Please post your updates and observations here.

If you live in the Tennessee Valley, keep an eye on the sky and the other eye out for weather alerts.

Ping to today’s severe weather thread.

This watch has the same probabilities as yesterday’s PDS watch in NE Texas.

And it’s only 11:15 local. Gonna be a long, long day.

It is BUSH’s fault!!! (It will until Palin/Bachman get elected, then the LIBS will say it’s Palin’s Fault!!) :-)

Yesterday's first PDS watch was issued at 2pm local.

This one was issued nearly three hours earlier.

Make ya wonder what it will be like further east in Northern Alabama and Georgia when this severe weather scenario has the full afternoon heating keeping it cooking along.

HSV has another tornado warning and is under a severe flash flooding warning. Schools are closing. This is the worst weather I can remember and I have lived here since 1966.

Another tornado warning for HSV and area. Tornado near Decatur.

HSV?

[MamaB]

Sorry, Huntsville, AL.

From Wiki:

Terminal velocity of hail, or the speed at which hail is falling when it strikes the ground, varies by the diameter of the hail stones. A hail stone the size of 8 centimetres (3.1 in) in diameter fall at a rate of 48 metres per second (110 mph).

WOW. That means that the updrafts are 110mph+...probably much more + !! Thats SOME energy!

Some describe the appearance of the larger of these super cell thunderstorms as a mushroom cloud of an atomic explosion. But if they knew the energy involved, they’d know how close their description really is.

Supercells blowing up in NW Mississippi just east of the Miss River. Already have a tornado warning out.

Tornado watch just issued for Mid-Atlantic, Central NC, VA and parts of WV and MD up to PA border.

Fortunately, it's not a PDS watch like we had a few days ago with all of those horrific storms in NC.

[flutters]

Our local meteorologist, Jym Ganahl, in Columbus, Ohio, said yesterday that the storms moving in tonight have the same factors as the storms that produced the deadly F5 Xenia tornado in 1974.

I live in NE Mississippi near the confluence of MS/Tn/Al. Since this morning at 3am we've had six Tornado warnings and numerous Thunderstorm warnings. We also are in a high flash flood area. Last year this same time (May 1) we had the town flooded out and tornadoes damaging a bunch of property.

PDS watch just issued for most of Alabama:

Thanks. Was caught off guard here. Radio warning (Midland SAME) did not alert.
