Tennessee Valley Forecast

From WHNT News 19 Chief Meteorologist Jason Simpson - Wednesday, February 22, 2012 - Update at 9:25 PM

Round One Over

More Storms Thursday Evening

Cooler & Drier Starting Friday

Meteorologist Jason Simpson's Forecast:

Round one is over, and now we are waiting for round two. Heavy storms produced hail and gusty winds along with frequent lightning in North Alabama and Southern Tennessee on Wednesday evening, but the threat of strong and severe storms has ended for now. Patchy dense fog will develop through the rest of the night, and visibility early in the morning could be very poor in spots that got heavy rain with the evening storms. We expect a partly to mostly cloudy sky overnight and into Thursday morning. Some sunshine during the day on Thursday should allow for the warmest day of the year so far with highs in the lower 70s. The warm, humid air surging in from the south may kick off a few isolated showers here and there on Thursday, but the main window of opportunity for the next round of storms is from sunset to about 3 AM Friday. By the way, that warm air will be riding a gusty southwest wind averaging 15-30 miles per hour, so hold on to your hat tomorrow!

The storms on Thursday evening and early Friday morning should look a lot like the ones we had on Wednesday evening. The most likely scenario is for a band (or "line") of storms developing over West Tennessee and North Mississippi in the middle of the afternoon. Those storms will move into Shoals between 6 and 9 PM. They'll get to Fayetteville, Huntsville, Decatur, and Cullman between 9 and midnight, then they should pass through Scottsboro, Fort Payne, and Albertville between midnight and 3 AM. These times are subject to change as they are a rough estimate. The timing will be a little more accurate once storms actually form tomorrow.

The main threat tomorrow night will be from damaging winds and large hail; however, the chance of a tornado is not zero percent. We believe the tornado threat is very low, but even in the least-likely environments, they can occasionally develop. We cannot know with certainty if a tornado will affect any one particular community, but I can say that the threat is very, very low. If a warning is issued, we will be here to keep you informed on TV, online at whnt.com, and on Facebook and Twitter.

By Friday afternoon, cooler air will blow in from the northwest. Temperatures will drop from near 60 in the morning to around 50 by mid-afternoon. The weekend is looking cooler and drier; highs will be in the lower 50s on Saturday and near 60 on Sunday. Expect morning lows over the weekend to be in the lower 30s; that's cold enough for some frost over most of the Valley.

Tonight: Patchy fog. Partly cloudy. Low: 54. Wind: WSW 5-10. Rain: 10%.

Thursday: Partly sunny, breezy and very warm. Scattered (possibly strong or sever) storms in the late afternoon & evening. High: 72. Wind: SW 15-30. Rain: 50%.

Thursday Night: Rain and a few storms. Some may be strong before 3 AM. Low: 54. Wind: NW 10-17. Rain: 50%.

Friday: Showers ending early. Partial clearing & turning cooler. High: 57. Wind: NW 10-20. Rain: 30%.

Saturday: Mostly sunny & cool. High: 53. Wind: N 5-10.
