Heavy rain, gusting winds, possible storms in forecast

HUNTSVILLE – A low pressure system moving into the state today could produce severe storms, particularly in areas west of I-65.

But it’s heavy rains and high winds that are most concerning as the weather moves eastward through the Tennessee Valley.

“There is a low chance for strong to severe storms this evening into Tuesday morning,” the National Weather Service Huntsville office said this morning. “These will bring threats of gusty to damaging winds, a tornado or two, and locally heavy rainfall.

“Wind gusts of 40-50 mph are expected through daybreak Tuesday.”

The office is predicting heavy rain today and Tuesday with up to three inches possible in some places across the Tennessee Valley.

“Very heavy rainfall will also accompany the system as it traverses the region,” the office said. “Rainfall totals of 1 to three inches are forecast. Very heavy amounts of rainfall in a short time can run off and produce flash flooding.”

This is a increased chance of a flood threat if the “storms train (move over the same area repeatedly),” the weather service said. “This will be especially dangerous in the evening/overnight when flooded roads are difficult to see.”

What the NWS calls “breezy’’ conditions with a chance of showers are forecast for Tuesday. There’s a slight chance of rain Tuesday night. Wednesday will be partly sunny as will Thanksgiving Day. The chance of showers returns by nightfall.
