Notice the TN Valley screamer coming this way on the LR GFS models as well. Fun times ahead. If I was a betting man- a foot of snow on the ground by Groundhogs Day. Where this a pattern change- watch out and this will be a huge pattern change. Latest MJO trend is backing down...much less amplification and fast return to cod.

JTA66 Posted January 15, 2020 Share Posted January 15, 2020 Too early to say for sure, but certainly having flashbacks to last year when the really good looks in the LR started to get muted as we moved forward in time.

Dec 19, I stated that winter would return between 1/5-8/2020. It indeed did with several light 1-2 inch snows. The we got this brief warmup this weekend which was expected. The quote above was made on Christmas Eve. Looks like a significant overrunnning event on Sat-Sun this upcoming MLK weekend. The models have been consistent with a 6-12 inch amount. I would say at this point this amount looks reasonable with an inch or so of sleet topped off with a freezing rain/frizzle crust on Sunday morning to make it a real bitch to shovel. Snow blowers will be worth their weight in gold this weekend. The potential for lot of heart attacks exist as many will have over exerted themselves from not being used to shovel this heavy slop. I also stated that there would be a foot of snow on the ground by Ground Hogs day. Where is your winter LR forecast posted that is on cue as you said? You might be the only forecaster to have nailed it outside of Tom. Would love to give you credit where credit is due. Is the 6-12" this weekend part one of the MLK weekend back to back storms you forecasted? 1 Link to comment Share on other sites More sharing options...

bluehens Posted January 16, 2020 Share Posted January 16, 2020 Another storm 15 days away. Wash rinse repeat. Just have to think this isn’t our year. Too many LR head fakes already and my guess is it continues. One thing I have really taken away this winter is how much model output is driven by MJO and how difficult it is to get the MJO right. 1 Link to comment Share on other sites More sharing options...

So whether a longwave in china is different or a blob of HP over N Canada, the truth is the apparent real weather patterns at the surface are repeating ie storm cuts to GL and secondary redevelops a hair too late, a storm is too far off the coast, a storm slides right over us, or we have a good track in between cold shots and mix or rain. I dont see this changing...unless there is a hemispheric reshuffle of the overall background state tellies or we somehow fluke into something late in the season as everything gets convoluted during seasonal transition and HL actually appears in some form besides progressive/transient.

JTA66 Posted January 16, 2020 Share Posted January 16, 2020 I will say I don't recall anyone forecasting an epic winter this year. But most did say something along the lines of, "if nothing else, this winter should be better than last year." To the point you made yesterday Ralph, last winter WAS BETTER than this one so far. If nothing else, we had the November storm. Still, it's only 1/16. I'm not expecting a huge turn around, but maybe we can luck into a few fluke events so it's not a total fail. 1 Link to comment Share on other sites More sharing options...

Some of my LR posts were on Facebook in my closed group and never made it on here as I have been reluctant to post here. I will try to place them all on this site in the future. Yes, this storm for saturday was the predecessor for a much larger one later next week that I have been calling for. This typically happens in this type of pattern change as 40+ years of weather experience has taught me and not just hugging every model run. While this mornings LR models are spitting out 24+ inches, I certainly say that is the outlier right now. I am still holding firm to at least a foot or more of snow on the ground for the varmint to see his shadow on Feb 2. Just be prepared for bone chilling temps the next few weeks compared to what we have seen thus far this winter. Link to comment Share on other sites More sharing options...

Not here in Philly. That period was the nightmare of the "ice storms". I think I literally counted around 17 individual events IMBY that I was white-knuckle commuting through to/from work, starting some time in December (and there had been a "rain every couple days" thing going on antecedent to that so it seemed inevitable). It was to the point where the tristate area had run out of salt and there were caravans of trucks that eventually came down from NY state to help with the shortage/unavailability of both road salt and consumer ice melt products. People were left with throwing sand, kitty litter, and table salt out on their walks. I remember the worst one that first week of January (the 7th I believe), when I had to go on a work-related trip down to Baltimore (by Amtrak) where I had planned to drive to 30th St. station early morning and park there to get on the train. And on my way down, I intended to go on I-76 (that I generally avoid) figuring it would have been better treated as a "primary (interstate) route", than my normal downtown route (the river drives). But literally, just as I approached the entrance ramp to I-76, the traffic report indicated that PennDot was about to close 76 because of the ice build-up, with cars/trucks getting stuck on the ramps, unable to go up or down them. So I was able to bypass that and continue on downtown along one of the river drives, and ease on into the station parking lots. Meanwhile I-76 was eventually completely closed with hundreds of cars and people trapped there for over 8 hours. While in Baltimore, I managed to find and bring home 3, 5lb bags of Halite in my suitcase that I handed off to my mom for her sidewalks. She ended up having the only portion of sidewalk on her block that was "clear and dry" to the cement. What was interesting too about the '94 ice storms was that many of the residents of the western suburbs learned the hard way that Rte 202 was considered a "secondary" route, meaning "delays" in road treatment while the "primaries" (interstates) were worked on as a priority... and the outrage was fierce. Forget if you live in the city proper, where the "main thoroughfare" streets were considered "tertiary", so good luck... So here in Philly in '94, it wasn't the snow depths that upstate/Lehigh Valley may have had, it was the nightmare of the ice. It was enough to uproot and pull down an old cedar tree between my mother's house and her neighbor's house, and when it went down, it extended some 50ft across the front yard abutting the house, and halfway into the street, just missing the neighbor's car. And as a historic note not mentioned for Philly - that 1994 winter was the last time that Philly recorded a below 0 temperature (recorded as a -5F at KPHL January 9, 1994). It's gotten close a few times with 1s and 2s and 3s but so far all above 0. 1 Link to comment Share on other sites More sharing options...

Intermittent precip/lull between the WAA band and the batch trailing behind. Farther North the shorter the lull. In the SE part of the state...c-2" snow then a .25-.5" sleet a little less extreme SE counties. Just enough to make travel slick. Link to comment Share on other sites More sharing options...

Cannot explain why except that is when the weather pattern changes most often occur in this time period. As far 94 goes I fully agree that the constant barrage of ice storms on top of existing snow packed roads were major issues as they serve to complicate by creating glaciers that seem to never melt.

"Glacier" is the perfect word for it Not since the winters of '76 & '77 with their frigid temps (and their glaciers), did we have so much ice here. I remember back in '77 where I lived (lots of hills like where I am now) where the buses could not get up the hills due to the ice (with water on top), so they made people (like me) get off the bus and walk up to the top of the hill and get back on again. Those were the years when long johns became really popular again down here. It was a big change from the early '70s with the snow drought (not unlike we are seeing now). And like '76/'77 eventually heralded the blizzard of '78, so too did '94 eventually herald what happened in '96. Link to comment Share on other sites More sharing options...

The ice was 2 feet thick I believe. 1994 I call the ice winter - icicles hanging in trees for days, and my yard looked liked it had 3" of liquid ice poured over it.

Now what I remember and what actually happened may be two different things, but... Growing up in the 70's and 80's, it seemed every forecast for a sizable storm included the words "blowing and drifting". And I remember it seemed very cold air masses would follow those storms. For instance, if yesterday's storm occurred 40 years ago, it would be in the teens today and everything would be a frozen block of ice. As great as 2009-10 was, I don't recall it being particularly cold after those storms. Even the blizzard of 2016 didn't feature any remarkable cold afterward.

I remember getting blank maps of the US and having to hand draw fronts, isotherms, isobars etc on the maps and turn them over to my professors to be graded on accurate they were based on the weekly plots by NOAA from Md. Yes, hand drawn using data generated by balloons etc and airport weather stations. Yes I admit, I am old fart but I would not have any other way. Weather history plays a vital role and I still heavily rely on it. Many of todays meteorologists use weather history primarily for daily and annual comparisons for extremes. When I was first predicting long range forecasting for my family and friends, I used past weather history in determining a more accurate daily weather forecast. We have come a long way in the past 40 years. Have fun with the video Anybody else going back and reviewing their first winter after they were born? 69 was a decent winter for me mid Nov, mid Dec, Jan lul(of course) then it rocked in Feb and March.
