On-and-Off Rain and Storms Possible Saturday and Sunday

Thursday and Friday both brought periods of rain and storms for the Tennessee Valley, but once again not everyone received a good soaking. Huntsville only recorded .16 inches of rain this past week, putting the total for the month of August at a mere .67 inches. If your grass is starting to feel crunchy too, you still have a chance at getting rain over the weekend.

Warm and humid air continues to flow in from the southwest Saturday and Sunday supporting widely scattered storms each day. Isolated showers are possible all day long, but the best chance of storms will come after noon through sunset. Some storms could get strong with heavy downpours, gusty winds, and lightning possible.

We don’t expect a wash-out either day this weekend, so you don’t have to cancel your plans. You should still be prepared to head in at any point should a storm develop nearby though. Track heavy storms with WHNT.com’s Interactive Radar or swipe over to the radar feature on Live Alert 19!

Outside of storms, it’s warm and humid this weekend with highs in the mid to upper 80s Saturday and Sunday. We’ll get patchy fog each morning and partly to mostly cloudy skies each afternoon.

More storms, then it’s dry! Monday and Tuesday bring more of the same: partly sunny, hot, humid and a chance of some scattered, locally-heavy thunderstorms. The chance of rain is highest just ahead of a cold front Tuesday, but it dries out and gets more comfortable behind that front!

Daytime highs fall as low as the upper 70s in the higher terrain by Wednesday; most of the Huntsville-Decatur-Shoals area stays in the 80ºF to 85ºF range with low humidity, a fresh north wind, and a mostly sunny sky.

Our brief cool down takes low temperatures as low as the middle-to-upper 50s in the usual ‘cold spots’ by next Thursday morning!
Before you think summer is over, there is definitely some more hot weather coming! Temperatures recover to near or slightly above average by the end of next week.
