Heat advisories may become the soundtracks of our midweek hustle as Baltimore braces for a surge in temperatures, with the mercury poised to punch through the upper 90s. According to the National Weather Service Baltimore MD/Washington DC, the city will be under a warm front that's scheduled to graze the region from Wednesday. Before this steamy interlude, residents will navigate through a veil of patchy fog, which is expected to clear as the day rolls forward.
In an aerial ballet, a stalled cold front will hoist northward on Wednesday after playing limbo over the region today. The resultant humidity, paired with an admirably persistent ridge of warm air, foreshadows a spike in heat indices that could graze the uncomfortable threshold of 100 degrees. Forecast discussions released by the National Weather Service highlight the likelihood of diurnally driven showers and thunderstorms, particularly on Wednesday, which is expected to be the more active day of the impending period. These storms, amid scant steering flow, have the potential to linger and dump heavy rain on the area.
Further inspiring concern for soggy basement owners and street parkers, the Weather Prediction Center has announced a slight risk for excessive rainfall across portions of the area. Navigating through foggy mornings and sultry afternoons, the city will plunge into balmy nights, with overnight lows loitering in the warm embrace of the 70s.
Transitioning into the weekend, the National Weather Service predicts that the weather will remain unpredictable, with a cold front bringing the possibility of showers on Friday, before yielding to a high-pressure system that promises a brief reprieve from precipitation later in the weekend. Unfortunately, draped in moisture, high pressure is only expected to cling through Sunday before a warm front could trigger additional showers or thunderstorms during Sunday's most sweltering hours.
For mariners plotting a course through the Chesapeake Bay or the Potomac River, vigilance is the watchword. The prospect of scattered thunderstorm development entails potential marine warnings, which could pulse out warnings for stronger gusts and choppy conditions. The normal symphony of southerly winds is on the playbill, although an intermezzo of northeasterly breeze may offer some variability Saturday night.
While no coastal flooding is imminent, the National Weather Service advises that persistent southeasterly winds could elevate tidal anomalies, pushing most tidal locations to the brink of their action stages. Sensitive locales like Annapolis, however, are expected to experience minor flooding just below the threshold during the highest astronomical tides.
