the 40s. Colder tonight, especially where the clouds clear and wind is light. Not expecting any widespread freezes tonight into tomorrow morning, but most locations away from South Texas will fall into the 30s overnight tonight.

Tomorrow: Some lingering clouds in South Texas early. Otherwise, much more sunshine across Texas and dry weather for Wednesday. After a chilly start to the day, temperatures will rise to mostly the middle 50s to lower 60s.
