PM Update: Briefly milder air tomorrow

By Ian Livingston

After a few days of warmer weather, we're right back where we spent a majority of December... chilled and with at least a bit of a breeze. Highs today have made it to the upper 30s and near 40 most spots, but the aforementioned breeze has helped keep wind chills about 10 degrees lower. We'll probably see slightly warmer temperatures tomorrow, but that's looking brief, as cold air seems to enjoy hanging out across the area lately.

Through Tonight: After a mostly clear start, some clouds work into the area overnight. We may even be mostly cloudy at times. Temperatures fall to the low-or-mid 20s in the suburbs to the upper 20s downtown. Winds are light from the southwest.

Tomorrow (Tuesday): Clouds may linger during the morning, but I think there's a fair amount of sun during the day as well. Partly cloudy should do it overall. Highs likely reach the mid-40s, perhaps some upper 40s mixed in. Winds remain light from the southwest early, but probably start to shift to the northwest late behind a weak cold front.

Vegas snow: An unusually cold storm system, fueled by an intense upper-level low pressure, impacted southern California and Nevada last night into today. Snow was reported all the way to the valley floor in and around Las Vegas, Nevada. While no snow accumulated near the Strip or casinos, snow was reported falling there and up to 1-2" fell nearby. Check out an image of snow accumulation on Palm Trees and a video from the area.

Has anyone else seen the the NWS 14 day forecast? Below average temperatures are predicted not only for the next two weeks but also for the rest of the month!

My hope is what didn't happen in Vegas doesn't stay in Vegas. And we therefore get some accumulating snow here. Soon!

JerryFloyd1, I couldn't agree more!

If it's gonna be cold, then bring on the snow. Cold without snow is like cream without coffee!

Hey CWG, I was wondering if anything has changed with the system friday, and accuweather has another big storm next week???

I just noticed that the latest GFS run predicts a strong coastal snow storm on January 12th. Of course, that is so far in the future that we can only fantasize about it, and that is exactly what I plan to do.

The storm threat next week looks more favorable to be conducive to a decent snowstorm around here but it is still way out there. The end of the week storm that the Euro was trying to make big last night still looks like a threat for some snow, but probably not big snow or maybe not even accumulating snow. I think there will be more on one/both soon (next day or so) here.

Ugh. What happened to a warm January and February? Bring on spring. :(

The "forecast through the weekend" link above points to the forecast for last weekend.

Oh boy!!!! This may be our shot at a biggie! I'm not too hopeful about the late-week snow, but the storm that may strike early next week is looking pretty good!

CWG: Out of all the weather models, which is most reliable? Euro? GFS? NAM?

I just logged into accuweather professional and could not believe our 14 day forecast here in Eldersburg, MD. Next Monday Night through Wednesday they are predicting approximately 18 inches for us. HA! If only that forecast would become a reality :) Guess they like the preliminary look of the storm the CWG guys mentioned above.

I'll be countering the snow dreamers with my "anti snow" dance. I don't care if we get another flake. It's nothing but a headache with my 100 mile RT commute. It would be semi tolerable if it happened on a weekend, but I would just as soon have the CWG's early on Jan. Feb. forecast be correct!

Accuweather has 21 inches forecast for Olney next Tuesday. (And they only have 4 inches for DC...)

!^@$&^ Now, unless they shoot this down quickly, I'm going to be sucked right back into snow-hoping.

I don't know what Accuweather uses for the long range forecasts but 21" for Olney and 4" for DC sounds kind of like the afternoon run of the GFS looked. Big storm.. probably rain issues D.C. south and east. Honestly didn't give it that hard a look since it's going to change another 30+ times on that model alone. 8-10 days out.. not much can be figured out other than potential.

thanks for the link ian.

DLO1975, lilymama,
when you say they're "predicting 18" and they "have 21 inches", is that really what they're saying? or is it a 5% chance of that? or are they just reading the gfs?

dang...touchdown stanford...

ian, statisticians,
there must be some "level of certainty" that one could assign to the gfs prediction (which looks to be 5-7" based on that gfs link) for my front yard (MFY) @216 hours out.

do people do studies of these models' accuracy for a given location? what's the chance of that verifying for MFY? 1%? 5%? 20%?
