Turned out to be juicy ahead of the front. Reports of 5+” around south LA today and I’m sure that will continue. Might see some 8+ areas today, and we still have a couple days to go.

So apparently Alabama is up to 25 tornadoes on 3/17. That makes 3/17 the 6th largest outbreak recorded in Alabama state history...

Re: Great Plains, Midwest, & Deep South Storm Season 2021
The Moderate risk is STILL somewhat broad, there is STILL a chance for a High Risk, I'm giving that chance a 30% . . .

I seriously hope we do not have another high risk in March. That would spell trouble!Iceresistance wrote:The Moderate risk is STILL somewhat broad, there is STILL a chance for a High Risk, I'm giving that chance a 30% . . .

I believe the night tornadoes will not flop this time like the last. The low level jet and upper level jet are going to be more powerful this time compared to last.

Re: Great Plains, Midwest, & Deep South Storm Season 2021

Re: Great Plains, Midwest, & Deep South Storm Season 2021
Those plots are noticeably more favorable for strong tornadoes than 3/17’s were. Srh values for that event were only 200-300 m2/s2 for most of the area except immediately near the warm front. If these model trends keep up I don’t see how we don’t get a high risk tomorrow. Only potential failure mode I can see is a cap that might not be strong enough to prevent too many cells from going up and crowding the area.

Re: Great Plains, Midwest, & Deep South Storm Season 2021
Anyone know the predicted atmospheric CAPE?
Also if we get a 10 on STP!!! That would warrant serious bad news.

Yes . . .

Also, the Supercell Composite is EVEN HIGHER than last week's outbreak . . .
The highest SCP last week was a 8
The highest SCP for Tomorrow right now is a 24

I'm about to take a look on the GFS & NAM soundings across Dixie Alley for Tomorrow . . .
I'm going to take a look at the soundings & post them here when I'm done . . .
