Baltimore's got a clear, albeit frosty, greeting this Monday morning as high pressure made itself right at home over the city. But the comfort of blue skies will be short-lived, per the National Weather Service Baltimore MD/Washington DC. Forecasters are predicting a seasonably temperate day, topping out in the 40s, with clouds stealing the scene by afternoon.
But Baltimore's weather story is all about change; that wayward low pressure moving toward our Great Lakes neighbors to the north tonight sparks a shift. It looks like we've got some precipitation on tap, maybe starting with snow or sleet, but flipping to rain as Tuesday rolls in and temperatures rise. Given the previous afternoon highs in the 40s and marginal overnight temperatures, any impacts from wintry precipitation would likely be limited, the forecast discussion explains.
Into the midweek, the drama dies down a bit. High pressure takes the lead again on Wednesday, promising calmer skies, though a few stubborn clouds may linger. This reprieve comes ahead of more question marks Wednesday night. Forecasters are looking for the next rainmaker, though they’re keeping the wintry mix talk off the table for most parts as conditions stay mild.
Leading into the Christmas holiday, Baltimoreans might just favor lighter jackets over thick woolens. The mercury could climb a good 10-15 degrees above the seasonal mean, giving us more of an autumn vibe. For Christmas Day, expect cloudy to mostly cloudy skies with a few passing showers during the front half of the day as the warm front slowly pushes through, according to the weather service discussion. These puddle-makers could stick around Friday with one eye to the west, where the Blue Ridge folks might see more persistent rain.
AVIATION enthusiasts can anticipate straightforward flying weather today, with VFR conditions expected. Those high-pressure conditions will keep things easy—barring any light precipitation that might sneak into the region tonight or Tuesday morning, possibly starting as a wintry soup before morphing into rain. But don't expect any significant snow; nothing much looks to accumulate. By Wednesday, it’s clear skies again for air traffic, but already eyeballing Wednesday night as conditions may shift.
Mariners get a similar mixed bag. The high pressure that's been keeping things steady leaves room for southerly winds later today, then another Small Craft Advisory kicks in for the Chesapeake and lower Potomac as the night deepens. Keeps those life jackets handy, because while Tuesday calms a bit, Wednesday could whip up more blustery conditions before a southern breeze slips back in by week’s end.
