FROM THE NATIONAL WEATHER SERVICE:
Area of Concern:
Areas along and west of the I-35 Corridor
Threats & Impacts:
Tornadoes: A brief, isolated tornado is possible
Winds: 60-70 MPH gusts possible
Hail: Quarter size hail
Rainfall: Up to 1 inch possible. Minor flooding is not expected, but ponding of water from brief heavy rain may create traffic hazards.
Expected Thunderstorm Timing:
Rio Grande/Edwards Plateau: 11PM Tue - 4AM Wed (greatest severe weather potential)
I-35 Corridor: 4AM-9AM Wed
East of I-35 and I-37: 9AM-1PM Wed
A storm system moving across the Southern Plains will result in showers and thunderstorms along a cold front Tuesday night. This line of thunderstorms is expected to develop across West Texas/the Rio Grande Tuesday evening and quickly move east Tuesday night. Large hail and damaging winds are possible with the line, along with a brief tornado. The tornado threat may increase if isolated cells are able to develop ahead of the main thunderstorm line Tuesday night. Brief heavy rainfall will also be possible during this time, but the speed of the system should keep overall flooding concerns low. Rain will quickly end from west to east behind the front Wednesday morning.
Additionally, strong and gusty non-thunderstorm winds will be possible across the region both ahead of and behind the front on Tuesday and Wednesday with gusts up to 35 MPH possible.
