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


We'll take any a.m. rain we can get, and can then enjoy a mostly dry afternoon.

Today: A.M. showers, then mostly cloudy. Near 80. | Tonight: Mostly clear. 62-70. | Tomorrow: Mostly sunny and hot, but less humid. 89-93. | A Look Ahead | Get Express Forecast by E-mail


The rain we get today - while helpful for parched lawns - is unlikely to put a serious dent in the drought. Then we slowly dry out, but characteristic summertime heat sticks around. At least we'll get a semi-reprieve from the humidity on Sunday and Monday. The mugginess starts to build back into the region towards the middle of next week when we'll get the next chance for showers and storms.

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 (Saturday): (updated at 3 p.m.) Showers and a few embedded thundershowers move through this morning -- especially early in the morning. Locally heavy rain is possible with amounts around 0.5" possible. Skies likely brighten as we head into the afternoon but limited sunshine only boosts highs to near 80. A late afternoon shower or thundershower can't be ruled out but mainly east of the beltway and more towards the Bay.Confidence: Medium

Tonight: Skies should gradually mostly clear out. It will be a fairly typical summer evening with lows around 70 in the District with 60s in the suburbs. Confidence: Medium-High

Keep reading for the forecast into early next week...

Tomorrow (Sunday): This is the pick of the weekend for outdoor plans (although Saturday afternoon should be fine). The sun shines all day propelling temperatures into the low 90s. On the plus side, humidity levels will be tolerable with dew points dropping into the high 50s in the afternoon. We'll have a light wind from the northwest at 5-10 mph. Confidence: High

Tomorrow Night: It's a mostly clear and balmy evening with lows from the mid-60s in the cooler suburbs to the low 70s downtown. Confidence: High


Monday will be a lot like Sunday: hot but with tolerable humidity. Highs head back up into the lower 90s. The humidity increases Monday night making for a muggy night with overnight lows in the upper 60s (in the suburbs) to mid-70s (in the city). Confidence: Medium-High

Winds from the south make for a sticky Tuesday. Highs head up to around 90 but it will feel a little hotter than that. The increased moisture in the air coupled with a weak disturbance heading towards the region could trigger some late afternoon or evening thunderstorms (30% chance). Confidence: Medium

Centreville VA Trace of rain last night.
Hoping for something a little more substantive today. Radar looks promising.
At least it's not 100 degrees.

Light, steady rain in Merrifield this morning; my area will get a little soaking, at least. It doesn't sound as if tomorrow's wind will be enough to move my boat around, but I may go out on the Potomac for a while in the morning anyway - just to say I did it.

Rain looks pretty widespread to me on the radar, with heavier stuff yet to move through here in Dunn Loring. Forecast seems a little conservative on the rain front.

Posted by: Axel2 | July 10, 2010 7:21 AM | Report abuse

Looks like a relatively brief period of moderate-heavy rain then outta' here by mid-morning. No mushrooms from this system.

Pouring in Burke at 7:43.

Looks like the 1/4 to 1/2 band is working through east of the mountains, but I think there will be more bands later the further east you are. Here to the west there is a bit of clearing. This would be the drizzle part of the event, but it's July so no drizzle. Got 1.5 inches and most of it seems to have soaked in.

Yes! Rain! We need it so much. It's been a long time since the area has awoken to a rainy day. Hope this helps the dry lawns a bit.

Very happy that the band of rain that fell apart last night, giving us nothing, reformed this morning. Been raining- light to moderate- since around 6 this morning in the Laytonsville area.

Original forecast (which has been updated) was a little conservative on rain. Band of rain really came together this morning--a good thing.

Posted by: Jason-CapitalWeatherGang | July 10, 2010 9:14 AM | Report abuse

We need much more precip than what we're getting this a.m. Best hope now is a tropical weather system will form south of here, work its way through the region, and give us a copious downpour. This a.m.'s rain is OK but it's a hardly more than a thimbleful compared to the buckets we need.

Arcola,VA - moderate steady rain for about 2 horus in early morning. Got at least 0.5 in from the gauge.

Posted by: LoudounGeek | July 10, 2010 9:39 AM | Report abuse

Looks like we got another inch overnight... 2" in the bucket this morning.

Cloudy and 65.8F east of Front Royal @ 1900 ft

Steady rain throughout my 16 mile run from Dangerfield Island out and back on W&OD trail. Moderate pace of rain, no downpour but no real letup either. Exactly what we needed. Still raining a bit in north Old Town.

Everyone seems happy for cool and rainy weather, right? I see some nice, much-needed, rain totals too!

Posted by: Camden-CapitalWeatherGang | July 10, 2010 11:27 AM | Report abuse

Still raining in Old Town - loving it even if the dog is furious.

The Weather guy on News Channel 8 just said this is the rainiest day this calendar year.

Posted by: rwalker66 | July 10, 2010 12:07 PM | Report abuse

Rainest day this summer so far. Calendar year? the weekend of May 22-23 we had totally of 3+ inches of rain in the western suburbs.

Cam - no complaints. But looks like this rain band is packing lot more moisture as it passes thru Philly & New Jersey. Some areas up there will get 2-3 in.

Blue sky & some sunshine breaking out in Centreville VA.
I don't have to water today.....yay!

Cloudy weather has been a bit gloomy and depressive, but the rain has been more of a soaking rain than the heavy disruptive thunderstorms we usually get this time of year. According to the Weather Channel, we have a rain threat much of next week. Not really a drought by my reckoning!

BTW, since when has half an inch been "locally heavy"? Unless it comes all in the space of five minutes, it's a moderate rain by my standards. I tend to define "heavy" rain as a rate of at least an inch per hour--this seems to be principally a moderate rainfall.

At 4:45pm my rain gauge (from Casey Trees) only registered a bit over half an inch of rain. It had been a slow, gentle rain--and unfortunately for trees, etc. there wasn't more of it.

I'm hoping the drought has been "broken". Obviously we need a lot more rain to make up for a dry June. Hopefully the moisture that lingers from this morning and a slightly different pattern will contribute to daily thunderstorm chances with higher coverage.

@Smparry, Adam Caskey mentioned on Channel 7's 6:00 p.m. newscast that he got .52 in his Arlington backyard, which is very similar to your total.

But, at this point any soaking rain is welcome and so are the cooler temperatures. Next week's forecast of afternoon thunderstorms is encouraging (so long as the storms don't go ballistic).

Peach season is or soon will be
here. Luscious, sweet Allman Brothers-type peaches, where the juice drips down your chin are much tastier than scrawny peaches from orchards that didn't get enough rain (or weren't sufficiently irrigated). The later-ripening peaches will benefit from any and all rain we get in the next few weeks, so bring it on!

What a beautiful day, not gloomy at all! Wonderful rain (albeit NOT nearly enough to "break" the moderate drought), and I appreciate every precious raindrop that falls. Even with the 1"+ at National Airport today, DCA remains fully 5" BELOW normal for the year.

Agree with JerryFloyd1; unless the pattern changes to deliver significant rains at summer's end, the only way we'll get out of this drought will be a tropical storm. Let's hope we get one!

LoudounGeek, PHL received 0.55" today. PHL & NJ are "Abnormally Dry", which is not as serious as the drought conditions we face.

More rain, please!!

Posted by: TominMichiganParkDC | July 10, 2010 8:28 PM | Report abuse

We had an inch plus one-tenth. This included rain from Friday mid afternoon. Much needed. Agree with Loudoungeek, we had much more rain that May weekend .... And also agree, even an inch barely gives us a reprieve in the drought dept. Altho it's now a lovely night out there, not that much humidity ...
