Baltimore's looking at a stretch of sunny, crisp days ahead, according to the National Weather Service Baltimore MD/Washington DC. As high pressure builds in from the west today and settles north of the area by mid-week, temperatures will uphold a cooler-than-usual trend with a dry cold front on Thursday reinforcing these below-normal conditions. This high-pressure system is expected to bring a return to calmer, drier weather as we head into the weekend.
After a chilly night with lows in the 40s and 50s and even dropping to mid to upper 30s in parts of the Allegheny Mountains, where a Frost Advisory was in place until 8 AM this morning according to the National Weather Service, daytime highs are expected to bounce back to the mid 70s, or 60s if you're mountain-bound. The skies will mostly be generous with their sunshine—aside from the odd afternoon cloud waving through.
Moving into the short term, from Tuesday through Wednesday night, high pressure will continue to be a weather-maker to our north, leading to a consistent pattern of below-normal temperatures and limited chances of showers. The offshore low pressure might toss a wave of clouds across I-95 on Tuesday, but for all intents and purposes, there's little to no expectation of rain.
For the latter part of the week, a dry cold front on Thursday sets the stage for sunny skies and high temperatures peaking into the upper 70s to low 80s, a soothing nudge from the cooler days preceding; meanwhile the secondary cold front destined for Thursday could mean that along with towards the weekend the winds will churn a bit, making for some refreshing if not brisk afternoons, and by night temperatures could plunge as low as the upper 40s to 50s, especially along the Allegheny Front.
Aviation-wise, it's smooth sailing with VFR conditions expected throughout the week. The local mariners, however, will need to heed the prolonged Small Craft Advisories flagged by the National Weather Service, running currently through Tuesday morning as northerly winds hold their ground. Coastal areas might see slightly elevated tides, but no minor flooding is forecasted even with the recent full moon working the gravitational tides.
