The National Weather Service in Baltimore, MD/Washington, DC, has announced a weather shift. A cold front is set to traverse the region starting this morning and continuing into the evening. High pressure is predicted to settle in shortly thereafter, bringing with it drier and cooler conditions over the weekend. The front will then move offshore next week. The forecast also hints at another cold front poised to arrive around midweek.
Today's weather will likely experience lingering rain into the afternoon, especially along the Alleghenies this morning, with the eastern areas possibly getting a sprinkle later in the day. According to the National Weather Service, despite incoming measurable precipitation to the west (0.01 in!), east of the mountains may see little to none. Temperatures, which are expected to dip today, might still hit the upper 70s or near 80 along and east of I-81 before the full impact of the cold front hits. The evening will usher in cooler overnight lows, dropping into the 30s to 40s.
Looking forward to the weekend, high pressure will build to the north, bringing maximum temperatures between the 50s and 60s. Saturday's northerly winds will shift to an easterly, then southeasterly direction by Sunday as the high pressure slides east. The overnight warmth will remain on Sunday night as a warm front approaches from the north, increasing dewpoints and maintaining temperatures in the 40s to low 50s. Precipitation chances will similarly increase in Maryland's western and north-central areas with the arrival of the warm front, although recent trends suggest a drier outcome.
Regarding aviation, VFR conditions are anticipated throughout the weekend despite the cold front. There may be a passing shower, but it is unlikely to cause any significant disruptions to air travel. Winds will remain lively today, gusting to 20-25 knots in the afternoon and slackening overnight, but gusts around 15 knots could linger at metro terminals. As for maritime conditions, Small Craft Advisories are in effect across various zones until Saturday, as detailed by the National Weather Service.
