Area Forecast Discussion National Weather Service Baltimore MD/Washington DC 928am EST Thu Jan 23 2025 Synopsis Arctic high pressure will maintain control leading to well below average temperatures through this morning. Temperatures will begin to moderate late this week as high pressure begins to lift away. A weak system may approach the region early next week. Near Term - Through Tonight Longwave troughing will continue toward the Mid-Atlantic today allowing for surface high pressure to weaken. Embedded in the mean upper level flow are several pieces of shortwave energy which will bring periods of high level cirrus across the area later today along with light upslope mountain snow. Meanwhile, a weakening cold front will work east from the Ohio River Valley late today before crossing the region late tonight into early Friday. West to southwest flow will ensue ahead of the boundary pushing highs toward or just above freezing mainly east of the Allegheny Mountains with low to mid 20s further west. This is still 5 to 10 degrees below normal from where we should be this time of year, but an improvement as we begin the climb out of the Arctic freezer. Clouds increase over the mountains later this afternoon and evening with increased cirrostratus further east. The added high cloud cover combined with subtle warm air advection ahead of the weakening cold front will yield low temperatures in the mid to upper teens and low 20s. Conditions will remain dry for most with light upslope snow showers expected across the Alleghenies through Friday morning. Snow accumulation of 1 to 2 inches are possible with locally heavier totals at elevations above 3000 feet. Overall moisture is limited although snow character remains fluffy given high snow to liquid ratios. Short Term - Friday Through Saturday Night Other than possible lingering upslope snow, dry conditions are expected Friday with high pressure. A dry frontal passage will turn winds W/NW, resulting in highs a few degrees cooler than Thursday, but mostly west of the Blue Ridge. Low temperatures will be a few degrees cooler as well, in the single digits and teens. Southwesterly flow with mostly sunny skies are expected on Saturday. High temperatures will rise to the 30s to low 40s (20s in the mountains) and lows will be in the 20s to low 30s. Long Term - Sunday Through Wednesday Snow showers in the upslope areas of the Appalachians will come to an end midday Sunday. High pressure will build into the region later Sunday and persist into Monday. Highs Sunday will be near average with high reaching the lower to middle 40s. Much of the same temperatures expected on Monday. A low pressure system is expected to track well to our south Monday night through Tuesday evening. There is a slight chance for some light rain across eastern portions of Virginia and far southern Maryland. A chance for snow showers in the Appalachians is also possible Monday night through midday Tuesday with an upslope wind and high pressure nosing into the region. High pressure will bring dry conditions Tuesday afternoon through Wednesday for nearly all areas except for the highest terrain in the Appalachians. Temperatures will remain near average both Tuesday and Wednesday. Marine Winds turn W/SW on Thursday. A dry frontal passage turns winds N/NW Friday and winds could gust to around 15kt in the afternoon, and may briefly approach SCA (Small Craft Advisory) criteria. On Saturday winds return to W/SW and could approach SCA (Small Craft Advisory) criteria late Saturday night. No marine hazards expected Sunday through Monday night. Winds southwest becoming northwest 10 knots Sunday and Sunday night. Winds becoming southwest again around 10 knots Monday and Monday night.
