Chinook

I got a video of a brief thunderstorm SE of Loveland and SW of Greeley. It was right at that time in the evening when you can easily see distant lightning bolts. I guess the lightning wanted to go down, then up.

picture from 6/15 (yesterday). Mammatus clouds from a fairly average thunderstorm

12 tornadoes today, widely scattered across the country. The tornado reported in Texas didn't look like it was from a mesocyclone. edit; another confirmed tornado in Indiana

It has been above 85 degrees once this year. Meanwhile on the West Coast,

Storms have blown up around Denver. There have been some hail reports near the north side of DIA. I'm sure there were a few delayed flights this afternoon.

That particular picture was from June 5th, when it rained in Fort Collins, but not much at my house. Last night (June 6) I saw a distant storm with bright lightning within the cloud at 10:00PM, to the south. The radar said it was near the north Denver Metro, so it was farther away than I thought.

Nice storm chaser pic of a lightning bolt near Fort Collins and Loveland

Another possible tornado in Ohio (SE of Mansfield)

Fort Collins was -5.9 F for the month with 2.92" of precip and 3.0" of snow. So, once again, very unusual to have so much of this year below normal. I think most days since February 1st have been below normal. My place got 2.12" of precip and 3.2" of snow. (Loveland Co-op observer had 2.69" for the month, so I may be a bit wrong on my calculation.) Mayjawintastawm, (as of 3:16) it looks like you have now had some storms at or near your place for 3 straight days Raindance-- did you get those hailstones in your yard?? Edit: 4:14PM - another heavy rain storm coming though Littleton

Oh, you mean like this St. Louis Cardinals game that got delayed?

Some 55-60 dBz severe-warned storms near Wyandotte, MI. I wonder if we will get a report from Michsnowfreak on this.

Another possible tornado about 20 mi from DIA (red dot, northwest of the radar)

One of the tornadoes in Colorado was about 1 mile south of FTG airport, that is, 1 mile or more from the radar tower. I wonder how close it got to doing damage to the radar or the hangar/terminals at FTG. Otherwise, it seems that other tornadoes in NE Colorado had no damage to structures.

Scattered severe storms could affect the Front Range and plains of Colorado and Wyoming tomorrow. 2000 - 3000 J/kg of CAPE should exist with daytime heating. Dew points will be 50 degrees and above.

My area had rain and snow recently. this is the latest I have ever seen snow. Previous record for me was May 18, 2017 (I think.) I only saw snow in May once in Ohio or Michigan. Loveland: 1.08" of precip, 2.4" of snow Fort Collins: 1.13" of precip, 2.0" of snow Look at how wet the US has been. Back in Ohio, I think they are having trouble planting the corn and other crops. The Sierra Nevada and Rockies just had a big snowstorm

Two (marginally) severe storms east of I-25 right now. CAPE is 1500 J/kg in northeast Colorado. I think something is happening on the Plains.

WPC 7-day QPF is high. The last 3 GFS runs have had over 2" in 7 days for me. This could be 20" of snow for the mountains. The GFS even shows lots of accumulating snow for Laramie at 7000 ft. First thunder of the year today!

Based on storm relative velocity, I think rotation was weak-moderate north of Leland (south of Shabbona) 11:44 AM.

Last week was mostly dreary and cold, considering that it's May. Monday: low 47, high 67, partly cloudy, cold front in the evening dropped the temperature to 49 for the evening hours. Some rain at nighttime in Fort Collins Tuesday: low 43, high 50, drizzle, fog, overcast Wednesday: low 36, high 48, breezy, overcast Thursday: low 33, high 41, some snow accumulated on rooftops/elevated surfaces in the morning. Later, some melting snowflakes (rain) and some graupel showers Friday: low 37, high 54. overcast in the morning, but partly cloudy for the afternoon and evening. CoCoRAHS preciptation Monday-Tuesday: Loveland: 0.05", Fort Collins: 0.50" Tuesday-Wednesday: Loveland: 0.04", Fort Collins: 0.03" Wednesday-Thursday: Loveland: 0.24", 0.8" of snow, similar in Fort Collins Thursday-Friday: Loveland 0.19", trace of snow, graupel/snow/rain, Fort Collins, 0.30"

This may have been the first 60 dBz and severe storm warning at I-25, this year.

Here is the new summer discussion thread. Today, we have had a cold front affect the area, and CAPE is developing. The CAPE may be up to 2000 J/kg near Denver in a couple of hours. Here is the first summertime SPC mesoscale discussion for our area: -- Probability of Watch Issuance...40 percent SUMMARY...Strong to at least isolated severe storm development appears increasingly likely through 3-4 PM MDT, with large hail the primary potential hazard. It is not yet clear that this will require a watch issuance, but trends will be monitored. --

There is a confirmed tornado near Lubbock. The radar images have looked even more impressive after the tornado was reported

Several storm reports today in KY/OH, including one tornado

March 1-16, 2019: 92 confirmed tornadoes (source, Wikipedia) March 2018: 55 confirmed tornadoes. We may be on pace to get over 120 confirmed tornadoes this month, as opposed to 55 in March last year. According to my calculations, the 2010-2018 average (not including hyper-active 2011) is 80.2 tornadoes.

Possible tornado at Toone, Tennessee, 60 mi east of Memphis
