Per NOWDATA, Ft. Collins monthly records are:
- March: 81˚
- April: 89˚
So, they could tie or break the *April* record just 2 days after St. Patrick's Day.
Unreal.
Quite the storm survey details from the Macon County, GA EF2 tornado early Thursday morning. 😲
The latest tornado counts we've tabulated from NWS damage surveys for both outbreaks so far this month.
March 9-12 tally may still tick higher with additional surveys.
Some parts of northern WI, northeast MN, U.P. have already picked up 6 to 12 inches of snow from last night and today.
Then, add the Sat-Mon storm to this. 😲
Welp, this would be the third severe weather outbreak in 10-11 days' time.
But this time, a different threat.
What you need to know👇
US weather checklist:
🌬️Today's winds
❄️ 🌬️ Sat-Mon blizzard, potential record 2-day snow for some in northeast WI, northern MI
🌩️ Rash of severe t-storms with high winds from Midwest, South -> East Sun-Mon
🥵 March record Southwest heat wave
🌧️ Hawaii storm (rain, wind, severe storms, summit snow)
Adjectives fail. Above Tuscon AZ, the strength of the predicted upper-level high (big red blob at left) is typical for late June.
In late May, it would be record-breaking early.
The European model ensemble suggests a high this strong (and hot) will arrive next week, around the first day of spring.
This photo shared with the NWS was from a record-smashing mid-April 2018 snowstorm in northeast Wisconsin's Oconto County.
Wonder if we'll see scenes like this on Monday after the upcoming (Sat-Mon) storm?

Hawaii checklist:
✅More flooding rain
✅High winds
✅At least a few severe t-storms possible
✅Big Island summit blizzard conditions
Kitchen sink...probably not. 😆
As pointed out first by @wxmanms1.bsky.social, the list of hottest March days on record in Phoenix...and our forecast next week.
Historic March heat wave for Desert Southwest ahead. 😲
A follow up...per the April 1961 Storm Data document, that 4/23/1961 Kankakee hail size (6 inches) was "unofficial".
So the standing state record appears to be 4.75 inch diameter hail in Minooka on June 10, 2015.
Per NWS-Romeoville, there were 6 separate reports of hail larger than that!
What are the odds of this coincidence?
The largest hail in NCEI's database dating to 1950 in Illinois is a 6-inch stone in...wait for it...Kankakee County on April 23, 1961.
A state climate extremes committee will examine this.
Sometimes, a higher risk severe weather forecast features one remarkable, long-lived supercell.
Tuesday, this supercell produced severe weather and multiple tornadoes for almost 4.5 hours over 121 miles from near Minonk, IL into Starke Co. IN.

Over the last 7 years, SPC has issued level 4 outlooks an average of 11 to 12 days a year.
First level 4 (of 5) SPC severe risk anywhere in the country in over 7 months, since July 28, 2025.
Threat for strong tornadoes in red shaded area by early evening.
Intensity level 2 now in just-updated SPC Day 1 severe outlook.
Potential for tornadoes of EF3+ this evening in parts of N. IL, N. IN, extreme southern Lower MI.
NWS has confirmed 24 tornadoes from last week's outbreak.
Unfortunately, a much larger fraction than usual were both strong (8 EF2 or EF3) and were killers (4 of them).
Recap 👇
I find reading NWS damage surveys fascinating.
In the Union Lake/City, MI EF3, an example that EF scale is a function of not only what it hits, but the quality of construction.
This may have been an even stronger tornado.

Quite a contrast in NOAA's Feb. (and DJF/winter) US summary:
Record warmest winter in nine states.
Cooler than average in eight others.
Among top 10 driest on record in 19 states.
Classic upper Midwest March forecast.
One day of record warmth (72˚ Monday), t-storms this evening, possible snow this weekend, then cold.
Wonder what negative rainfall means?
Just stronger evapotranspiration than average? 😆
On this date: the only known March hurricane (or tropical cyclone) on record in the Atlantic Basin.
And it wasn't a "fish storm", either.
Melissa joined quite a list of retired M storms, all since 1995:
Milton 2024 (tied strongest Gulf)
Michael 2018 (Cat. 5 Fla. Panhandle)
Maria 2017 (PR catastrophe)
Matthew 2016 (Haiti catastrophe)
Michelle 2001 (Cat 4 Cuba)
Mitch 1998 (C. America; 9,000+ killed)
Marilyn 1995 (PR, VI billion $)
The full list of Atlantic hurricane names retired since 1954.
One letter leads them all.
US severe convective storm (SCS) activity to ramp up. The Storm Prediction Center already flags 4 of the next 8 days with likely activity.
Outbreaks starting in March have accounted for a notable portion of annual SCS losses for insurers:
2020: 12%
2021: 12%
2022: 9%
2023: 20%
2024: 15%
2025: 26%
Classic "spring warmth tease" next week, followed by a reality check.
Parts of the Plains will have severe weather fatigue today - Tuesday. #rinserepeat
Where we are in SPC's new intensity forecasts for Day 3 (Friday). Mention of "strong tornadoes" (EF2+) possible in hatched CIG1 area.
And a shoutout to March 2022. which was the March tornado leader in the U.S. before last year's preliminary count.
