Transient supercells, but too isolated is a new one for me

Mesoscale Discussion 1521 NWS Storm Prediction Center Norman OK 0136 PM CDT Thu Jul 13 2023 Areas affected...Portions of eastern WV...VA...DC...western/central MD...and central/eastern PA Concerning...Severe potential...Watch possible Valid 131836Z - 132100Z Probability of Watch Issuance...40 percent SUMMARY...Some threat for damaging winds and hail may exist as thunderstorms move eastward this afternoon. The need for a watch remains unclear, but trends will be monitored. DISCUSSION...Scattered thunderstorms have developed this afternoon across parts of the central Appalachians. More isolated activity is attempting to deepen across parts of north-central into northeastern PA, closer to the upper trough over NY and southern Quebec. A surface lee trough is present along/east of the Appalachians/Blue Ridge Mountains, with ample daytime heating acting to steepen low-level lapse rates. Latest mesoanalysis shows a relative minimum in instability along/east of the lee trough across parts of central/eastern VA into central MD and eastern PA. This area appears to have shallower low-level moisture based on area 12Z soundings, and some lingering MLCIN. Still, various RAP/NAM forecast soundings across this region suggest that a well mixed boundary layer will support at least an isolated damaging wind threat with any convection that can spread eastward off the higher terrain this afternoon and evening. Around 25-35 kt of deep-layer shear should also foster some thunderstorm organization, with multicells to marginal supercells possible. Some hail may occur with the strongest cores. With better large-scale ascent focused farther north across NY and New England, overall thunderstorm coverage remains uncertain. The need for a Severe Thunderstorm Watch this afternoon is also unclear, but observational trends will be closely monitored. ..Gleason/Bunting.. 07/13/2023 ...Please see www.spc.noaa.gov for graphic product...

Excessive Rainfall Discussion NWS Weather Prediction Center College Park MD 353 PM EDT Sat Jul 08 2023 Day 2 Valid 12Z Sun Jul 09 2023 - 12Z Mon Jul 10 2023 ...THERE IS A MODERATE RISK OF EXCESSIVE RAINFALL FOR PORTIONS OF THE MID-ATLANTIC INTO WESTERN NEW ENGLAND... ...20Z Update... ...Mid-Atlantic through New England... In coordination with all the forecast offices from DC/Baltimore north through New England, a Moderate Risk area was introduced with this afternoon's update for portions of the Mid-Atlantic into western New England. All guidance continues to hone in on a corridor of heavy rainfall caused by numerous training showers and thunderstorms developing across the Moderate Risk area Sunday afternoon for southern and western areas, then progressing through New England Sunday Night. Expect a widespread 2-4 inch event especially from eastern PA north through VT. However local amounts are likely to exceed 6 inches of rain, with the most likely areas for the higher rainfall totals through the Catskills/Poconos of NY/PA and also through the Green Mountains of VT. Much of this area has been very hard hit in recent days with heavy rainfall, with a large area over 300% of climatological normal rains per 2-week AHPS data. Adding a stalling front into the mix which will allow for training of abnormally high moisture air on the order of PWATs to 1.75 inches makes for a likely scenario for flash flooding, especially when adding terrain influences into the mix. With the full day's worth of HREF data first available at 12Z, it's notable that portions of east central VT have a 30% chance of exceeding 100-year annual return intervals for the amount of rain expected, with the Catskills/Poconos and Green Mountains all over 70% chance of exceeding 3 and 6 hour FFGs Sunday afternoon and evening. The steady signal of widespread rain and good model agreement on both timing and areal amounts added enough confidence to the forecast to upgrade to the Moderate Risk for this update.

@CAPE should be getting some good rain

Impossible since that jackpots @BlizzardNole

I am guessing some what look like mamamtus clouds by Nats Park? I'm at the game tonight and this is what I see over the LF foul pole

Baseball to softball sized hail at night

Hope you had a great birthday @WxWatcher007! Hope you are having a great chase day as well
