For those residing or commuting through Baltimore, the recent update from the National Weather Service should shed some light on the expected weather conditions through the coming weekend. The National Weather Service's Baltimore MD/Washington DC forecast, issued at 3:59 AM EST on December 26, anticipates "high pressure over northern New England" that will continue dominating through the early weekend. "A cool air wedge" stays its course along the East Coast into the Mid-Atlantic, leading to a weather scene later on.
Early morning drivers might face reduced visibility, dropping to around 4 to 6 statute miles at times, particularly over the Shenandoah Valley, as the National Weather Service notes that moisture is trapped under a radiation inversion. And while the day may begin in the chill with temperatures ranging in the upper 20s to mid-30s, it's expected to climb, although "residual cloud cover" may put a ceiling on warmth, with anticipated highs in the upper 30s to mid-40s.
The shift into the weekend brings a change as the region gears up for wetter conditions. As a transitional day, Friday may see light rain from the south by sundown, with highs still in the mid-upper 40s. As Saturday rolls in, rain is likely to become more persistent and widespread, with a soaking rain overspreading the area during the nighttime hours, as described by the Weather Service. Spots may see lows in the mid to upper 30s, and higher elevations could catch a brief mix of wintry precipitation.
Looking toward Sunday, the forecast anticipates a powerful upper shortwave that will introduce an impressive temperature jump into the 60s ahead of an impending cold front and potentially an intense line of showers. Wind dynamics also come into play. The deep-layer shear will be in the neighborhood of 40 to 50 knots, which the National Weather Service states could indicate gusty conditions amid the predicted thundery weather. For the marine enthusiasts, expect a spike in southerly winds on Sunday, suggesting that Small Craft Advisories may be needed Saturday evening into the night.
Post-weekend, the weather seems to be taking a breather early Monday, with conditions that should dry out, but it shifts back to unsettled as the week progresses. High temperatures are slated to hold steady in the 50s, though the mountain regions may see cooler days in the 40s. Meanwhile, a train of weak upper-level systems promises more variability in the upcoming mid-week atmosphere, with potential implications for aviators and mariners alike. The aviation sector might experience some restrictions on Saturday due to rainfall. At the same time, Sunday's weather brings a chance of sub-VFR conditions, and marine conditions could warrant attention for "Small Craft Advisories" given the active front set to sweep through.
