Chinook

People are now talking about how Google Deep-mind ensembles beat the other ones on Hurricane Isaias.

Maple tree from a couple of days ago we'll see way more bright colors, I think, with low temps getting lower, but not freezing

category 5

Crazy day for temperature

tornado reports from a few days ago

After a rainy/drizzly day yesterday, the clouds cleared off at nighttime, and Toledo dropped to 36. The high temperture 54 today was a real shocker. Obviously, it's not that uncommon for a temperature of 54 to be in early October, but we avoided the cold temperatures so far, with the warm weather pattern. My general idea is that the really good colors of fall start to occur after a few days/nights when the temperature is cold, but not (much) below freezing. Colors of the trees can get really uncolorful with a hard freeze. I saw that in Colorado twice in 16 years.

The high temperature of 87 at Martinsburg, West Virginia broke the daily record. It had a high 87, a low of 59, and an average temperature of 73, which was 18 degrees above average. The high was only 82 at Washington-Dulles, which is not that far away.

CoCoRAHS shows 0.6" to 0.7" total for Fort Collins-Loveland, 0.9" Broomfield, over 1" Boulder, 0.55" Denver, 1.5" Golden (past 4 days)

Same at my place. The dew point was way up! The dew point is 65 right now, giving us high relative humidity once again at night time.

90 is insane for Minneapolis!
