Forecast: Heat wave is finally history
Beautiful stretch of 80s arrives; 90s back for the 4th?
FORECAST IN DETAIL
Finally!... 90s are out of the forecast, at least until the weekend. The humidity and thunderstorm chances also take a leave of absence for the next several days. Our heat wave is officially done after an 11th straight day yesterday with highs at or above 90 -- the sixth time on record that Washington's high has reached 90+ on 10 or more consecutive days before July, according to the National Weather Service. We do start to heat up again as we get into this weekend. Can we make it a storm-free 4th of July?
Today (Wednesday): That strange but welcome feeling as you head out the door this morning? That would be temperatures in the 60s to near 70 with wonderfully low humidity. We're looking at pleasant mid-to-upper 70s by around lunchtime, and afternoon highs in the low-to-mid 80s. All under partly to mostly sunny skies, with generally light breezes from the northwest. Confidence: High
Tonight: Just fabulous... With mostly clear skies, evening temps drop through the 70s, into the 60s late. The dry air pushes overnight lows down to the low 60s to near 60 downtown, and mid-to-upper 50s in the suburbs. Confidence: High
Keep reading for the forecast through the July 4th weekend....
Tomorrow (Thursday): The weather remains mostly unchanged tomorrow -- day 2 of our cooler-and-refreshing wave. If anything it may be a few degrees cooler than today with mostly sunny skies and highs near 80. Confidence: High
Tomorrow Night: Mostly clear and cool again, with lows in the 50s across the suburbs and low 60s to near 60 downtown. Confidence: High
More of the same Friday: Mostly sunny with low humidity and highs near 80. That's followed by a mostly clear and mostly fantastic Friday evening as temperatures fall toward 70, then to overnight lows in the 50s (suburbs) to low 60s (downtown). Confidence: Medium-High
Skies continue mostly sunny Saturday as a strong area of high pressure overhead keeps the humidity down. We'll be warmer though, with highs likely to reach at least the mid-80s and Saturday night lows in the 60s. Confidence: Medium-High
The July 4th high at Reagan National hasn't reached or eclipsed 90 since 2006, when the mercury topped out at 94. In the three years since, highs were 84, 88 and 87, respectively. With mostly sunny skies Sunday and a warming air mass, we may well break the 80s streak this year as highs probably make the low 90s. Fortunately, humidity shouldn't be too bad, though probably back up to noticeable levels. Right now I don't see any threat of showers or storms. Temps should be down to the low 80s or so come fireworks time. Confidence: Medium
Monday finishes out the holiday weekend hot -- highs in the 90s -- and it should be more humid, too. Unless something changes, it looks like we'll be well on our way to a week straight with no rain. Confidence: Medium
