FORECAST IN DETAIL

We’ve got another beauty of a day today before the forecast starts to get fuzzy. Rain chances and humidity gradually trend higher tomorrow through Friday, and we may even see the remnants of a tropical system move through or close by with a heavier dose of rain late Friday. A stalled front tries to keep us from completely clearing out over the weekend, though shower chances should start to trend lower.

Today (Wednesday): Doesn’t get much better in June. The humidity remains in check and highs head for near 80 to the low 80s, right in the comfort zone for many of us. Throw in partly to mostly sunny skies and light winds, around 5-10 mph from the southeast, and we’ve got ourselves a winner. Confidence: Medium-High

Tonight: Skies turn partly to mostly cloudy as high pressure begins to lose its grip on our area. Overnight lows end up from near 60 to the low 60s and we pick up a 20% chance of a shower toward morning. Confidence: Medium-High

Tomorrow (Thursday): Partly to mostly cloudy skies persist on Thursday as the humidity ticks upward, though it’s still not overly muggy, and highs max out near 80. Shower and thunderstorm chances increase as well, but for now only to about 30% as much of the activity may try to stay west toward and over the mountains. Confidence: Medium

Tomorrow night: The amount of moisture in the air continues to increase and shower chances rise as well, to around 50%. The higher humidity and cloudy skies lead to a warmer night with lows in the mid-to-upper 60s. Confidence: Medium

A LOOK AHEAD

By Friday the humidity is in full effect as highs climb toward the upper 70s to low 80s with plenty of clouds. Looks like a 50-60% chance of run-of-the-mill type showers and perhaps a thunderstorm, but also the chance of a slug of heavier tropical rainfall passing through or just to the east during the afternoon and/or night. Friday night lows bottom in the mid-60s to near 70. Confidence: Low-Medium

Looking ahead to the weekend, a stalled front nearby and a continued moist flow from the south means we’ll have to keep a 30-40% chance of isolated to scattered showers and thunderstorms in the forecast through Saturday and Sunday. Highs should reach at least the low 80s accompanied by moderate humidity. Saturday night lows settle in the 60s. Confidence: Low-Medium
