Hurricane Michael IR satellite loop that I made http://www.greatlakes.salsite.com/Hurricane_Michael_IR_loop.html

My area is getting the storm now. The temperature has fallen to 30 quickly. We have some snow accumulation of 1/2" or less, with 20-30mph wind gusts (gust to 36mph at Fort Collins-Loveland Airport)

Here is a silver maple tree in Colorado. We had one like this in Ohio. Not too many maples are in the cities in Colorado. The hardwoods of the East are uncommon for the dry western climates.

Silver maple leaves on a bright, sunny day! There have been so few moments with blue skies and sun since the leaves turned.

With the snow and the cold coming up here, the trees might drop their leaves before you can appreciate them.

This is looking better as far as getting precipitation in this state. The western areas have done pretty well. Fort Collins and Loveland have gotten 0.6" or better. I got 0.65" at my place this month, including that snow that melted on contact. The snow happened for a number of hours on Wednesday, but didn't accumulate. Coming up this weekend - accumulating snow!! I think it's a little too early for this.

That's hilarious. Thanks.

The only map you will ever see with 919mb on the United States mainland

We are getting our first snowfall. Right now there are decent size clumps of flakes. At the same time as a kick-butt hurricane landfall. I hope everybody is OK in Florida.

For what it's worth - the significant tornado parameter is up to 1.0 over the Kansas City region, and is expected to reach 1.0-2.0 values over Missouri/Iowa in 2 hrs (SPC mesoanalysis)

14-day precip analysis shows that some heavy rains and floods have happened over the central US. Kansas City may be breaking out of its drought. Localized floods happened in the southwest with Hurricane Rosa's remnants. I would think that SW Oklahoma and vicinity, Kansas City, and northeast Iowa into Wisconsin may have had floods within the past several days. Drought reductions are mainly centered on Texas, Oklahoma, and Missouri, and Arizona.

There's another couple of hurricanes headed for our country and some of the Plains got heavy rain last night. The East just keeps getting wetter, the West just keeps getting drier.

Can't we just have rain, like any normal place? Columbus Day (Tomorrow): Rain and snow showers likely before 11am, then rain showers likely between 11am and 4pm, then rain and snow showers likely after 4pm. Some thunder is also possible. Areas of fog. Otherwise, cloudy, with a high near 41.

The models are showing that Hurricane Sergio will make landfall on the Mexican coast, and the moisture will continue onward to New Mexico. This particular GFS run is probably over-doing the pressure in New Mexico. There should be a trough somewhere in the northwest or northern Rockies at this time, but details are uncertain. This particular 1-week forecast makes it seem like maybe some sort of super-snowstorm will converge upon Colorado, but it won't. But the thing to really take away from this is that some more drought-busting rain is likely in New Mexico.

Keep up the hope. My last 0.25" in Loveland was Aug 18-19. overall 0.14" in Loveland in September, and about 0.53" in Fort Collins in September. Today, we had some rain for maybe 1/2 hour, and one rumble of thunder. Western areas should get 1.0" to 2.0". Front Range areas should get 0.5" to 1.0"

Now taking a look at the SPC 17z outlook, maybe areas north of Madison may be the areas of interest (in contrast to what I said before)

The models are showing a line of showers and thunderstorms popping up around Madison WI tomorrow at 03z. The severe parameters aren't too bad. If the area can maintain over 1000 J/kg of CAPE after sunset, then maybe we will get some severe reports in Wisconsin or Illinois. It might even get close to Chicago.

I hope that works out alright. The NWS WPC plots show 1.0" to about 2.0" for foothill locations near the cities of Utah, in the short term. As for Colorado, we should have a chance for rain on Wednesday, Friday, Saturday, Sunday, and Monday. The models show snow in Wyoming, Montana, and western North Dakota on Monday. (ECMWF is relatively close to the GFS on this 7-day forecast)

Typhoon Trami, as viewed from the International Space Station (I think.) See twitter for animated image (very cool). Typhoon Trami effectively made landfall on Okinawa, Japan, and there are a lot of U.S. Military members there.

Interesting question. Now that Hurricane Rosa is forecast to be in Arizona as a post-tropical low on Day 5, the confidence for heavy rain in Arizona is getting much higher. I wonder if Yuma to Las Vegas (Colorado Valley) will get more rain from this storm than they got over the entire July-August time period (main monsoon season.... maybe?) That also might happen with part of the Arizona high mountains. It seems that the GFS and Euro show some rainfall getting into Utah and southwestern Colorado. How much more beneficial rain might happen in UT, CO, and NM with the former hurricane or perhaps a second mid-latitude low pressure in the 5-7 day time period?

There have been few days that have featured interesting or unusual weather recently. Probably the most unusual thing in the past 2 months was the heavy smoke of Aug 20-25th, if I remember correctly. Otherwise, we had a streak of above normal temperatures in the area from about September 8th-24th, depending on reporting station. Rain has not been too much to talk about for my area. Today, a cold front finally made it cold. The clouds were very low today, and the temperature was about 48 degrees before noon, and we had drizzle and lower 40's in the afternoon. I wasn't expecting the drizzle. Yesterday's NAM model did in fact say it would be 43 degrees at 3:00PM and it was right. We had the coolest mid-day temperatures since April.

Does this look familiar? David Dahl of Colorado homers for the 4th consecutive game, to help the Rockies win

Rockies got a bit closer to making the playoffs by beating up on the Phillies. Denver doesn't have playoff chances in -most- Septembers.

Phoenix hurricane??

By my estimation, a possible tornadic circulation traveled from Rockwood, MI to northeast of Amherstburg, Ontario. Gibraltar, MI is in between those.
