High risk for severe storms Friday

Although Thursday started out fairly comfortable, the wind will shift and allow the humidity to make things muggy once again in the Tennessee Valley. A few storms are possible this afternoon, but the higher probability of rain will hold off until Friday.

While all of the details aren't worked out yet, there are a couple of points of concern.  It's tentative right now, but in the morning, a strong line of storms can be approaching the Shoals out of the northwest.  At the very least, we're likely to see some gusty wind and very heavy rain.  That round exits Sand Mountain just after noon.  Be mindful, the consistency in the data with this first round is basically non-existent.  We may very well stay quiet until later in the evening, allowing the "energy" to build all day for the round of storms in the evening. 

Round Two appears to make it entrance later Friday evening into early Saturday morning.  At last check, timing is as early as 7 PM for storm arrival and as late as 10 PM Friday.  A line of storms shoots through the Valley from the north but once that line exits toward Birmingham by midnight, scattered storms push back in from the north through early Saturday morning.  

The storms later in the Friday hold the most potential for severe weather.  Damaging wind is the main threat, but second on the list is large, damaging hail.  While the tornado risk is fairly low, that's also a risk we are monitoring closely.

A few scattered storms linger into Saturday afternoon as well.  Behind the cold front, temperatures will be running in the upper 80s starting this weekend.
