Enjoy the spring-time warmth today because a bitter blast is on the way.

This Afternoon:
Mostly cloudy and unseasonably warm
Highs: Mid to upper 60s
Wind: S 5
Cloudy with rain developing; patchy fog possible
Temperatures: 50s
Wind: South becoming NW 5-15
Cloudy with showers
Temperatures: 50s falling into the 40s
Wind: NNE 5-10 mph

Today will be our final day of exceptionally warm temperatures, for a while.  Although it will remain cloudy, highs will soar into the middle and even upper 60s. 

Keep in mind, our average high is 50 degrees.  Big changes are ahead, though.  Check out the plunge of arctic air associated with the front that is drawing near us.

As this potent cold front approaches the area, rain showers will develop overnight with mild temperatures in the 50s.  The front will slide through very early Friday and temperatures tomorrow will fall from the 50s tomorrow morning into the 40s by the afternoon with occasional rain showers. 
Rain will become more likely through the day, which is not ideal for the National Christmas Tree lighting ceremony at 4:30pm.  Rain will wrap up early Saturday morning and most of Saturday will be dry.  By Sunday, another front will move into the area and this one will bring the really cold air and also the possibility of a wintry mix. 
It is still too early to nail down specifics, but at this point, anticipate the potential for periods of snow, sleet, cold rain, and possibly freezing rain. By Monday, temperatures will rise above freezing for a cold rain event Monday and then bitterly cold air settles in for the middle of next week.  Highs will only be in the low to mid 30s!
