Baltimore residents can break from the heat this weekend as the National Weather Service Baltimore MD/Washington DC predicts below-normal temperatures and dropping humidity levels, bringing some respite from the usual August swelter. The forecast comes as a strong high-pressure system is slated to make itself at home over the region, giving way to cooler, more September-like weather—a welcome shift after what can typically be harsh summer conditions in Charm City.
Today, the city sits under a low cloud overcast just north of a frontal zone with the potential for isolated showers in the north and scattered to numerous showers west of the Blue Ridge, due to an upper trough dragging across the Northeast and Mid-Atlantic states; it will feel significantly cooler with high temperatures meandering in the mid-70s and a noticeable northerly breeze making things feel even more brisk, according to the National Weather Service.
Going into Saturday and Sunday, high pressure will take charge north of Baltimore, cueing fair weather conditions with some cloud cover expected due to trapped low-level moisture, but the sun should make appearances to warm things up a tad, with weekend highs hovering around 80 and nighttime lows dipping into the 50s west of I-95, the weather narrative diverging from the typical early-August script.
Looking ahead to next week, high pressure will hang around on Monday maintaining dry conditions with seasonably cool temperatures and continued low humidity, however, rain chances barge back into the forecast Tuesday onwards as a potent upper-level trough links up with southern stream moisture, meaning low pressure could throw a wet wrench into midweek plans—exact timing remains up in the air, the National Weather Service reports.
For those wondering how this meteorological mood swing might affect air travel, today's gloom brings with it MVFR/IFR conditions and isolated showers, with northerly gusts reaching 20kt, but clearer skies are on their way as the sun sets; aviators should anticipate better visibility over the weekend, with scattered to broken stratocumulus clouds dotting the daylight hours before making an exit at nighttime, staying the course through Tuesday with winds easing off as the high pressure takes a bow off the northeast coast.
Mariners, too, can expect northerly winds to pick up through today, but settle as the weekend rolls in, with conditions pegged to stay below Small Craft Advisory criteria come Monday and Tuesday, featuring a relative lull with light E to ENE breezes gracing the waters, so it seems the seas, like the city, will experience a grace period before the potential tumult of the week's latter half.
