What a spectacular Spring it has been across the Mid-Atlantic with periods of low humidity and mild temperatures more similar to what you would find in New England during this time of year.
Below are four images taken from the latest climate forecast system (CFS) model specifically looking at the possible temperatures (departure from normal in Celsius) through June 20th. While there will be periods of heat and humidity, it looks as though there will also be periods with low humidity and cooler temperatures.
A cool front will approach the DC Region on Wednesday touching off scattered showers and thunderstorms. The front should clear the area by Thursday afternoon or evening allowing for high pressure to begin building into the region on Friday.
High temperatures on Friday and Saturday will rise into the middle to upper 70s. Sunday and Memorial Day will feature warmer temperatures with highs making into the 80s.
A strong cold front will pass slowly through the DC Area Thursday night through Friday’s rush hours creating ripe conditions for heavy rainfall and flash flooding.
While the majority of the D.C. Region may pick up between two and three inches of rain, there may be spots that recieve closer to four inches before the system clears our area on Friday evening.
The upcoming weekend will feature a mix of clouds and some sunshine with high temperatures holding in the 60s to near 70 degrees.
The upcoming work week will feature seasonal temperatures through Thursday with lows generally in the 50s and highs reaching the lower to middle 70s. There may even be several periods of showers in the DC Region as cooler air over New England clashes with warmer air over the Carolinas.
A warm front may pass through the DC Area on Thursday setting up the stage for well above normal temperatures on Friday! As a ridge of high pressure builds over the Mid-Atlantic, temperatures may reach the middle to upper 80s on Friday afternoon!
Mothers Day Weekend:
The forecast becomes tricky this far out, but the general consensus is that the next frontal boundary may approach the Washington Region from the Midwest on Mother’s Day weekend.
Depending upon exactly when the front passes through, scattered thunderstorms are possible on Mother’s Day with temperatures in the 70s.
April 2014 ranked the 5th wettest April on record at Washington National Airport (DCA) with two-day rainfall totals (April 29th – 30th) running 3.91 inches.
