Today (Thursday): Early risers are treated to the first of two full moons this month. I prefer the moniker thunder moon for this one. Ironically, this is probably (less than 10 percent chance of storms) the one day in the next few where we won’t have that chance. Look for a few patches of fog to burn off quickly under a bright blue sky. Highs reach the low-to-mid 90s. Humidity is bearable but the lack of a breeze is a bummer. Confidence: High

Tonight: Temperatures slip through the 80s in the evening thanks to just modest mugginess. Winds are lacking. Lows end up in the upper 60s outside the beltway to mid-70s downtown. Confidence: High

Tomorrow (Friday): Look for another mostly sunny day but there is the slimmest of chances (10%) that you might get a brief late day thundershower. Most of us will just see another toasty day with highs mainly in the mid-90s. Humidity climbs a bit as breezes from the south pick up just a bit. Confidence: Medium-High

Tomorrow night: An isolated evening thundershower is still possible but unlikely (10% chance). Readings remain in the 80s until after midnight. Lows end up in the low-to-mid 70s. Confidence: Medium-High


Saturday should be slightly more humid and breezes remain light. Highs should be mainly in the mid-90s. The chance of significant thundershowers remains scant (20%) so don’t fret about hitting the pool or the beach. Just keep an eye out in the afternoon, in case a dash to the car or house is necessary. Evening readings remain in the 80s. Overnight lows only fall to the low-to-mid-70s. Confidence: Medium-High

Sunday is likely to start popping up clouds by mid-day and several of these could build enough to put down thunderstorms during the course of the afternoon. By evening, up to half of the area could see these early storms and one or two could be severe. Highs should still make the low-to-mid 90s in most areas before any rain. Showers and storms are likely at times overnight (60% chance) through the night as a cold front approaches. Lows should be rain-cooled to the upper 60s to lower 70s. Confidence: Low-Medium

Monday is likely to be a backwards day with thundershowers most likely (60% chance) in the morning hours as the cold front pushes through the area. Things may calm down in the afternoon but the proximity of the front could produce lingering storms, especially south of town. If clearing occurs on cue, highs could still make the mid-to-upper 80s. Confidence: Low-Medium
