The National Weather Service Baltimore MD/Washington DC has announced a hot and potentially stormy forecast for the Mid-Atlantic region. Today, Baltimore residents can expect high pressure to bring dry and hot conditions with temperatures reaching the lower to upper 90s and heat indices climbing to the lower 100s. A Heat Advisory is in effect until 8 PM, cautioning those in the Baltimore and D.C. metros and along the I-81 corridor against the heightened risk of heat-related illnesses.
Tomorrow, however, is an entirely different story. A cold front over the Ohio Valley is set to drift easily into the region by Thursday morning, bringing about a shift that carries deep tropical moisture and the likelihood of widespread showers and strong to severe thunderstorms. According to the National Weather Service, "Model soundings indicate mean storm motion is going to be slow, at or less than 10 knots," which suggests a risk for impactful flash flooding with rainfall rates that could reach 1-2" in 30 minutes.
With the cold front lingering, Friday will also be marked by persisting showers and potential for sub-VFR conditions, impacting visibility and potentially disrupting air travel. During this time, gusty winds and torrential downpours are expected to present periodic challenges throughout the area.
Respite is on the horizon for the weekend, as strong high pressure is forecast to usher in cooler, below-normal temperatures and much less humidity starting Saturday, a notably stark contrast to this week's scorching heat. This will provide prime conditions and an opportunity for the region to dry out after the anticipated storms. Meanwhile, mariners on the water today and Thursday should remain alert to possible gusty winds and lightning strikes, with Small Craft Advisories likely to go into effect on Friday due to northerly winds gusting 15 to 20 knots over the waters.
Coastal regions should anticipate a slight rise in tide anomalies due to the southerly wind direction through mid-week, although no minor flood stages are expected. Even so, caution should be exercised around sensitive tidal locations that may reach Action Stage during high tides. For the full forecast details and any updates on advisories, locals should refer to the National Weather Service website.
