Washington woke up to clear skies Wednesday and a crisp 57°F at Reagan National, with light northwest breezes and good visibility making for an easy commute. The cool start will not last long, though, as the sun takes over and temperatures climb through the afternoon.
Expect mostly sunny skies with a high near 83°F today and a north wind around 5-8 mph. The rest of the week turns steadily hotter: highs near 89°F on Thursday and into the lower 90s by Friday, with some spots eyeing the mid 90s on Saturday. Dew points should linger in the 50s, so the heat index stays close to the actual air temperature and humidity remains on the modest side, according to the National Weather Service.
Weekend Heat Spike
High pressure sliding offshore and an upper-level ridge will help push afternoon highs into the 90s late in the week while most of the area stays dry through Saturday. A cold front is expected to boost shower and thunderstorm chances Sunday into early next week. If the heat index approaches 95°F, the District can activate its Heat Emergency Plan and open cooling centers; residents can find locations and guidance through the D.C. Department of Parks and Recreation.
Tides And Coastal Flooding
The early-morning high tide cycle has Annapolis flirting with minor coastal flooding, and a Coastal Flood Advisory for parts of the bay (MDZ014) remains in effect through 9 a.m. this morning, according to the National Weather Service. Expect nuisance flooding at marinas, waterfront trails and low-lying roads, and avoid driving through standing water. Mariners and waterfront businesses should keep an eye on conditions before heading out.
What To Expect
Mostly sunny skies and comfortable humidity make Wednesday friendly for commuting and outdoor plans, though it is still smart to bring water if you will be outside for long stretches. Shower and thunderstorm chances go up by Sunday, so keep a backup plan in mind for late-weekend events. Mariners should also watch for the potential of Small Craft Advisories late Saturday into Sunday.
