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.

My house got 3-5 inches of rain Yesterday & Last Night

(Approx. measurement because my rain gauges broke last month)

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

Here it is guys, straight from the SPC summary for Day 2...

A potential outbreak of severe storms including several long track strong tornadoes, large hail and damaging wind will exist Thursday into Thursday evening across a portion of the lower Mississippi Valley and Southeast States.

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! :sick:

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.

WOW Those are impressive soundings 33.6 for supercells is ridiculous. Iceresistance is that higher than the last outbreak's soundings?(3/17)

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.

Anyone know the predicted atmospheric CAPE?
Also if we get a 10 on STP!!! That would warrant serious bad news.

Yes . . . :eek:

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
