3/4 - 3/8 Multi-Day Wave Train

Only the 3rd time in KDSM Manual ASOS history (since 1996) that a confirmed tornado has been reported at the airport. I haven't checked the stats- but I believe this stretches a lot further back than 1996. For what ever reason.

The two loudest sounds known to man: a gun that goes bang when it is supposed to go click and a gun that goes click when it is supposed to go bang.

Heavy rain with thunder and lightning in Vadnais Heights, MN currently. And its 34°

James I’m a few miles west and south of you. I have some heavy pingers hitting the windows with lightning and thunder. I can’t believe how much of a bust the high temp was today. My weather station shows a high of 35.2. It was supposed to be 41. This could be a mess overnight.

The NAMs are showing 6+" across Iowa, but that seems overdone.  The 00z HRRR has only a couple inches.  The FV3 has 1".

season snowfall: 34.8"

'22-23: 30.2"      '21-22: 27.1"      '20-21: 52.5"      '19-20: 36.2"      '18-19: 50.2"      '17-18: 39.5"

Average snowfall: ~30"

I picked up a solid 0.51" of rain today from three storms.  Any thunderstorms in early March are a bonus.

Back from chasing in Iowa. Unfortunately didn’t see the big tornado due to being 15 miles behind and never catching up bc of the fast storm motions of 50-55 mph.

I was on a nice looking tornado warned storm but the main show came from the cell to my southeast.

Being behind and trying to catch up led me through the damage path of the storm.

First was the town of Orient, IA which was hit by 3-4” hail just to the north of the tornado path. Multiple cars had their windows busted out.

I made it to Winterset, and just south of town observed major damage.

After that, realizing I was never going to catch the storm with the 2 hour long tornado still on the ground south of Des Moines, I headed for home.

Quite the weather day experience for me. Went to bed last night with T storms  and mid 50s. Woke up to upper 30s and late am storms with pea sized hail. Left town and crossed into the warm sector with temps near 70. Came across 3-4” hail and tornado damage and beautiful sunlit supercells. Headed home crossing back into the cold sector and pulled up to my house with snowflakes falling!!

Boy, what a day of wx yesterday for the MW and the storms that barreled through IA.  The 1st line produced one strong cell that track right overhead with vivid lightning and loud thunder.  After that I went to sleep and was awakened by the second line of storms that went through N IL after 11:00pm.  Man, I gotta tell ya, the roaring sound of the winds out ahead of this line I haven't heard in a long time with the bare trees.  The sound it generates without the leaves on the trees is different when comparing it to a full tree of leaves.  It's hard to explain, but it certainly is "fitting" that MAR "roars" like a Lion, albeit delayed by a few days.  ORD had a peak wind gust of 66mph &  RFD 81mph...

Haven’t stepped outside yet but eyeballing it I’d say we got about 5” of snow overnight. So what was supposed to be mostly rain/mix turned into a snowblower event.

MPX: 

Overnight was a classic example of squeezing every ounce of energy out of the atmosphere over the Twin Cities as an intense mesoscale band of snow developed in response to a band of fgen centered in the h85-h7 layer. While most of you were sleeping, we saw snow rates of 2" per hour develop with this band, which quickly blanketed much of the metro in 3-5 inches of snow over the course of about 2-2.5 hours.

Models have generally raised our snow a bit this morning.  The latest GFS is its best run so far.

Almost every model showing 3-5” for Iowa City and Cedar Rapids now. 

I'm going in expecting 2-3".  If we get stuck under a nice band maybe 4" is possible.

Ended up with around one inch of rainfall from the rain and storms Friday night and Saturday morning. Very beneficial rain without having to deal with any severe weather around here.

Sendings thoughts and prayers for the 7 victims of the deadly tornado outbreak in Central Iowa yesterday… terrible news that this system took so many lives, including the lives of 2 young children.

Yeah I'm surprised. Looking out the window I'd say a few inches. I'll be heading out in a bit to clear the driveway.

Sheesh... the Euro has been leading the charge for a decent snow in Iowa tonight.  Now that all other models have finally caught on, the Euro dries up and is now the driest of any model.

We're seeing a dry band show up over far southeast and east-central Iowa.  I don't want this trending any farther north.

Looks like there is some fun weather going on in KC.TNklsHZG_normal.jpg

The (MCI) airfield is closed for all flights until further notice as a result of fast accumulating ice. Flight delays and cancellations are expected. Check http://FlyKCI.com
 
or your airline’s web site for flight status or rebooking.
