Baltimore is bracing for a bout with the elements as the National Weather Service Baltimore MD/Washington DC has issued its latest forecasts, hinting at a tumultuous blend of weather systems ready to sweep through the region. As reported by the National Weather Service, today Marylanders will find themselves stuck under a blanket of clouds with temperatures resting in the 40s for most, though some areas could see the mercury struggling to breach the mid-30s.
High pressure is keeping its grip tight on the region through tonight, but it's a brief respite before a strong frontal system invades late Sunday into Monday, followed closely by another bracing clipper-type system by mid-week, the weather-rhythm indicative of the relentless pulse of nature's grand orchestration. Warmer air teases the central Virginia back across the central Shenandoah Valley into the Potomac Highlands, where temperatures in the 50s are anticipated, while elsewhere the 40s or even mid-30s dominate the scene amid a pervasive northeasterly breeze.
Come Sunday, southerly winds will usher in milder temperatures and rain, sweeping through the region Sunday night into Monday with potential localized rainfall amounting to a quarter inch along the Alleghenies. As the forthcoming system's cold front presses through, the wind is expected to shift sharply, possibly unleashing gusts exceeding 40 to 50 mph, particularly north of I-66/US-50 and along or west of the Blue Ridge Mountains, with 60 mph gusts not out of the question for higher elevations. According to the National Weather Service, high Wind Watches will likely be required for the Alleghenies and possibly the Blue Ridge Mountains, though such advisories are currently pending.
Looking further ahead into the week, a robust low-pressure system will advance northeastward on Tuesday, lugging in brutally cold temperatures that make the 30s feel tropical compared to the teens and 20s projected at higher elevations, with wind chills diving to the single digits above and below zero. Global models signal a significant downslope windstorm event just over the lee of the Alleghenies, with the potential for gusts surpassing 50 knots. This could be a significant event for Garrett, Allegany, Mineral, Grant, Pendleton, and Highland Counties, the National Weather Service cautions.
In the meantime, pilots can expect mostly VFR conditions across the DC metro area this morning, although a few dips into MVFR are not entirely off the table, especially near KIAD. Marine conditions warrant a heads-up, too, as Small Craft Advisories have been put into effect for a swathe of waters thanks to northerly winds that ramp up following a cold front. These advisories extend across all waters and are likely to persist with the approach of a stronger cold front that'll catapult winds into even brisker territories, hinting at gale-force conditions by early next week. The tide charts provide a minor reprieve, with levels dipping in northerly winds through tonight, but these too are set to surge back in southerly flow come Sunday into early Monday, with areas like Annapolis potentially flirting with minor flood thresholds. Caution may be the day's watchword as the city braces for what the skies hold in store.
