At least for the next 3 days, this is not the summer we have come to know. Unusually low humidity promotes afternoon splendor and allows overnight lows to fall well below normal. However, as we approach the end of the month and the end of the climatological summer, the threat of more 90+ days returns Sunday. It is interesting to note that while this summer has averaged more than 4 degrees above normal, it has also ended up ever so slightly wetter than average. That's quite a feat since we were surrounded by unseasonable dryness throughout much of the Northeast and mid-Atlantic.

Today (Thursday): Sunshine radiates in abundance for the morning with readings in the 70s with moderate humidity levels. Gentle breezes blow from the northwest. The sun is still high enough in the sky to push afternoon maxes to the mid-80s but you'll notice the air is becoming drier. There could still be some afternoon pop-up clouds but rains chances are minimal. Confidence: High

Tonight: Clear, calm and low humidity equal a delightful evening. Evening readings still hold in the upper 70s to lower 80s. A steady drop overnight results in mid-to-upper 50s in the burbs and lower 60s downtown. Confidence: High

Keep reading for the forecast through Monday....

Tomorrow (Friday): This is a Nice Day icon winner with breathtaking low humidity! We'll have abundant sunshine with highs only in the upper 70s to lower 80s. Even the breezes are light out of the north. Confidence: High

Tomorrow Night: A great night to be out and about and enjoy 70s in the humidity-free environment. Temperatures drop quickly overnight and 50s cover all areas except for downtown where low 60s still win out. Confidence: High


Saturday morning is mighty fine with bright sunshine, 70s and calm winds. By afternoon, summer reasserts itself pushing readings well up into the 80s in most areas. It's a close call but we should escape 90 downtown. The evening is warm but pleasant as humidity still fails to compare to earlier days. Confidence: High

Sunday reminds us that summer is not quite over. Morning lows in the upper 50s to lower 60s quickly give way to strong warming and just a hint of humidity. Skies remain perfectly clear allowing highs for the day to top out in the upper 80s to lower 90s. Evening is still warm with 80s slowly fading away. Confidence: High

Monday starts out in the 60s but ends up just a little warmer and a little more humid than the day before. Pervasive sunshine and light breezes are nice but highs in the upper 80s to lower 90s keep the air conditioners humming. Confidence: High

Sounds like an awesome weekend in Ocean City. And swellinfo is calling for chest high surf!

Great weather this morning, 69 degrees. However buildup of high pressure ridge for next few days may lead to persistent "much-needed-rain" whining due to expected dry conditions. Great weather for this weekend's dances, including near-optimum temperatures at Glen Echo Spanish Ballroom.

CWG & fellow posters - I hate to do this but I need a favor.
We'll be tent camping on the North Rim of the Grand Canyon the first week of Sept.
I can't seem to find a weather forecast for that specific location anywhere on the web.
Every site I try defaults to the south rim , Phantom ranch down at the bottom of the canyon, the "airport" (also south rim)or one of the towns nearby like Fredonia. The north rim has an elevation of over 8000ft and has a completely different climate from any of these places.
Oh, and it's very nice out there this morning. I'd like to take this weather in my pocket for the vacation.

Kanab Utah is close enough:

If you get the chance, the Toroweap Overlook of the North Rim is very impressive. 2 Hours south of Colorado City/Hildale on a dirt road.

Basically, you walk up to the edge and look 3000 feet straight down. The "regular" North Rim gives you a sense of the /width/ of the Canyon, but Toroweap gives you the /depth.

wiredog - Thanks I think Kanab is a lot lower elavation hence the predicted highs in the 90's. I don't believe we'll see any 90's on the north rim.
We camped at Toroweap on our honeymoon in 2001 and will be going back for a day trip on this vacation. It's not a place for children, pets, fools or those with vertigo. A good sturdy high clearance vehicle is a necessity because that road can be nasty.

According to the Drought Monitor, practically the whole state of Virginia except the DC suburbs and the far, far west is in a state of drought. So, this will only exacerbate the problems our farmers and rural neighbors are facing...

FIREDRAGON47 - Yeah, you gotta correct for altitude, which drops the temp a few (10 maybe?) degrees.

I lived in Cedar City UT for 10 years and got all over around there.

Firedragon, you can get forecasts for that side of the canyon by using the NWS site. I just clicked on the map and it gave me a forecast for 8000ft elevation. just go to and click on Grand Canyon and then click on the close up map for your point of interest.

Thanks David that looks about right. Day temps 70's night temps 40s with a chance of t-storms every day.
I'm just hoping we don't get caught in monster summer hailstorms on like we have the last 2 years during trips to the Colorado San Juan mountains & Yellowstone.
