Tomorrow: Mostly sunny. Highs: 88-92. Forecast in detail Typical midsummer heat and humidity greet our Independence Day holiday; however, the combination is a little less intense than yesterday before increasing again later this week. As a frontal system stalls over the region this weekend, mugginess increases as do thunderstorm chances, but temperatures should pull back some.

No severe, sustained heat is expected anytime soon.

Today (Fourth of July): Skies are mostly sunny as highs work into the warm to hot upper 80s to low 90s. Watch for late afternoon to evening widely scattered showers and thunderstorms but most areas should stay dry. Light winds blow from the west at 5 to 10 mph, except gusty around any storms. While moderately muggy, this is some improvement from yesterday with afternoon dew points in the upper 60s (compared to 70s). Confidence: Medium-High

Highs range from the upper 80s to low 90s, varying mainly based on the timing of clouds and rain chances. Friday night is mostly cloudy with scattered showers or a thunderstorm with lows ranging in the 70s again. Confidence: Medium

The weekend brings moderate humidity, partly to mostly cloudy skies (some sun at times), and daily chances for thunderstorms.

A shower or storm is also possible Saturday night with mostly cloudy skies as lows range from the upper 60s to mid- 70s. Confidence: Medium
