Slight risk of severe storms tonight
A few showers are possible this morning, but most of the rainfall will hold off until later this afternoon.
Storms will begin after about 5 or 6 pm and be very hit-and-miss, which means not all of us will accumulate rain.
That being said… Severe threat is marginal to light across the area. The risk for severe weather is highest over the hill country, and rainfall chances there are also looking the most promising.
We’ll repeat today’s conditions again tomorrow ahead of an incoming cold front Saturday night.
This cold front Saturday will supply us with the moisture and instability we need to see somewhat more widespread rain.
The severe threat stays marginal to start the weekend, a good chunk of our rainfall will take place late Saturday through Sunday morning.
Total rainfall accumulation still looks to be anywhere from 1” to 2.5” by the end of the weekend, but because it will be spread out over the next few days, flooding threat is looking pretty low.
The National Weather Service has released a statement about the severe weather threat for central Texas both today and tomorrow.
