Our current weather resembles a weaker version of last week’s brutal heat wave.  Interestingly, last week was also the hottest one of the summer from a 30-year climatology standpoint.  At least for the time being, we don’t see any heat to rival those levels, but today’s temperatures reaching toward the low 90s combined with moderate humidity is still not all that pleasant.

Relief is coming by later this week with nicer weather by Thursday, and perhaps Friday and Saturday too before another cold front approaches with storms on Sunday.

Today (Tuesday): Like Monday, we expect variable sky conditions that are sometimes more cloudy and other times more sunny.  Highs range a bit hotter from the upper 80s to the low 90s along with moderate-to-high humidity.  Showers and thunderstorms should pop up again this afternoon and evening (40% chance). If you get rain, it’ll probably range from a trace to a quarter inch, but some areas could see locally heavy amounts with downpours. Winds from the southwest at 5-10 mph.  Confidence: Medium

Tonight: Scattered evening storms still at about a 40% risk with otherwise partly cloudy and still muggy conditions as lows only dip down into the low to middle 70s (which is still 5-10 degrees cooler than most of last week’s minimums!).  Breezes are from the west and northwest at 5-10 mph. Confidence: Medium

Tomorrow (Wednesday): A cold front is sputtering its way through the area, so skies should range from partly cloudy to sometimes mostly cloudy as high temperatures only reach the middle to upper 80s across the area. Humidity starts to tick lower with dew points dropping into the middle to upper 60s.  There is still a 40% threat of showers and storms though with the front hanging around.  Breezes are from the west and northwest at about 5 to 10 mph. Confidence: Medium

Tomorrow night: Things really start to improve by this point with just a few clouds around and lowering temperatures as well as humidity.  In fact, the odds are improving for both the city and the suburbs to break below 70 degrees with lows in the low-to-middle 60s favored.  It might actually be pretty darn nice. Confidence: Medium

A LOOK AHEAD

Thursday looks like a much nicer day overall.  In fact, I’m issuing a Nice Day Watch as the potential exists for Nice Day conditions throughout the area.  Partly to mostly sunny skies, low humidity, and temperatures in the lower to maybe middle 80s may indeed qualify this day for the nicest day in a few weeks.  Stay tuned for updates on this developing situation.  Otherwise, Thursday night could see a few clouds as temperatures should again dip into the low to middle 60s with relatively low humidity again.  Confidence: Medium

Friday is favored to be partly to mostly sunny with highs in the middle to upper 80s along with low-to-moderate humidity levels.  This could be the second best day of the week.  Friday night should be partly cloudy with lows in the middle to upper 60s (around 70 again right in the city) as the humidity creeps back up a bit. Confidence: Medium

The weekend is looking somewhat trickier as a cold front approaches the area.  Saturday should see partly sunny skies with highs in the middle to upper 80s, but a 30% chance of afternoon and evening thunderstorms.  We’ll still be ahead of the front Saturday night so lows dip down only into the upper 60s to low 70s with moderate humidity.  Sunday is expected to see the cold front with more widespread showers and storms, especially by the afternoon.  Moderate to maybe high humidity should accompany highs in the middle to upper 80s.  Confidence: Medium-High
