Today's Daily Digit
A somewhat subjective rating of the day's weather, on a scale of 0 to 10.
7Hot to be sure. But it's summertime. We can't be that surprised.
Get tomorrow's 'Digit' on Twitter tonight


Today: Sunny and hot. 92-96. | Tonight: Mostly clear. 67-72. | Tomorrow: Sunny, more heat. Low 90s. | A Look Ahead | Get Express Forecast by E-mail


"Official" summer begins tomorrow, but we've already had over a week's worth of 90+ days this June, not to mention a handful in April/May. We'll definitely add to those totals as we could see nearly a week straight of daytime highs at or above the 90 mark. Early in the forecast period, a weak front knocks down the humidity a peg or two. But by midweek, the stickiness returns, and so do afternoon thunderstorm chances.

Today (Sunday): After a weak front washes out over the area this morning some clouds may linger through your morning coffee, along with the tiniest chance (<20%) of a shower. The front drops dew points a few degrees lower, but the difference in humidity is hardly noticeable. Heat remains as we reach the low-to-mid 90s under sunny skies. Winds light and out of the west at less than 10 mph. Confidence: High

Tonight: We'll be considerably less oppressive in the mugginess department, but still summer-like. Skies will be mostly clear, and temperatures drop to the low 70s to near 70 in the District, upper 60s outside the Beltway. With nearly calm winds, don't be surprised if some of our rural areas report fog by morning. Confidence: High

Keep reading to see if we'll cool down anytime soon....

Tomorrow (Monday): A new week begins with our 3rd day of highs in the 90s. High pressure is in control keeping our skies clear aside from some afternoon fair-weather cumulus. Winds out of the south slowly start to add to the humidity levels, but we won't be too uncomfortable with highs in the low 90s. Confidence: High

Tomorrow Night: Humidity levels build tomorrow night and it'll be another night we'll be thankful for central air. Skies will be partly cloudy, and overnight lows only drop to the low-to-mid 70s. Confidence: Medium-High


By Tuesday, I'm sure we'll be hearing "heat wave" thrown around. Highs themselves will likely be held in check, around 90, by increased afternoon cloudiness. But dew points will rise to the upper 60s, and I, for one, would rather they not. Nonetheless, expect a typical "dog-days of summer" type day, with the small chance of some late afternoon/evening T-storms (20%).

Overnight, any storms subside, and we'll have mostly cloudy skies and lows in the mid-70s. Confidence: Medium

Wednesday holds our best chances for rain this week. Don't expect it to bring much relief though as we'll still have quite a warm day. Partly sunny skies allow highs to likely crack 90, but scattered thunderstorms probably threaten by the afternoon (40% chance). Confidence: Medium

Will this be the hottest June on record? Sure seems like it.

Folks - I know this is a few days out, but I have tickets for Wednesday's Nats game at 4:30. I REALLY want this game to go on (my first visit to the park this year). It shouldn't be a washout right, just a potential boomer and delay or something?

Any storms Wednesday look to be scattered, hit and miss,and short-lived. Wouldn't worry about it.

Thanks, Jason. If I catch a foul ball I'll mail it to ya!

For me school ends on Thursday and i want it to be nice out what are the chances of rain on thursday and friday?

Snowlover, with a nearby disturbance, and no dominant high pressure area, I'm keeping shower chances in the forecast through Friday, most likely in the form of afternoon thunderstorms.

Rain threats 4 days out of 6, though most of the time it's only 20-30%...possibly rain on at least one day from Tuesday onward. Still not really a "dry" summer, though.

There does seem to be a bit of convection in the cumulus this my afternoon trail hike could be impeded by Code Orange air quality.

There's also just the hint that some sort of tropical disturbance could form near the Yucatan Peninsula aoa Saturday. My dance nights this week are Tuesday, and perhaps tomorrow and Friday. Good dances Friday night at the Elks Lodge & last night at the Falls Church Unity Club on Broad interference from "much-needed-rain" for a change!

I'm not sure it matters if there is a risk of rain every day if it never rains...

Are we really going to be in the 90s+ for the next two weeks or so? I've been here over a decade and I can't remember the last time we had this much heat for such a sustained period.

As usual Ian you have the most entertaining way of expressing the weather. "I'm not sure it matters if there is a risk of rain every day if it never rains... " hmm... If a tree falls in the forest...

Centreville VA 91 degrees this afternoon. 105 on mercury thermometer out on deck that gets full afternoon sun.
No relief except for momentary sun cover ups by random clouds. Brutal!

Wow, just felt that the humidity was not as bad today as yesterday, and certainly not like last weekend. We had a wind starting this a.m. from the northwest, but never the oppressiveness I was expecting. In fact, it was quite nice out there once the sun set ... longest day of the year ....?

I see high in the 90s for the next 7 days and no solid chance for rain. Are you KIDDING me? This is only June!

This is problem with living in the mid Atlantic states. The south will have crazy hot days worse than that but at least won't get the 20 inch + blizzards!
