Average Time of First Frost Across the National Capital Region

Average Time of First Frost Across the National Capital Region

It’s that wonderful time of year…cool crisp mornings, mild, sunny afternoons, the smell of wood burning in fireplaces, honey crisp apples, Halloween just around the corner… and of course the first frost/freeze of the season is only several weeks away.  Fall is without a doubt my favorite season.

Meteorological Fall begins September 1st and runs through the end of November. The Fall Equinox (first day of Autumn) this year comes Tuesday, September 23rd! The growing season will be coming to a close very soon. Happy Fall! The map above depicts when on average the first frost/freeze occurs here in the Washington Region. The further one goes from the warmth of the Chesapeake Bay and Tidal Potomac the earlier you can expect the first frost and or freeze as we head into the spectacular month of October.

A strong cold front will approach the Washington Region on Thursday afternoon touching off scattered showers and thunderstorms. Some thunderstorms could contain damaging winds and hail. Highs on Thursday will climb into the lower 90s with a noticeable increase in humidity. The heat and humidity, and strong winds aloft will aid in the development of scattered strong to severe thunderstorms.

Behind the front, temperatures will begin to slide to well below normal levels as we head through the weekend and into the middle portion of next week. High temperatures will only rise into the lower to middle 70s with lows possibly dipping into the 40s in the suburbs and middle 50s in the cities!

Happy Meteorological Fall

Summer Pattern Setting Up through Mid Week

August 30, 2014

Summer has almost been absent this year but things are about to change as we head back to school and work on Tuesday.  An upper level ridge will build across the southeast pumping heat and humidity into the Mid-Atlantic and New England. Temperatures on Tuesday may soar into the lower to middle 90s.  Saturday through Labor Day looks typical around Washington with partly cloudy skies, highs in the middle to upper 80s and scattered afternoon showers and thunderstorms.
