Chinook

Yes, that area got baseball size hail yesterday. Pretty bad stuff, considering we are out of the peak severe weather season. Greeley has had 1.52" of rain since September 5th That's 10x the amount of rain I got in August, 0.15".

Large tornado reported near Guernsey, Wyoming. This is kind of late in the year for this.

Some rain showers with some areas of heavy rain.

heavy rain/hail hit south and west Denver, Estes Park. My place had enough rain to have wet pavement.

Severe thunderstorm warning in the Denver area foothills.

Fort Collins had a high of 97 yesterday, breaking a record of 95 set in 1899. (Weird, usually the cold records from from 1899). Surprisingly, it got cloudy and rained for a bit, and then it was about 91 degrees with mostly cloudy after the rain! Fort Collins has had 18 days of above normal temperatures since 8/15.

I was out of town yesterday, in Ohio. Thankfully, I missed being here for this record heat. Today, I landed in Denver with cloud bases of 4000-5000 ft and temps of only 80 degrees. I was wondering why the clouds were so low.

Sunset over the mountains. Note: the calculated sunset time is 7:37pm, but I took the picture at 7:22pm, a difference of 15 minutes due to the fact that the mountains are at about a 1 or 2 degree angle above the flat horizon.

Maybe Oklahoma City is getting a very wet August? By the way, 87mph wind report near Piedmont, OK. I have heard that there was a probable tornado near Edmond.

Denver was 97 today (record high is 99). Fort Collins had a record high of 96 (record was 95). The sunset is getting earlier these days, but it was still 89 degrees at sunset.

Radar shows that about 1" fell at about the Denver city limits, up to 3.12" south of downtown, on I-25

Flash flood warning issued for Denver.

Denver has had highs of 99 on Monday and 98 today. 99 set a record high for 8/19. Fort Collins set record highs of 96 and then 98. Today, my area got to 96-99, and then we got a cold front, concurrent with a thunderstorm outflow boundary traveling westward from Weld County. The temperature dropped to 80 and stayed near 80 for most of the evening. We have had a lack of significant rain for many days.

On 8/11 (Sunday) apparently there was a 4.83" hailstone at Otis, Colorado, which is a new state record. NWS Goodland mentioned it on their web page, and twitter feed.

Some areas of Kansas and Nebraska have gotten 3-6" of rain in one week. My place has gotten about 0.20" of rain in an entire month.

I think I saw some of that last night. I went outside at about 10:30 and there were thunderstorms just east of Fort Collins and just south of Loveland. I could definitely see the whole cloud lighting up with lightning near Loveland.

This is a fine picture

Tomorrow, the EHI and tornado parameters could be nearly the maximum that you might ever expect in the month August. Thunderstorms are likely across central Illinois.

Some tornadoes and hail up to 4" in diameter have hit northeast Colorado. This radar image is north of Wray, CO.

Some development of severe storms is possible near Denver today. SPC has an enhanced risk of severe storms out near Goodland. The storm near Castle Rock looks like it will get a severe storm warning in the next hour.

Japan's radar web site shows that the eyewall has tracked over Tarama Island recently. This is close to Ishigaki. https://www.jma.go.jp/en/radnowc/

GFS has two storms in the next few days in the Pacific. Typhoon Lekima, farther west, is expected to be 130 kt (Category 4) near Ishigakijima, Japan and also at 80 kt near the Chinese landfall point (JTWC)

Today, moisture values and CAPE values are higher than normal, with a few storms right now east of I-25, with some light rain at Boulder and Denver right now. Maybe there could be more storms this evening. For July, this area was 1-2 degrees F above normal. (1.3 degrees F above normal at Fort Collins.) The rainfall was alright but below normal. My best estimation is that Loveland got 1.05" and Fort Collins got 1.27". So finally, after our cool and cloudy springtime and the cool and cloudy month of June, the prairie grasses are getting tan.

Radar-estimated rainfall for that day. yellow =1" red = 2", magenta = 3". There are a couple of pixels of magenta on the north side of US-36, east of Estes Park.
