Cloud cover will increase this afternoon and evening as upper level lift increases due to an approaching disturbance. The temperature profile in the lowest few thousand feet, near and just above the surface, continue to feature cool temperatures. Warm air advection above that cool layer will support increasing precipitation chances beginning late tonight. The Simulated Radar from the HRRR model looks wet for tonight but looks can be deceiving. A layer of dry air near and just above the surface should cause most precipitation to evaporate before reaching the ground. The same weather model indicates no rain accumulations through midnight even though rain will be falling. Very light rain or sprinkles will be possible this evening across South Texas, Deep South Texas, the Coastal Plains, and Southeast Texas. We’ll see rain increase on Saturday across Deep South Texas and the Rio Grande Valley but the current forecast has that taking place after tonight’s festivities.

Temperatures late this evening and around midnight will be in the 20s across the Texas Panhandle. 30s are across the Permian Basin, West Texas, Northwest Texas, into the Big Country. The D/FW Metroplex up to Texoma and Northeast Texas will drop off into the low 40s by midnight. Central Texas, East Texas, and the Brazos Valley will be in the upper 40s. San Antonio, Houston, Southeast Texas, the Coastal Plains, South Texas, Deep South Texas, and the Rio Grande Valley will be in the lower 50s by midnight. Winds will generally be light and under 10 MPH but it’ll still make it feel cold out there.
