Conditions will be beautiful Saturday but changes will bring colder air and precipitation back by Sunday. Snow is  back in the forecast by Sunday night.

Tonight:
Mostly Cloudy, Fairly Mild
Lows: mid 40s to around 50 degrees
Wind: SW 10 m.p.h.
Saturday:
Partly Cloudy, Warm and Breezy
Highs: Mid 60s
Wind: W 10-15 m.p.h.
Sunday:
Mostly Cloudy, Late-Day Showers
Highs: Mid 40s
Wind: NE 5-10 m.p.h.

 Skies will be partly to mostly cloudy overnight ahead of a weak frontal boundary. Through the day tomorrow, skies will become partly to mostly sunny and it will become breezy and even warmer with highs reaching the lower to middle 60s. A cold front will cross the region tomorrow night. This will change the wind direction and allow somewhat colder air to filter into the area.

On Sunday, skies will become mostly cloudy and highs will only reach the middle 40s…a few showers could develop during the day. But the weather could become more of an issue Sunday night through mid-day Monday. This is because an organized area of low pressure will be moving from the Lower Mississippi Valley northeast towards the North Caroline Coast during that time frame. Precipitation is likely to gradually cover the entire region.

The big question is WHAT TYPE of precipitation will it be. Because temperatures will be so borderline…it may well turn out to be a location-dependent system. In other words, locations north and west of Washington mat wind up with mostly snow while areas south and east of Washington may wind up being mostly rain or a mix of rain and snow. There is the potential for enough frozen precipitation to have an adverse effect on Monday morning’s commute and attendant delays. The PRECIPITATION TYPE issue should come into better focus over the weekend. Stay tuned!
