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


Warm 80s, low humidity, more sun than clouds=pretty great, notwithstanding some pollen.

Today: Mostly sunny, few p.m. clouds. Low-to-mid 80s. | Tonight: Clouds slowly increase. Stray shower possible. 60-66. | Tomorrow: Mix of clouds & sun. Around 80. | A Look Ahead | Get Express Forecast by E-mail


Our short-term streak of decent, fairly autumnal weather is hard pressed to end. Even a weak cold front that would like to move through our region tonight should only throw a few clouds our way (and perhaps an isolated shower). While this cool, dry air reinforcement should keep our temperatures and humidity in check for a bit, we do need the rain. Summer not to be forgotten, we may get warmer reaching up to around 90 degrees by midweek..

Today (Sunday): A pretty darn nice day with sunshine in the morning, and just a few clouds increasing during the afternoon hours. High temperatures feel great in the low-to-mid 80s because of the dew points in the 50s (making it feel essentially humidity-free). Enjoy the Dupont Farmer's Market or your kickball game! Winds will be light ahead of a weak, moisture-starved cold front, from the southerly direction. Confidence: Medium-High

Tonight: Clouds gradually build up overnight and temperatures only slowly drop into the low-to-mid 60s in most areas. A stray shower can't be ruled out, mainly early. Confidence: Medium

Keep reading for the forecast through midweek...

Tomorrow (Monday): Despite scattered clouds in the morning, another fine day is in the cards. Temperatures warm back up with the afternoon sunshine, to around 80 in most spots. Light winds come from the north and west lowering our dew points. This ushers in that crisper, dryer autumnal air we've started getting a taste of recently. Confidence: Medium-High

Tomorrow Night: Skies are mostly clear and we relish in the dry and comfortable air. Lows are expected to cool off in the range from the upper 40s to mid-to-upper 50s (downtown). Open those windows! Confidence: High


Tuesday is a still slated to be a comfortable day without much humidity but sunshine encourages temperatures to reach into the low 80s or even a bit warmer. Look for clear skies for most of Tuesday night as the lows drop down slightly less, into a broad range from the lower 50s in the cooler suburbs to lower 60s in the city. Confidence: Medium-High

Wednesday finds our area perhaps entering another warm spell? OK, maybe I should say hot. Temperatures threaten to top out around 90 degrees. Humidity may creep up slightly as well. Lots of sunshine contribute to our midweek weather heat, and we slowly edge toward D.C.'s record number of 90+ degree days in one season. Could this be day #64? Confidence: Medium

Camden? Thanks to a generous supply of fexofenadine, singulair, peusophederine, etc., hanging in there 'til stuff starts freezing.

And wondering if how many calendar years have seen 40" of snow in Washington? We're not there yet for 2010, at least at DCA.

Hi Jerry - yup same meds here for allergies haha. Can't wait for that first frost too! If Ian signs on, his statistics expertise ...he could probably answer your 40" snow question. I'm not able to research this for you at the moment, sorry

Please send some rain, next 7-8 days still look warm & dry, at least we can all go dancing, except the farmers who r all crying 4 rain.
So Steelers & Hokies.

@vatechbob, I talked to one of the vendors at the Dupont Farmer's Market and "brutal" is the way he describes this year's drought. He said they only had .2" last week at the farm in southern Pennslyvania last week.

But everything is ripening early; plenty of apples and pears this a.m.

@Camden, the 40" snow DCA/Wash, DC in a calendar year question was probably best asked during the week. I'm thinking it could have happened in 1996, or maybe 2003, but I don't save my old World Alamancs and I can't find online.

Heard the apples r small but sweeter, not usual during extremely dry growing seasons. The people who oen winerys r happy over the cond., since dry hot weather is good 4 grapes & dancing.
Hokies & Steelers win, Skins lose, great sports weekend.

jerry, will try to research in front of computer for your this week.
vatechbob, you're ready for some apples, eh? :) I can't wait to taste some near dc soon!

Remind me what a hot spell feels like??

Will it be similar to last Saturday? (It was pretty warm when I went to H Street Festival!) Just a bit warm (a linen scarf will do), a bit of breezes which is terrific for sunbathing...

Or it will be similar to your typical hot&humid July day that everybody (or at least those who are sane) fears? The one that makes you yearning for an ice-cold shower?

I am terrified of those July summer days.

Camden, thanks re: researching the calendar year L St./DCA snow totals of 40-plus inches.

Several periods look especially promising:

1890-94 (135.2" for the four winters)(whoa!)

1904-06 (66.7")

1908-09-1911-12 (117.6")

Plus there are several times from the mid-1950s onward when it might have happened.
