Fresh arctic air is settling over the Mid-Atlantic and New England states today with unseasonably cold temperatures. Lows this morning dropped into the lower 20s around Baltimore and Washington, and afternoon highs only reached the mid to upper 30s. These temperatures are more than 20 degrees colder than average for this time of year, and the cold is quite impressive considering the full March sunshine. Meanwhile, an area of low pressure will form along the arctic front that recently moved through the region. This low will intensify rapidly and move up the Mid-Atlantic coast, but is expected to move offshore to the south and east of Cape Hatteras, North Carolina. As the storm develops and intensifies, precipitation around the low will fall in the form of snow in Baltimore and Washington on Tuesday. At the moment, the storm looks to be forming far enough off the coast to keep the heaviest precipitation to our east. Consequently coastal areas of Maryland and Delaware may pick up more snow than areas west of the Chesapeake Bay. In Baltimore and Washington, wet snow is likely during the day on Tuesday with a small accumulation possible on grassy surfaces. Snow showers may linger into Tuesday evening with another coating of snow possible. It will be very windy and cold on Tuesday with highs only in the mid to upper 30s with gusty winds wrapping around the intensifying area of low pressure. As we move through the week, temperatures will begin to moderate into the 40s and 50s as March comes to an end.
