Splendid Friday to soak up the sun. If only the high heat wasn't preparing to pounce.

Today: Sunny, low humidity. Low 80s. | Tonight: Mostly clear. Mid-50s to low 60s. | Tomorrow: Mostly sunny & warmer. Upper 80s. | Sunday Mostly sunny, hot & somewhat humid. Mid-90s. | A Look Ahead | Get Express Forecast by E-mail


A. Camden WalkerAnticipation of serious heat returning by July 4th is all the more motivation to cash in on today's final wonderful day in this mini "spring wave," if you will. Highs skyrocket well into the 90s Sunday. And it appears the heat will set up shop for another extended stay, with temperatures possibly flirting with 100 at times next week. So get ready to roast -- and with little to no chance of cooling rain in the foreseeable future (that's probably bad news for folks in the Maryland 'burbs now contending with water restrictions).

Today (Friday): Enjoy this last near-perfect day before we ramp up into the next heat wave. It's another somewhat crisp morning as temperatures rise into and through the 60s. Highs should only reach the low 80s under brilliant sunshine. And our recent reprieve from humidity remains intact as well, with light and refreshing breezes out of the north. Slap on the sunscreen, then get out and enjoy! Confidence: High

Tonight: Skies should remain mostly clear, with evening temperatures falling through the 70s, and into the 60s by late evening. Overnight lows drop to the mid-to-upper 50s in the suburbs to the low 60s downtown, as heat quickly escapes back into the atmosphere without clouds insulating us. Even downtown, it may be one last night to sleep with the windows open. Confidence: High

Keep reading for the furnace -- I mean, forecast -- into next week...

Tomorrow (Saturday): The heat begins its return. Mostly sunny skies help highs shoot back up to the upper 80s, which is right around the average this time of year. Maybe some spots touch 90. Good news is humidity, while slightly higher, is still pretty much a non-factor. Also a non-factor?... the threat of showers or storms, which is slim to none. Confidence: High

Tomorrow Night: Now the humidity starts to rise some more and we're no longer talking 50s in the suburbs, even with mostly clear skies. Most everyone should see lows in the 60s (low-to-mid 60s outside the Beltway, mid-to-upper 60s downtown). I think I'll leave my air conditioning on, and windows closed! Confidence: Medium-High

Independence Day (Sunday): Time for the heat to really crank up. Mostly sunny skies beat down on us once again, as highs climb to the mid-90s. While it's good news for outdoor activities and fireworks displays, the little to no chance of rain means no break from the searing heat. If it's any consolation, humidity shouldn't be too bad -- noticeable, but only approaching or reaching the moderate range. Confidence: Medium-High

Partly to mostly clear Sunday night with a continued summer theme. Mugginess increases during the evening and into the overnight, with temperatures at fireworks time mainly in the 80s. Lows in the upper 60s (coolest suburbs) to mid-70s (downtown). Confidence: Medium


Monday, Tuesday & Wednesday reach the witheringly hot category. Poor air quality is likely along with hazy and humid conditions. Temperatures soar, under partly to mostly sunny skies, to highs in the mid-90s to near 100. We can hold out for a 10% chance of a shower or thunderstorm each day, but more than likely raindrops are not in the cards. Confidence: Medium


The holiday weekend beach forecast is for mostly sunny skies up and down the mid-Atlantic coastline straight through Monday.

For the Maryland/Delaware beaches, humidity remains on the low side as highs rise from the upper 70s today to the low-to-mid 80s tomorrow. Both the heat and humidity rise thereafter, with Sunday and Monday highs near 90 or in the low 90s. Similar conditions are expected at Virginia Beach, maybe just a couple degrees warmer.

At the Outer Banks, highs near 80 and fairly low humidity hang around through tomorrow. More humid Sunday and Monday with Sunday highs in the mid-80s and Monday highs in the upper 80s to near 90.

Cape May comes in with highs in the cool-ish mid-to-upper 70s today and upper 70s to near 80 Saturday. Sunday and Monday trend markedly warmer and more humid -- highs in the mid-to-upper 80s Sunday and in the 90s Monday. -Dan Stillman

Oh, no, Lawrence of Arabia, or maybe Heart of Darkness, weather is about to return. Except for the all-too-few San Diego days we've had, this summer has been excruciating and it still has at least two months to run.

For those recalling the summer of 1980, truly a beast. The 10 hottest days at DCA averaged exactly 100 degrees F. I think (but can't avow) that it reached or exceeded 100 at DCA six times and the number of 90 degree days was off the charts (63??). And this was before GW was part of our lingua franca.

The winter of 1980-81 saw only 4.5" of snow at DCA. Let's hope we do MUCH better next winter.

Meanwhile, re: the World Cup, Viva Espana!! I do envy those football fans in South Africa bundled up at the evening matches.

"Monday, Tuesday & Wednesday reach the witheringly hot category. Poor air quality is likely along with hazy and humid conditions. "

The forecasts I'm looking at show dewpoints in the upper 50's for Monday & Tuesday. Around here, upper 90's but dry seems unlikely, but that's is saying. That's like 25% humidity. If this is true, with this being July 4th weekend and considering our lack of rain, won't half the mid-atlantic be on fire by Tuesday?

I am very excited by the new Daily Digit participation aspect. How would you rate today? ;) also, fellow CWG meteorologist Ann P. was listening to Paul Simon's Rythym of the Saints. Woo!

celestun100 don't stay inside watching soccer while the weather is so nice! ;)

spammy2, I doubt it will be that dry of a dewpoint. I don't think we'll have fires....yet. but I am worried about our continuing dryness...

Celebrate the Fourth of July no matter the weather . . .

The Fourth of July is the celebration of freedom in this nation! What are we free from? Our founding fathers in the knowledge and grace of God almighty set a course away from tyranny of government. Freeing our nation, the U.S.A., from the King of England and his unfair dictates over the people of the yet to be formed United States of America.

The spark of freedom came to the U.S.A. In the following form. When our colonists from England found themselves being taxed by England; without having say about those taxes that were put over them. The colonists fought to be represented; stating no taxation without representation!

The action of the fight gave birth to the United States of America. Patriots through God's grace formed a nation, the U.S.A., from nothing. Patriots standing against and prevailing over the greatest power in the world at that time, England; they brought into existence the U.S.A.

Today where ever we see within our great land, our U.S.A., any government threatening and or taking away our God given rights it is our duty to stand against that evil. The U.S. Constitution also gives us that right to stand against our own government when it comes against the people. We must stand firm against and not let those that would misinterpret our original U.S. Constitution do so. You and I must stand as patriots in this day and every day for the U.S.A. May you have a blessed and happy Fourth of July. VOTE!

Curious what forecasts you're looking at that show dew points in the 50s? Dew points appear likely to be in the 60s Monday and Tuesday.

Posted by: Dan-CapitalWeatherGang | July 2, 2010 11:31 AM | Report abuse

is fed by NWS data (right?)? So, I am going to have to assume there was some sort of computer glitch this morning with that dewpoint data :)

Quick note on the new daily digit poll feature... for those of you who checked it out early on, it now has a View Results link (which was missing before) in case you're interested in coming back to check on results after voting earlier.

I was looking at the graphical forecast:

Mouse over Monday 2pm. As of 3:30pm, it shows this:
