.WHAT HAS CHANGED...
Confidence continues to increase for plowable snowfall across
southern NH on Wednesday night.

&&

.KEY MESSAGES...
1. A narrow axis of snowfall will develop from west to east
across New England Wednesday through Wednesday night. Light snowfall
accumulations will bring potential for slick travel Wednesday
evening and night across southern NH. Some north or south
shifts in the axis of snowfall remain possible.

2. The next chance of widespread precipitation looks to be in
the Friday/Saturday time period. While conditions look
supportive of mostly snow, there remains a wide spread of
solutions for snow magnitude and where it falls.

.DISCUSSION...

KEY MESSAGE 1 DESCRIPTION...
A frontal system will setup over southern New England on
Wednesday into Wednesday night as an area of low pressure
develops and moves along this boundary. To the north, high
pressure over Canada combined with northerly flow will result in
drier air over much of the region with a transition zone across
southern NH. As a result, a relatively narrow band of
accumulating snowfall is expected with the vast majority of the
snow accumulation to be confined to southern NH and towards the
Massachusetts state line. Latest 12Z forecast guidance shows
total QPF of generally between 0.10-0.20" across southern NH
with closer to 1/3rd of an inch towards the Monadnocks with the
assistance of some terrain enhancement. Forecast soundings show
a rather high DGZ (~600 hpa) with the greatest forcing for
ascent below this layer. In addition, there will likely be
around 20 kts of wind aloft, which will help to break up the
dendrites some. Therefore, snow-liquid Ratios (SLR) should be
generally
