With all the rain we’ve been getting, the humidity in this heat wave is gonna be stifling. Yesterday the high on my pws was 90, but the HI was 104!

Interesting that both pac and atl have similar spatial patterns

Another 1” on top of 0.9” for a total of 1.9” this weekend. 2.5” MTD

Last night saved me from a total bust. 0.9”

Hoping I get another chance for significant rainfall today with the expanded flood watch

Only 0.05” imby

This wasn't about tropical cyclones...

No reason to think next winter will be much different than the last winter or the last several. Enso may not be a big player this year, so I’d lean more on the pdo and polar domain. Qbo going negative, but solar may have already maxed. No idea yet.

One of the things we’re working on with AI models is using hindcast climatology where the 10-15+ day cold bias is much less or no longer there. This might help solve the problem of models being too cold in their medium range forecasts. It’ll also be interesting to see if that also solves the bias of weaker upper level wind flow predictions vs reality.

If you’re talking about the biggest KU storms, I tend to agree. But there have been instances in recent winters where sub-KU storms have actually trended south in the last 24-72 hours. In the 2023-24 winter, my subforum (at least the central part) got 4-6” flush hits twice in the same week that trended to us the last minute after being modeled to go through PA/NY. This past winter, we’ve had a few happen the same way. Including one in late Feb that missed us and hit SE VA with a foot of snow, leaving us high and dry. So I guess it can cut both ways.

0.18” here this morning. May got me 8.77” for the month!

Got 1.6” this past event.

0.3” so far

Dry here. Just completely fringed. Glad this isn’t a snowstorm lol!

Don’t look now, but WCS daily PDO is no longer negative for the first time in many years

Haven’t been following the forecasts lately. I got 0.76” last night. Was that within forecast range?

C+/B- ended up with 17”, just a few inches short of climo but more days with snowcover during a cold january. Got lucky with the feb storm reaching warning criteria with a sharp cutoff just to the NW of me. Biggest storm of the season 7.5”

It’s interesting that athough the pac jet was stronger again this year, it was placed more equatorward compared to other recent winters since 2019. Makes sense as the south saw a lot of snow relative to their climo.

Heavy rain not much wind. 0.38" so far

I'll be in the WV mountains late march. Maybe a late season snow in the apps is in play...

Still shows a storm, but a miss to the south. Temps not great.

Latest CPC ENSO update backed off a double dip nina through SON. We’ll see if it continues to trend toward +ENSO or neutral.

Don't know why everyone is so downbeat. We're still awaiting cold to come the first week of march, and I was originally thinking the window of mar 4-10 we may have a shot, but with the -PNA being delayed by the euro ensembles, that window may be extended a bit longer. Maybe we're just burned out? That I can understand!

This is a great question. I think this is more true in the warm seasons as the poles warm much more relatively. But in the cold season, the poles are still cold even if anomalously warm, while extratropical latitudes stay summer-like warm (with all those 580-590+ dm ridges being more commonplace) - it's easy to imagine that the lat temp gradient gets even more compressed in the mid-latitudes. Granted it's not always the case everywhere, but I think it's becoming more common.

That does make a lot of sense when I think about it. And when we look at ocean warming in terms of absolute temperature instead of anomalies, it's easy to see how mid-latitude jets over both oceans would become anomalously strong as we've seen in recent years.
