Baltimore residents can anticipate a day of mostly sunny skies as a weak area of high pressure drifts eastward today, according to the National Weather Service Baltimore MD/Washington DC. Near normal temperatures and lower humidity levels are set to provide a respite before shower and thunderstorm chances return on Sunday with a cold front. Winds shifting southerly will introduce a slight muggy feel to the air with dew points hovering in the low 60s, a notch up from Friday's more comfortable range.
The arrival of an upper-level trough is expected to prompt a few showers and thunderstorms later this afternoon, especially within close reach of the Alleghenies; however, the NWS mentions the probabilities for rainfall remain on the low side. Highs today will push back into the upper 70s and low 80s, as reported by the National Weather Service, with evening lows dipping into the mid to upper 60s—an early whisper of fall is felt climbing into the higher elevations, with temperatures west of the Blue Ridge possibly not exceeding the 60s.
Sunday's weather narrative hinges on the movements of a Canadian cold front, promising showers and a potential for thunderstorms into the night as it makes its steady encroachment toward the Atlantic. Although the Storm Prediction Center maintains a general outlook without a categorical thunderstorm forecast, it’s suggested that one or two severe storms cannot be entirely dismissed. The front is expected to clear the area by Monday morning, according to the forecast, followed by a slight uptick in wind speeds and a noticeable drop in temperatures heralding the onset of autumn.
No significant marine hazards are projected for mid-week, with northwest winds expected to breeze between 10 to 15 knots from Tuesday through Wednesday night. Meanwhile, a Small Craft Advisory has come into effect this evening due to gusts potentially reaching 15 to 20 knots as the winds transition southerly.
Coastal Flood Advisories extend into the weekend, with Annapolis poised to experience the most substantial effects. A high tide set for early Saturday morning may lead to the most pronounced flooding of the next few days. Residents adjacent to waterways are being cautioned as the tidal anomalies persist, moderated only slightly by light winds before the incoming cold front initiates a more assertive response
