Baltimore's weather patterns this week seem to convey a message of calm, with the National Weather Service in Baltimore MD/Washington DC outlining a forecast that promises a steady spell of dry and cool conditions. High pressure is the unsung hero of the moment, drifting north and leaving us with below-normal temperatures that seem to manifest nature's own brand of air conditioning through the middle of next week, as reported by the National Weather Service. Today's forecast, specifically, calls for the jet streak's pivoting away and yields skies clearing from northwest to southeast with comfortable highs nestled in the 70s – the 60s if you find yourself in higher elevations.
The nighttime landscape will be lit by the glitter of stars, and if you're planning your evening soirees, expect widespread lows in the 50s while some pockets may even dip into the 40s, as this calm weather pattern extends its stay. While today shows clearing skies, a shortwave trough approaching at dawn may increase those unassuming mid and high level clouds; the serene high pressure will enhance the eastward winds, bringing just enough moisture west of the Blue Ridge for a hint of low clouds.
For those with the weekend wanderlust, the shortwave trough's pivot across the region on Sunday will likely close off into a low Sunday night into Monday—resulting in an inverted trough along the Appalachians, recent guidance suggests the best convergence and moisture will be west of the local crest; the rest of us will watch scattered to broken clouds dance across the sky beneath the trough. Dry weather will continue, as the National Weather Service reports, with a persistence forecast for temperatures Sunday and Monday, as highs will mainly be in the 70s and lows in the 50s.
Looking further out, a blend of high pressure shifting toward the southern New England coast and a cold front stalking east from the Midwest may suggest that Baltimore is poised for its next rainy reprieve; yet the severity of this rain remains a question mark as experts hint at a low threat for severe weather, primarily wind and hail—should it materialize, with the most telling contrast being the drastically cooler airmass behind the front for the upcoming weekend ahead, articulated by the National Weather Service. Still, coolness is the theme of the week, with expectations of mid-week highs in the cozy mid-70s and low-80s, lows delivering autumn whispers in the 50s, and the mountains offering a chillier embrace in the 40s and 50s.
Up in the air, pilots and passengers alike can breathe easy as VFR conditions are projected to continue through Wednesday, courtesy of that stubborn high pressure. Marine activities also set an easy pace with winds staying below Small Craft Advisory criteria until the latter part of the week when south to southeasterly return flows twist the story, and coastal flooding seems to keep its drama at bay with minor concerns slated for late into the week.
