The fascinating part of this meteorological summer so far is the short-lived nature of our warm-ups.  We get just a few days of warmer temperatures, sometimes even miss the 90s, and get mired in some uncomfortable humidity.  But we can always point to another cool front on the horizon with better days ahead.  Today’s the most humid day of this week with relief filtering in late tomorrow and especially Thursday and Friday.  The weekend should start nice too, but we may inch up that humidity again by Sunday with some late day thunderstorms too.

Today (Tuesday):  Partly to mostly cloudy skies dominate today with scattered shower and storms most favored to be across the southern half of our region (60% likelihood).  Highs range in the low-to-mid 80s, which isn’t bad for mid-June, but the dew points are in the mid-to-upper 60s which is inside the discomfort zone. Rainfall totals will vary wildly from nothing/trace up to a half inch or more with heavier storms.  Winds are from the southwest at about 10-15 mph. Confidence: Medium

Tonight: Scattered showers and storms are most numerous in the evening, but we can’t rule out an overnight rumble or passing shower as the cool front approaches the region.  There is a 40 percent risk of something passing over your locale.  Lows drop into the low-to-mid 60s, but partly to mostly cloudy skies offer the chance of warmer results.  Confidence: Medium

Tomorrow (Wednesday): A lingering 30 percent chance of mainly light showers especially in the morning as the cool front makes its move on our area.  Highs should range through the lower 80s with some partly sunny skies and lowering dew points in the afternoon (dropping into the more pleasant upper 50s).  Light winds from the north and northeast.   Confidence: Medium

Tomorrow night: Either way, tomorrow night should still see partial clearing with lows dropping into the more comfortable middle 50s in the outer suburbs to low 60s in the city. Confidence: Medium-High

A LOOK AHEAD

Thursday is fantastic and sunny with a great chance to qualify as a Nice Day status as highs only reach the low-to-mid 80s and dew points stay down in the drier, more comfortable mid-to-upper 50s.  Ah. That night features lows dropping into the comfortable upper 50s to low 60s around the area.  We may need to introduce a Nice Night symbol for such comfortable summer weather. Confidence: Medium-High

Friday edges just a touch warmer with partly to mostly sunny skies and highs in the middle 80s.  That dew point may sneak closer to 60F too, but that is still fairly comfortable for D.C. summertime.  Friday night is partly cloudy to clear with lows in the low-to-mid 60s. Confidence: Medium-High

The weekend starts out superb with middle to maybe upper 80s on Saturday under mostly sunny skies and reasonable humidity levels.  Saturday night should be partly cloudy with lows in the 60s.  Sunday begins our next round of a bit more heat and humidity.  Highs reach up around 90 with moderate humidity returning along with about a 30 percent risk of afternoon to evening thunderstorms.  And the cycle starts again.  Confidence: Medium
