5% tornado area added for tomorrow. The enhanced risk is right over areas currently in extreme drought so hopefully they can cash in with some good rain. There will probably be some massive hailers, at least initially while the storms are discrete, luckily this will be over a mostly rural area. Could actually end up as a solid chase day if the storms can remain discrete. 

As for today, the HRRR has been pretty consistent in only showing one cell firing in the main slight risk area. As I said yesterday, I don't really see a whole lot happening, but if anything actually does form it could be pretty explosive.

CIPS analogues for Saturday are a lot more interesting than I expected, including 5/19/13, and 5/8/03, and a few others. 

We'll see what the CAM's show, but I'm a bit more confident in storms developing around here Saturday than I have been for the recent slight risks.

I'm actually shocked that they put out 5/19/2013 as a analog. I've also discovered that 5/20/2013 is also included as well.

Agreed about significant severe weather potential with the discrete cells but I can’t imagine they’d stay discrete for much longer than an hour. Should also occur while the sun is setting which will make the storms look real nice and then real… dark

Not sure i've ever seen a hail report without a measurement. Sounds like it's on the big side.

Yeah I don’t know exactly how high reflectivity was but it looked like 75+. 
 

“Increasing concern” for supercells. 60% chance for watch. Gonna go ahead and renew my Radarscope pro at least for a month. It’s been a few years since it expired and I never bothered getting it back

Edit: oh wow only $10 for a year. The hell?

Mesoscale Discussion 0528
   NWS Storm Prediction Center Norman OK
   0533 PM CDT Thu Apr 21 2022

   Areas affected...Southwest KS into extreme northwest OK

   Concerning...Severe potential...Watch possible 

   Valid 212233Z - 220030Z

   Probability of Watch Issuance...60 percent

   SUMMARY...Tornado watch is being considered for portions of
   southwest Kansas.

   DISCUSSION...Pressure falls in the lee of the Rockies will continue
   this evening such that low-level moisture should gradually advance
   north-northwest across the southern/central High Plains.
   Strengthening LLJ will aid this process as it focuses across western
   OK/southwest KS over the next few hours. Intense surface heating has
   contributed to a near-dry adiabatic lapse rate in the lowest 3km
   across the TX Panhandle into northwest OK and extreme southwest KS.
   As a result, boundary-layer cu are now developing along the eastern
   edge of this steep lapse-rate plume, extending into southwest KS
   (DDC region) where low-level convergence is focused. Satellite
   imagery suggests agitated cu field over eastern portions of DDC CWA
   may be close to producing showers. Current trends suggest
   thunderstorms may evolve over this region, and given the
   shear/moisture supercells are expected. Will continue to monitor
   this region for a tornado watch.

     A few tornadoes possible
     Scattered large hail and isolated very large hail events to 3
       inches in diameter possible
     Isolated damaging wind gusts to 70 mph possible

   SUMMARY...A couple of supercells are expected this evening across
   southwest Kansas, in a storm environment that will support the
   threat for isolated very large hail up to 3 inch diameter, and a
   couple of tornadoes.

   The tornado watch area is approximately along and 40 statute miles
   east and west of a line from 30 miles west northwest of Russell KS
   to 35 miles west of Medicine Lodge KS. For a complete depiction of
   the watch see the associated watch outline update (WOUS64 KWNS
   WOU9).

   PRECAUTIONARY/PREPAREDNESS ACTIONS...

   tornadoes and severe thunderstorms in and close to the watch
   area. Persons in these areas should be on the lookout for
   threatening weather conditions and listen for later statements
   and possible warnings.

   &&

   AVIATION...Tornadoes and a few severe thunderstorms with hail
   surface and aloft to 3 inches. Extreme turbulence and surface wind
   gusts to 60 knots. A few cumulonimbi with maximum tops to 550. Mean

Thought you guys might enjoy this, got a drone today so I decided to test it out on a small storm to the northwest

 

It's not the most exciting storm, just some rain in the distance, which you can barely see since it's not HD (had to record my phone screen since drone has no SD card). If we get any bigger storms in the next few days though I'll be sure to capture something for you guys!
