Potential Weather Hazard:

A powerful storm system is expected to develop in the Midwest by next weekend, and will likely bring heavy rainfall to the region early next week.

Tonight and Beyond:
After a nice period of moderate snow earlier this evening associated with a Clipper system, skies will begin to clear, allowing temperatures to dip into the mid and upper teens. Gusty northwest winds will combine with the cold surface temperatures to produce wind chill values in the single digits.

Tomorrow, mostly sunny skies and diminishing winds will accompany high temperatures in the upper 30s to near 40 degrees to the south. Winds overnight Monday will then turn to the southwest, ushering in moisture and warmer temperatures ahead of a developing weak storm system that will pass to our north on Wednesday.

Rain showers should begin to overspread the immediate metro region between 2PM Tuesday afternoon, and 8PM in the evening. Showers will continue off and on through the night, before tapering from west to east Wednesday morning and early afternoon.

Significant Rainfall a Possibility Next Week:
A more significant storm system (appears it will be a rain system at this point), is forecast to move into the region next Sunday. An intense area of low pressure looks to develop somewhere in the Midwest on Saturday before rotating northeastward into southeastern Canada. A few models develop a scenario in which the DC metro and/or Mid Atlantic area experience torrential rainfall and the possibility of severe weather before the frontal passage.
