The National Weather Service Baltimore MD/Washington DC has issued the latest weather forecast for Baltimore, indicating that cooler-than-average conditions will persist today with high pressure driving dry weather. Evening could bring minor coastal flooding to Annapolis due to southerly flow ahead of a cold front, although the situation is expected not to extend to other prone areas. Temperatures are anticipated to be modest with highs ranging in the mid to upper 70s for most regions east of the mountains, which may reach highs in the 60s.
As the cold front moves across the region on Friday, scattered showers may appear, but the coverage is predicted to be hit or miss, providing relief from the dry spell that's been holding steady. Overnight lows tonight are expected to drop into the upper 40s to lower 50s in the mountains, and slightly warmer temperatures are on tap to the east. The high-pressure system will remain dominant through the weekend into early next week, ensuring the continuation of fair weather aside from a passing shower over the central Blue Ridge due to onshore upslope flow.
Aviators can anticipate prevailing VFR conditions through Friday night, marred only by the potential for increased clouds and a passing shower tonight into Friday, according to the forecast discussion. The weekend should maintain VFR conditions as high pressure takes hold, with some possible exceptions of sub-VFR CIGs south of MRB and west of CHO.
Boating conditions could see Small Craft Advisory (SCA) conditions this afternoon through Friday morning as the cold front makes its approach, with another period possible Friday night in the cold front's wake. However, as the weekend unfolds, no marine hazards are expected with more tranquil north to northeast winds set to prevail courtesy of the high-pressure system building from the north. For the latest updates and detailed marine forecasts, mariners should keep a close watch on the National Weather Service's advisories.
