After a warm-up today and especially on Tuesday, Houston will return to cold weather this week with highs mostly in the 50s. We should also see a fair amount of sunny skies—barring a gray and warm Tuesday. The forecast for the weekend is not year clear, alas.
Martin Luther King Jr. Day
Chilly conditions this morning, generally in the 30s, will warm up fairly quickly as the sun comes out. It should be a pleasant day to watch a parade, or otherwise partake in outdoor activities, as temperatures rise into the low to mid-60s under partly sunny skies. Winds will shift to the southeast later today, which will bring some more clouds into the mix this afternoon. Lows Monday night will only fall into the 50s with the modified air.

Tuesday
This will be a warm, and possibly wet day as a southerly flow establishes itself over the Houston area. Skies should be mostly cloudy in response to the increased moisture, but even so high temperatures should get up to 70 degrees. Rain chances will increase Tuesday afternoon, and especially Tuesday night ahead of a cold front. I don’t anticipate this front will produce the intense showers and (especially) thunderstorms that we experienced early Saturday, but most of Houston should still see about one-half inch of rain.
