Only a few more weeks and none of this will matter. The agony is almost over. I think NYC south is done. Even if things improve later in March climo works against them in a big way but SNE will do well as long as the blocking plays out as forecast.
-
Cold usually wins out this time of year but the Nam showing the warmth hints that perhaps it'll get north of us.
-
December and March are completely different. For one you don't need a +PNA in March
-
2nd half of March will deliver in SNE. NAO response + rapidly shortening wavelengths equal snow potential. There's already hints of this in the LR OP runs.
-
It is good that the west coast is benefiting from all this, they really needed it. Incredibly drought conditions could be reduced to nil in California when all is said and done which would've been unthinkable a few months ago. The downside is the growing drought in the plains, which is not good given that's our crop growth zone. We need big improvement there
-
A couple more ticks north and 70s get into NYC for Thursday. Could be a wild temperature swing
-
It's scary how easily we're putting up 60+ temps in February. That's like seeing multiple 90s by mid April.
-
Next season
-
Where's Brooklyn to tell us how good the GEFS looks
-
The only time the RNA won't be as damaging is by 2nd half of March due to wavelengths but by then you're fighting climo big time. Which is why I think it'll just be a chilly March 15 till early/mid April. NAO could stick around for a while so hopes of a warm early spring are very unlikely
-
What a fun rollercoaster that would be. 30s on Wednesday to low 70s Thursday and back to the 20s on Friday.
-
I think we're too far south to benefit. SNE could do well. Unfortunately I see us getting stuck between the very warm, sunny pattern (60s & 70s) and the cold, wintry one further north. So a lot of dreary 40s & 50s. The GFS has a very early spring backdoor looking pattern for us with a nasty cold tuck. That would only worsen under a -NAO blocking pattern. The 12z GFS is a perfect illustration of what I mean.
-
This won't cut it for March
-
The "blocking" shown on the EPS for March may only get us to near normal which by March is too warm for snow. I'm 50/50 percent sure we won't get any more snow this season
-
Hints of a PV press for the 23rd. Wouldn't be surprised to see that trend south and lead to icy conditions for northern areas
-
Except we're still barely BN as cold anomalies remain west. Additionally all it takes is a stronger -PNA to pump the SE ridge and we stay AN. I do think this will lead to a cold 2nd half of March into April as wavelengths shortern but by then it'll likely be too late for anything meaningful
-
If the arctic cold pool didn't shrink then this March would play out like 1956.
-
Yes things have warmed considerably since then. Looks like an east based -NAO too with a neutral PNA. Still a better analog than 2018 though
-
You can already see how that would set up a cold early spring with the shorter wavelengths. Not surprising that CFS shows a cool April.
-
Do you have a composite map of March 1956
-
Yes but you can see higher heights over Alaska and western Canada in March 2018 If you're just relying on the -NAO then that could easily link with the SE ridge under a strong RNA pattern. This is not a 2018 look. SE ridge would likely correct stronger. At best you can get a gradient pattern.
-
Yes that really keeps heights low in the 50/50 zone and staves off the southern ridge
-
GEFS show that as long as there isn't a ludicrously deep trough out west that things wouldn't be so bad after the 24th
-
Yeah but we can still get a snowy season with a higher baseline.
-
Maybe a nino in 23/24 will do the same. It certainly can't get much worse.
