LOT update. Subtle tip toes backwards:

SOME QUESTIONS REGARDING ANY IMPACTS OF UPSTREAM CONVECTION ON  
POLEWARD MOISTURE TRANSPORT THIS AFTERNOON AND EVENING WITH  
SEVERAL GOOD-SIZED HOLES NOTED IN THE PRECIPITATION SHIELD ACROSS  
NORTHERN MISSOURI. THAT SAID, UPRIGHT CONVECTIVE INSTABILITY IS  
PRESENT ON REGION SOUNDINGS (AND WE CAN SEE THE CONVECTIVE NATURE  
MANIFESTED IN THE RADAR RETURNS), AND HAVE ALSO SEEN SOME DEGREE  
OF THIS FILLING IN OVER THE LAST HOUR OF SO WITH THE ARRIVAL OF  
BETTER JET DYNAMICS. HRRR/RAP COMBO HAVE CERTAINLY TRENDED  
DOWNWARDS A BIT IN THE QPF OUTPUT AWAY
FROM THE LAKE, AND ENVISION  
THERE WILL BE SOME "HOLES" IN THE SNOWFALL TOTALS IN BETWEEN THE  
DOMINANT F-GEN FORCING AND AND ANY LAKE ENHANCEMENT. NO MEANINGFUL  
CHANGES TO THE SNOW TOTALS AT THIS TIME THOUGH, WITH OUR 4-7"  
INLAND
STILL LOOKING OKAY WITH HIGHER AMOUNTS NEAR THE LAKE. WE'LL  
SEE IF ANY DOWNWARD ADJUSTMENTS NEED TO BE MADE TO OUR NORTHERN  
TIER OF COUNTIES AWAY FROM THE LAKE WITH THE FULL PM UPDATE. 

Would agree with the northern counties "Boon, McHenry" with adjustment down

There's been several ob sites in southern/southeastern IA over the past hour or two with vis of 1/8, so it's really ripping to be sure in the heaviest snow.  We've been bouncing back and forth (obv estimating) between 1/4 and 1/2 mile type vis here.  Haven't measure anything but looks like a good inch down already.  

Looking upstream there's heavy snow falling as far west as extreme northeast KS, so still a long ways to go.

do you want to get flamed for making an optimistic post and using real ground truth to support it?

FWIW, the latest HRRR is too warm at places like DKB, ARR and DPA but is too cold at ORD and MDW.

DKB: 25 HRRR 27

ARR: 29 HRRR 31

DPA: 28 HRRR 32

ORD: 34 HRRR 31

MDW: 37 HRRR 33

 

More of a T/Td spread at ORD/MDW than the other sites, so some room to cool.  Also will help as CAA increases to help counteract the warmth coming off the 40+ degree lake.
