Baltimore's outlook is overcast with a chance of showers, but the warm front on Saturday may brighten things up a bit. According to the National Weather Service Baltimore MD/Washington DC, a nearly stationary front will linger around the Mid Atlantic until Friday night, then shimmy back north as a warm front for the weekend. This Columbia-Snake River shuffle of weather patterns is set to bring a stronger cold front through the area on Sunday.
The Baltimore-Washington metro is currently blanketed in stratus clouds, which have ventured in from the Atlantic, and whether those clouds stick around will be key for today's temperatures, which could hover in the lower to mid-50s. But not all of Maryland will need to keep the sweaters handy, as the National Weather Service predicts, "Places in the Potomac Highlands, central Shenandoah Valley, and central Virginia will see the most sun with highs in the upper 60s to lower 70s." A few rogue showers might crash the party west of I-81, courtesy of a subtle atmospheric wave passing through.
By tonight, expect the stratus clouds to be snug over much of the area, possibly setting the stage for some fog in the southern regions as lows dip into the upper 30s to mid-40s. The weekend should bring a warm-up, but with it, mostly cloudy skies and a chance of showers, especially by Saturday night when the low-level jet kicks into high gear.
Looking towards Sunday, it's shaping to be a classic, sidestepping a potent low pressure as it sashays from the Great Lakes off to the east. The local forecast area can expect quite a gallop in temperature, with highs reaching between the upper 60s to mid-70s, though the higher elevations will likely miss out on the warmth, staying put in the 50s. The National Weather Service stated, "Increased winds combined with moisture advection will lead to increased precipitation chances along with a threat for thunderstorms."
As the week begins, a cooling trend is on the agenda, with the high pressure building from the west promising drier, sunnier times ahead. By mid-week, temperatures are forecasted to climb again, hitting the mid- to upper 70s. In the meantime, those out on the water should be wary this weekend, as the combination of a lurking cold front and strong southerly flow may require SCA conditions or even gale-force wind advisories to be issued.
