Tomorrow: Sunny, breezy, building humidity. Highs: 91-95
Typical summer heat without too much humidity is pleasant enough today but things get a lot steamier into the weekend. Add in an approaching cool front and showers and storms are likely to bubble up — especially on Saturday. Headed to the beach? Check out the Beachcast at the end of this forecast.

Tomorrow (Friday): Morning sunshine abounds as humidity heads higher (dew points climb to near 70). Breezes from the southwest at 5 to 10 mph take a slight edge off the mugginess while partial cloud cover offers intermittent shade. Highs top out in the low-to-mid 90s on July’s first day. Confidence: Medium-High
Tomorrow night: It is possible that a few thunderstorms could pop up west of the city late in the day and could hold together long enough to briefly dampen a few spots as they progress east. Most areas should stay dry though as lows settle in the low-to-mid 70s. Confidence: Medium
Heat and humidity are givens on Saturday. When thunderstorms arrive in the area is a little bit more guesswork this far out, but probably most activity holds off until late in the afternoon into the evening. Although widespread severe storms aren’t terribly likely, lightning and heavy downpours are possible. Highs should be in the upper 80s to lower 90s and overnight lows are mainly lower 70s. Confidence: Medium
Sunday is tricky. If the cool front pushes in strongly enough most showers stay south of the city. But if the front stalls out, then showers and storms could pop up yet again, especially in the afternoon. Highs should be in the mid-to-upper 80s, but humidity is still on the higher side. Overnight, any showers fade away and lows slip to the mid-to-upper 60s. Confidence: Low-Medium
Skies are partly sunny for the Fourth of July (Monday) and, with a little luck, the fireworks on the Mall will not be disturbed by passing storms. While rain is unlikely, we can’t totally rule an isolated shower or thunderstorm. Highs creep up to the upper 80s to lower 90s so dress cool! Confidence: Low-Medium
N.J./Del./Md. beaches: Plenty of sunshine all weekend. Highs are in the low-to-mid 80s, with lows upper 60s to lower 70s. Thunderstorms are likely Saturday afternoon and evening and isolated Sunday-Monday. Water temperatures near 70, with waves 1-3 feet.
Va./N.C. beaches: Mainly sunny all weekend. Highs reach the mid-to-upper 80s, with lows in the low-to-mid 70s. Isolated afternoon and evening storms are possible each day. Water temperatures are in the low-to-mid 70s near Virginia Beach and in the upper 70s along the North Carolina Outer Banks, with waves 1-3 feet.
