the three times I had to go to PHX for work there was some weird weather phenomena...one flash flooding storm, actually made the salt river flow violent for a couple days, a heat wave in July 125+ during the day but the 95+ night wind was worse, and a crazy sand storm I saw coming from south mountain across sky harbor, don't like PHX but Tempe and Mesa were cool. Tempe especially because ASU campus is all around with a plethora of establishments to check out.

Heat Island effect - most areas away from the city will experience < 32 well before NYC

Stop trolling Its annoying

Torch !

If I’m remembering correctly, we had a super El Niño during the winter of 2015–2016. That November brought an unusually cold outbreak, with highs in the teens around midmonth, before a more typical El Niño pattern took hold for the rest of winter. With a recurving typhoon, Ural blocking, a weakening polar vortex, and other factors potentially lining up, I’m wondering whether we could see a similar November this year. Thoughts or rebuttals?

Max 64.1° What a beaut. Hopefully a few days like this every month until spring.

12z Euro looks great through early Novie

google it - its not made up AI Overview A polar vortex stretching event occurs when the large, circular ring of freezing stratospheric air above the North Pole loses its tight shape, elongating or warping into an oval or multi-lobed form. [1, 2]

Hopefully we get a nice late Fall threat, otherwise May isn't too terribly far off

Not to be weird but I wish you could enjoy it too!

I think it’s Indirectly a fallout from all the tropical systems off the Mexico coast this year. All that moisture swarming north. But I’ll take it!

Enhanced risk added with the D2 this afternoon for hail

I've never heard of Polar Vortex stretching before. This is a made up term!

Same up here and most of Maine where I've been this past week.

I think it’s a rare severe threat out there too.

Yeah the water restrictions will likely come back.

Beauty of a day here. Wife and I got almost the whole woodpile stacked but it got warm out there. No complaints!

Based on old recon finding lots of sub 900 storms in that basin and this having that very high end look it likely was below 890. .

Pressure data from a buoy on the edge of the eye sugguests sub-900mb pressure

The red oak sapling outside the window has a nice but not vibrant burgundy color but the 24"/90ft red oak 50 yards away is going toward brown. The only bright red oaks I see in this area are the pin oak street trees in Farmington - moderately common in the mid-Atlantic but not native to Maine. Jeff has a couple of them in his yard; haven't heard how they've colored this fall. Other than the oaks and some dark yellow understory beech, we're in stick season. Many of those beech leaves will turn tan and hang on until bud break in May. 22/25/27 lows the most recent 3 mornings.

JTWC had this at 155kt this morning, and so that's an incredible situtation, it's much above the 137kt cutoff for Category 5.

the center of the pac warm pool is east of the dateline!!! you would need this event to collapse to have any chance
