Warmer now through Friday, before another cold front this weekend

It’s chilly again this morning — generally in the upper 30s across the Houston metro area. After another cold start to today we’ll warm up until this weekend.

TODAY and WEDNESDAY

Both days should bring mostly sunny skies, with highs in the low 60s. Temperatures tonight will fall to around 40 degrees, and as clouds return on Wednesday night temperatures will only drop into the low 50s.

THURSDAY

Increasing clouds on Wednesday night and Thursday morning will herald the return of higher moisture levels, and an upper-level disturbance will move overhead the area later on Thursday. Still, conditions for severe storms aren’t good, and much of the region should only see only modest accumulations of rain. Chances are best along the coast.

FRIDAY

Temperatures will rise into the upper 60s on Friday under mostly sunny skies before a cold front moves through. This will bring some cooler, drier air, and drive lows back into the 40s.

SATURDAY

Like last weekend, we’ll see continued cold air advection on Saturday, keeping highs to about 60 degrees. A fast moving disturbance could bring some rain from Saturday afternoon through about midnight, but accumulations shouldn’t be significant.

SUNDAY

I’ve been forecasting conditions for the Houston Marathon for more than a week, and they look pretty much the same. Temperatures on the start line will be cold, about 40 degrees give or take a few, and it’s very likely that any overnight rain will have ended. Temperatures by the end of the run should warm up to around 50 degrees. With the probability of light winds, conditions for long-distance running look exceptional.

As a first time runner, I’m taking credit.
