Chris Coleman, ERCOT Senior Meteorologist

Updated Friday, March 27

General Discussion: One more relatively hot day today before a cold front moves through, resulting in a cooler weekend. That said, this weekend’s temperatures will still be above normal for late-March – just not to the extreme levels experienced the past few days. Next week shows more potential for above-normal temperatures, but a couple more fronts will prevent any heat build. Temperatures next week will be more commonly in the 70s and 80s, as opposed to the 80s and 90s of this week. Also, the frequent fronts will limit the humidity on most days. There will be an increase in rain chances over the next several days, including this weekend in spots. North Central and Northeast Texas will have the best opportunity for significant rainfall. West Texas will have less rain chance.

Today: Much more cloud cover is expected across ERCOT today – especially for West Texas. West Texas locations will fall well shy of yesterday’s highs, but mid-80s will still be common. Dallas-Fort Worth is also likely to have too much cloud impact to match yesterday’s high of 86. South Central, South, Coast, and East zones have better opportunities to see highs today similar to yesterday, although it’s unlikely the Valley will see the 100-degree highs that some locations experienced yesterday. Houston has the best chance of the large cities to match or even slightly top yesterday’s high of 88. Some scattered showers and thunderstorms will develop well after midnight tonight in the vicinity of I-35.

This Weekend: Scattered showers and thunderstorms across the North, North Central, and South Central zones on Saturday morning. This will not be widespread nor heavy, and some locations will not get any rain out of this. This scattered precipitation will be associated with a weak cold front, moving into East Texas, Coast, and South Texas Saturday afternoon. Clearing skies and lower humidity will move in behind the front. Some of the rain will linger into Sunday in South Texas, which may build northward into parts of Central Texas and the Gulf Coast. Again, this precipitation will be mostly light and scattered. A more significant rain event will move across North Texas on Monday. Temperatures this weekend will be noticeably cooler, especially in the nighttime and morning hours.
