Much of the Eastern region will see some warmer weather. Thursday was about as nice a day as you could ask for during this time of year, featuring lots of sunshine, low humidity and afternoon temperatures that were mostly in the 70. While clouds are expected to become more noticeable both Friday and Saturday (at least when compared to Thursday), the temperature should reach the lower 80s both day. Also, the weather will be rain-free as the main focal point of showers and thunderstorms Friday and night and into Saturday will be on areas surrounding the Great Lakes, the Ohio Valley and both western and central parts of Pennsylvania.
We still believe that even though a spotty shower or two could occur as far east as the Delaware River late on Saturday afternoon, most of the rain this front will be generating should occur from Saturday night into Sunday. Most of our rain should occur between midnight and noon on Sunday along the I-95 corridor– leaving behind lingering clouds but a dry period on Sunday afternoon.
We aren’t quite ready yet to make a guarantee that Sunday afternoon will be rain-free, but it is at least worth mentioning this possibility. That cool front, which will be pushing slowly to the east during the upcoming weekend, should usher in some cooling just in time for the start of fall (the equinox occurs on Sunday afternoon at 4:44 p.m. EDT.) Obviously, the early morning hours around here have been crisp and quite cool lately beneath a large dome of high pressure. So, we’re still going to see many places outside of the larger cities starting off in the 40s early Thursday, but even these locations should encounter a nice recovery Thursday afternoon. With plenty of sunshine again, temperatures should reach the upper 70s Thursday afternoon, and then most places will be returning to the 50s Thursday night.
