Fun to see the words back in discussions.. here's a question...

Is snow more common on Mt Washington, NH or 6200' in Idaho in September? Maybe same? But wouldnt happen at same time though.


Pretty sure my one friend who is an observer up in mt washington recorded some snow the other day. Not sure how much but he posts videos all the time from what is going on so cool to see.

Early year for colors but 85-90% still green. We started about 2-3 weeks earlier than usual this year. Cool pattern since Aug 24th. But now with the pattern flipping it should slow the progress down.

Otherwise we would be peaking incredibly early.

Posted in winter as well

think this was necessary. There will be less headline titles

I noticed it looks like Eurasia is getting ready to go in the Deep Freeze. This happened last year.... certainly didn't help for winter in the US


This trough in the west had to come around sooner or later, this winter might be of those in which the western states get their snow early and then mid-December the pattern flips. I know I'm not giving any reasons for that but will later on. This weak La Nina I think will make the pattern in the west rather progressive in the winter months.

Trace of snow reported Aug 31-Sep 2 on Mt. Washington, and a trace on the ground as well. I am no longer in the area so I didn't get to see if the white was visible from my old house 15 min away. That would be early, even for there.

Was looking at 1st measurable snows for up there and they seem late this year. Usually by mid September they get some.(sept 10 is the avg). Latest was Oct 19th, 1960.

With the trough out west and ridge in east next week sounds like they might have to wait till end of Sept this yr?

What a tale of 2 halves this month. Sep 1-15 was very cool in east, warm in west. Pattern is going to completely flip for the 2nd half. July-like temps are expected later this week.

Maine, bucking the trend. cool.gif been summer like up here. Prefect too, because most vacationers are gone. It's like two different worlds once you cross labor day. Actually the camps close down a couple weeks prior.

Good thick foggy morning to you folks! Already seeing plenty of leaves changing and falling. Getting close to "leafer" season when every motorcycle within 100 miles drives over the mountain and are very often followed by ambulances. (seriously)

Am quite excited to see how this fall progresses as we did not have a 90F day this summer. Summers when we cant squeak out a 90F day or two are many times followed by a quick decent into cold and snow. This 7-10 warm up is wonderful, and am now quite interested to see what follows.

Aside from a couple tenths on the 1st, September has been extremely dry. We've been on the edge of D0 status throughout the summer, but right before it would get worse we'd luck out and have a good thunderstorm or two. That pattern has died out completely with no end in sight (at least for the next week). Trees are starting to change, but that's as much to do with the dry weather than the cooler temps, I'd imagine.

And now we're going to be 10 or so above average for the next week, to boot. Ugh.

It feels warmer than yesterday, but we are likely to miss the 80s yet again. It stalled at 79 degrees yesterday and the day before. Our opportunities for 80s are dwindling. In the sluggish weather pattern that we have been in this year, we seem to need a minimum of 60 or higher to get a max of 80 or higher. Our low this morning was 59. In Elmira, Ithaca, and Syracuse, it should reach the mid-80s. Even when you factor in elevation, we should be able to make it to the 80 s, but the temperature always seems to hit a brick wall at 78 or 79.

There are signs of the east cooling down over the last couple of days of the month into early October once Jose and Maria move away from the U.S.
