Confidence is currently low, but a mix of snow, sleet, or freezing rain is possible for a few hours, with higher chances for BWI/MTN. Precip may change to rain before ending by Tuesday afternoon. MVFR ceilings may develop Tuesday night as high pressure builds to the north and low pressure develops off the coast. Primarily VFR conditions are expected Wednesday and Thursday as high pressure builds back into the area. However, some MVFR ceilings are possible Wednesday into Wednesday night if a stratus layer develops. This is due largely in part to a stalled frontal boundary and area of low pressure sitting south and east of the region. Additional periods of sub-VFR are possible Friday through Sunday as another series of fronts cross the region. AVIATION...ADS/EST Update as of: 847 PM EST Sun Dec 22 2024
