Major East Coast Storm Gets Underway
Eastern US Weather Forums ^ | Various: NWS/HPC/NOAA

Posted on 02/27/2005 11:13:44 AM PST by nwctwx

A major to possibly historic snowstorm is now forming in the Gulf of Mexico. This storm will track northeast along the East Coast Monday and Tuesday bringing very heavy snow and near blizzard conditions to many. The exact track is still uncertain at this time, but the big cities along the megalopolis could be in for a very large event. I put together a few maps to track the system, and will add more shortly.

QPF DISCUSSION

...ERN STATES...

WILL KEEP THIS SHORT AND SWEET. FOR THE MOST PART THE MANUAL
DAY1 QPF OVR THE ERN U.S. STRONGLY REFLECTS THE GFS MODEL. THIS
MODEL HAS GOOD CONTINUITY NOW FOR THE PAST FEW MODEL RUNS AS
OPPOSED TO THE NAM WHICH HAS BEEN ERRATIC AND FOR THE MOST PART
WRONG WITH ITS SCENARIO. THAT BEING SAID THE CURRENT GFS IN THE
EARLY PART OF ITS 1200 UTC FCST CYCLE DOES NOT HAVE A GOOD HANDLE
ON THE DEPTH OF THE GULF LO. TO WHAT EXTENT THIS WILL IMPACT ITS
FCST IS UNCERTAIN. ITS FARTHER WEST SFC LO SOLUTION AS COMPARED
TO THE UKMET AND THE ECMWF ALSO DOES NOT LEND SUPPORT TO A
HIGHLY CONFIDENCE FCST. IN ANY CASE...USED THE GFS FOR THE TIMING
OF THE PCPN ASOCTD WITH THIS SYSTEM WHICH HAS TRENDED SLOER FM
PREVIOUS RUNS. THE ONLY CORRECTION MADE TO THE GFS...WHICH IS
IMPORTANT FOR SNOW LOVERS...IS THE ADDITION TO ITS QPF ON THE NW
SIDE OF ITS PCPN SHIELD. BELIEVE ITS CURRENT FCST DOES NOT STGLY
REFLECT THE TRACK OF THE MID/UPPER LVL CNTR AS DEPICTED BY ITS OWN
MASS FIELD FCSTS. LATEST STLT AND RADAR ALREADY INDCS THAT IT HAS
MISSED THE PCPN DVLPNG OVR THE UPPER TN VLY TO THE NORTH OF THE
MID LVL CIRC AND SUSPECT THIS COULD CONTINUE. PLEASE SEE LATEST
WINTER WEATHER PRODUCTS FOR FURTHER INFO CONCERNING FROZEN
PCPN.

Thanks for the offer - her school is on Edwards Mill Road and I work at RTP. It took two hours to get to her school and then 8+ to get through Wade Avenue, Ridge Road (I-440 was stopped entirely), then a short jaunt on I-440 to Six Forks Road, Sandy Forks Road, then Falls of the Neuse Road to the church where I finally parked after all roads into North Ridge were blocked off by the police due to the number of accidents!

The NWS is currently predicting 4-8 inches here in southern NH (never mind Boston, where rain will probably cut down accumulations). This is boringly normal, not "historic".

Maybe boring in your backyard, a low as deep as this is supposed to be is not normal though... maybe once every few years. Then again, when I made a post about a coming blizzard 2 days before the late Feb one some people here called me crazy. ;)

I visited the site. I found the threads and comments disjointed and only for insiders. But thanks for the maps you posted here. I am degreed, but retired and removed from today's meteorology. I read Caribou, ME discussions and spot snow measurements from my cove.

It's really wild today, but is usually an excellent place for information... we have several big name mets posting there from time to time, but it is a bit of an insider thing at times.

We have several excellent posters from Maine, always looking for more..

Off-topic kinda: what do you think of NOAA officially naming "El Niño" as the cause for the 2004-2005 California storms?

...how deep would 9 feet of water be if it were in snow?

some folks use 1" rain = 10" snow as a rule of thumb. Really depends on what kind of snow it is: light and fluffy, or what they call 'wet snow' which can be damn near like porridge. The former might give a 1 : 12 or 14 ratio, the latter might be 1 : 5 or less.

Using the rule of thumb, you'd have 90 feet of snow!

Makes sense, I believe many have thought there was at least a week el-nino all winter. It has not been the typical set up, but the results have been similar on the west coast.

Reason for the question was the Friday article , in the Los Angeles Times, regarding Opids Camp above Pasadena where this rainy season, has accumulated 107 inches of rain..., they get some snow also....it has been wet out here.

I'll tell you what...if this really turns out to be a "971mb Low", then the NWS forecasters (who've clearly been pulling their hair out over the divergent computer models on this storm) are going to be "all wet" (or maybe that ought to be all white), as I'd expect a bit more than what they're predicting from a storm with a center below 29 inches of mercury.
