frd Posted yesterday at 09:43 PM Share Posted yesterday at 09:43 PM 49 minutes ago, Weather Will said: WB 18Z 3K NAM has thunderstorms by midnight on the 4th in DC. Mount Holly has increased the rainfall probabilities for Saturday eve/night. SPC has highlighted much of our area in a Slight Risk (level 2 out of 5) for severe thunderstorms both Friday and Saturday. As indicated by the PoP forecast above, coverage of storms is anticipated to be relatively low on Friday, mainly isolated to scattered in nature at best. Coverage and organization of storms should be a bit greater on Saturday though. Damaging winds will be the main threat with any thunderstorm development. On Sunday, the severe weather threat may begin to become confined mainly to Delmarva where destabilization is greatest ahead of an approaching cold front. With that being said, the entire area could see showers and a few storms. SPC has highlighted this area with a day 4 15% severe risk. 1 Link to comment Share on other sites More sharing options...
frd Posted 4 hours ago Share Posted 4 hours ago Pretty sad that areas in lower Delaware which are so dry miss out on the heaviest rainfall potential according to this WPC forecast map. Link to comment Share on other sites More sharing options...
frd Posted 4 hours ago Share Posted 4 hours ago Ryan Maue @RyanWeather · 18h Watching with some concern about the "mother of all heat domes" across the Western U.S. in 10-12 days ... triggered by Super Typhoon Bavi. This would be unprecedented ridge strength at 6045 meters (500 mb height) Nobody has seen this before Ryan Maue @RyanWeather · 3h "Mega Typhoon Bavi" Super Typhoon Bavi has an opportunity in the coming 4-5 days to set the "world record" for the most intense tropical cyclone observed, since Tip in 1979. ECMWF HRES (00z) at 872 mb --> upper echelon of Earth's maximum potential intensity. 1 Link to comment Share on other sites More sharing options...
frd Posted 3 hours ago Share Posted 3 hours ago 693 FXUS61 KPHI 031900 AFDPHI Area Forecast Discussion National Weather Service Mount Holly NJ 300 PM EDT Fri Jul 3 2026 .WHAT HAS CHANGED... Confidence has increased in potential flash flooding impacts across portions of the area on Sunday and Monday. Otherwise, the forecast remains in track. Concern has grown this afternoon that a threat for flash flooding could evolve Sunday into Monday, given a slow moving or stationary frontal boundary draped across the area, and tall, skinny CAPE profiles with deep moisture. In fact, model guidance is indicating PWATs potentially exceeding 2 inches, which is above the 90th percentile for this time of year and near the daily observed maximum. Given these factors, rainfall rates in storms could exceed 1 to 2 inches per hour. As of now, the WPC has placed a Slight Risk (2 of 4) for the I-95 corridor and points west both Sunday and Monday, with a Marginal Risk (1 of 4) for the remainder of the area. The front is expected to finally clear the area Tuesday, with high pressure at least briefly building back into the region. However, daily chances for isolated, primarily diurnally driven convection, could continue through the middle of next week. 1 Link to comment Share on other sites More sharing options...
