alexj7 Posted July 4 Share Posted July 4 I’ve lived in Maryland 4 years and I swear Frederick gets hit 10x for every one storm I get in North Rockville. I’ve yet to have lightning this calendar year besides some distant rumbles. Looks like more of the same. 1 Link to comment Share on other sites More sharing options...

Radar looks like shit for us https://www.wpc.ncep.noaa.gov/metwatch/metwatch_mpd_multi.php?md=0598&yr=2026 Mesoscale Precipitation Discussion 0598 NWS Weather Prediction Center College Park MD 544 PM EDT Sat Jul 04 2026 Areas affected...Central Mid-Atlantic Concerning...Heavy rainfall...Flash flooding possible Valid 042144Z - 050300Z SUMMARY...Expanding clusters of heavy showers and thunderstorms will impact the central Mid-Atlantic region this evening, including the I-95 corridor from central VA through Washington D.C. and into southeast PA and central NJ. High rainfall rates up to near 2 inches/hour will foster concerns for urban flash flooding. DISCUSSION...The late-afternoon GOES-E visible satellite imagery along with radar shows expanding clusters of heavy showers and thunderstorms expanding gradually off to the northeast across western and central VA, with recent development also noted across far northern VA, eastern WV and adjacent areas of west-central MD. The activity is growing upscale as weak shortwave/MCV energy crossing the central Appalachians ejects out into the very moist and unstable boundary layer pooled across the central Mid-Atlantic region. Surface observations show an elongated trough axis aligned rather close to the I-95 corridor from north-central VA through central to northeast MD, and into adjacent areas of southeast PA and central NJ. Along this boundary, MLCAPE values are as high as 2000 to 3000+ J/kg with PWs near 1.75 inches. This is a strongly conducive thermodynamic environment for strong to severe thunderstorms given the steep low and mid-level lapse rates, which will also be conducive for high rainfall rates. Regional hires models appear to be struggling somewhat with the overall convective details and rainfall potential, but radar and satellite trends along with recent data from the experimental WoFS suggest a corridor of rather organized thunderstorms capable of producing rainfall amounts of as much 2 inches per hour, with perhaps most of this falling in as little as 30 minutes. The overall convective threat should tend to align itself rather close to the aforementioned surface trough and generally near the I-95 corridor from northern VA through central and northeast MD, and into southeast PA and central NJ going through the mid-evening hours. Some localized storm totals of 2 to 3 inches will be possible as these clusters of thunderstorms advance generally northeastward this evening, and with the high sub-hourly rainfall rate potential, some areas of mainly urban flash flooding will be possible.
