storm update, 19z sunday

well the models have continued to trend drier with QPF and the have placed the heaviest snow band further to the southeast. snowfall amounts will be a bit less then thought yesterday but will still be a significatn snowfall for the area with totals ranging from 5-9" locally 10" possible in some areas. the dynamics and moisture with this system will aid in some impressive snowfall rates at or above 1"/hr at times in the heaviest snow bands.

the heaviest snow will fall from late this evening through the overnight hours and shut off pretty quickly during the mid morning hours as the low pressure slides off to to the east.

LOT has upgraded parts of the area north of I-80 and west of dupage county to a winter storm warning starting at 9pm this evening and going through the day tomorrow.

It will be interesting to watch this system unfold tonight.
