We should stay storm-free through the day today and may even stay dry into or through this evening. Overnight tonight and toward dawn is when the chance of showers and thunderstorms jumps higher, though the exact track, timing and intensity of storms remain in question. By Friday and through much of the weekend, we’re back to pleasant and likely rain-free weather. Temperatures are warm throughout the forecast period with highs mainly in the 80s.

Today (Wednesday): Mostly sunny skies should lift highs to the mid-to-upper 80s. Drying winds from the northwest and west, around 5-10 mph, help keep humidity lower than today, though perhaps still slightly noticeable. Looks like we’ll stay dry at least through the commute home. Confidence: Medium-High

Tonight: The evening brings the possibility of an isolated shower or thunderstorm, but the best chance of showers and storms probably waits until after midnight, when the risk rises to 60%. We could see a strong line of storms come through overnight or toward dawn, though some modeling suggests the strongest storms could miss us to the north. We should have a better idea of the threat and timing by this afternoon. Humidity rises again as lows fall to the mid-60s to near 70 under mostly cloudy skies. Confidence: Low

Tomorrow (Thursday): There’s a 50-60% chance you’ll wake up to showers and thunderstorms in the area, which could slow the morning rush. Shower and thundershower chances decrease later in the morning through afternoon, though may linger around 30% into the afternoon. A cold front moving through by midday shifts our winds to come from the northwest near 10-15 mph with higher gusts, knocking the afternoon humidity back down again as skies see partial clearing and highs hit the low-to-mid 80s. Confidence: Low-Medium

Tomorrow night: Skies turn partly to mostly clear and it’s pleasantly cooler and less humid. Evening temperatures should be quite nice, falling through the 70s and into the 60s late. Overnight lows bottom in the mid-50s to near 60. Confidence: High

A LOOK AHEAD

High pressure locks in overhead Friday and Saturday, providing mostly sunny skies and fairly low humidity. Highs warm to near 80 to the low 80s on Friday, and to the mid-80s on Saturday. Friday night and Saturday night lows range from the mid-50s to low 60s. Confidence: Medium-High

By Sunday, high pressure drifting offshore may allow increasing clouds and humidity. Still, skies should be at least partly sunny and the humidity shouldn’t be horrible with highs in the 80s. For now, can’t rule out an afternoon or evening shower or thunderstorm. Confidence: Medium
