.LONG TERM...(Tuesday Night through Monday)
Issued at 238 PM EDT Mon Oct 24 2016

Active period taking shape with longwave trough and rapidly
deepening low set to track right across the center of the Great
Lakes. Leading edge of rain/showers with this feature will begin
to overspread NW areas Wednesday AM and then proceed east into
Weds evening. QPF amounts on the order of a third to one half inch
of rain appear to be in store as deep moisture will accompany the
system. Have kept slight chance of thunder in Weds afternoon and
evening given strong forcing and modest instability. Probably a
good thing instability is so limited as shear and helicity values
are rather high given triple point passing overhead. Next wave
will quickly arrive Friday into Saturday bringing yet another
chance for showers.

The active west to northwest flow will keep temperatures from
climbing much with highs generally remaining in the 50s.


.AVIATION...(For the 18Z TAFS through 18Z Tuesday Afternoon)
Issued at 122 PM EDT Mon Oct 24 2016

VFR conditions expected through the TAF period. VFR stratocu deck
mixing out steadily this afternoon, with a clearing trend expected

build southeast across the area, with clear skies and calm winds
expected overnight. Northerly surface winds will slowly veer to
easterly late in the TAF period.


LM...Small Craft Advisory until 8 PM EDT this evening for LMZ043-046.
