Central PA Winter 2022/2023

Recommended Posts

MJO has been a fairly big driver in the turnaround to warm the last several days and looks to potentially remain a factor as we get later into the month.

You can see that it entered Phase 4/5 by Dec 22, right when the arctic blast crashed through us… and has spent the last week cycling 5 and 6. Now this teleconnection isn’t instantaneous, but when you consider how strongly correlated to eastern warmth 4-6 are during the winter months.. you can see why our cold snap was cut short when it could have lingered longer without this major reshuffle in the pattern. 

So we’re already into Phase 7 technically, which is a “better” phase… and the pattern responds as such after the Tuesday cutter as we get some Canadian ridging above and knock down the SE ridge.. allowing an attempt at perhaps a more favorable storm track and temps that could still be an issue.. but still doable for snow for us in the right setup. It seems the Jan 6-8 timeframe could present something either in the form of some kind of inverted trough feature with the lingering upper low from the midweek system or maybe a whole other system a couple days later. Hasn’t been much consistency yet on either feature.

MJO forecasts going forward suggest an attempt at getting into phase 8 and maybe 1 and 2 depending on the forecast. I put up the Euro and ensembles for this post, which shows a sluggish move into 8 (GEFS similar) but the extended (monthly) Euro shows a more consise 8-1-2 run as we get from about mid month on. That would be ideal to help set up an eventual return of a widespread below average temp regime to the eastern US, something the ensembles seem to be introducing currently esp beyond D10. In the meantime, we maintain a half decent setup for undercutting storms with higher heights over Canada.. but the potential will get better in time temp wise if/when we get some better support in the Pacific realm (EPO). Right now we’re not really looking at true cold in the pattern initially even with a better looking storm track on our side of the country and a continued mostly -AO. That’s due to the low heights and suppressed jet in the northern Pac keeping an active pattern into the western states, not to mention the aforementioned above normal heights in Canada correlate to significantly above normal temps for that region as well. Once we build some western ridging and ideally reverse the EPO back to negative, we should tap back into a much colder air source. 

Whether or not the MJO does a full blown 8-1-2 run, I’m kind of glad the MJO has gotten this 4-5-6 run out of the way and didn’t stall in those phases in the process. As long as it stays out of there, we’ll have a chance to deliver a favorable pattern for cold and snow. And it appears barring any major changes the next couple weeks that we’ll likely stay out of it for at least most of January. Otherwise, you couple that 4-5-6 with the moderate Nina base state at any point in the next 1.5-2 months and it’ll be more of the kind of weather we’re seeing right now.

Until the pattern has a huge shift we’ll never get real snow outside a weird storm. No more 1-4” clipper systems weekly or other little things that tally up to seasonal total. It’s boom or bust, mostly all bust for the last many years and no end in sight. It is what it is. It’s like a Virginia winter constantly here now.

Some take offense to it being nice outside...not sure why. 

I sort of see it...winter weather (cold, wintry precip) only lasts a few months and it can be discouraging to not have winter weather in the winter. Also, it can't snow when the temp is 60 like it could if it was 20. But to your point, 60 degree weather in January was never offensive - I've just moved on from being frustrated to enjoying these days for what they are...nice days.

So we are basically stuck in the inverse 1960 decade pattern. We had to pay for that insane decade sooner or latter. Going into the winter of 1960 we had 70 years of records saying 55" is the max snow we see only to be hit with 81" then winter of 69'-70' closes out the decade with 75". At the close of the decade and 80 years of official climate records the 1960's held 6 of the top 11 winter snowfall totals ever as well as top 3 years. As of 2022 the 60's hold #1,4,6 ranks in top 10 winters. Only decade with 3. The 1990s have #2,#3, and 2000's have #8,#9.

Further going back 80 years from end each decade no decade ever accounted for so much as 3 of top 10 winters compared to the 6 the 1960s did. Damn hippies

Also, there is a difference between stating obs and rooting for something.

Our good & great Winters have long breaks.

I could go Winter by Winter to give example after example, but it’s probably no use because some people have no memory or sense of history.
All that matters to some people is what happened 5 minutes ago! History just must have started last year!

Thanks for this post!

Lol, some people on here think that we must have used to get 10 feet of snow every year around here. These same people think it should snow from Halloween to Easter non stop every season…just like the good old days…lol!

This. Time to accept we are living in different times and lower expectations.

Lol….I promise it will snow again.

We are only a few inches below normal snow to date…we can get caught up & then some in a hurry.

I accept that we have some good snow years & some bad snow years & some average snow years….just like we always have….& we always will.

Who in this thread thinks like this? I'm not reading any of that.

My weather memory is pretty good- believe me, I remember some very lean snow years back in the 70s and 80s.

Lol…certainly not you…

read a few posts back….

Thanks for pointing out that we have had lean snow years several decades ago. My point is that some people apparently have forgotten and think this is some new phenomenon.

thanks as always Mag.  I'd also add that if you look at other tellies as we approach mid month, AO and NAO look to add credence to you suggested better look as we get beyond first week of Jan.  PNA slightly pos suggests that ridging should be out west, but I'd also think a more flatter look than a big ridge/trough look for the conus. 

We really did miss out on a nice period before the holidays and hoping the luck of 2023 is a bit better for us.  Clock is now tickin....

A slow move through MJO phase 8 and 1 in the heart of Winter from mid January onward would get this Winter going in the right direction. The GEFS & Euro MJO forecast are both trending in this direction.

The 30% chance of showers has led to three straight hours of rain here. 

Yes, brutal today with unexpected rain!

We went to walk around Little Buffalo state park up in Newport. The temps were nice in the mid 50s with clouds. The second half of our trail walk around the lake brought the unexpected rain showers!
