FORECAST IN DETAIL

Sunshine and slightly lower humidity feature prominently as we close out this not-quite holiday weekend. The takeaway for the next few days is that while we’ll be adding to our 90-degree day count, humidity is merely uncomfortable rather than oppressive. A stalled front could trigger a few thunderstorms for our Fourth of July, but hopefully not enough to cause widespread disruptions.

Today (Sunday): With mostly sunny skies, temperatures head for the low 90s once again. But behind a cold front the humidity drops a touch compared with yesterday, which is nice. There’s just enough instability in this warm and still somewhat humid mass to keep the mention of an isolated thunderstorm in the forecast.  Winds are from the west-northwest about 10 mph. Confidence: Medium-High

Tonight: We’ll hold on to the chance of an isolated evening storm. Otherwise we’re looking at partly cloudy skies through the overnight hours. The moderate humidity is high enough that with little to no wind to move the air, I’ll still call it stuffy. Expect lows in the low to mid-70s downtown, and upper 60s to low 70s elsewhere. Confidence: Medium-High

Tomorrow (Monday): Monday appears to be a repeat performance weather-wise, perhaps slightly hotter. Skies are mostly sunny for most of the day, with highs reaching the low to mid-90s, and the humidity still not terrible. Clouds may bubble up during the heat of the afternoon, with again that chance of a late-day isolated storm, though the best chances should stay northwest of the metro area. Winds are generally from the west and light. Confidence: Medium

Tomorrow night: With a front draped across the region, an isolated storm remains possible. Humidity levels creep up as well, making for a rather sticky night. Skies trend mostly cloudy, with lows in the low to mid-70s. Confidence: Medium

A LOOK AHEAD

Independence Day shapes up as partly sunny, hot, and fairly humid, with a few afternoon or evening thunderstorms possible. Any storms are hopefully hit or miss enough to not cause widespread problems for cookouts, fireworks and the like. But check back as we fine-tune the forecast. Afternoon highs reach the upper 80s to mid-90s, with Tuesday night lows in the low to mid-70s. Confidence: Medium

A little more moisture and lift in the atmosphere on Wednesday may bring a better chance of more numerous showers and storms. While temperatures may trend a bit cooler, with highs aiming for the upper 80s to near 90, humidity is probably on the rise. Confidence: Low-Medium
