Late week rain system still on track to affect the Northland — Here’s what the 12z models from Tuesday are showing for potential rainfall amounts from Thursday through Saturday morning.
Goes-16 visible satellite loop from Tuesday, July 17, 2018 (Loop time, ~11 AM to ~5:45 PM) A scattering of fair weather cumulus clouds over the Northland today with one exception, locations close to Lake Superior saw fewer cumulus clouds today thanks to the light lake breeze and more stable air.
Note: Quiet tornado season continues across the U.S. with 571 tornadoes reported through June 27 — 2005 through 2015 average through June 27 is 1004, so we’ve seen ~57% of the average number of tornadoes through late June.

Climate Data for July 17, 2018
International Falls, Minnesota
2nd coldest low temperature on record for July 17 with a low Tuesday morning of 43 degrees. Record low is 42 degrees set on July 17, 1918.
4th coldest low temperature on record for July 17 with a low Tuesday morning of 45 degrees. Record low is 40 degrees set on July 17, 2017, and on July 17, 1971.
Pleasant summer weather continued today with mostly sunny to partly sunny skies. Highs were in the low to mid 70s, slightly cooler near Lake Superior.
An area of high pressure was over the upper Midwest this afternoon, this high will move over the central/eastern Great Lakes Wednesday with a milder southerly flow developing on the backside of that high — This will lead to high temps in our area on Wednesday reaching into the mid 70s to low 80s. As for tonight, patchy clouds early on otherwise mostly clear with lows in the 40s and 50s, could be some patchy fog especially in river valleys.
Our nice weather as of late will be going away by Thursday as rain overspreads the Northland from SW-NE. Rain reaches southern portions of the area Thursday morning, and areas farther north/east by Thursday afternoon the way it looks now (Note: Timing could change a bit over the next 24 hours)
Occasional rain and showers will likely continue Friday as a surface and upper level area of low pressure tracks slowly toward the east/southeast across the upper Midwest.
Highs Thursday and Friday are forecast to be in the 60s and 70s with a few 80s possible Thursday in northern Minnesota.
Could be dealing with some more showers from time to time on Saturday, possibly even on Sunday if this low pressure system doesn’t move far enough away from our area by late this weekend.
Note: It’s a big weekend for dirt track racing around the Northland. Superior on Friday, Ashland Saturday and Proctor Sunday — Unfortunately the weather doesn’t look too good, story of the summer I guess, at least for these bigger shows this season. Will see if this rain event late this week will trend more to the south, that’s our only hope right now, but so far the computer models have been locked in on a not so good weather forecast around here, especially on Friday, things might improve just enough to get the shows in this weekend in Ashland and at Proctor.
Forecast for Duluth and Superior
.Tonight… Mostly clear. Low 50 to 55. Wind east at 5 to 10 mph.
