Forecast in detail

Tonight: Small chance of an isolated shower or rumble, mainly north of DC. Otherwise partly cloudy with lows about 65 to 70. Confidence: Medium-High

Tomorrow (Friday): Can’t rule out a brief morning shower, mainly in the northern half of the region. Partial morning sun gives way to more bubbly clouds in the afternoon with highs in the upper 80s to low 90s. Scattered showers and a few strong storms are possible, mainly after 3 or 4 p.m., with models suggesting the best chance in the southern half of the region. Confidence: Medium-High

Tomorrow night: The chance of a few evening showers and storms may continue to favor southern areas, with some scattered showers area-wide overnight. Moisture levels are up, so temperatures only fall to the upper 60s and lower 70s. Some patches of fog are possible late at night. Confidence: Medium-High

A look ahead

A cold front gets locked up in the region Saturday and Sunday as it dissipates. That means messy sky conditions for us – a mix of clouds and sun – plus at least occasional chances of rain. Some rumbles could be heard, too, especially Sunday. Highs both days are probably in the low and mid-80s. Confidence: Medium

Warming back up next week. At least mid- to upper 80s on Monday, then 90 or above possible by Tuesday. Even hotter starting Wednesday? Looking that way. Confidence: Medium
