In case you are not aware yet the forecast from the last post was an epic bust… To quote Prof. Steve Nesbitt (UIUC):
Many have noted trends in precip and precip type with this storm – remarkable multi state shift through Chicagoland into central IL/IN. Very subtle changes in the upper level patterns, included a 500 hPa trough that weakened and dug slightly south and west than in earlier forecasts, making it more positively tilted. We’ll see what ultimately happens!
Out of a possible 12 inches in my neck of the we saw about 2.5. And the pavement was so warm I didn’t even need to clear…
My thoughts were captured by WBBM Reporter Bernie Tafoya:
cott Collis is an atmospheric scientist at Argonne National Laboratory and leads the Geo-spatial Computing, Innovations and Sensing Department.
He said Tuesday a lot of information was fed into weather simulations from Sunday’s 55-degree temperatures to the oncoming sub-freezing temperatures. The way the air was moving in the atmosphere made it a real “challenge” to forecasters, especially because the weather system was relatively small, only a couple of hundred miles wide.
Collis said the axis of unstable air actually moved farther to the south.

Well, sorry fat bikers, no snow.. Maybe it will dry out and we can get some gravel grinding in!
