Fall 2020 weather discussion thread (warm, averages, Chicago, day)

Down to 38F officially in Indianapolis this morning. Coldest morning since May. We should drop that low again tonight. I'm seeing several colder reports, especially to the west, in the mid-30s. The coldest right now I see is Crawfordsville west-northwest of Indy reporting 33F.

I predict above average temperatures starting next week for much of the rest of October in the US. GFS looks like a blowtorch with chinook warming from the Southwest and Plains moving eastward, and the West Coast will finally start seeing cooler temperatures and more precipitation north of California.

It was the coolest so far on my old weather station for the Autumn Season, 40F, Floyd County, IN at 880 ft elevation, more than double the elevation of the area by the Ohio River.

It was just 36 F today morning. Coldest of the season so far.

Windy today. Overcast too, with a 20c high. Kinda what it should be right now, but the wind is just a weak echo of what's happening in France with the Alex storm.



Still pretty mild in the coming days.

Upslope winds associated with Alex have produced extraordinary rainfalls in the south of France.

268 mm is about 10 and a half inches. Not bad at all for 6 hours. Houston-esque one may say.

Time will tell: forecast skill for GFS is basically zero at hour 336. Yesterday it had a meridional pattern; today it's much more zonal.

Beautiful visible satellite imagery of Alex spinning up of the west coast of France. Click on the link to see the animation.

Strong winds too. Very impressed with how far in advance the Euro predicted this storm at what is not the usual time of year for such things.

For the second day in a row the sky here is hazy, it is the smoke from the wildfires in Ukraine.

Probably due to the haze, SE was also the coolest region in the country today. In Tallinn the maximum temperature reached around 20c, here it was 5c cooler.
