The showers and thunderstorms that were fairly widespread yesterday/early last night have pretty much wrapped up now. However, the regional radar as of 4:15 a.m. was still showing a shower and thunderstorm (albeit an isolated cell) on the eastern side of the Chesapeake Bay, near Easton.
Highs will be in the upper 80s this afternoon. Tomorrow and Saturday will be offering a blend of sun and clouds. Some of the global models are now trying to throw a wrench in what had once appeared to be a very nice day on Friday. These models are starting to pick up on an inverted trough of low pressure, which may result in a few showers and thunderstorms on Friday afternoon, especially away from the coastal plain (or, across upstate New York, as well as in western and central Pennsylvania).
During this time frame, a ridge of high pressure is going to be located near the coast of New England, but this pressure trough, expected to be oriented north-south along the spine of the Appalachians, would be a catalyst for a couple of showers and a thunderstorm or two — driven mostly by instability related to daytime heating.
High temperatures will be mostly in the 80s both days, and while there are some new concerns about a shower and thunderstorm popping up — we can at least say something with a high level of confidence >>> EXTREME HEAT, AND HIGHS IN THE UPPER 90S, WILL BE TAKING A LENGTHY VACATION!!!
