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


Fewer clouds than Friday so this should be a legit 10. Give us a mulligan :)

Today: A few clouds, pleasant. Near 80. | Tonight: Increasing clouds, rain likely late at night. 60-65. | Tomorrow: Occasional showers, especially before noon. Near 75. | A Look Ahead | Get Express Forecast by E-mail


We got a lot of complaints that yesterday's "perfect 10" didn't live up to its billing. Hopefully, today's beautiful conditions make up for it. Sunday won't be so pretty with overcast skies and some showers. But we all know we need the rain and our gardens will be thankful. The beginning of next week promises to be stellar. This is a terrific time of year for weather in our area...

Today (Saturday): We should have considerably more sunshine than yesterday as the atmosphere stabilizes a bit. Still, don't be surprised to see some clouds at times, especially in the afternoon ahead of an approaching frontal system. Temperatures are pleasant, starting the day in the 50s before reaching the 70s and ultimately close to 80 in the afternoon. We won't have much of a breeze, blowing at about 5-10 mph from variable directions. Confidence: High

Tonight: Clouds steadily increase but umbrellas won't be necessary unless you're staying out past 2 or 3 a.m. Towards the predawn hours, some showers are likely (60%), with lows from 60-65 (suburbs-city). Confidence: Medium-High

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

Tomorrow (Sunday): Showers are likely in the morning (60-70% chance) but should decrease in coverage during the afternoon - when showers odds drop to 30-40% and are probably more intermittent. Nonetheless, the frontal system crossing the region is a slow-mover, so don't expect rapid clearing - with mostly cloudy skies all-day more than likely. It's a little humid, with highs in the mid-70s. Overall rain potential is about 0.25-0.5". Confidence: Medium-High

Tomorrow Night: The shower threat comes to an end by or during the early evening (see the season debut of SkinsCast if you're headed to the Redskins-Cowboys game). Skies slowly clear into the overnight, with some patchy fog possible by morning. Lows range from the upper 50s in the cooler suburbs to the low 60s downtown. Confidence: Medium-High


The start of the week looks outstanding -- with mostly sunny skies both Monday and Tuesday, and highs in the low 80s. Overnight lows are comfortable, ranging from the low-to-mid 50s in the cooler suburbs to the low 60s downtown. Confidence: Medium-High

Felt great when I went out to get the paper. Off for a run and a stop by the farmer's market.

I agree with your "10". Great day for a Navy football game. Just wondering how much below we are precipitation-wise? I'm seeing about 2.5" out in Western Loudoun? The "grass" looks like hay!

You all must have been beer-goggling if yesterday was a 10, but today looks legit - what was up with all those cumulus clouds? Perhaps you could do a segment on fair-weather cumulus clouds detracting from an otherwise perfect day? Here's the pattern I've been noticing - sunny in the morning; increasing clouds at midday; back to clear by sunset. Why does that happen? It reminds me of where I went to school in northern England - in the summer, if you weren't up by 9 am, you'd miss the sun completely; but by nightfall, it would clear up again.

The clouds yesterday were due to the strong sunshine interacting with cold air aloft. It created an unstable situation, so we had clouds. We had a few clouds in the forecast, but they were more prevalent than we thought.

No doubt today is much better. About to head to a picnic...

Jason, a whole bunch of folks will be doing the Nation's Triathlon tomorrow morning. Athletes will be getting down there around 6 am, with the first swimmers in the water at 7 am and the whole thing done by 2 pm. Could you expand on the forecast through those hours? Looks like it'll likely be drizzly but not terribly cold. What are the chances of thunderstorms? Thanks.

Re: England summer daytime clouds. More moisture, same strong summer sunshine, but colder air aloft (further north than us). It is especially noticeable in spring and early summer when the sun is stronger but the air aloft is still cold. The fall tends to dry out with a weaker sun. Yesterday it was in only the mid 50's in Hot Springs, VA (elevation 3793) when we had our clouds.

A few clouds make a perfect day for me. Especially cumulus! Hasn't anyone ever lain down on a hill looking up at clouds?

This is probably a bit too late as I'm sure the CWG is out enjoying this beautiful day. Even if there is a bit of haze. My condo association is having its annual outdoor grill tomorrow at 5 p.m. I'm scheduled to handle meat. Burgers, sliders, hot dogs, and some brats. Anyone care to give odds on the weather clearing by 5?

Looks pretty showery through much of the event (chances of thunder/lightning are low), maybe starting to improve toward or after noon. Temperatures slowly rising toward and into the 70s

I'm wondering if, when you do the 90+ seasonal roundup, you could also do an air quality summary for this summer? Seemed to be fewer code red days, but plenty of orange ones, and wondering how it compares with other summers. Hoping your software makes this easier for you than for me!

Once we get to the 5-8 p.m. range, if there are still any showers around (20-30% chance), they would likely be light and intermittent, or just a bit of drizzle.

Thanks for the explanation guys!
