large tornado by Mattoon IL

you can see the core of hail (up to 3") leans over the updraft near Decatur IL

possible tornado and 2.5" hail by Decatur IL

we've got to get some supercells quickly now in IL

I'm not even really sure how to process this potential day-4 threat (Wednesday.) The 500mb jet streak is much stronger than average, surface low pressure is lower than most pressure I've seen in June, other than hurricanes.

Now a total of 49 (unfiltered) or 44 (filtered) tornado reports are on the list for 6/11

I got sundogs right and left of the sun

My place got to 92 with a heat index of 101 today Yesterday: several showers and thunderstorms hit my place. It was the most rain since early May, I believe.

It's like an arrow of inky skies

This shows some of the 80mph+ wind reports and the extent of the squall line and some MPING damage reports

The NWS is already putting out a few considerable severe thunderstorm warnings in Iowa/Illinois for 70mph wind gusts

HRRR for tomorrow

non-confirmed tornado warning with now hail high into the sky, 60dbz going way up there

You guys already got 1" hail

Now the SPC has put out an outlook that wouldn't have been possible before this year: 15% double-hatched hail outlook for eastern Colorado. I would expect a severe thunderstorm watch in Denver. I'm sure last week's storm was a bit of a shock for lots of people... quick 15% outlook, and everybody gets hail all in one day.

Do any of you know how to access any new NCEP/NCAR reanalysis data? I was doing a daily map of 500mb anomalies, from the NOAA PSD web site : https://psl.noaa.gov/cgi-bin/data/composites/printpage.pl Then, in March, I found that the data had stopped. How has it possibly stopped? I don't get it. They do NCEP/NCAR reanalysis every day. But now they don't. Say for example, what if I wanted to do a plot of the global 850mb temperature anomaly on March 19, 2026? It's not there. The 20th-Century reanalysis project doesn't cover 2026. I emailed them. They gave me some brief answers, but not much.

How did you find the combined temperature average for Spring, and the ranking? I don't see any seasonal summary on the NWS local offices' climate web sites. All I can see is the climate summary for each month. Also, I can use the NOWDATA to see the average value or each (single) month. I am just curious.

This happened earlier. You can't even see the city names near Denver because the screen is covered with local storm report hail icons and MPING hail icons. Probably the new storm north of US-36 is the storm that chasers are heading to now.

The recent rainy pattern has reduced drought in the Southeast, eastern Texas, and Colorado.

This strange weather pattern has provided plenty of rain to Texas, with relatively little severe weather, and now rain showers are moving toward the Front Range cities from the SE

There were large sub-severe squall lines and a few supercells in Texas today. One supercell crossed the Rio Grande and produced a brief tornado at US-277 about 1 mile from the border
