Today's Daily Digit
A somewhat subjective rating of the day's weather, on a scale of 0 to 10.
9Patience is finally rewarded. Buh-bye heat wave, hello comfortable warmth.
Get tomorrow's 'Digit' on Twitter tonight


Today: Partly to mostly sunny. Very pleasant. Low-to-mid 80s. | Tonight: Mostly clear. Mid-50s to low 60s. | Tomorrow: Mostly sunny. Near 80. | A Look Ahead | Get Express Forecast by E-mail


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

It's amazing how temps are relative. High 60s in the dead of winter would be warm. This morning, after the heat wave, it feels cool.

At what point do we say we're in a drought? The drought monitor says we're abnormally dry.

O frabjous day! I was cold walking to work this morning. More of this, please.

Dan, what more could we wish for to make this day a 10?

Posted by: paperball | June 30, 2010 9:23 AM | Report abuse

I agree today is a 10. Temp was 55 degrees this morning in the mountains east of Front Royal.

Humidity 35%, dew point 40 degrees. You can't beat that. Enjoy it before the sauna returns next week.

I knew there would be calls for a 10 today! And Matt, I didn't miss your urging for a 10 yesterday. But I decided that with the potential for some clouds today I'd punt the 10 to David for tomorrow. I know, my standards are too high :)... Question for everyone out there. Would you enjoy a chance to vote your call on the digit on a daily basis?

This is the most gorgeous day in a long time! Thank you Weather Gods! I can't wait to go for a long, not-that-sweaty run after work today.

My mood is so much better in this weather! And Matt/Dan I love the banter about the daily digit. I say there is too much UV for a "10" because I could sunburn! haha, but perhaps voting is a cool way to further interact with all our vociferous readers out there ;) oh and 55F near Front Royal? sounds divine!!

Thank you, blablabla, for posting the current drought monitor.

As far as I'm concerned, we are in a (mild) drought. With the exception of February (which was less than 0.1" above-normal), 2010 has been VERY dry at National Airport, with only 13.6" of precipitation through the end of June. (By comparison, Boston has had over 29" this year!).

Combined with significantly above-average temperatures, the proof is in our scorched lawns and wilted trees.

Bring on the RAIN!

Always like to see the word 'fabulous' in the forecast. Fabulous is right! Today's a 10 in my book ;)

Yes, it's cool and a nice break from the oppressive humidity...but the overcast skies here in Alexandria make it less than perfect pool weather. We've had zero sun all day. A clear blue Sept sky and these temps would make today a "10" in my book.

Let's quit whining about "drought" have to consider December as well as February when talking snow this past winter!
