Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 353am EDT Thu July 17 2025 Synopsis A cold front approaches the area from the northwest today as surface high pressure remains over the southeast. The cold front will stall over the region on Friday and remain nearby through the middle of next week. Near Term - Through Tonight A cold front approaches from the northwest today as hot and humid conditions continue. High temperatures will be in the low to mid 90s for most of the area with dewpoints staying in the mid 70s. This combination will yield heat indices of 100-105 for portions of the area with higher elevations staying in the 80s to 90s. For this reason, a Heat Advisory is in effect from 11AM to 8PM today portions of the I-95 corridor and southern MD. Shower and thunderstorm chances will be highest along and west of the Blue Ridge, although a thunderstorm farther each cannot be ruled out. Compared to previous days, storm coverage will be less as dry air aloft and westerly winds inhibit severe potential. That being said elevated DCAPE levels will continue the threat of stronger convection producing downbursts. Overnight low temperatures will be in the 60s west of the Blue Ridge and 70s along and east of the Blue Ridge. Short Term - Friday Through Saturday Night Shower and thunderstorm chances continue Friday as a stalled front remains nearby. Precipitation chances will be highest in the southwestern portions of the forecast area due to being on the warm side of the boundary. As the boundary drifts northward on Saturday, precipitation chances increase to around 75% across the forecast area. Both days, a warm and humid airmass will lead to a severe weather threat with isolated to scattered instances of flash flooding possible. High temperatures will be in the 80s for most both days with higher elevations staying in the 70s. Overnight low temperatures will be in the 60s for locations west of the Blue Ridge and 70s for locations along and east of the Blue Ridge. Long Term - Sunday Through Wednesday Low pressure and an associated cold front will follow a warm front across the CWA (County Warning Area) on Sunday into Sunday night. Humidity in the region again will fuel showers and a few thunderstorms Sunday afternoon and evening. Highs Sunday could reach the lower 90s. The cold front will make its way south across southern VA and northern NC Monday. High pressure will build to the north of the front and north of our CWA as well. Most shower and thunderstorm chances should stay across our southern zones Monday afternoon and evening. Much of the northern areas should be dry or at least have a slight chance of showers. Highs in the upper 80s. High pressure will try to nudge farther south Tuesday and Wednesday. Thus, perhaps we will have minimal chances of showers anywhere or even a full dry day if conditions are right. Highs upper 80s to lower 90s. Marine A Small Craft Advisory remains in effect for the waters until 6PM this evening with southwest winds 10 to 15 knots and gusts up to 20 knots expected. Outside of SCA (Small Craft Advisory) conditions, there is a slight chance of showers and thunderstorms this afternoon and evening. SMWs may be needed, mainly in the northern portions of the waters. Winds decrease Friday and Saturday with SMWs remaining possible during afternoon showers and thunderstorms. No marine hazards Sunday through Monday night. There could be an occasional Special Marine Warning for parts of the Potomac River or Chesapeake Bay Sunday afternoon and evening with any convection. Winds southwest becoming northwest 5 to 10 knots Sunday and Sunday night. Winds becoming north to northeast 10 knots Monday into Monday night. Tides / Coastal Flooding Southerly winds will lead to elevated tidal anomalies through the end of the week. Annapolis is forecast to near Action Stage during high tide cycle tomorrow morning. Otherwise, the threat for tidal flooding appears low. NOAA Baltimore MD/Washington DC Office: Watches - Warnings - Advisories DC...
