Chinook

Pellston MI, the Ice Box, was 29 degrees, yesterday. That's pretty bad for May. I guess it's known as being the ice box for being just far enough away from Lake Michigan to get away from the moderating effect of the water, and far enough north to be under the colder temperatures aloft.

this one would have annoyed me as the heavy rain just avoided Loveland. There was up to 1.25" hail in downtown/north metro at rush hour on the Friday before Memorial Day! Traffic got kind of slammed I'm sure.

1" hail reported at Englewood and Centennial

It looks like the forest fire smoke went away today. I hope it stays away. Probably not. I think it got pushed west, just to get pushed east later.

From what I can tell, the forest fire smoke has been above Colorado, as well as most of the Midwest. For my area, I noticed it a week ago, but I don't know if the smoke was over Colorado for all this time. Here are RMNP web cams haze other haze

I want some thunderstorms to track in the Midwest.

Global models have this storm going over Rota Island, Northern Mariana Islands, part of the USA.

Hello, Newman.

Excellent sunset photo

I need to turn on my thunder magnet.

Since there's basically nothing happening across the country, here's the skew-T for my area today, without the severe weather indices. The cooling of the cold front made the 925mb-850mb temp to 3 degrees C this morning. There wasn't an inversion in mid-day, but rather a strong heating from the surface to 850mb, with then a nearly zero lapse rate above that. That's quite a chunk of dry cooler air from 850mb-700mb. It was breezy. Yesterday, Toledo had 80/38, notably, lower dew points than NE Colorado yesterday. That's hard to do.

And, I might add, I still don't know why the HRRR has about zero smoke density in our area, when it should be a moderate value.

For me, the haze is obvious on the satellite image. I see a white-ish sky, but not a red sun tonight. There's only a been a hint of the slight yellow tint of the sunlight that happens when you get heavy forest fire smoke.

I mentioned this in the Mountain West discussion: British Columbia had temperatures on 5/14 and 5/15 I don't think I've seen in May at any time.

This has got to be forest fire smoke. It's a red sun tonight. The HRRR says the vertically integrated smoke is zero, but that's wrong.

Somebody is getting a heat wave. The Great White North

Today: down to a temperature of 63 with a dew point of 39 here. I sometimes forget that the more dry air, like I was used to feeling out in Fort Collins, does exist as we get closer and closer to summer. The 500mb pattern is a complete mess

Some info from the NWS at Boulder

CoCoRAHS spotters measured as low as 1.05 to and as high as 3.65" within a couple of miles in the San Antonio vicinity

I guess this continues the sort-of trend of wet Mays, going back several years. I probably just remember this trend because most of the months in my recent personal memories of Colorado haven't been rainy at all.

This is massive debris

Tornadoes in Nebraska

The only time Fort Collins got close to 5" was the flood of 2013. Fort Collins had 5" in a week, Horsetooth Mountain had about 9".

That's crazy
