End-of-the-day-ish storm reports. Out of the damaging wind reports, 25 are tagged with 'possible tornado.' So we're gonna have much more than 25 tornado reports once all is said and done.

Supercells are still going. This one near Pensacola might produce

Surprised severe wasn't issued already as there was a tornado warning out.

Valid 311607Z - 311730Z

   Probability of Watch Issuance...80 percent

   SUMMARY...Isolated wind damage is possible early this afternoon as
   storm develop in western Pennsylvania/Maryland. Storm intensity is
   expected to increase later this afternoon into central/eastern
   Pennsylvania and adjacent areas of Maryland. Trends will continue to
   be monitored for a watch issuance.

   DISCUSSION...Cloud cover has continued to clear across West Virginia
   into western Pennsylvania as mid-level dry air overspreads the area.
   Though MLCAPE values remain below 300 J/kg, surface heating has
   brought temperatures in southwestern Pennsylvania into the upper 60s
   F. Low-level lapse rates are likely steepened enough to support a
   risk for damaging wind gusts given 50-60 kts of wind within the
   lowest 2 km on regional VAD winds.

   Into central Pennsylvania, more time will be require to destabilize
   as cloud cover has kept temperatures in the mid/upper 50s F.
   However, with the decreasing cloud cover expected, an increasing
   severe risk will probably occur by mid-afternoon. Southerly winds
   should advect increasing moisture into the area as well.

   Limited buoyancy and veered surface winds in western Pennsylvania
   will limit the tornado risk with early activity. Surface winds will
   remain more backed in central/eastern Pennsylvania along with
   greater 850 mb wind speeds. The greater tornado threat is likely to
   exist farther east and later this afternoon.

Mesoscale Discussion 0375 NWS Storm Prediction Center Norman OK 1048 AM CDT Thu Mar 31 2022 Areas affected...Parts of eastern Georgia into the Carolina Piemont Concerning...Tornado Watch 85... Valid 311548Z - 311715Z CORRECTED SEVERAL TYPOS The severe weather threat for Tornado Watch 85 continues. SUMMARY...Isolated to widely scattered vigorous thunderstorm development, including the risk for supercells capable of producing tornadoes, appears increasing probable through 2-4 PM EDT. Trends are being monitored for the possibility that this may require a new severe weather watch. DISCUSSION...Within the pre-frontal plume of higher precipitable water content, which is generally aligned with the strong southerly low-level jet (including 50-60 kt around 850 mb), remnant convectively generated cloud cover and precipitation is widespread. However, breaks/thin spots in the overcast are allowing for weak destabilization of the moistening boundary layer, and this appears to be contributing to at least some intensification of embedded deeper convection. Most notably, currently, this includes an organizing cell to the west of Waycross GA, but similar intensification may be underway across the Piedmont of South Carolina. With increasing breaks in the cloud cover probable into early afternoon, these trends may continue. Model forecast soundings suggest that low-level hodographs near the strong 850 jet axis are in the process of becoming characterized by increasing clockwise curvature, conducive to the evolution of supercells with increasing risk to produce tornadoes. While these may remain isolated to widely scattered due to the limited instability, a new severe weather watch may be needed within the next couple of hours. ..Kerr.. 03/31/2022

Not to distract from the current situation, but the Springdale, AR tornado from last night has been upgraded to an EF3. First EF3 in Tulsa's CWA in a long time. I'll have to go back and look later but I can't remember any off the top of my head in the last few years.

 

So I went back and took a look and the most recent EF3 I could find in TSA's CWA was 12/31/10. So yeah it's been a while. Over 11 years is quite the streak there. There was a likely EF3-EF4+ on 11/30/18 but it was only rated EF2 since it didn't hit much thankfully.

I'm gonna have to get used to that new color scheme. Didn't even realize they changed it until now

It was changed a few weeks ago, the intent looks like that it's to help familiarize the other color schemes the NWS uses

Well I think this is gonna be a standout March

 

Per Wikipedia, the 3 March tornado outbreaks combined had 28 EF2+ tornadoes. Still a lot of surveying to do for the 30th, so that number will rise.
