Today is a day to spend outside enjoying, especially if you were doing something unfortunate yesterday like working indoors. If you don’t notice much humidity, it could be the last time for a while, as it starts coming back to close the weekend and probably heads up more from there. I think we get through daylight hours Sunday without a ton to worry about rain wise, but we’ll need to watch the timing of a storm system out west as we close in.

Today (Saturday): Our generally beautiful weather continues under mostly sunny skies, though temperatures are a little too close to the high side of the “Nice Day” criteria of 85 to bring it along for the ride. You’ll probably still consider it a nice day though, and a number of spots may hit criteria! Highs are mostly in the mid-80s, or about 82-87 across the broader region. Winds are light from the northwest. Confidence: Medium-High

Tonight: Skies remain mostly clear, and with a last evening sans higher humidity you may see a few extra stars shining down. Temperatures make the upper 50s in cooler suburbs while probably not getting much below the mid-60s downtown. Winds remain light, shifting toward the south or southwest as the night progresses. Confidence: Medium-High

Tomorrow (Sunday): On the whole, this is another day dominated by sun. We may begin to see clouds increase before sunset as a low pressure associated with central U.S. thunderstorm complexes makes its approach. There’s about a 30% chance it gets here during the late day, but it should want to hold off till near or after dark. While highs aren’t much warmer than today, the return of noticeable humidity mixed with afternoon readings mainly in the mid-to-upper 80s will certainly feel a bit more summer-like. Confidence: Medium-High

Tomorrow night: We’re mostly cloudy and run about a 50-60% chance of at least scattered showers and storms. Lean toward some rain being likely, but there’s still a few unknowns on the system’s track. With current timing, the severe weather threat seems fairly low but that’s still subject to change, especially should it manage to work in during the late-day Sunday. Even with the risk of rain, dew points into the 60s will keep lows from falling too far. We might plan on a range of mid-60s to around 70 (downtown). Confidence: Medium

A LOOK AHEAD

Monday features more in the way of clouds than seen over the weekend, and there could be a few showers around as well. With the likelihood of plentiful gray, temperatures should be a bit muted. So, low-to-mid 80s seems about right for now. Humidity is moderate to high though, with no sign of lowering much right away. Confidence: Medium

Clouds want to break more than Monday as we get into Tuesday, yet we may have trouble fully kicking them out of our area. I can’t totally rule out a shower either, but it appears less of a risk than on the day prior. Under this scenario, highs should rise back toward the mid-80s most spots. Confidence: Low-Medium
