Mesoscale Discussion 0289
NWS Storm Prediction Center Norman OK

Areas affected...portions of central Vermont and New Hampshire into
central Maine

Concerning...Heavy snow=20

Valid 232310Z - 240415Z

SUMMARY...Heavy snow should continue across northern parts of New
England into the evening hours. 1-2 inch/hr snowfall rates and
periods of reduced visibility are possible, especially after 00Z (8
PM EDT).

DISCUSSION...Heavy snow is ongoing to the north of a strong
low-level cyclone that is currently traversing the Atlantic
Coastline. Regional dual-polarimetric radar data depicts the
transition line between all snow and mixed wintry precipitation to
be established from roughly the MA/VT border to central Penobscot
County, ME, and the latest high-resolution model guidance suggests
that this transition line should remain roughly stationary into the
evening hours. 700 mb frontogenesis is increasing along the
international border in tandem with increasing low-level WAA, and
this should encourage increased snowfall rates as moisture and lift
are boosted within the dendritic growth zone. 1-2 inch/hr snowfall
rates are possible, especially later this evening (i.e. the 00-05Z
time frame).
