Bracing for a mix of weather in the region, Baltimore and Washington DC can expect scattered showers and potential thunderstorms today, as reported by the National Weather Service. With a dissipating stalled front to the east, skies are set to clear overnight, paving the way for a return of hot conditions, while keeping humidity levels in check.
Looking ahead, Monday and Tuesday will bring a spike in temperatures, with highs possibly reaching the 90s. Despite recent rains, the dry spell that preceded it could lead to temperatures surpassing forecasts, especially in areas west of the Blue Ridge Mountains where wind patterns may play a role. However, modest humidity means heat index values might hover just below official levels of concern. An imminent increase in shower and thunderstorm activity is also on the cards for Tuesday, with some storms potentially packing gusty winds, prompting a Marginal Risk warning by the Storm Prediction Center.
The crossing of Tropical Cyclone Debby through the Carolinas has the potential to impact weather patterns significantly towards the later part of the week, although it is still subject to evolving atmospheric conditions. The National Weather Service states, "specific rain amounts and flooding potential is reliant on the eventual track and placement of Tropical Cyclone Debby." Temperatures during this period may drop slightly below average, offering a respite from the heat due to the increased cloud cover and precipitation anticipated as Debby moves northward.
For aviation, VFR conditions are poised to remain through Tuesday night while sporadic showers and thunderstorms could lead to some disruptions. Meanwhile, local mariners should be on alert for Small Craft Advisories that might be decreed from Wednesday through to the end of the week as a reaction to onshore flow and heightened shower and thunderstorm activity, potentially including Special Marine Warnings as Debby approaches.
