Models show a low-amplitude shortwave trough moving over the top
of an upper ridge centered over the eastern U.S. and Quebec, with
a weak surface low moving east along a slow-moving boundary
centered across the Northeast.  Cold air to the north of the low

indicating accumulating snows likely from the northern extent of
the White Mountains into the Central Highlands and North Woods
regions of northern Maine.

Rain changing to snow associated with a shortwave trough lifting
across Minnesota is expected to produce some light snow
accumulations Wednesday night into Thursday morning across
portions of the Arrowhead region.
