Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 914pm EDT Thu April 24 2025 Synopsis High pressure will move to the offshore waters of the mid- Atlantic Coast tonight. A strengthening low pressure system will approach from the west on Friday into Friday night. The associated warm front will lift through the region Friday, followed by a cold front on Saturday. Canadian high pressure settles in on Sunday into early next week. Near Term - Through Friday Current satellite imagery shows some very thin high clouds still present across much of the area. Clouds will gradually continue to thicken overnight, but no precipitation is expected. Winds will be light out of the south, with overnight low temperatures generally in the low to mid 50s. Short Term - Friday Night Through Saturday Night Low pressure over the Great Lakes will swing across the Great Lakes region Friday. A developing warm front will meander into and across our region Friday before lifting northward Friday night into early Saturday. This warm front could spawn rain showers and a few thunderstorms Friday, mainly west of the US 15 corridor. Additional showers and thunderstorms could spread east into the metro areas Friday afternoon into Friday night as the warm front lifts across and out of the region. High temperatures Friday will be middle to upper 70s with near 80 reading from the metros to the Chesapeake Bay and lower 70s west of the Shenandoah Valley. While cloud cover, showers and perhaps a rumble of thunder still linger Friday night, low temperatures Friday night will be milder with lows in the upper 50s to lower 60s. With a warm front leading the way of warm and more humid air, additional showers and thunderstorms could develop Saturday morning through midday behind this warm front and ahead of a strong cold front that is expected to extend southwest from the Great Lakes low pressure system. Given the amount of moisture and humidity and warmth ahead of the cold front and the actual lift from the surface front and mid-level energy, some of the thunderstorms around midday Saturday into Saturday afternoon could be strong with heavy rainfall and gusty winds. Models seem to indicate that the cold front clears our region between mid- afternoon Saturday and early Saturday evening. Temperatures along and east of the Blue Ridge Mountains could punch into the 80 to lower 80s realm, while the further west in direction and up in elevation could quickly be in the 70s, if not 60s, with frontal passage on Saturday. Saturday night's lows could be 15 to 20 degrees cooler than Friday night. Long Term - Sunday Through Thursday High pressure of Canadian origin will build in Sunday as upper level troughing moves to the east. Breezy and cooler conditions will prevail, although temperatures in the mid 60s to lower 70s are only a few degrees below normal. Favorable radiational cooling may develop Sunday night as the high builds overhead. However, frost/freeze concerns appear to be minimal where the growing season has started as dew points are forecast in the mid to upper 30s. A warming trend will start Monday as the high slides to the southeast. Tuesday will feel a bit more like summer as a warm front lifts north and upper ridging builds overhead. Temperatures likely rise well into the 80s with dew points nearing 60. It appears any convective chances will be limited to northwestern parts of the CWA (County Warning Area) as remnant activity from the Ohio Valley moves in late in the day or overnight. A cold front will approach Wednesday, bringing a higher (but not definite) chance of showers and thunderstorms to the entire forecast area. While wind fields will have a modest increase aloft, the threat for stronger storms is uncertain due to questions about frontal timing and available forcing and instability. Fewer areas may reach 80 as clouds and shower chances increase, but it will still be a warm day. The front will likely stall near or south of the area Thursday, resulting in a persisting chance of showers along with slightly cooler temperatures. Marine High pressure will continue to push eastward tonight. Meanwhile, a warm front will lift through the region later tonight into early Friday. Sub-SCA (Small Craft Advisory) conditions are expected with light winds out of the S to SSE tonight. As the warm front pushes through Friday, showers and SCA (Small Craft Advisory) wind gusts are both possible, especially later in the day into the evening hours. SCAs (Small Craft Advisories) are in effect for all waters tomorrow afternoon, and for all waters but the Upper Tidal Potomac tomorrow night. Showers and thunderstorms impact the waters on Saturday as a cold front moves across the forecast area. Small Craft Advisories will likely be needed on Saturday, and some low end Gale gusts can't be ruled out late Saturday afternoon into Saturday night. Winds shift from southerly ahead of the front to northwesterly behind the front Saturday evening. Gusty northwest winds continue through Sunday with Small Craft Advisory conditions likely. Winds will lessen by Monday morning as high pressure moves overhead. Southerly winds may start increasing by Tuesday afternoon ahead of the next low pressure system.
