PM Update: Frost Advisory tonight, north and west

By Ian Livingston

Warm-up starts tomorrow then looks to last a while

* Frost Advisory N&W suburbs 3 a.m. to 9 a.m. Saturday (see map) *
* Bastardi knocks NOAA | T.S. Richard update | Cyclone hits Burma *
* Outside now? Radar, temps, clouds & more: Weather Wall *

Brr! It's a little chilly out there, no? After one of the coolest starts this season, temperatures only slowly crawled higher through the day, despite abundant sunshine after some morning clouds. Sustained winds as high as about 15 mph, mixed with gusts to around 25 mph, have added a bit of a wind chill with highs only reaching the upper 50s to near 60. Winds should be dying down as we get into evening while a pretty spectacular weekend is ahead.

Through Tonight: Clouds and a breeze conspired to keep many locations warmer than expected last night. That should not be the case tonight. Mostly clear skies and light winds combine to help temperatures dip to the low-and-mid 30s in the cooler spots to the mid-40s downtown. Some frost is possible across the western and northern suburbs, so be sure to tend to any plants you are eager to save.

Tomorrow (Saturday): A beautiful start to a fantastic weekend. It should be just about perfect for any local activities, including D.C. WeatherFest. Mostly sunny skies, and a light breeze from the southwest, help temperatures rise off chilly morning lows to highs in the upper 60s and low 70s.

Fall foliage: Autumn color continues to increase across the region as we head toward typical peak in the next few weeks in the immediate area. Color has been reported near peak this week along the Blue Ridge and other higher elevations west of the area, with some of the very highest elevations in Va., W.V. and Md. already entering the past-peak phase. As of Oct. 20, the Foliage Network reports high color well west of the area and moderate color elsewhere. Leaf drop is low to moderate thus far.

FIREDRAGON47 - doubtful that is do-able, unless you live downtown. Can you bring in your sensitive plants?

RE: bringing in the tender plants.
No can do. Limited indoor space. 8 foot tomato plants. Huge pots that weigh 100 pounds. Bugs & slugs.
Not feasible...believe me we have TRIED.
Every frost free night after the 15h in this area is a I'll quit the whining now.
Well, maybe one more long dirge tomorrow morning.

I know the forecast states N and W suburbs but then Camden says "unless you live downtown". Does this mean just outside the beltway near National Harbor is susceptible to frost tonight? I also have a few plants but they can be moved into the garage for the night. Better safe than sorry?

pjdunn1, I would not expect that area to get much below the low 40s or 40ish. I think places west, north and perhaps southwest of the Beltway are at the most risk, while places east should bottom out closer to 40. I'm not a frost expert though so if you have time you might want to not take chances.

Thanks Ian!

oooo, sorry pjdunn1.. I was directly responding to FIREDRAGON's comment "Keep Jack Frost away for another week or 3!" when mentioning downtown. I.e. Downtown DC may be able to escape a frost for three more weeks, but frost is likely within three weeks, elsewhere--outside of downtown

Two Qs (not frost-related, but this is the latest blog entry):

1. What's with all the talk about a Dec. 5 snowstorm? Joke? Real? I must've missed the post that started it all.

2. Was it Willard Scott who started the trend of weather guys being media "personalities"? Or was he, umm, "following" someone else?

And one comment:

Walter in Falls Church: You've spoiled us. A mere whale will not do. We expect snow sculpture tableaux this year. Captain Ahab AND the whale! And the ship. And Ishmael.

There's no credible forecast of a December 5 snowstorm and no one who can forecast out that far. It's just that it has snowed here on that date 4 of the last 6 years -- or something close to that.

re: Willard Scott-- I think there were TV personalities doing weather before that. Read Bob Henson's book on the history of broadcast weather if you want more details:

Apologize if this was said elsewhere, but did anyone see the blurb in the LL Bean winter outerwear catalogue? On the last page there was a blurb headlined "Remember last winter" where it discusses the record breaking snow in our area last year. Wonder if they do that regionally- mention the severity of previous winter weather to inspire people to get their winter gear? Smart marketing move, provided you have something big like we did to reference. Just found it interesting.

On another note, I like the winter forecast I heard on NBC 4 this morning- calling for higher than average snow amounts :)

As for Joe Bastardi- unfortunately, his ridiculous tweet earned him even more attention. I chose to ignore his stupidity for the most part, he's annoying at best.

I just brought the plants in. I'm not downtown, and TWC says it's 43 in Michigan Park now. Frost conditions are ideal so I'm not taking chances.

@FIREDRAGON47 -- in California and Florida they turn the sprinklers on very late at night to protect the grapes/citrus fruit when it gets frosty, which happens once every 10 years or so. Would this work?
