Summer officially arrives...

It feels anti-climatic, but the Summer Solstice is Thursday afternoon at 2:06 P.M. EDT. After yesterday's high of 99, I think Mother Nature has already shown us summer's true colors. This was the highest temperature since August 3rd last year, when we reached 102 degrees (which was a record high for the date). A front that came through the area Wednesday afternoon has brought much more comfortable air to the Mid-Atlantic. The first hours of summer will provide plenty of sunshine, with readings in the 80s and pleasant humidity levels. The humidity will creep back up on Friday as another front slides into the region from the north.

The weekend...

A complex of showers and thunderstorms will likely slide south and east along the front from the Great Lakes Friday afternoon and evening, and could graze the area Friday night. Behind this front, another comfortable air mass will settle in on Saturday. However, this won't last very long, as temperatures should crack the 90-degree mark on Sunday.

Next week...

The new work week will start very hot, with several days well up into the 90s. There are some signs of moisture trying to push north from the Gulf by the middle of the week, and that could eventually introduce some rain chances to our forecast. The upper level pattern looks like it could change a bit by July 1st, so the extreme heat may not last more than a couple of days. Stay tuned for updates...

Tropical update...

We're now 20 days into the Atlantic hurricane season, so I'll be keeping you posted on any potential storm development as we go through the next couple of months. During June and early July, the favorable areas for development are the Gulf and Caribbean. Right now, it's very quiet there and no development is expected over the next several days.

More heat in the wake of the storm...

Barry brought much-needed rain...

Barry's remnants brought more rain to some places on Sunday than had been observed during the entire month of May. Here at the WTVR studios, we recorded 1.45" of rain...and during May, we received 1.71". It was even drier in Northern Virginia, where Dulles airport received only 0.34" of rain in May, the driest on record going back to 1962.

Anyway, Barry was responsible for some impressive rainfall totals up and down the East Coast. Here are the highest totals we've received from various states:

FLORIDA West Palm Beach Int'l Airport 6.99"
GEORGIA Mount Vernon 8.00"
S. CAROLINA Hardeeville 6.12"
N. CAROLINA Fuquay-Varina 3.73"
VIRGINIA Pennington Gap 3.75"
MARYLAND Frostburg 1.75"
PENNSYLVANIA Philadelphia Int'l Airport 1.66"
DELAWARE Dover Air Force Base 1.54"
NEW JERSEY Absecon 4.50"
NEW YORK New York--Central Park 3.91"
CONNECTICUT Berlin 2.90"
MASSACHUSETTS Taunton 3.19"
RHODE ISLAND Burrillville 3.10"
NEW HAMPSHIRE Newmarket 2.75"
MAINE Saco 2.64"

More heat on the way...

Here in Central Virginia, we've got another very warm day on tap for Tuesday. There is the possibility for a few pop-up storms later in the afternoon, as a front approaches from the west. This front will bring a little lower humidity for Wednesday. However, the heat and steamy conditions will return by the end of the week, heading into the weekend. Temperatures will likely climb into the 90s on Friday and could stay above 90 for highs over the weekend. There will be another front approaching the region by the weekend, and that could kick off a few scattered afternoon storms each day. It's typical for fronts to have a hard time getting very far south of here at this time of the year, and this one will be no exception.

Hurricane Season begins!

Barry is here!

The Atlantic hurricane season has officially begun, and we've got a storm out there this weekend. Tropical Storm Barry formed in the eastern Gulf of Mexico late Friday afternoon. The storm saw some brief intensification early Friday evening (with maximum sustained winds of 50 mph), but then convection spread out and no further strengthening is expected. The worst weather is on the east side of the storm, and is affecting Florida with heavy rain and the possibility of isolated tornadoes.

Barry is expected to make landfall along the northern Gulf Coast of Florida Saturday afternoon, then move through the extreme Southeastern U.S. bringing some heavy rain. We expect some of the rain to affect Central Virginia, beginning Sunday morning in our southern counties. The storm should weaken and probably lose its tropical characterisitics before getting this far north, and will pass off the Outer Banks of North Carolina Sunday afternoon and evening. Showers and thunderstorms are expected across the region Sunday, with the heaviest rain occurring east of Interstate 95. West of Metro Richmond, the precipitation will be more scattered in nature.

The coming work week and beyond...

In the wake of the storm, a front arriving from the west could trigger a few afternoon thunderstorms on Monday. This front may hang around on Tuesday as well, but then a drier pattern should set in by Wednesday. An upper level ridge will build east, and that will lead to rising temperatures. We could be reaching 90 or higher by Friday 6/8 and the longer range guidance shows this ridge could be rather dominant the following week, so get used to the heat!
