stay dry unlike me

[Stormsfury]

We're actually under bright sunny skies right now, but back in SE GA, supercells are exploding ... and is causing me some concern, since the TW was re-issued including my county in South Carolina.

A very long afternoon, indeed.

[JQ Public]

youch...stay dry and grounded then

[GAStorm]

I just looked at the radar in SE GA and the storms are definitely intense. As far as my area goes, no severe weather expected with temps still in the 50's. Our local met said temps would reach 74! Boy was he way off!! Stay safe Stormsfury!

[isobar]

Some impressive rainfall totals! Any severe weather at your location, SF?

[Stormsfury]

I didn't have any severe weather, aside from the flooding rains.

However, there were many vicious CG strikes (Cloud to Ground lightning) and with some of the storms, wind gusts to 35 mph occurred.

3.37" of rain so far.
2.76" at CHS WFO (record for the date) - old record was 2.01" (2001)

[isobar]

Sounds like you had quite a display of fireworks too.

[Stormsfury]

Sounds like you had quite a display of fireworks too.

Definitely yes.
The one that struck around 6:50 am this morning jolted me right out of bed. I didn't fall asleep last night until late (like 2:30 am).

Needless to say, I took a long afternoon nap.

[isobar]

I know what you mean, SF. I had one of those roll through last week at 5am. Thunder and pea size hail make for one loud alarm clock!

The storms continued during the early morning as well (The tornado watch ended at 9 pm, and in its place a severe thunderstorm watch until 3 am) so for 24 hours straight, my area was covered by some kind of convective watch.

No severe again here last night and early morning, and some additional heavy rains, but nothing like yesterday morning. However, in Neighborhooding Berkeley County, Storm spotters reported 1.25" diameter hail.
