Today's Daily Digit
A somewhat subjective rating of the
day's weather, on a scale of 0 to 10.


A second straight day with highs struggling to reach average -- gotta love it, even if a shower can't be ruled out.

Today: Partly sunny. Chance of a few mainly p.m. showers. Low-to-mid 80s. | Tonight: Partly cloudy. Upper 60s. | Tomorrow: Partly sunny. Decreasing humidity. Mid-to-upper 80s. | A Look Ahead | Get Express Forecast by E-mail


Are you excited for this forecast?... You should be. Maybe not as much for today, though most of the day should be perfectly fine. But definitely for tomorrow through Saturday, when each day features highs in the pleasant 80s, gloriously low humidity and plenty of sun. Temperatures and humidity may be on the rise again come Sunday, but neither should be too intense. So enjoy the homestretch of what's turned into a rather tame August compared to the record heat of June and July.

Radar & lightning: Latest D.C. area radar shows movement of precipitation and lightning strikes over past two hours. Refresh page to update. Click here or on image to enlarge. Or see radar bigger on our Weather Wall.

Today (Wednesday): We should see enough sun between clouds to boost highs to the low-to-mid 80s with still some humidity around. An approaching cold front, albeit weak and well to the west, combined with low pressure lingering in the upper atmosphere, could support development of a few showers or an isolated t'shower during the afternoon into early evening (25% chance you'll see raindrops where you happen to be). Confidence: Medium

Tonight: The shower threat should end by early-to-mid evening. Partly cloudy skies continue overnight as most spots see lows in and around the upper 60s. Confidence: Medium-High

Keep reading for the forecast through the weekend...

Tomorrow (Thursday): Refreshing breezes from the northwest (10-15 mph at times) bring decreasing humidity. Skies should be at least partly sunny with highs somewhere in the mid-to-upper 80s. Confidence: Medium-High

Tomorrow Night: We've waited a while for a night like this -- mostly clear with wonderfully low humidity for August and lows in the upper 50s (cooler suburbs) to low-to-mid 60s (downtown). Confidence: Medium-High


Mostly sunny skies and low humidity combine for nearly flawless weather Friday and Saturday. Highs head for the low 80s Friday and mid-80s Saturday, with Friday night and Saturday night lows cooling down to the mid-to-upper 50s in the suburbs and probably low 60s downtown. Confidence: Medium-High

Sunday may not be as perfect as Friday and Saturday. But it still looks like a pretty great day. Skies continue mostly sunny as temperatures heat up a bit to highs in the upper 80s to near 90. Humidity creeps upward, but only to the higher end of the low range. Confidence: Medium

First. Nice cool morning. Little or no rain here thus far. Dry period expected as little moisture with next cold front, then strong high pressure for now.

Love the weather, but also disappointed that we received no more than a drop of rain during the first half of what I expected to be a showery week.

I agree with the little rain sentiment. Are we still low for the summer on rainfall? I assume we are.

Are we getting a Nice Day icon for tomorrow and Friday??? This morning was lovely, a nice cool breeze. Too bad I have meetings scheduled for Friday, it appears to be a good day to play hooky!

Acuweather has backed off that truly horrendous heat forecast for end-of-August into the first week of September. There still could be some low 90s days, but if the Labor Day weekend forecast of upper 70s-low 80s holds up, will be so nice.

Friday looks pretty good for getting the Nice Day stamp. Tomorrow may be borderline for high temps, which are supposed be between 65 and 85 to get the Nice Day nod (see criteria here). But maybe we'll be lenient ... you'll just have to find out in the morning :)

NWS says we're still about four inches short of normal for the year. (21.36" since Jan 1, average is 25.46".)

Yes... the rain reality of upper-level systems can sometimes fall short of expectations.


The immediate D.C. metro area is actually ok for precip, running around average over the last 90 days as seen on this map. However, as you can see on the same map, if you head south/southwest from the metro area, or north/northwest, you pretty quickly run into substantially below-normal precip conditions. This is reflected in the Drought Monitor with much of northern and eastern Virginia, and parts of western Maryland and the West Virginia panhandle, categorized as moderate to severe drought. And while the metro area is ok for now, it's never great to be downstream of an area experiencing drought.

Sure wish the "much-needed-rain" crowd would quit whining all the time. I'm enjoying the dry, cool weather for now. Seems as though the heat is getting ready to make a run at us next week.

In the mountains east of Front Royal, we got about 1/4 inch of rain yesterday and the high was 66, low was 59 last night, and it's a nice day after a cloudy morning... currently 72

Can't wait to start using the gazebo outside on these nice cool nights!
