Watch up until 10pm

URGENT - IMMEDIATE BROADCAST REQUESTED
   Severe Thunderstorm Watch Number 632
   NWS Storm Prediction Center Norman OK
   315 PM EDT Thu Aug 27 2026

   The NWS Storm Prediction Center has issued a

   * Severe Thunderstorm Watch for portions of 
     District Of Columbia
     Central Maryland
     Central Pennsylvania
     Northern Virginia
     Eastern Panhandle of West Virginia
     Coastal Waters

   * Effective this Thursday afternoon and evening from 315 PM until
     1000 PM EDT.

   * Primary threats include...
     Scattered damaging wind gusts to 70 mph possible
     Scattered large hail events to 1.5 inches in diameter possible
     A tornado or two possible

   SUMMARY...Thunderstorm coverage and intensity is expected to
   increase across the region this afternoon as a shortwave trough and
   attendant cold front approach from the west. Warm and moist
   conditions have fostered strong buoyancy across the region while
   increasing mid-level flow contributes to strengthening deep-layer
   vertical shear. These environmental conditions support the potential
   for strong to severe thunderstorms, with damaging wind gusts and
   isolated large hail as the primary risks. A low-probability risk for
   a brief tornado or two exists as well.

Watching that Frederick/Montgomery cell for me (in Colesville tonight). Might miss me to the north but it does seem to be having a tendency to come south.

Really strong storm just sprung up NW of Manassas

Taking forever to come south and east

Incredible repetitive full sky lightning ahead of the hoco moco cell - beautiful.

Maybe trying to cycle back up a bit - doubt it will get back to as intense as it was - but more lightning near Gaithersburg on the last update.
