good call
KLOT update
Another area to watch is around the I-88 corridor west of and
into the Chicago metro where a stacked 850-700 hPa F-gen axis is
generating a narrow but moderate to heavy precip band aloft. Some
12Z CAMs latched onto this band, but the dry air feed from the
north will erode this band to some extent near the ground. Will
continue to monitor this axis for the potential for a quick couple
inches of snow.
