-- Changed Discussion --545 PM Update: Just minor chgs to PoPs and Snfl amounts thru tngt.
Otherwise, fcst hrly temps and dwpts were adjusted thru the ovrngt
based on trends seen from late aftn obsvd temps. No sig chgs to
ovrngt low temps attm. Both synoptic and hi resolution meso models
cont to indicate meso-banding of snfl msly across NW to Cntrl ptns
of the region. Intially, mild sfc-925mb temps will keep sn to liq
equiv ratios low until later this eve when this column cools. Max
sn totals with best banding could lcly reach 3 inches ovr NW Cntrl
ptns of the region, with lesser amts elsewhere.
Orgnl Disc: The storm that brought significant snowfall to
portions of northern Maine yesterday will continue to move slowly
through the Canadian maritimes. As it does so, a trof will extend
westward across the region. At the same time, an upper level
disturbance will cross the region overnight. These systems will
bring a band of snow showers to portions of northern and downeast
Maine overnight. Any snow accumulation tonight will generally be
an inch or less, although some locally higher amounts will be
possible from the Katahdin region down through Houlton. Lows
tonight will generally range from the upper 20s north and the
lower 30s downeast.
Saturday will be a mainly cloudy day as low pressure continues
to move slowly east of the region and another weak upper
disturbance crosses the area. There will be a continued chance
for a few snow showers, mainly across northern and central areas.
Highs on Saturday will range from the lower 30s north and the mid
to upper 30s downeast.
