Baltimore residents can expect a relatively peaceful weather pattern heading into the new week, according to the National Weather Service Baltimore MD/Washington DC. As per their latest forecast, a robust area of high pressure settled over the northeast CONUS is slated to shift offshore early next week, with high pressure weakening and a new front slowly approaching from the south. The National Weather Service explains that for today, after morning fog clears west of the Blue Ridge Mountains, skies should open up, with "mostly clear and cool" conditions tonight and lows dipping into the 50s.
The outlook through Monday night stays calm and collected under high pressure. Daytime heating might prompt the development of a broken stratocumulus field in the afternoons, which is expected to clear up at night. The start of the workweek shows a slight uptick in warmth thanks to the sunshine, yet it will remain below normal for early August, according to the weather service.
Looking ahead from Tuesday through Friday, a 1022-1024mb high pressure will persist down the eastern side of the Appalachians, maintaining cool temperatures and low humidity. Highs will reach the mid to upper 80s to the east of the Alleghenies with slightly higher dewpoints as the high pressure weakens. By midweek, rainfall chances climb as Gulf moisture is funneled northward into the area, increasing the likelihood of showers and thunderstorms, particularly over mountainous regions during the heat of the day.
Aviation conditions will remain predominantly VFR, with some afternoon reductions in visibility where those showers and thunderstorms are predicted. Marine conditions should be relatively smooth with sub-SCA level winds and no significant marine hazards expected through Wednesday, as highlighted by the official report.
Residents in Anne Arundel County should take note, as a Coastal Flood Advisory may be in order later today. Onshore winds this weekend could increase tidal anomalies, potentially leading to minor flood stages at sensitive sites like Annapolis. These anomalies may push waters up the tidal Potomac River Sunday into Monday, possibly bringing those sites close to minor flood stages. Stay informed on the latest weather updates to keep ahead of any potential impacts.
