Baltimore, Maryland

There is an interesting week coming for the east coast. How early will the nasty weather arrive in Baltimore?

At 554PM, ET, Baltimore was reporting a temperature of 35 degrees with clear skies. There was a weak wave off the coast of New England producing some clouds, and a developing system off the Carolina coast that promised to enhance overnight and bring some thunderstorms to Florida and Georgia tonight. Baltimore was safely between the two systems with no threat of shower activity in the short term. As the low off the Carolinas develops, however, there will likely be a few showers tomorrow morning.
A deep trough developing over the center of the country will generate an overriding onshore flow in the mid-Atlantic that will cause moisture to languish in the mid Atlantic through the day tomorrow. The trough will feature a dissipating surface low over the Great Lakes, which will be responsible for keeping Baltimore cloudy on Tuesday as well as Monday. The shower activity will begin to diminish late on Tuesday as the base of the upper level trough taps into the Gulf of Mexico. A strong surface system, the well advertised “Santabomb” will initially draw moisture away from Baltimore and give the area a break on Tuesday night.
Tomorrow – Scattered showers, heavier in the evening High 38, Low 28

NWS: Tomorrow – A chance of rain, mainly after 9am. Mostly cloudy, High 37, Low 30
Tuesday – A chance of rain. Cloudy, High 47, Low 37

WB: Tomorrow – Partly sunny in the morning…then becoming cloudy High 35, Low 30
Tuesday – Cloudy with a 30 percent chance of rain. High 45, Low 35

WN: Tomorrow – Mostly Cloudy with Areas of Rain High 37, Low 34
Tuesday – Cloudy with Chance of Light Rain High 48, Low 36

The high on Monday may well come at midnight as the flow switches to come strongly from the south. I doubt it. But it could.
