Baltimore residents can expect a mix of stormy skies and sweltering heat over the next few days. According to the National Weather Service Baltimore MD/Washington DC, a stalled front overhead this morning is set to dissipate by the end of the day, but not without leaving a trail of thunderstorms and potential flash flooding in its wake. The weather service advises staying vigilant, as showers and thunderstorms are expected to persist, with the potential for severe weather characterized by damaging wind gusts from wet downbursts. Highs today will range in the comfortable 80s to low 90s, a relative calm before the heat intensifies later this week.

Thursday is expected to be the warmest day of the week, with high temperatures reaching the upper 80s to mid-90s. Finding relief in the shade will be essential, as high humidity pushes heat indices into potentially dangerous territory. The region braces for the possibility of heat indices briefly topping the 105-degree mark, particularly in areas east of I-95, which could have significant impacts on vulnerable communities. As Friday approaches, another cold front is expected to arrive, bringing increased shower and thunderstorm activity. With the front stalling over the area, residents should prepare for a wetter end to the workweek. High temperatures are expected to be in the 80s to 90s on Friday.

Looking further ahead, the weekend forecast spells out a mixed bag of dry spells and thunderstorm risks. Saturday may offer a respite for those east of the Blue Ridge, with isolated showers at most. At the same time, areas west are forewarned of scattered showers and potential thunderstorms in the afternoon and evening. Sunday ratchets up the humidity and storm risks as a warm front arrives, boosting daytime highs to the lower 90s. The National Weather Service forecasts more widespread showers and thunderstorms from midday Sunday through the evening.

Aviation and marine operations should take heed of this week's weather fluctuations. While VFR conditions may prevail on Saturday, both sectors could encounter MVFR conditions due to showers and thunderstorms on Sunday. Boaters are especially advised to watch for possible Special Marine Warnings with thunderstorms along the advancing warm front. According to the National Weather Service, winds will generally sway from light and variable to southwest at about 10 knots by Sunday evening, with sudden increases in select stormy conditions. Fluctuating winds can cause elevated tidal anomalies in coastal areas, yet the risk of extensive tidal flooding remains minimal, sparing commuters and coastal residents from additional weather-induced challenges.
