The line of storms that is traking towards North Alabama is getting a little better organized. Should move into the Shoals around 11pm. Winds up to 60mph and isolated tornadoes possible between 11pm and 4am for North Alabama.
A line of storms continues to track east. A tornado watch is possible for North Alabama around 10pm. The main threat will continue to be straight line wind damage but isolated tornadoes are a threat too. Here is a timeline. Shoals: 11:30pm to 1:30am. Metro 1:30am -3:00am. Mountains 2:30am -4:00am. The latest forecast today on WAFF 48 News at Five.
A round of severe weather is still expected in the Heart of the Valley overnight. Here's the latest timeline for the storms with WAFF 48 Pinpoint Predictor:
Storms will arrive in the northwest part of state around or a little before midnight. Part or all of north Alabama will likely be under at Tornado Watch at this time. The primary severe weather risk will be from damaging winds in excess of 60mph and heavy rainfall. The threat for any tornadoes, though low overall, will be greatest at this point in time.
Storms will be heading through the Huntsville/Athens/Decatur area by 2am. Again the main threat will be damaging winds and heavy rain. A low tornado threat will still exist.
Storms will be pushing through Marshall, Jackson and Dekalb counties by 3-4am. They will be running out of gas at this point, but still could produce marginally severe wind gusts and heavy rainfall. The tornado threat appears fairly low at this point. Storms should clear the area by 5am with some lingering rain or showers through 8am Friday.
Plan on staying weather aware tonight. The WAFF 48 Storm Team will be here throughout the night tracking the storms on-air and online at WAFF.com
A cold front will bring a round of storms to North Alabama overnight Thursday into early Friday morning. While some showers and storms will likely develop during the day on Thursday the greatest risk for severe weather will fall between midnight Thursday night and 6am on Friday. Damaging wind appears to be the greatest threat. However a few isolated, relatively weak tornadoes will be possible as well, particularly as the storms reach the Shoals around midnight. Heavy rain with the storms could lead to some localized flooding.
As we head into severe weather season it's important to stay aware of the weather no matter where you are. WAFF is making that easier for you!

With the dry weather this week we've not been tracking anything with WAFF Live Doppler 48 Radar. But the radar can still show us a few things even when there's no rain or snow to be found. Here is an image from WAFF Live Doppler 48 from this morning around 6:40am:
The light blue areas are just ground clutter (buildings, trees, etc) that will show up near the radar in the absence of precipitation. The blue "spike" that you see stretching from Huntsville toward Scottsboro and Ft. Payne is something else. It is the radar picking up the rising sun. These are called "Sun Spikes".
Radars work by sending out a beam of radiation as they turn. When this beam of radiation strikes raindrops or snowflakes some of the radiation is reflected back to to the radar. Based on the intensity of the returned radiation and the time it took to return, the radar calculates how far away and how intense the precipitation is. The radiation that the radar emits and receives falls within a certain wavelength of the electromagnetic spectrum.
The sun emits radiation all across the electromagnetic spectrum, including the range that the radar uses. Right around sunrise and sunset there will be brief moment where the radar and the sun are pointing directly at each other. The radar picks up some of that solar radiation and "thinks" it's seeing precipitation. Instead what it is seeing is the sun coming up or going down.
The sunny, warm and dry weather of the last few days has been great for outdoor activities. However it's also been great for kicking up the pollen levels. If you're an allergy sufferer you may already be feeling a little congested and it may get worse in the coming days with more of the same weatherwise. Here's the pollen forecast for the next 3 days:
If you're sneezing and have the itchy watery eyes, blame the Juniper and Ash trees....they are the main pollen producers right now.
