We’re in a bit weather gridlock as moderate to high humidity, slightly hotter-than-normal weather, and frequent storm risks make sure none of us forget what season we are currently enduring.  Some relief edges our way by Friday though as a weak cool front arrives to lower humidity for the weekend and improve our comfort level. But the stubborn front may linger close enough to the area to keep shower/storm threats in the picture.

Today (Tuesday): Mixed sky cover today with scattered morning light showers along with a 40 percent risk of mainly afternoon into early evening showers and storms. Precipitation totals will range broadly from zero/trace to a tenth or quarter inch in most cases. Highs are in the upper 80s to near 90 again with moderate to high humidity (dew points up to about 70F).  Winds from the southwest are mainly 5-10 mph. Confidence: Medium

Tonight: A 30 percent chance of lingering evening storms/showers, but otherwise, partly cloudy, muggy again, with lows in the low to middle 70s.  Light winds from the southwest at around 5 mph continue to pump in the swamp mass.  Confidence: Medium

Tomorrow (Wednesday):  Mixed cloud cover, but essentially partly sunny skies most of the time with a continued 40 percent risk of mainly afternoon to evening showers and storms.  Highs again range in the upper 80s to low 90s with humidity at moderate to high levels (dew points around 70F or in the upper 60s again in the afternoon). Confidence: Medium

Tomorrow night: A continued 30 percent chance of roving showers or storms, mainly in the evening with lows in the low-to-mid 70s as light breezes continue from the southwest.  Confidence: Medium


Thursday has the best chance for more widespread showers and storms (60 percent likelihood) throughout the day with partly to mostly cloudy skies as afternoon highs range from the 80s to around 90.  This may be one of those days where the daytime temperatures fluctuate quite a bit due to cloud cover and precipitation variability.  Thursday night sees a continued risk of showers and storms (40 percent chance) with partly to mostly cloudy skies as lows dip a bit lower into the upper 60s to around 70. Confidence: Medium

Friday should place our area north of a cool front finally, which allows our humidity and dew points to fall (deeper into the 60s) to somewhat more comfortable levels.  The cool front may linger close enough to our south to still trigger some shower risks, so we keep a 20 percent chance in there. Friday night is partly cloudy with lows from the more comfortable middle 60s in the outer suburbs to near 70 in the city.  Confidence: Medium

The weekend should feel generally better with partly sunny skies and low-to-moderate humidity ranges instead as highs generally top out in the mid-to-upper 80s.  There is this risk though that the cool front eases back north into our area, so we have to keep a running 30 percentrisk of storms in the picture.  Lows Saturday night should again get into the 60s in the suburbs, but may stop again around 70 in the city.  Confidence: Low-Medium
