Chris Coleman, ERCOT Senior Meteorologist
Updated Tuesday, April 23
General Discussion: Attention has turned to a slow-moving area of low pressure, which is bringing another round of severe weather and significant rainfall totals to a large swath of ERCOT through Thursday morning. Portions of the West, North Central, and South Central zones are most prone to high rainfall totals and flash flooding. The clouds and rain will hold down temperatures today and tomorrow, then begin to rebound warmer on Thursday. Temperatures will trend back above normal on the weekend -- with plenty of sunshine and dry weather anticipated.
Today: Mostly cloudy skies. Showers and thunderstorms over much of West Texas, increasing as the day progresses. Abilene, Midland, San Angelo south to Big Bend all are areas of concern for strong to severe thunderstorms (large hail, damaging wind) and flash flooding. Also will see some storms reach the Hill Country and D/FW Metroplex late in the day into evening. Expect the rain and thunderstorms to continue overnight tonight -- especially North Central and West zones. Temperatures this afternoon will be a couple degrees cooler than yesterday, on average, due especially to extensive cloud cover. Highs mostly in the 70s -- though some 60s Northwest and 80s South and Coast.
Tomorrow: Showers and thunderstorms will be increasing over the South Central zone, while continuing North Central and West. Look for the area of precipitation to spread into South, East, and Coast Wednesday evening. Cooler again tomorrow.
