KLOT aviation update
A lull in the IFR visibility reducing snow for many areas, except
in NW IN and near the lake, has occurred this morning in wake of
a leading band overnight into the morning hours. There is a more
organized band of snow associated with a secondary upper level jet
stream will lead to an uptick in snow at least for a couple of
hours this afternoon across the northern IL terminals. Expect
ceilings, which have increased to MVFR or even low end VFR to dip
back into MVFR or a lower MVFR then currently. Vis may drop back
to 3/4SM in this snow with medium-high confidence. Snow rates of
3/4" to 1" per hour may be possible in this band of dry snow.
