Labor Day Heavy Rainfall in Ohio. Summer heat to snow out west

 Stalled front between 6am and mid afternoon created training of storms across most of northern Ohio.

Radar loop from 5am to 7pm Labor Day





More than 90% of northern Ohio received 1" or more (green or yellow colors) above



I calculated that more than 80 BILLION of gallons of rain fell over a 12 county area between 6am and 6pm. 

Labor Day's rainfall ranks 3rd all-time at Hopkins? 



Here is the top 30 rainiest days. I boxed in red the events that occurred in September.


Today's rain is exactly 24 years after the remains of Hurricane Fran passed over eastern Ohio setting our single day rainfall record of 4.59"


I dug up some of the NWS Cleveland forecast messages from the Iows Mesonet Database (check it out. It's a great resource) issued from that day in 1996:

Message from 8:30am 9/7/1996
8:30am message from NWS Cleveland on 9/7/1996

10:40am NWS message from NWS Cleveland on 9/7/1996


All of this here in Ohio doesn't compare to the dramatic changes parts of Colorado will go through weatherwise over the next 24 hours. Mid 90s to ower 30s with accumulating snow!



Per "Maxar_Weather" on Twitter: "...Years in which Denver recorded both a 100° high and measurable snow. The shortest time in between was 25 days in 1962, with 100°+ on 8/14 and snow measured on 9/8. Denver reached 101° on Saturday and is expected to record measurable snow three days later--Tuesday."
