OgimaaBines	06/17/2025 08:33AM   I was watching this one last night as it hovered over the whole BWCA with some pretty high radar returns . Hopefully all the trippers/ troopers stayed safe and dry out there. Screen-grab around 9:30pm last night (CT)
LindenTree	06/18/2025 05:06PM   Guessing this is the Rain guage used at the Ely airport, its called a tipping bucket. It tips over for every 100th of an inch of rain. Pretty hard for it to leak but I'm sure it can malfunction. I managed the RAWS/Remote Area Weather Station at Detroit Lakes USFWS for years and never had any problem with any of the components, Just changed out the battery and other components every couple of years. Rain Guage Tipping Bucket
WhiteWolf	06/18/2025 05:15PM   Anything automated is likely going to be a tipping bucket as mentioned by linden. They are quite accurate in light/moderate rainfall but really lose accuracy in heavy rain compared to manual rain gauges because in the "tipping" procedure they lose precip by it spilling out-- usually 10 to 15% lower than a manual gauge in heavy rain. pinetree- correct -- the ones used by most Coop Obervers are 4" or 8" in diameter -- 8" being "official" but a little bulky/ heavy and costly for 1000's of coop observers.
Soledad	06/18/2025 11:00AM   There were lots of folks on Ely's FB page showing 3" of rain on Fall, Farm, 4 on Garden- over 4 on Vermillion. Two reports of 5" on the north shore of Shagawa. The BWCA got more than the airport... or the airport has a leak ;)
LindenTree	06/17/2025 08:39AM   Good deal, just wish it was more wide spread. Only .05 inches in Ely and .12 in Duluth.
NEIowapaddler	06/17/2025 12:05PM   LindenTree: "Good deal, just wish it was more wide spread. Only .05 inches in Ely and .12 in Duluth." If someone reported .05" in Ely they should check their rain gauge for leaks. Both the radar and actual rainfall reports had 2-3"+ for the Ely area.
Pinetree	06/17/2025 10:11AM   LindenTree: "Good deal, just wish it was more wide spread. Only .05 inches in Ely and .12 in Duluth." Looks like -to me Ely got over 3 inches or close to it-? These rains this summer have such discreet lines where it has been falling. My favorite checker-observers-just zoom in rain gauges

White Wolf is my Iowa weather guy. It was WDIO Duluth. Ely airport reported .11 inches. .11 inches at airport.
WhiteWolf	06/18/2025 05:50PM   How a 8" is measured. Local one here at KDSM airport.
Pinetree	06/18/2025 04:26PM   Whitewolf-it is minor difference for us home owners. But I can have two different rain gauges and one will usually be 10% more. It is a rectangular one with like a 1 x 1.5 opening the other is a half circle. I know most official ones have a big round opening.

" Yeh also sometimes I think to hard,I imagine the rainfall hitting the edges of the container and maybe square ones for the same opening surface area size sq. inches opening get less or more because of surface or inner glass side area varies. Especially in a windy situation. My explanation probably confusing. I remember in 2012 we had one month like 30 inches of rain-maybe a state record. But often it seems the airport one totals fell behind many local rain gauges. We had numerous 4-5 inch rains. We had floods everywhere. I have no idea what they had for a gauge. I know the local forestry office had the round opening one, but they dumped it manually back than.
