Near 70 today; 60s Thursday; 50s Friday. That's how the forecast from Sterling goes this afternoon. And they're throwing in rainy days for Thursday and Saturday for good measure as a cold front and coastal low affect the region.

The most interesting thing in the seven-day predictions from the NWS is the temperature drop. Central Maryland will be looking at overnight lows in the 30s by Thursday night into Friday, after daytime highs sink from near 70 today, to the 50s on Friday. 

Low pressure tracking along the front will encounter that cold air early Friday, "That could provide a brief period of snow showers or snow/rain showers at the conclusion," forecasters said today, especially in the western mountains. The real accumulating snow will fall well to our north, as the AccuWeather.com map above shows.

After a sunny day Friday, they're expecting a coastal low to move this way, running into still-cold air at the surface. "There's still uncertainty as to how everything will unfold," forecasters said. "And since boundary layer temps still on the cool side, am also uncertain as to what form precipitation would come overnight as if it did fall. Would stay tuned to the Friday night/Saturday forecast..."

Sunday looks sunny and nice, as do the first days of the new work week, with daytime highs creeping back up through the 50s.
