Severe Weather 8/10 - 8/13

Looking like a miss se imby, can't win em all and glad to spread the wealth

The models' overnight forecast was awful.  There is no big MCS rolling through sw MN and far northern IA.  Instead, it's just an area of scattered meh convection farther south in Iowa.

i'd be really cautious buying into the big talk regarding tomorrow, until morning that is.

there's a subtle wave in the sioux falls region this evening, which will translate east overnight. it appears that we should see t'storm development ahead of this feature, along the diffuse boundary across iowa and n illinois tonight. if this activity becomes too significant or lingers too deep into the morning, the big mega derecho hype will fail hard.

best in the game imo

Quite a bust locally these last few days

Had a nice hail storm this morning. Up 1/2” IMBY but many areas reported 1”.

boundary near you, if IA complex gets its shit together, you're in a good spot imo

6 warnings in Iowa right now including a tornado warning, and still no watch out lol.

Swing and a miss north with this wave for this area.  Again.

Thought I'd be waking up to some high-end garden variety stuff, but a pretty potent bow approaching I-70 now. Watch just issued that mentions scattered 80mph gusts, didn't think we'd get that until the afternoon

Heck of a complex this morning. I go to my office at 7 am, I can’t remember ever having back to back days with a severe thunderstorm warning when leaving the house

development has occurred. we'll see how it trends the remainder of the night and into the morning.

the bigger issue may end up being upstream, actually. most guidance is doing a fairly bad job regarding the evolution of things across the dakotas and vicinity. most guidance suggested that mcs formation would come from supercells tracking across the dakotas this evening and tonight, paired with additional development as well. not only should that scenario already have been unfolding by now, but it seems to be out the window based on evolution in reality over the past few hours.

if this big mcs is going to come to fruition, it'll have to be from an entirely different process than most guidance had shown.

big guidance fail.

instead we had a cluster develop south of sioux falls.

now we have an mcs, which has struggled to mature and organize as it has crossed iowa all morning.

it is at the bare minimum raining in droughtville USA

What a mess of modeling today.

Cluster kinda fell apart as it got down towards me, but still some decent gusts. gusted to 39kts at Lunken and CVG which more than verifies the 40mph SPS. Surprised that wilmington dropped the SVR, though I haven't seen anything that would verify 50kt winds. 

Hopefully PM round is more electric

[homedis]

Looking at the radar loop, this thing really sped up in the last hour or so. Let's see how fast it dives SE.

s tier training in n indiana, probably for the best that didn't end up right over the metro area

[homedis]

Some nasty wind gusts approaching Rockford area and south (75mph-85mph).

[nvck]

Gust to 82mph at Columbus' John Glenn airport !! SVR-D now.

Ready to rock and roll.

Heavier east of here but it’s basically been storming for the past 6 hours.
