The extended forecast calls for a sunny sky followed by clouds on Tuesday with a low in the mid 30s and a high in the lower 40s. A chance of rain or snow early Wednesday, then clouds and sun later in the day. The low will be in the lower 30s and the high will be in the upper 30s. Mostly sunny and cold on Thursday with a low in the mid 20s and a high in the mid 30s. Mostly sunny and cold on Thursday with a low in the mid 20s and a high in the mid 30s.

Temperatures overnight settled back into the lower and middle 30s around the Annapolis area. Under the influence of high pressure, we will see plenty of sunshine today along with above-average temperatures. By later this afternoon, readings will top 55 degrees at many locations. Some inland spots may hit 60, but right along the bay shore we can expect slightly cooler conditions. The center of high pressure will gradually shift east overnight and into Sunday, but its influence will continue with more sunshine and highs in the 50s on Sunday. Meanwhile, a cold front is expected to move from west to east across the area by early Tuesday. Precipitation associated with the front may fall in the form of scattered rain and snow showers, but no accumulation is expected as temperatures will be marginally cold and the system will contain little moisture. The air behind the front will be cooler, but seasonable with highs in the 40s on Monday. As we move through the week, two main weather features will impact the Middle Atlantic states. One will be the return of arctic air that will surge toward the coast and plunge temperatures 10 to 15 degrees below average. Another will be the potential for a moderate snow event by the middle of the week as low pressure forms just off the North Carolina coastline and spreads moisture into the Chesapeake Bay region. This is not expected to be a major storm, but an accumulation of snow is possible in Washington, Annapolis, and Baltimore on Wednesday. Thereafter, our weather will be calm but very cold with highs only in the 30s on Thursday and Friday.
