Baltimore residents are braced for a heatwave as the National Weather Service reports persistent very warm conditions leading up to the weekend. According to the Area Forecast Discussion, high pressure will keep the area mostly dry through Wednesday, with high temperatures expected to soar into the low to mid-90s. The central Appalachians and central Shenandoah Valley may see some isolated showers or thunder this afternoon.
As midweek approaches, a cold front set to move through Baltimore is expected to shift the weather dynamics significantly. Conditions remain dry on Tuesday with surface high pressure continuing to build to the south, according to the National Weather Service. Notably, humidity is expected to increase, resulting in heat indices between 100°F and 105°F at lower elevations. This factor should not be taken lightly, given the urban heat island effect prevalent in cityscapes. Those venturing out may want to prepare for a sweltering Tuesday and Wednesday as temperatures could nudge even higher.
Baltimore's weather narrative takes a stormy turn as the anticipated cold front draws close, stirring up the potential for severe weather. "The possibility of strong to severe thunderstorms could arise due to the heat and high humidity fueling them, as well as the possibility of heavy rainfall that could lead to localized flooding," cautions the National Weather Service. Travelers might want to keep an eye on updates as the weather predicament intensifies towards the week's end.
Aviation is also poised to encounter disruptions, with spotty turbulence expected to hit the terminals by Wednesday night. "Multiple rounds of showers and thunderstorms are looking likely. Expect periods of restrictions across all terminals on Thursday," the National Weather Service warns. Mariner activity will not be spared, as gusty winds from brewing storms pose risks midweek, and Small Craft Advisories could go into effect come Friday in the wake of the passing cold front.
Tides around Baltimore's waterfront will remain high and may reach 'Action Stage' during high tide cycles through mid-week. While no minor coastal flooding is currently forecasted, the National Weather Service urges vigilance for those frequenting sensitive tidal zones. Residents and visitors alike are advised to stay informed about local weather updates and take necessary precautions against the various weather risks.
