a spectacular flip in temperatures from yesterday`s highs in the
70s to today near freezing temperatures today and lake effect
snow showers across the area with a strong upper level low
pushing through the great lakes region. temperatures will be
colder yet tonight with lows by tuesday morning sinking into the
teens. with still breezy to gusty northwesterly winds will see
wind chills down to near zero degrees early tuesday. with the
gusty winds and lake effect snows with around 3 to 5 inches with
a few locally higher amounts for areas near and surrounding
lake michigan a winter weather advisory will continue through
tuesday morning to address that fact. most areas outside of the
advisory will see accumulations up to 2 inches by tuesday
morning.
a weak disturbance will ripple through the northwesterly flow
behind this deep trough that will move into the northeast. this
disturbance will bring some nuisance light snow showers across
the area tuesday night into wednesday morning. less than an inch
expected with that disturbance and most areas seeing around just a
trace.
strong/broad ridging over the southwest conus/northern mexico
will begin to push northeastward and will allow for synoptic
warming across the region with the ridge axis pushing well north
into central canada. a warming trend from wednesday into the
weekend with high temperatures by thursday back into the 50s
with a few rain showers possible and then warmer yet on friday
and saturday with generally dry conditions and highs getting
into the 60s. slightly cooler on sunday with another disturbance
pushing into the northern great lakes.

a large trough full of embedded vorticity pushes through the area
between this evening and tuesday allowing for the ongoing lake
effect snow. off and on snow showers has caused reductions in
visibility across both terminals today and would expect that to
actually become fewer and further between for fwa tonight. as the
daytime instability pushes away this evening, a multibanded setup of
lake effect snow will still be able to cause times of mvfr cigs as
well as times of mvfr and ifr visby at sbn. also expect gusts to
slowly relax this evening from the 30s of kts to the 20s of kts.
expect snow to dissipate during the morning hours tuesday
allowing a return to vfr conditions everywhere.
