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.

Updated 1730z SPC OTLK for Day 2 (tomorrow, Sunday) has added 5 hail and 30 wind Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1203 PM CDT Sat Jul 04 2026 Valid 051200Z - 061200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS THE MID-ATLANTIC SUNDAY AFTERNOON AND EVENING... ...SUMMARY... Scattered wind damage is possible with thunderstorms across the Mid-Atlantic Sunday afternoon and evening. Isolated strong storms also are possible across Montana and western North Dakota, and portions of the southern Plains to the Tennessee Valley. ...Mid-Atlantic... A weak surface low is forecast to move west to east along a sagging cold front/baroclinic zone draped across PA into northern NJ/southeast NY on Sunday/Sunday evening. Meanwhile, lee troughing will develop across VA. A hot and very moist airmass will reside near and south of these boundaries, which will serve as a focus for severe storm development during the afternoon and into evening. Southwesterly flow aloft will weaken through the day as an upper shortwave impulse lifts northeast of the region, but around 20-30 kt mid/upper-level flow will persist. Moderate to strong destabilization is expected and thunderstorm clusters are expected by early to mid-afternoon. Sufficient clustering could occur along the southward-sagging cold front and one or more forward propagating clusters will be possible from northern VA into southeast PA until storms move offshore the Mid-Atlantic coast during the evening. Sufficient consistency among deterministic/CAMs and AI/ML guidance exists regarding storm coverage to warrant an upgrade to 30 percent wind probabilities for portions of the region.
