Oh, my ... NWS boosts forecast to 20-28 inches

2003 snowstorm Baltimore 

 

UPDATE: Let the wild rumpus begin. There are flakes in downtown Baltimore at 11:05 a.m. Meanwhile...

The forecast escalation continues. Now the National Weather Service has issued a new Winter Storm Warning that predicts snowfall across the region between 10 a.m. Friday and 10 p.m. Saturday in the range of 20 to 28 inches.

As we've said, a 28-inch storm would threaten the all-time (since 1883) Baltimore record snowfall of 28.2 inches back on Feb. 16-18, 2003 (photo). It would also, of course, eclipse the 21.1 inches that fell in December. Some locations could well see more than the airport. Some forecasters have an upper end to their predictions well into the 30-inch range.

Here's part of the Winter Storm Warning:

 * TIMING...SNOW WILL BEGIN MID-MORNING...AND WILL CONTINUE THROUGH
  SATURDAY EVENING. CONDITIONS WILL DETERIORATE RAPIDLY THIS
  AFTERNOON...WITH HEAVIEST SNOWFALL OCCURRING FROM SUNSET THROUGH
  SATURDAY MORNING. THE MOST HAZARDOUS CONDITIONS WILL OCCUR
  TONIGHT.

* VISIBILITIES...THE COMBINATION OF HEAVY SNOW AND STRONG WINDS
  WILL REDUCE VISIBILITIES TO BELOW ONE-QUARTER MILE...PRODUCING
  NEAR-BLIZZARD CONDITIONS TONIGHT THROUGH SATURDAY MORNING.

* TEMPERATURES...HIGHS IN THE LOWER 30S TODAY. TEMPERATURES WILL
  BE IN THE MID TO UPPER 20S TONIGHT AND SATURDAY.

WeatherBlog readers report that the snow is already falling (at 10:15 a.m.) in the Beltsville/Laurel area. Also in Columbia. "Light snow" reported at 11 a.m. from BWI. Downtown Baltimore remains flake-free. For now.

Here's the latest forecast from Sterling. Here's AccuWeather.com, and here is Foot's Forecast.

"There are flakes in downtown Baltimore at 11:05 a.m. "

OK. But what about the snow?

FR: That, too.

Unbelievable. Meanwhile, up here in New Hampshire, my son's cross country skiing team has lost two meets for lack of snow.

FR: Come and get it!

foots saying 24-36

This nut is saying 4 feet of snow... http://www.1bal.com

FR: Let him name his source. Meanwhile, if you add up the lower ends and then the upper ends of the ranges posted by the NWS on the current BWI forecast http://bit.ly/8YjmGj , you get 21 to 33 inches.

Snow! Help! Ouch! Cold! Can't catch breath! End is nigh! No whole milk! Sold out! Only skim! No! Bad! Won't! Bread! Cocoa! Snacks! Super Bowl! What? Run! Help! Wicked city! Old Testament-style punishment! Wrath of God! Wrath of nature! Wrath of Khan! Man vs. Nature! Man vs. Man! Man vs. Self! 2012! Panic! Doomed...all of us! Must evacuate town...before...too...late!Hat! Precipitation! El Niño! The Mayans! Cold front! Low pressure system! High pressure system! Voter fraud! Warm front! Meteorology! Barometer! What? [Keels over.]

Yes Frank,

There is snow in downtown Baltimore. Lexington market is over run with last minute bread and egg shoppers..I am at work but I will very soon be heading home to Highlandtown. Be careful everyone

L.

NWS now at 20-30 inches...

light snow falling in Easton on the Eastern Shore - let the fun begin!

Enjoy the snow. Meanwhile, I'll be at my son's baseball practice tomorrow. The forecaster says to expect sun and temperatures in the 70's here in Orlando.

FR: Hurricane season is just around the corner.

Is it warmer this afternoon than the forecasters thought? It could snow for days, but when it's 38F like it is right now in Bel Air, it's not going stick. Maybe I'm a skeptic, but unless something changes with the temperature fairly soon, this is going to be a rainy bust.

FR: Patience.

It's been snowing here in East Baltimore since 11:00 or so, but the temperature is still above freezing (down to 36 degrees at 1:30), so nothing has stuck yet.

Is it ever going to stick?

Count me in the "dud" camp. It's been snowing for several hours in Elkridge, not a single flake is on the ground, it's all melting.

My prediction:

2" - 6" of slush tonight after dark, then done.

FR: Just checked with Jared Klein, a meteorologist at Sterling. He said they have 2 inches there, and promised the forecast was on the beam. "We only expected, probably, up north during the daytime, 3 to 4 inches. We still have a couple of hours for that. It's coming. It's gonna take a little bit of time. Things just got started, and once we get the heavier snowfalls currently over central and southern parts of Virginia, it doesn't matter what the temperature is. It's gonna start sticking."

I was wondering if you have statistics on how many times the Baltimore/DC region has had 2 storms in the same winter that produced more than one foot of snow each?

Thanks.

FR: That was in our main snow story today. We've never had two 12-inch storms in one season. The closest we came was in 1996, when the 22-inch January storm was followed by a 10-incher later in the season.

I was looking at your top-20 chart of snowstorms and I see in 1899 there was a storm in February with 11+ inches followed a week or so later by one with 21+ inches.

It's about climate change, earth catastrophe and our planet as we lives in.


Thank you.
