Just in general: Nina= Aleutian ridge = -PNA
Nino = Aleutian low = +PNA
Plenty of other variables/modulators though, so these teleconnections are far from locked in or static. With the overall increase in ocean heat content, this stuff becomes even harder to predict.
It's all about how the atmosphere responds now. This is going to be a moderate to maybe strong event by the numbers, but that doesn't mean all that much at this juncture. PDO trend is encouraging. Lets see if the Aleutian low can get established, and in a favorable location. Pretty important in order for us to get the outcome we all want.
Not sure the lowlands see first flakes as the GFS op has been suggesting, but nice to see h5 looks like this in the near term. A month later this might be pretty interesting. As it stands, the western highlands may very well see some snow during these 2 periods.
Need some Fall HH beer talk up in here. Who is drinking what?
Really like the DFH PA Tuxedo with the spruce notes. Very much a Fall season Pale Ale.
Drinking a Utopias barrel aged 120 min IPA atm. Complex and totally delicious. Buzzing.
I agree. Been mostly bad luck for places along the fall line and just west lately wrt climo snowfall. The worm shall turn, and mostly likely it occurs in a Nino.
Interestingly, that area has done very well in recent Ninas. Jan of 17 and 18( I chased both), and again multiple times in Jan of 22. Two blizzards and 2 other storms of 10" plus. Maybe Ninos generally aren't cold enough anymore for the immediate coast, outside of a +PNA/-EPO pattern with cross polar flow.
One coastal storm with a somewhat offshore track and some cold in place-historically pretty common in a Nino- could dump a foot or more of snow right along the coast. That 0-6" call for that area busts with a single event. Ofc that is a DC focused 'forecast', so no one would really notice or care.
Boilerplate, generally a bit below climo across the entire region, although for DC itself that would be a good outcome. Very lazy effort. No attempt to capture subtleties/tendencies in Nino winter patterns.
