PM Update: Cold tonight, seasonable tomorrow

By Ian Livingston

Today's highs in the upper 40s to near 50 felt extra chilled thanks to sustained winds as high as 15-20 mph with some gusts near or past 30 mph. But, when you think about all the cold and wind the past few months, it's not too bad out there. We've got a cold (for the time of year) night ahead, and a fairly decent day on tap tomorrow, but enjoy it while you can, because more clouds and rain are penciled in on the schedule as we head into and past midweek.

Through Tonight: Gusty breezes of earlier dwindle into the night. Mixed with mostly clear skies, that sets the table for some decent radiational cooling. Lows should range from the mid-20s (perhaps a low 20s somewhere) in the suburbs to around 30 downtown. This is about 5 degrees below "normal" for this time of year.

Tomorrow (Tuesday): Lots of sun, and not a lot of wind. Overall this is a fairly classic early-March day, with some increase in clouds (mainly high level) throughout. Highs should shoot for the low-and-mid 50s, which is near or just above average depending on location.

Northern New England Snow: Heated local debates about yesterday's snowflakes aside, the storm system that gave us lots of rain has dumped on northern New England, where some places are nearing all time seasonal records. As of 1 p.m., with snow still falling, Burlington International Airport in Vermont had recorded 23.3" of snow -- the largest March storm and one of the biggest ever on record there. Even locals across the area who are used to big storms are calling it "epic." How much is epic? Check out the totals from NWS Burlington!

I'm from Vermont and it's been interesting watching the Facebook updates from people who are saying they are snowed in for the first time ever. Originally they were only suppose to get 12 or so inches but this is well beyond that. On the flip side, they plan to have all the major roads plowed by tonight - granted they have less major roads and these super cool double plows that can do two lanes at once, but that's still pretty efficient.

hereandnow1 - For snow storms on the East Coast, I think 30" is way too much to handle for anyone. It is around the maximum produced by these types of storms, climatologically speaking on the East Coast-- but I suppose VT hasn't been in the "sweet spot" for a snow storm in quite some time. This was their turn, apparently!

wow! i guess those vermont forcasters didn't have to deal with the challenging issue of predicting if/when the change-over to snow would happen.
----------------

closer to home, some have suggested removing the concept of "accumulating" from the SPI, saying it's the snow that matters - not whether it accumulates.

but it DOES matter whether the snow accumulates. snow in the air is beautiful, but an entirely different animal than snow that sticks and that you can play in (or for you "adults" out there, snow that affects your commute or inconveniences you in some way). so... maybe we need to rethink the "+" part of the SPI.

there could be an SPI number for any snow chance - whether it's predicted to stick or not. if the snow is predicted to accumulate, the number gets a "+" next to it. if it is predicted to accumulate over a certain amount it gets a "++", etc...

It's Vermontageddon!

I was on accuweather looking at the 15 day fircast and they are forecasting significant snow for the 20th. Do forecasts that far off have any accuracy whatsoever.

thought it was interesting to notice how just a few hundred feet of extra elevation made a big difference in snow totals last night. Winchester, Martinsburg, and Hagerstown didn't seem to get much over a 1/2 inch but places just a tad higher like Bluemont, Paris, and Linden got 2-3"+ Would have been a neat hike up on the northern Virginia AT today.

Byzantium1453:

Accuweather calling for rain and 47 on the 20th...so forecast has already changed. So short answer to your question: no

Walter: I totally get your need for accumulating snow! But here's where I was coming from on the SPI and "accumulating" issue (and CWG, maybe you can shed some light on this). I've always wondered if falling snow gets collected on a chilled surface for measurement, or if it's only measured if it accumulates (by sticking a ruler into the pile later). If it's the former method, doesn't falling non-accumulating snow still count as snowfall?

Thanks.

@walter-in-fallschurch

Thanks for the suggestions on the SPI. We'll take them under consideration during the offseason when we decide what tweaks to make.

petworthlad,
i think there's some kind of wood platform they measure it on - probably equivalent to what you might measure on a picnic table. i don't know how long it has to last w/o melting in order to "count".
