stormy

GFS 100 miles south of the benchmark. Plenty of time to adjust. I had feared south and east suppression, it verifies. Some had feared a runner which is 60 days ago.

Preponderance of evidence at 180 hrs. suggests a high probability of a Miller A storm on the east coast early to mid next week. Credible details are impossible at this range. Confidence should be much better by Saturday. Regarding the GFS snow maps. If the storm brunt reaches north and west to our latitude, heavy snow would be possible from the Blue Ridge westward through the 81 Corridor into the Potomac Highlands. Significant accumulations (more than 3 inches) would be unlikely for the 95 low lands.

18 inches in my back yard on the 22'nd by the 18z GFS. WOW!!!!!! What a hoot!!!!!!!!!!!!!!!!!!!!

For you. I'll take the 6 inches of white-stuff.

A few miles north of Waynesboro, 12:38- moderate snow, 30.8 F., one half inch

Hello Neighbor! This should be an elevation event. I'm telling my many fans to expect less than 2 inches below 2000 ft and 2 - 4 inches from 2000 - 4000 ft. elevation. Its plenty cold for snow at 850mb at -5 C. Surface temperatures are very marginal for daytime accumulation in mid March at 32 - 35F. unless rates are heavy. Southward suppression of qp could be an issue.

I agree with you 100% ................. Nothing more need be said. Thanks for your wisdom!

That would be wild for late March with the plummeting temperatures following! Nice to look at on paper.

After a very low snowfall winter many are in a depressed state of mind and seemingly believing that we have reached an era of snow drought that we will probably have to learn to live with. That is nonsense that no reasonably intelligent person should believe. Average annual snowfall patterns rise and fall the same as temperature patterns rise and fall over decades or longer. They have been for hundreds of years. An unusual anomaly occasionally occurs with a very heavy snowfall winter as 95-96 or 09-10 but often a longer anomalous period occurs. In D.C., 2011 - 2019 was the lowest near decade of annual snowfall in 120 years at 12.9 inches. Boston had it's highest near decade during this same period with 54.9 inches. During the previous 10 years from 2001 - 2010, D.C. had it's snowiest decade since the 1960's at 16.8 inches annual average. D.C. had it's snowiest decade from 1961 - 1970 at 23.7 inches. At nearly the same latitude, Dodge City, Kansas had it's least snowy decade during the 1960's at 14.9". With a flipping Enso. condition next winter we have a reasonable shot at a flipping snowfall pattern.

The signal on the GFS at 1 pm opened the door. My gut feel about this may possibly bear fruit.

The GFS trend that I referred to early this afternoon continues. It now has significant snow up to Martinsville Va. Sunday night.

GFS trends toward the ECM at 135 hrs.. Not a cave but a trend.

I do not claim to be an expert, but this is the third La Nina year. That is very unusual. I believe the models are trying to assimilate a pattern without La Nina and the resultant persistent SER. This would be a tremendous winter without La Nina.

I am amused regarding the frantic following of models. They are as corrupted as the humans who create. Self proclaimed experts make proclamations nearly every run only to to proven wrong 6 hours later, but nobody remembers. We are running out of time except with elevation. Next winter will please as snow droughts are not successive.

It ain't over till its over, but this is expected as the GFS and GEM have been feeling height rises in the Atlantic. Just more of a long term pattern that encourages cutters to the OHV or Lakes because of the SER.

The persistent 500 ridge over Cuba is the boss. Will it relax enough to allow the NAJS to settle south thru the MA during March? Short and sweet in a capsule.

Ive been expecting a change for some time now in late Feb, or March. Is this it? That is the $64,000 dollar question. It is very nice to witness the GFS and ECM both looking at a same general opportunity timeframe 10 days out.

A definite improvement over 00z for the ECM. 500 energy tracks 50 miles farther north as it crosses NC. The weenie map gives me 6 - 7 inches compared to a half inch at 00. Hopefully, this is the beginning of a trend for everyone. If we can only drop those thermals surface and aloft.

Considering the past 45 days over Va/Maryland I must agree. This threat as advertised by the 18z GFS will not verify because intensification will be insufficient to produce the needed amount of dynamic cooling for snow outside of higher elevations if at all. Please Dear God, let me be wrong. This pattern must break at some point.

The pattern will shift in late February or March. Will it be in time for the coastal plain like D.C. or will it only sweeten the higher elevations out west. I have received many April snowfalls of 1 - 8 inches in the past 60 years. Is this the year for 8 inches on April 7 like 1971 or will we measure the winter on Easter Sunday, April 9.

Does anyone have a site that gives historical data on Nino types for the past 50 years or more year by year. West based or East based.

You are 100% correct!! Some people pray for El Nino but in truth a Nino can be disappointing for snow in our region. Looking at 3 snowy winters in my area during the last 65 years, 2 were El Nino's and 1 La Nina. 1957-58: 50 inches snow was a +1.8 Nino. 1986-87: 52 inches snow was a +1.2 Nino. 1995 - 96 at 66 inches snow was a -.9 Nina............ Least snowy 1991-92 : 3 inches snow was a +1.7 Nino, 1972-73: 5 inches snow was a +1.8 Nino. Be careful what you pray for.

As I said yesterday, January has been a dry month for much of our region. The latest models are now continuing that pattern into February with both snow and rain for many areas.

November and December were wet for me. January has been very dry. Only 51% of normal first 27 days at 1.30".

In reviewing the comments of the last 3 hours I see quite a few comments about the winter Enso condition and snow. My general opinion about La Nina has been that my area is more likely to be dry winter or summer. I have liked El Nino in the winter because of an encouraged robust STJ and Virginia often being on the north cold side of systems. Looking back at snow drought years the past couple of days has surprised me. Two out of 4 significant snow drought years from the past 50 years have been El Nino's. A week ago I would have bet that all 4 snow droughts would have been Nina's or neutral. 1972-73 DJF +1.8 Nino 5 inches of snow, 1991 - 92 DJF +1.7 Nino 3.05 inches of snow Last winter was a DJF -1.0 Nina, yet I received above normal snowfall at 28.50 inches. These stats throw some cold water on the idea of always better with El Nino, at least for the Central Shenandoah.
