This is crazy. I didn't see anything about this until someone in the NE Ohio thread mentioned. 

 

There have been a few of these massive downpours over Lake Erie during the summer months over the last several summers. It happens when the lake water is in the upper 70s/lower 80s and we get slow moving convection over the lake (usually at night). Put-In-Bay got 8-10” of rain and flooded one night in August 2023, and there have been a couple other times where I remember radar estimates of 10”+ over the open lake. This event was very high end and affected an island directly. There was significant flooding from 4-7” of rain (after 1-3” the day before) along the western Lake Erie shoreline on Monday from continued lake enhanced thunderstorms.

Couple days of ne winds with lil bite keeping us in the upper 70s before heat builds back

Had been wondering, lake are big enough that hypothetically if they get warm enough, you might see some pseudo tropical processes briefly at play

Nice night to have the windows open and cool the house down.  Low of 48 here, cool spot in MQT County was 40 @ Eagle Mine.  Warm day in the upper-70's on tap before another round of heat settles in.

It will be interesting to see which model wins the heat battle this time, last heatwave it was the Euro lower on temps. This time the Euro is going nuts and the GFS is subdued.

Yeah, there definitely was some positive feedback over Lake Erie that night with the convection helping to develop a mesolow, which in turn then kept the convection relatively stationary and intense.

Locked in on summer classic

For all you Minnesotans out there, the International Falls evening weather sounding said 89/71 with 4447 J/kg of CAPE with no storms nearby.

Thinking higher temps this heat bubble in my backyard versus the round of swamp azz from two weeks ago.

Gonna spend a lot of time floating in the lake after work this week

Rare severe storm over the Keweenaw coming in from the nw has held severe intensity since Isle Royal.  Usually the cold water is a death nail to storms.  Hopefully it holds together as it approaches the n shore of Marquette County.  A storm would be nice to kick off the heatwave.
