Confidence: High Tomorrow night: Partly cloudy, a bit muggier, and we can’t rule out the chance of a roving overnight thunderstorm as a weak frontal system heads back northward again. Lows range through the 70s. Confidence: Medium-high A LOOK AHEAD Thursday brings back a bit more heat and humidity with moderate to high dew points along with highs the middle 90s. The one saving grace is a higher chance of thunderstorms in the afternoon throughout the area that could curtail the peak heat. Some storms could deliver some heavy downpours in this tropical air mass. Scattered thunderstorms continue Thursday night with lows in the 70s again. Confidence: Medium Friday looks hot and muggy again with highs in the low to middle 90s. We run the chance for some more thunderstorms depending on the location of a lifting frontal boundary. Friday night looks warm and humid again with lows in the 70s and a few showers or storms possible. Confidence: Medium The weekend may not be quite as hot, but it may come at the price of more showers and storms. We’ll aim for partly cloudy skies, daily (and nightly) chances of showers and storms with highs in the upper 80s to low 90s. Humidity remains moderately uncomfortable still. Lows Saturday night should be in the 70s, but some outer suburbs may manage some upper 60s. Confidence: Low-medium |
