FORECAST IN DETAIL

Classic fall weather dominates the forecast through the weekend. Crisp chilly nights and mild sunny days provide the incentive to go out and take in some of the rapidly coloring leaves. Rain chances are nil through Sunday as high pressure settles in. A spot or two of frost in the far western suburbs can't be ruled out Friday night.

Today (Thursday): Sunshine greets the day in style, although these days that appearance isn't until about 7:30 am. Temperatures scoot fairly quickly up through the 50s and 60s during the morning hours. However, with quite cold air overhead the surface heating leads to a quick upwelling of clouds around noon. That puts the brakes on our temperature climb with mainly upper 60s for the cap. Ten to 15 mph breezes come from the south but shift to out of the west by afternoon. Confidence: Medium-High

Tonight: The clouds are gone before sunset and winds quickly die down. Evening readings aren't so bad with upper 50s to lower 60s. Lows fall to the low-to-mid 40s overnight. Confidence: High

Keep reading for the forecast through Monday....

Tomorrow (Friday): The chill in the air takes a little longer to abate despite plenty of sun all day long. Highs struggle to the lower 60s. Winds from the west at 10 to 15 mph make a jacket a welcome addition to the ensemble. Confidence: High

Tomorrow Night: Skies are crystal clear which allows the full moon (Hunters Moon) to shine brightly. Calm winds allow a quick retreat for temperatures. The western fringes of the suburbs closer to the Blue Ridge than D.C. could have some pockets of frost. Most areas bottom out in the mid-30s with low-to-mid 40s downtown. Confidence: High

A LOOK AHEAD

Saturday borders on perfection. Brilliant fall sunshine and a return of light breezes from the south allow for a rapid warm up. Highs in the upper 60s to lower 70s should encourage bikers, hikers and dog walkers to scrap the jackets. Evening readings hold on fiercely to the 60s with 50s reserved for the late night crowd. Lows are only mid-to-upper 40s in the burbs and lower 50s downtown. Confidence: High

Sunday is even better on the temperature front with highs likely to be all 70s! The only thing marring this day should be some thin high clouds coming off a blessedly slow moving storm in the Midwest. Highs for the day run about 10 degrees above normal (mid 60s). Evening readings only slowly slip into the 60s as clouds increase. Confidence: Medium-High

Monday starts out in the 50s but with mostly cloudy skies temperatures climb at a more leisurely pace. Still, highs should make the upper 60s to lower 70s without too much work. Showers begin to creep over the Appalachians by early afternoon but should spare the area until evening (30% chance). Confidence: Medium

FIREDRAGON47 - isn't it about time for first frost though? Cumberland hit 35F before sunrise this morning.. all seems normal and on-track for average chill :) right? [I don't want frost yet either, though haha]

Yes it's time for frost. In Centreville we usually get hit with light frosts starting in the middle of Oct. The Grim Reaper everything-is-so-dead frost will be a little later.
Hopefully MUCH later. It's hard to say goodbye to fresh basil & jalepeno peppers right outside the back door.

FIREDRAGON47, wow, nice gardening there. I hope you can check with CWG (for overnight lows) and move those susceptible plants inside until the growing season fully ends next month!

It's far too early for the cricket-killer frost right now, though the cricket population seems to be down a bit...due to cooler weather and alternate dry/wet spells.

Trending on the weather boards right now: NOAA's winter outlook & commentary thereon.

There's also apparently an "Invest 90L" somewheres out near Cape Verde, though it's awfully late for Cape Verde storms by now.

I am sick of the sounds of crickets AND cicadas! GO AWAY, NATURE!! (Yes, I'm a curmudgeon!)

sigmagrrl, I think they will soon stop chirping as our average daily temperatures get pretty darn cool!
