The Baltimore region is bracing for a mixed bag of weather conditions as the National Weather Service (NWS) forecasts a shift in surface high pressure that's been providing relief to the region with dry conditions and seasonable temperatures; however, this respite is set to give way to an approaching frontal system that could lead to increased precipitation towards the end of the week, particularly over the weekend when the cold front is expected to stall, according to the National Weather Service forecast discussion.
Today's weather is likely to stay dry until the evening, but for those living west of the Blue Ridge, the morning may bring a few isolated showers as a disturbance moves across the area, cloudy skies are to be expected as the frontal boundary approaches with the thickest cloud cover situated in the northwestern reaches of the forecast area, setting the stage for overnight showers and thunderstorms, particularly along and west of the Alleghenies, meanwhile, temperature highs are anticipated to linger in the upper 80s to low 90s, with cooler temperatures gracing the higher elevations.
Looking at the short term, Thursday and Friday are primed for scattered to numerous thunderstorms as the front and a pre-frontal trough stall near the region, with conditions ripe for convection and the possibility of heavy rainfall and urban area flooding taking center stage on Thursday; this, coupled with high temperatures in the mid-90s and escalating heat indices due to increased moisture, would make for an uncomfortable concoction of weather phenomena that demands attention and preparation.
The aviation sector is set to encounter potential hiccups, with prevailing VFR conditions expected to deteriorate to sub-VFR amid showers and thunderstorms that roll in with the approaching weather system, where reduced ceiling and visibility, gusty winds, and frequent lightning are probable, the NWS advises caution for mariners as well, with a Small Craft Advisory in place for select areas on Wednesday afternoon into the evening, when gusty winds are likely and thunderstorm activity over the weekend could warrant additional advisories.
According to the NWS, waterways may see some impact from the evolving weather conditions too, with tidal anomalies on a steady uptick, leading to heightened awareness of potential minor coastal flooding particularly in sensitive spots, with the most likely occurrence around Annapolis during Thursday morning's high tide cycle, beyond this immediate concern, trends will be closely monitored throughout the weekend to determine the necessity of Coastal Flood Advisories.
