A large cool airmass from Canada will bring the coolest nighttime temperatures so far this season tonight and Saturday night. Warmer southerly winds will begin a warming trend Sunday afternoon. A weak front from the north will stall near our area Tuesday. A weak wave in the upper level wind flow may produce enough lifting motion for a few showers to develop near the front, giving us a shower chance Tuesday. Tropical air will begin to expand north through south Texas by late week.
I'm expecting clear and chilly tonight and Saturday night, lows each night in the low to mid 40's. Sunny with low humidity Saturday and Sunday, highs in the mid to high 60's Saturday, the low to mid 70's Sunday. Sunny Monday, high in the mid 80's. Partly cloudy with a chance of a shower Tuesday, high in the 70's. Partly to mostly sunny Wednesday through Friday, highs in the 80's, near 90 Friday.
