Quick
Post for this week
Current Surface
Chart and Radar
The surface chart shows the cold front dropping through Pennsylvania, heading for Maryland and Delaware. Behind the front the air is much cooler and less humid than it has been. The cooler drier air will push into the Mid Atlantic today. As it does so, rain showers and thunderstorms will become prevalent. Some of these thunderstorms may become strong to severe, bringing the risk for damaging wind gusts, hail and heavy downpours.
The Storm
Prediction Center has a Marginal Risk for severe storms over extreme southern Maryland.
This cool
down over the region will be short-lived lasting into tomorrow. But then big
changes are going to occur, the jet stream pattern over the eastern U.S. will
shift northward as a big ridge takes over the pattern. Starting Tuesday, the heat and humidity will start
to ramp up. The heat and humidity will continue to build during the rest of the
week. This will be the warmest surge of heat and uncomfortable humidity we’ve
seen so far this year. The first half of
the week should see more dry time than wet time, with many of y’all staying
dry. But rain chances will increase for the rest of the week, as we could see a
moisture plume set up from the Gulf of America.

We’re going to have a tropical high over the Atlantic. The clockwise (or as my grandmother said Deasil) flow around the high will allow for plenty of moisture to stream northward for Thursday and Friday. Both days will likely feature rain showers and thunderstorms, some of these storms could be locally strong to severe.
The Tropics
The National
Hurricane Center isn’t showing anything developing in the Atlantic Basin for
the next 7 days. But this is typical for this time of year, as sea-surface
temperatures aren’t as warm as they will be later in the season, also windshear,
dust and other conditions aren’t as favorable at the start of the season. This time
of year, any development normally occurs in the western Caribbean, Gulf, and
off the Southeast Coast. Conditions could
become a bit more favorable as we head past Flag Day.
