IFR to LIFR conditions currently present across the Upper
Mississippi Valley this evening. Similar to the past few nights,
improvement is not expected in CIGs with visibilities likely
dropping (especially across Wisconsin) through the evening and
overnight hours with widespread dense fog already being
reported across NE Iowa and SE Minnesota. Fog will remain until
at least mid morning tomorrow before rain starts to move in
from the west along an approaching cold front. Rain will quickly
transition to snow with a few hours of wintry mix possible by
late morning and early afternoon. Snow will become the
predominant precipitation type through the afternoon with
blowing snow becoming more likely west of the river as winds
begin to pick up significantly. By tomorrow evening, winds will
be gusting out of the northwest between 30-40 kts across SE
Minnesota and NE Iowa (including the RST terminal). Gusts won't
start to pick up until late in the period for KLSE and east of
the river with winds peaking tomorrow night after 00Z.
