The potential for very heavy rainfall and flooding will increase across all of North and Central Texas Monday through Wednesday. A slow moving upper low will combine with a slow-moving cold frontal boundary and copious moisture to produce several days of rain and thunderstorms. Many areas will see two to four inches of rain with heavier amounts possible.
A weak cold front will move southeast toward the I-20 corridor today before becoming stationary this evening. It will be partly sunny and warm with skies becoming mostly sunny along and west of I-35 this afternoon. Highs will be in the 80s. Winds will be southwesterly at 10 to 20 mph and become northwest and north at around 10 mph behind the front.
A front will become stationary near the I-20 corridor this evening and then lift back toward the Red River before daybreak Sunday. There will be a slight chance of showers and thunderstorms overnight north of a Graham to Canton line. Lows will be in the upper 50s near the Red River and in the 60s elsewhere. Winds will be east to northeast at 5 to 10 mph to the north of the front and southeast around 10 mph to the south of the front.
Isolated thunderstorms are possible Sunday afternoon and evening across western portions of the forecast area as a dryline approaches. Storm coverage should remain low, but any storm that develops has a chance of becoming severe with large hail and damaging winds. Activity will continue into the evening, but the severe threat will decrease after 9-10 PM as instability wanes.
We will have a SKYWARN Basic Class on Saturday, March 24th in Rockwall (Rockwall County). The class will be from 11 am to 1 pm. Classes are free and registration is not required! We hope to see you there!
