NWS Regional Summary - 658 AM EDT FRI JUL 03 2009
This morning's low clouds and fog patches are expected to diminish by mid
morning. Increasing sunshine and high temperatures in the mid to upper 70s
will be the prevailing weather feature today. However, another weather
disturbance located across western Pennsylvania this morning will track east
across the forecast area during the afternoon. Therefore, expect showers and
thunderstorms once again to develop but will be less numerous than yesterday.
The ground is saturated from heavy rainfall during the past couple of days,
any additional heavy rainfall could cause localized flooding of urban and poor
drainage areas. The chance of showers and thunderstorms diminish during this
evening with the loss of daytime heating. Fog patches will likely form again
overnight across some of the sheltered valleys due to saturated ground as well
as on the Cape and islands. Saturday, Independence Day, yet another weather
disturbance approaches from Canada. This disturbance will have limited
moisture to work with so any showers or thunderstorms will be widely scattered
and be confined north of the Massachusetts turnpike. Another low pressure
center will affect southern New England late Saturday into Sunday, bringing
chances for more showers and thunderstorms during the late holiday weekend.
Conditions for the weekend should be better than we have seen lately, warmer
temperatures and periods of sunshine. The general weather pattern may turn a
little drier early next week.
