Musings about this svr sequence as it continues
tmrw will focus around the Iowa/Nebraska vicinity and to extents, Wisconsin. 300mb flow LeavingNeverlandHBO the region will make for a tricky day. As flow leaves the area, subsidence begins to fill in and as a result, a fairly capped warm sector and warmer 700mbs plague the region. The best hopes of initiation may be in SW WI, where 700mb temperatures may not be particularly warm, but with a dry slot advecting on top of this, CI could require several mergers. We will see. If anything fires, damaging wind/large hail is the possibility tmrw. There's a high chance we see near nothing tmrw convect in the warm sector.
Saturday
There are two regimes of focus for severe weather on this day. The Midwest/NE and ND/Canadian border
MIDWEST
We will have to see what trends do for the western portion of the risk as flow once again leaves subsidence over the area. However, a better signal for CI lies in Western PA
W PA
As the SE quadrant of this jet moves over the area, a isolated svr storm or two capable of damaging winds and a brief tornado of two will be possible. The western extent of the risk, i need to see CAM support but it's evident subsidence will play a part in stunting IL/IN.
ND/Canada
A LONG, broad belt of flow extends from the PNW all the way into the Dakotas, heading NE. While the jet does hit this area, 700mb temps appear to hit around 10 and while this is breakable, there's some uncertainty on if CI prevails. If any storm fires, damaging winds given high DCAPE and TD spreads are the main threat.
SUNDAY
A potentially notable severe weather event appears to be at play on Sunday with this slow moving long-wave trough continuing to persist. Once again, our main focus is ND/Canada. 300mb jet overlaps and severe storms initiate in a high moisture return/instability environment, consisting up of 4k SBCAPE. A strong LLJ will accompany this, supplying 240+ ESRH into the area. Weak mid level shear may lead to unusual storm behavior fod for this area, but at a cost, venting may also be a issue for storms. Regardless, profiles like 82/70 already being modeled leads to some concern for this area, and perhaps significant all hazards are already a likelihood on this day.
I'll continue to monitor trends but for now, good night!
