Flash Flood and Possible Isolated Tornado Threat Thursday - Saturday

1,067 views

An area of low pressure is expected to come out of the Gulf of Mexico and up the east coast, while another disturbance approaches us from the West in the Thursday - Saturday time frame. These two systems will attempt to pump in a rich plume of moisture from the south and east, setting the stage for heavy downpours with any showers and thunderstorms that develop. No widespread severe weather is expected, but I would not rule out an isolated tornado with this system(s) ... with a somewhat favorable wind field, despite the lack of instability. Remember, you don't need a crap load of instability for rotating updrafts/supercells ;)

Still a lot of certainty, but the potential for the above is certainly there.

12z GFS from this morning valid 00z Friday.
