Temperatures are mild this morning, in the 50s for most of the Houston area, but a surge of colder air will move in tomorrow.
A weak cold front is sagging into southeast Texas (temperatures are in the 40s in Brenham with low humidity), and will stall along the coast later today. This could provide the impetus for some scattered showers this afternoon, but I’m not expecting much rain. Highs will be in the upper 60s.
A stronger front and upper-level low pressure system will move through Houston on Thursday. Before then highs should reach about 70 degrees. Although we can’t rule out the possibility of a few thunderstorms, right now the best dynamics for severe weather remain to the east, over Louisiana. Winds will pick up out of the north on Thursday afternoon as the front moves through, ending rain chances and likely clearing skies by sunset. Expect a breezy evening and cold night.
Temperatures will fall to about 40 degrees by Friday morning, and expect continued gusty northern winds as cold air dives down across the Rockies and midwestern United States into Texas. Highs will likely only be in the mid-50s under mostly sunny skies.
This will be a cold morning. Houston has a chance to see its second freeze of the season, although I expect most of central and southern portions of the metro area to remain just above freezing.
