Calderon Posted April 5, 2017 Share Posted April 5, 2017 RFD has overtaken the circulation, so the tornado threat is pretty much near 0 now but the hail threat is still kicking. Link to comment Share on other sites More sharing options...
LithiaWx Posted April 5, 2017 Share Posted April 5, 2017 It's absolutely ripping here in Douglas County. The rain is very intense, lots of lighting with house rattling thunder. Long, Long day ahead it looks like out here. Curious to see what this morning convection does later in the day. Link to comment Share on other sites More sharing options...
Wmsptwx Posted April 5, 2017 Share Posted April 5, 2017 Tbh, the intensity and overall coverage of this morning convection is more significant than I was picturing. Thinking it is a major reason they stuck with MOD in latest update. Link to comment Share on other sites More sharing options...
jshetley Posted April 5, 2017 Share Posted April 5, 2017 The enhanced risk got pulled back up to the NC border in our area, about a 30 mile shift to the north. The moderate risk stayed about the same, from Greenwood and Abbeville southward. All of upstate SC now has at least a 10% chance of a tornado within 25 miles, except right on the NC border. The damaging wind threat went up too, from 15% to 30% over upstate SC along and south of I-85. Link to comment Share on other sites More sharing options...
Calderon Posted April 5, 2017 Share Posted April 5, 2017 North of Mobile Quote The National Weather Service in Mobile has issued a * Tornado Warning for... Northeastern Washington County in southwestern Alabama... Central Clarke County in southwestern Alabama... * Until 830 AM CDT * At 759 AM CDT, a severe thunderstorm capable of producing a tornado was located near Saint Stephens, or 11 miles northeast of Chatom, moving east at 35 mph.

Now, if there were reports of wind damage and/or tornadoes then I would be concerned. This is the blowing up of the convergence of along the warm front. I'm going to be start being alarmed if there is a true lull after this moves out. Link to comment Share on other sites More sharing options...

The warm front is best to find using station plots. It's between BHM and Cullman stretching across and bisecting the ATL metro right now. Link to comment Share on other sites More sharing options...

On the HRRR and the RAP(I believe) radar output is used in order to give a more correct initialization of convection. Since these radars are down, these have a huge blind hole they cannot see into. However, modeled convection should not be affected in these areas. However, the accuracy of the model may be hindered some. Link to comment Share on other sites More sharing options...

The model is essentially missing the swath of convection near Atl as well as near BHM where radars are up? Link to comment Share on other sites More sharing options...

Could be a huge issue later on. yeah that really sucks. hrrr does a pretty good job a lot of the times. i'm surprised the 12z run didn't improve with input from ffc radar though. 27 minutes ago, LithiaWx said: It's absolutely ripping here in Douglas County.

Mrwolf1972 Posted April 5, 2017 Share Posted April 5, 2017 any idea how soon the clouds might vacate eastern tn so we can get some day time heating cause we are not looking to get any of the storms to the south anyone have a best guess ? Link to comment Share on other sites More sharing options...
Vicious Fluid Posted April 5, 2017 Share Posted April 5, 2017 Hello, long time observer here. Shoutout to all the Mets on here, this forum has helped me IMMENSELY in the past, and I come here as often as I do TWC. Its coming down pretty hard here in Buford (35 minutes NE of ATL). Has been for about an hour. No hail yet but lots of CTG lightning and very intense rain. Curious to see how this downpour affects later development ...

LithiaWx Posted April 5, 2017 Share Posted April 5, 2017 It looks like the southern edge of the convection around Atlanta is starting to move north. If we get clearing and sun down here watch out!!! Link to comment Share on other sites More sharing options...

I've been watching that stuff in Alabama and it is starting to move more northward than eastward in the last several frames of the radar. If we look at the GOES 16 visible satellite the LLJ from the SW is starting to take its role in movement of the morning convection. I feel there is a lull about to start taking place in the next 2 hours. The convection associated with the front from last night in TX, LA, and AR has all but gone, so we will have watch what the LLJ about to do very closely. There is talk that the LLJ may diverge.

It doesn't have to lift completely north of Atlanta for it to not affect what may play out here. Plus, you have that whole cluster in central and southern Alabama, so I'd concentrate on that more than what is near BHM. You have a significant amount of cloud debris.
