357 AM EDT Mon Jun 23 2025
MARINE
Wind gusts up to around 10 to 15 knots are possible early this morning over the more southern waters. However, expect these to stay below advisory thresholds. Otherwise, gradients remain on the weaker side with a strong ridge aloft. Overall wind fields through mid-week should yield gusts to around 5 to 10 knots. Although wind directions will be variable at times, the prevailing direction should be out of the northwest. Some storm chances emerge by Wednesday afternoon/evening which could impact portions of the waterways.
Winds remain light through the end of this week. Still, mariners should be mindful for any isolated strong afternoon and evening thunderstorms may pop up, and bring an attendant threat of gusty winds and lightning.
TIDES/COASTAL FLOODING
Current tidal anomalies are sitting between 0.25 to 0.50 feet. This is keeping water levels slightly elevated for the more sensitive tidal sites. At this point, only Fort McHenry and Annapolis are slated to reach Action stage during the next couple of astronomical high tides. Expect the shift to northwesterly winds to lower anomalies over the next day or two.

NEAR TERM
…A warm and humid start to the day will give way to near record breaking heat today as a strong upper ridge is parked overhead…Pronounced subsidence under this dome of warm air aloft will generally squash most cloud development. However, like previous days, a fair weather cumulus field likely bubbles up given the degree of heat and humidity at the surface.
A mixture of Extreme Heat Warnings and Heat Advisories are in place over the region today from 11 AM until 9 PM. Generally speaking, these heat-related warnings cover the northern Shenandoah Valley eastward into the D.C. and Baltimore metros, while stretching south along I-95 and over southern Maryland. Heat Advisories span central Virginia Piedmont back into the central Shenandoah Valley and points westward. Higher elevations remain out of any such heat headline. The combination of heat and humidity will raise heat indices into the 100 to 110 degree range.
…Little to no relief is expected into tonight as winds become nearly calm. A warm and humid air mass will hold low temperatures well into the 70s, with low 80s across D.C. and Baltimore. Elevated humidity levels keep heat indices in the 80s to near 90 degrees in the warm spots. The potential for heat illnesses will continue in this environment.
