PM Update: Cool tonight, near-perfect tomorrow

By Ian Livingston

More chances to top 90 Wed-Fri

While I'd join ranks with those who think today was more than a "7", one thing that kept it from being perfect in my mind was that it's a Monday. Highs are reaching the upper 70s to near 80 this afternoon under a crystal clear and deep blue sky. A bit of a breeze may add a slight chill from time to time in the shade but it's nothing to frown upon. We've got another near-perfect day ahead tomorrow before the heat cranks back up for a few days.

Through Tonight: Give the A/C some more rest (it will probably be needed again later this week) and enjoy this cool evening and night. Under clear skies and light winds temperatures should fall into the mid-40s in the coolest spots to the lower or middle 50s downtown.

Tomorrow (Tuesday): Lots of sun and not much wind equal another amazing day. Highs rise to near 80 or into the lower 80s. Soak it up, there's likely some heat right around the corner.

The only prefect weather would be 3 days of steady rain & cool temps.

Does the contest end of Sept 21 or Sept 22? If it's Wed. and the high is 90, those of us who guessed 63 90-degree days, are toast (although what happens if no one guessed 64?).

Just wonderful today - it feels like March in Arizona! A 44-degree temperature-dewpoint spread; I wonder if that's the DC record.

I agree with VaTechBob, and certainly hope his well isn't running dry.

This drought is awful; leaves are dropping early from stressed trees. Sections of my yard where I haven't watered are complete dust. noted last week that 85% of the state is "Abnormally Dry" or worse, with fully 33% of the state in Moderate Drought and 16% in Severe Drought.

National Airport needs over 17 inches of rain by December 31st to simply get to our annual average precipitation.

Please, LET IT RAIN!!!!!

Since wishing for rain won't accomplish much I figure you might as well enjoy what you get on days like this. There are some hints that tropical moisture may try to work up the East Coast in about a week.. some models have spit out some big rains around the area consistently already. But that's still a way off obviously. That said, it seems dry periods end with flooding so it's not terribly far fetched I guess other than pattern persistence arguing against it happening.
