There's a Winter Weather Advisory from 7 p.m. tonight through 9 a.m. Wednesday for icing from freezing rain mainly in the counties of Frederick and Washington and points west in Maryland.
Tonight: Cold Rain
Lows: 30s | Precipitation: 100%
Wednesday: Rain ending before noon; some sun possible late in the day
Highs: Mid 40s | Precipitation: 40% Early
Thursday: Mostly Cloudy; Rain could develop South of the area
Highs: Mid 40s | Wind: N 5-15 mph
An area of low pressure over the Southern Appalachians is moving along a stationary front that extends northeastward through the Carolinas and off the Outer Banks.
Rain will be widespread tonight…finally ending tomorrow morning. In higher elevations, west of Washington (as described above), freezing rain may result in icing conditions. High pressure will build into the area tomorrow afternoon. We may see some sunshine during the afternoon hours.
Thursday will be a cloudy day as a minor system passes just to our south. We have not included any precipitation in the forecast but it is not out the question. We will have a better handle on this possibility tomorrow. Friday and Saturday will be sunny. Clouds will increase later Sunday afternoon. On Monday, for the Inauguration, it will be partly to mostly cloudy and cold with highs in the middle 30s. A flurry or two is possible later in the day. Much colder air…the coldest of the season… will arrive for Tuesday and Wednesday.
