Severe Weather 2025

Dunno what the track record is for this model, but I came across this in my FB feed.


I do like the way the data are presented on this graph. On the public versions of what we are used to, you just see the upper limit of each area (e.g. 15, 30, 45). On this one, since the range of each color is specified (e.g. 5-15%; 15-30%), it seems to lend itself to providing a higher sense of attention and urgency.
 
Too early for specifics beyond Thursday-Friday, but 00Z CFS/GFS are quite active at least through the middle of next week, then the former suggests more systems through at least May 10th. All the days combined could affect a large swath including the Plains, Midwest, Ohio Valley and the South.
Thru May 10th is exactly what I stated in my Patreon post last night.
 
Pretty consistent signal though
Consistent patterns on model runs are definitely something worth paying attention to, as even if they may show differences in detail and may not verify verbatim, the general trends would still suggest that there's something going on.

It really is surprising how Alabama has (besides the 15th but Mississippi got the worst) avoided a very high caliber outbreak the past 4 years. Seems like every region has had a big outbreak in that time frame. ArkLaMiss, Western KY and TN, the Ohio valley, the plains last year. Even the northern plains got in on the action on 4/26 last year.

Alabama had a pretty quiet period in the mid 2000s before Super Tuesday didn’t they?
It does seem like at least some areas go through repeated cycles of low activity followed by high activity followed by low activity, etc. I admittedly haven't dug too deeply on that subject (at least not recently, anyway), but I do recall that, for example, while the Great Plains were suffering from the Dust Bowl from the 1930s, most tornado activity shifted eastward (most notably hitting the Southeastern US quite hard with at least several notorious tornadoes and tornado outbreaks).
 
Definitely looks like the Mid-South might be under the gun yet again come weekend. SPC has a D6 outline for this threat on Sunday. Models still a little shaky; a compact feature like this would probably be the most potent solution. The remainder of the month also looks to be active across much of the South and Plains.

That's quite the look for day 6 and analogs for day 6 on cips.
 
Euro for the win. GFS is just being the oddball as always. However, I will say that the dewpoints on the GFS are very favorable for severe storms. All 4 GFS runs today.

Here's the CPC Risk of Heavy Precipitation. Whenever I see CPC highlight a Slight Risk or any risk of Heavy Precipitation, that's a clear signal for severe weather potential
