The National Weather Service, Baltimore, MD/Washington, DC, has released an area forecast discussion highlighting key weather patterns for Baltimore and its surrounding regions, indicating that we are in for quite a dynamic series of days ahead.
Starting, the weather scenario sets the stage with a low-pressure system taking a northeast turn across interior New England, dragging a cold front through the locale this afternoon and into the evening while we bid adieu to Canadian high pressure by Sunday—nudging offshore and handing the baton to another frontal system that promises to stir the pot mid-next week. This multi-act play of atmospheric forces will culminate in a Friday movement through the area, according to a report by the National Weather Service.
Today's warmth and moisture paint a ripe backdrop for scattered showers and potential thunderstorms especially east of U.S. 15, where up to 1,000 J/kg of surface-based CAPE could be in play, the vertical shear profiles, however, stay in a somewhat marginal range of 25 to 30 knots in the 0-6 km layer, posing the possibility of at least an isolated severe thunderstorm or two with a threat primarily encompassing damaging wind gusts and perhaps a rogue severe hailstone. As the sun sets, Mother Nature's fireworks are expected to simmer down, bringing the tempest to a close shortly after darkness blankets the area.
Temperatures are slated to soar into the mid-70s to low 80s before the cold front crashes the party, triggering showers and storms. It also ushers in a chill with the winds shifting to gusty westerlies, with anticipated gusts ranging from 25 to 30 mph. Those residing on higher terrain might witness gusts that could ramp up to 35 mph. The cold air influx in the aftermath is projected to pull overnight temperatures down into the lower 40s, and the mountain zones could see thermometers flirting with the mid-to-upper 30s.
Looming over Sunday into Monday, the gustiness persists but gradually shifts from a westerly to a northwesterly direction; the Canadian high pressure system moving in will bring slightly cooler temperatures, with Baltimore anticipating sunnier skies and a slight chill in the air, with highs expected in the mid-60s to low-70s. As the high pressure eases off into the Atlantic on Monday, a southerly flow returns, elevating temperatures back up into the low to mid 70s under a serene, sunny sky, giving an encore of fine weather before the next performance of showers potentially encroaches by mid-week.
