We’ll see quite a temperature variance today with a weak cold front stalled across north Texas.  Highs behind the front today will range from the upper 60s to upper 70s.  Ahead of the front, folks will have one more day of abnormally high readings in the 80s and low 90s before a stronger cold front arrives on Tuesday.  This next front will surge south during the day on Tuesday reaching the upper coast late Tuesday night into early Wednesday morning and the Rio Grande valley region by mid-day on Wednesday.  Rain chances increase behind the front for Wednesday…particularly across central, north central and eastern Texas Wednesday through Wednesday night.  Rainfall amounts will not be significant, but every little bit helps.  Severe weather is not expected.  The rest of the work week looks dry with generally less humid air in place.  Overnight lows will be chilly for all but south Texas residents, and daytime highs will be pleasant and more fall-like.
