Mesoscale Discussion 0064
NWS Storm Prediction Center Norman OK
1010 AM CST Tue Jan 17 2017

Areas affected...From central New York into parts of the North
Country

Concerning...Freezing rain

Valid 171610Z - 172215Z

SUMMARY...Areas of mainly light freezing rain are expected to
develop across central and northern New York today.

DISCUSSION...Latest surface analysis at 16Z shows sub-freezing
temperatures from central into northern NY, with several areas
colder than forecast by RAP or NAM point forecast soundings. This is
resulting in ongoing freezing rain along a Syracuse Johnson City
line currently.

Aloft, an area of warm advection will persist ahead of a weak
shortwave trough, with the 850 mb freezing line well to the
northeast of the discussion area. Therefore, precipitation should
remain liquid with either rain or freezing rain, depending on the
surface temperature. Despite some diurnal warming, a saturating
column should result in cooling, with a few pockets of sub-freezing
temperatures remaining especially in higher elevations.
