Baltimoreans can stash away their summer gear a bit longer as the NWS in Baltimore MD/Washington DC forecasts cooler temperatures and lower humidity through Friday, nudged along by a high-pressure system wedging south from eastern Canada. According to the National Weather Service report, "Broad high pressure over eastern Canada will wedge south into the region through Friday," promising a respite from the heat. The weekend, however, should see a slight return to warmth, with the mercury making its way back to the mid-70s to low 80s.
Today's highs are expected to crest around a mild 70 degrees, with a light northern breeze, while nightfall ushers in lows that could dip into the mid-30s in the most insulated valleys, as the high pressure from Quebec builds southward and nestles over New Jersey by Friday morning. While Thursday may entice a scattered stratocumulus deck as the winds turn onshore, evenings are slated to benefit from good radiational cooling conditions, extending that autumnal feel.
Light winds and daytime stratocu clouds are on the agenda come Friday, maintaining cooler-than-average conditions, particularly noticeable after sunset. Looking ahead to the weekend, as the high-pressure system clings to the New England coast, the area will bask in mostly sunny to partly cloudy skies, a perfect setup for those seeking mellow outdoor plans, as per the weather discussion issued by NWS.
The sailing community can anticipate smooth seas, with no marine hazards looming through early next week—winds are predicted to mellow out and switch from the south on Saturday to southeasterly come Tuesday. However, attention wanders back to the shore where things could get a tad frothy, the threat for widespread minor coastal flooding, and possible moderate coastal flooding at Annapolis could occur during multiple high tide cycles starting late tonight and continuing through Friday, the NWS warns, attributing the potential flooding events largely to the tempestuous snapback of northeasterly winds swinging eastward then southeasterly later in the week.
For aviators, the skies are friendly and clear, with North to Northeast winds easing over the next couple of days, expecting P6SM SKC today and tonight, then scattered stratocumulus Thursday and Friday, ensuring pleasant conditions up until a possible cold front next Tuesday that could stir up some sub-VFR conditions. Overall, Baltimore prepares to wrap itself snugly in the blanket of fall, where one can enjoy crisp days, chillier evenings, and not a snowflake in sight to fret over—yet.
