.AVIATION...(For the 06Z TAFS through 06Z Sunday Night)
Issued at 138 AM EST Sun Feb 25 2018

Deepening low pressure across northern Wisconsin this morning has
allowed for strengthening pressure rise/fall couplet across the
Mid MS Rvr Valley. This strong couplet will race eastward across
the southern Great Lakes region through daybreak providing an
approximate 2 to 4 hour window of very strong post frontal west
gusts to around 40 knots. Gusty west winds will continue through
the day Sunday but should settle into the 25 to 30 knot range
after daybreak. IFR cigs will improve to MVFR with FROPA. Low
clouds should scatter later this morning with VFR conditions then
expected for the remainder of the forecast period. May also need
to watch for brief more significant vsby restrictions over next
hour or two at KFWA with mid level dry air advection allowing
precip to transition to more of a drizzly type, and with sfc warm
frontal zone in vicinity.
