1988 was weird, with a large drought, a scorching 104 degrees at Toledo in late June, then lows in the 40's for the end of the month of June. As for my area, it was +10.44F on the Monday-Friday period, some heat indices to 100 multiple times for the general area here is a heat index of 101 at KTDZ yesterday, before a brief thunderstorm outflow cooled the temperature to 85 (but it went back up) Oh, by the way, thankfully some significant rainfall to help the grass. The grass started to get brown when it was 99 or 100. But it got a bit better. Heavy rainfall happened in various amounts around Toledo on Wed/Thurs. Thursday's precipitation amounts indicate lake-breeze boundaries had a huge effect.

Midland to Saginaw may have seen some flash floods

This may have been a large tornado by Ainsworth Nebraska

This storm NE of Cheyenne had a tornado and 4.50" hail reported briefly, then 80mph wind in Nebraska

Flood in Detroit( 14 mile road underwater)

Toledo had 99 yesterday (broke a record), 93 today. It was 100 and 96 intra-hour high temps at Toledo's KTDZ. This airport seemingly has been running just a bit higher than TOL for a while. And it's always possible this isn't an equipment bias.

over 3.5" in Minnesota, South Dakota. Minneapolis Radar says over 5.50" southwest Minnesota. Not sure, but 7.0" might have been possible by Glencoe.

as for Toledo, there were multiple days of 90's last year (probably less than average) and the top for the year was 93, on only one day.

This was a measured hodograph with crazy storm-relative helicity. It was measured at the LNX radar after the low-level jet kicked in. There were some storms popping up in Nebraska, but no crazy isolated supercells.

With a little west wind, the air comes right in from the city to an on-land station at Summit St Marina. It's 86.4 in the Bay, as per a buoy

My place is scorching, with 101.3 on my home (indoor) thermometer placed outside in the shade. 58.9 dew point is suspiciously low. cooler by the lake (not really)!

interesting MCV

There is a severe watch for scattered thunderstorms. There is already one strengthening storm in Denver.

tornado warning that is by Cross Lake, or possibly well into the woods north of Brainerd MN

This so-called inflation-adjusted tornado count says that we have made it to 1000 tornadoes exactly after our active days of May

This is so nice. Maybe the temps are getting up to 50 there and melting snow fast?

There are dew points in the low 40s down to Columbus and Indianapolis today. The climatological average dew point value for June (whole monthly average) is 59 at/north of I-70, and 63 in Louisville

I've been kind of keeping track with it. You can probably say the Front Range is on drought-alert at some point Here's some cells that developed after the blob from earlier

There have been almost no storm reports in the Front Range cities this year, except for the hail you guys already discussed. That is going to change today, as slight/enhanced risk is in Colorado. Severe thunderstorm watch issued. Also notable, an area of dr&&&&t showed up on the US Dr&&&&t Monitor in Fort Collins, so obviously it has been too dry there. Otherwise, the D0 value unusual dryness is not too big.

did that rotation re-form northeast of Downtown?

Hi-res Baltimore radar

rotation continuing towards Lansdowne, near Baltimore
