We’ve had our share of zany weather in recent months, and years really. Now it seems Mother Nature has run out of gas, with this same old weather pattern - partly to mostly cloudy, occasionally showery/stormy, highs mainly in the 70s - poised to stick around a few more days. It’s no guarantee, but there’s an increasing chance she’ll start to mix things up again with a warmer, sunnier and drier weekend.
Today (Wednesday): The weather pattern is complicated, as we talked about yesterday, yet the forecast is relatively easy - same as yesterday. Still under the influence of upper-level low pressure, we continue fairly humid with partly to mostly cloudy skies and the potential (60% chance) for a periodic and possibly heavy shower or thunderstorm, but likely with extended breaks in between. Afternoon highs should manage the mid-70s. Confidence: Medium
Tonight: A periodic shower or storm remains a risk (50% chance) through the night. Could also be some areas of fog and/or mist - otherwise it’s mostly cloudy as lows drop to the upper 50s to low 60s. Confidence: Medium

Tomorrow (Thursday): The beat goes on with mostly cloudy skies and a 50-60% chance of a shower/storm (especially in the afternoon) at any given location. We should be a bit less humid than today with highs aiming for the low-to-mid 70s. Confidence: Medium
Tomorrow night: Shower/storm chances continue but scale back to more like 40-50%. Lows are likely similar to tonight, in the upper 50s to low 60s under partly cloudy skies. Confidence: Low-MediumA LOOK AHEAD
Still reading? Not yet bored out of your mind by the broken-record forecast? Let me try again: Friday brings more shower and storm chances, but down a bit further to around 30-40% with partly to mostly cloudy skies and highs in the mid-to-upper 70s (again, shouldn’t be as humid as recent days). Shower/storm chances continue their gradual decline Friday night to about 20-30% with the usual upper 50s to low 60s for lows. Confidence: Low-Medium
I’m not yet ready to completely dismiss the chance of a pop-up shower or thunderstorm this weekend, but I’d say odds go down to around 20% or less. Skies should be at least partly sunny and we warm up nicely to highs in the upper 70s to mid-80s and not too humid. Confidence: Medium
