The latest weather report from the National Weather Service paints a picture of fall truly taking hold of Baltimore. High pressure is our visitor, keeping the skies clear and our spirits high—even as we reach for our heavier coats. Temperatures are slated to hit seasonal lows, inspiring Freeze Warnings and Frost Advisories throughout many regions. According to the National Weather Service Baltimore MD/Washington DC report, we're looking at some areas tipping into the 30-degree territory come tonight, particularly to the north and west of I-95.
In what seems like winter's overeager dress rehearsal, the coldest night of the season will herald the need for gardeners to protect tender plants. The National Weather Service has announced a Freeze Warning for the Alleghenies, Potomac Highlands, and parts of the Shenandoah Valley. Just to the east, a Frost Advisory preps residents for potentially icy windshields and crisp morning lawns in parts of northern Maryland and a handful of counties in the Virginia Piedmont.
Looking beyond the immediate chill, a coastal low is developing off the Southeast US coast, ready to take a northward trip up the Eastern Seaboard. This atmospheric tango is set to bring our weekend weather outlook into high-stakes jeopardy. Uncertainty abounds, as the National Weather Service's forecast discussion mentions, a very delicate interaction between the coastal low and an upper low drifting southeastward. The upshot? A potential uptick in showers and gusty winds comes Saturday afternoon, but don't put your chips down on any specific outcome just yet—the forecast models are still hashing out their disagreements.
Boaters should ready themselves for a sustained blow, with a Small Craft Advisory issued until this afternoon and Gale Watches on the horizon. According to the National Weather Service, our waters will witness at least SCA criteria winds and possibly gale-force gusts as the coastal low plays its hand. Not one to be outdone, the wind also brings a bout of coastal flooding into the mix, with Annapolis and other sites bracing for soggy impacts starting Friday, reaching a crescendo by Sunday.
Aviators aren't spared either. VFR conditions will hover around until Friday night, but the brewing coastal low could spoil the clear skies, as noted in the forecast discussion. A cautious eye will be kept on the low track, which will spell out the intensity of our collective turbulence. For now, we can bask, however briskly, in the gold-dappled sunlight that autumn grants—a crisp prelude to the atmospheric performance promised by the weekend.
