Weather from NBC Storm Team 4 — Updated 6:30 p.m., Aug. 4, 2015

Day 12 of the heat wave (Reagan National made it to 96F at 3:18 p.m.) and it was more humid than previous days. As a result with cold fronts moving through, some strong thunderstorms developed Tuesday afternoon and they’ll be with us scattered around through the evening hours. The main threats from the storms will be hail and damaging winds. Behind these storms and the cold fronts more comfortable, less humid air will move in late tonight and last a couple of days.

Wednesday will still be hot but it will be more comfortable from less humidity, courtesy of high pressure. As that high pressure system moves across New England, a northeasterly flow will develop, breaking the heat wave on Thursday. Then a few waves of low pressure will drift along a stationary front and bring several chances of showers on Friday and possibly Saturday.

REST OF TUESDAY EVENING: Mostly cloudy. Warm and humid. Scattered thunderstorms, some of which could be strong.
Temperatures in the 80s.

OVERNIGHT: Storms ending early, then clearing.
Lows: low 70s.

WEDNESDAY: Mostly sunny and a bit breezy. Less humid and more comfortable, even though it will be hot.
Highs: near 90.

THURSDAY: Increasing clouds. Not as hot. Chance of showers and thunderstorms arriving late in the day.
Highs: mid 80s.

FRIDAY: Cloudy and cooler. Scattered showers and thunderstorms throughout the day.
Highs: low 80s.
