Chilly morning at a few sties with 30's/lower 40's. Up in Cook county, temps down into the low-mid 30's.

DLH Spring ranking Max avg 48.5 (tied 30th warmest out of 83 unique avg's) Min avg 28.8 (tied 37th warmest out of 78 unique avg's) Mean avg 38.7 (tied 29th warmest out of 73 unique avg's) Precip 6.25" (58th driest out of 146 unique amounts) Pretty mid range, so an average Spring within the record, and somewhat on the drier side.

I use MRCC cli-MATE data portal. Josh may use something else. https://mrcc.purdue.edu/

As for this ASOS stuff, I personally have issue with them anyway. I made this known when I first joined the forum a few years ago. There main function is for airport ops, not climate monitoring. Their placements generally suck. I have found some smaller airports where they placed them in decent spots. One that comes to mind is Ann Arbor, and Eau Claire seems decent. So, in the end, I've just given myself this advice. "Suck it up, shut up, and just enjoy the f**king the weather!" And if homogeny is such a stickler for some, well, you might just as well abandon the temp profiles of stations, and get a job at a milk plant. So, again, take my advice I've given myself; "Suck it up, shut up, and just enjoy the f**king the weather!"

June 2 1945: Snow and sleet pile up to 4.5 inches at Tower. 1898: Heavy rain falls across Minnesota. Just over 7 inches is reported at Pine River Dam.

Thunderstorms in Illinois produced wind gusts to 70 mph at McComb and Mattoon.

Try finding something else here. https://psl.noaa.gov/data/getpage/ It's going to take time to redo stuff. I emailed them earlier this year, and they are understaffed, especially from retirements.

But there is a discrepancy in station data from moves. It all depends, like moving to/from large bodies of water, or inner city/town to more semi-rural/rural or vice versa, and significant elevation changes. Then you'll get diurnal changes, regardless of the equipment used. Then you have micro site changes that can affect that as well. Long term records are fraught with this stuff. It is what it is, and there has been lots of debate on adjustments that are made, or not made. Won't go any further with that.

This is what DTW Jan-May warmest mins look like. ASOS mins rather robust compared to pre aprt years by the looks of it. Man, some people's kids I tell ya! 1998 mint 37.5 1 1 1 0 2012 mint 36.7 2 2 2 0 2024 mint 36.4 3 3 3 0 1921 mint 35.8 4 4 4 0 2017 mint 35.6 5 5 5 0 2006 mint 35.1 6 6 6 0 1882 mint 34.9 7 7 7 0 1880 mint 34.5 8 8 8 0 2023 mint 34.4 9 9 9 0 2010 mint 34.4 9 9 10 0 1991 mint 34.4 9 9 11 0 1878 mint 34.1 12 10 12 0

This is a better summary for DLH starting with the beginning of the water year. Rollercoaster temps, and generally dry. Forgot about this section under the climate n past wx page.

Decent chance for rain coming later this week. Lets hope for a better month in that regard.

That reminds me, my grandfather started his in a grow room as well in the basement of their home. It was a room off to the side of the boiler room, so it stayed warm in there. Florescent lights hanging low over the flats. My grandparents were living in E Duluth (Lester Park) at that time (70's). They had a large lawn, so plenty of room to have a big garden. Mid 30's-40's across NE MN this morning. Near critical fire wx today with very low humidity inland. Makes for a larger spread in the diurnal range.

Here's the maps from May 28-29, 1947. CO low moved E along a boundary as HP from CAN pushed S into the Plains.
