Late-Season Cold Front

There is relief on the way! A strong, late-season cold front will move through North Texas by midday, Central Texas this evening and South Texas late tonight/early Tuesday morning.

There will be a chance for strong to severe storms as the front passes, although the overall severe weather risk is low at this time. Sixty mph winds and small hail can expected with some of the stronger storms.

They may also be heavy downpours, too. The atmosphere is very saturated which supports heavy rainfall events.

Short-range models suggest parts of the state could collect more than a 1/2" of rain over the next 48 hours with locally higher totals. 

Once the front is through the state, clouds will hang tight Tuesday and that will help keep temperatures cooler. Many locations will drop by 10°F or more Tuesday compared to Monday.

The relief Tuesday is short-lived. By Wednesday, forecast highs are back into the 90s and most of the state will be back in the upper 90s close to 100F by the end of the week.
