Baltimore residents can expect a shift in weather conditions starting today and progressing through the weekend, as outlined by the National Weather Service Baltimore MD/Washington DC. According to their latest Area Forecast Discussion, high pressure from eastern Canada is set to bring a stretch of cool, dry weather following a cold front on Tuesday night. But before we don the sweaters, there will be some minor precipitation to deal with.
Today's weather will be marked by overcast skies, and thanks to an approaching upper-level trough from the southwest, those high-level clouds will only get denser as the day progresses. Baltimore might see some light rain tonight, extending into Tuesday morning, particularly on the south end near Charlottesville, where up to half an inch could fall. Moisture being drawn northward ahead of Imelda will begin to interact with an upper-level trough to our west to bring light rain tonight, the forecast, with slightly higher rainfall expected to the south.
Tuesday is expected to give Baltimore a brief window of rain as remnants of Imelda pull away by afternoon, while the following cold front ushers in cooler air. This will set the stage for a noticeable drop in temperatures midweek, which should last through Friday.
Looking ahead, the long-term forecast from Thursday to Sunday remains consistent and dry, with strong Canadian high pressure keeping the area pleasantly clear. An upper-level ridge will keep the jet stream far north of Baltimore, confirming a spell of weather that favors cozy nights and brisk mornings. Temperatures during this period will stay below normal on Thursday and Friday, and a slight warm-up is expected over the weekend as the high-pressure ridge shifts eastward.
For those concerned about air travel, the weather shouldn't cause any significant disruptions. High clouds and light rain may present themselves, but "no flight restrictions expected," said the National Weather Service. Come Tuesday night, the aviation report projects stronger northerly winds alongside the cold front but remains clear for the latter half of the week.
Marine conditions will be a bit choppier, especially for mariners venturing out Tuesday through Thursday, as the pressure gradient tightens thanks to Imelda's passing and the incoming high pressure. The National Weather Service anticipates Small Craft Advisory conditions beginning Tuesday and lingering into Thursday, with winds easing by Friday when high pressure settles in directly overhead.
