Synopsis
Deep low pressure over central quebec this morning will continue
to provide abundant cloud cover to the north country today,
along with areas of fog and drizzle this morning, and some
scattered rain and snow showers across north-central vermont
this afternoon. A brief period of sunnier and drier conditions
is expected on Thursday as a ridge of high pressure builds over
the region, but unsettled weather returns for the end of the
week and into the weekend, as another storm system will bring
valley rain and mountain snow Friday into Saturday.

Near term /through Thursday/
As of 718 am edt Wednesday... Deep low pressure over central
quebec this morning continues to provide abundant low level
moisture to the north country in the form of areas of cold
drizzle and fog with current temps ranging through the 30s. Cold
air advection continues through the day on northerly flow, and
while precipitation chances generally wane across the majority
of the region, additional shortwave energy rounding the base of
the upper trough will skim along the international border
maintaining the threat for scattered valley rain and mountain
showers across central and northern portions of vermont through
the afternoon. Abundant cloud cover will persist through the day
as well, keeping temps in the mid 30s to low 40s in the valleys
while the higher summits gradually fall through the 20s.

For tonight, the upper trough finally begins to swing east of
the area with surface high pressure and and upper ridging over
the great lakes and ohio valley edging ever so slowly eastward
towards the region. Low levels finally begin to dry out with
subsidence aloft winning out, so a gradually clearing of skies
is expected though mainly after midnight with valley locales
clearing the most, mountain areas less so. Lows will range
mainly in the 20s with some teens in the adirondacks.

Thursday will be the best day of the week as the aforementioned
high centers over the northeast with skies continuing to clear
through the day. Unfortunately temps won't really change to much
as weak cold air advection will continue on light northerly
flow, but we should realize widespread highs in the low/mid 40s.

Short term /Thursday night through Saturday/
As of 341 am edt Wednesday... Most active period of weather then
affects the region by late Thursday night and especially Friday
into Friday night as upper closed energy tracks east from the
ohio valley into the mid atlantic region. The forecast remains
quite complex in regard to precipitation timing, amounts and
type with lower boundary layer thermal profiles playing a
critical role through the period. This is not uncommon with
early spring systems with subtle changes of 1 to 2 degrees
either way potentially leading to large differences in sensible
weather. For now will maintain our prior idea of snows arriving
into our southwestern counties later Thursday night into mid
morning on Friday before a transition to all rain in lower
elevations, or rain/snow mix from 1000-2500 feet on Friday as
precipitation shield advances into the remainder of the forecast
area. At higher elevations above 2500 feet p-type may remain as
all snow. Negligible amounts of sleet or freezing rain is
expected. Lows Thursday night mainly in the 20s with afternoon
highs on Friday from 35 to 40 below 1500 feet and 30 to 35 above
that level.

Bulk of precipitation then affects the area Friday night as warm
thermal advection aloft will be peaking and as thermal profiles cool
slightly a transition to all snow is expected after midnight.

Amounts may be a bit tricky as flow trends southeasterly and some
slight shadowing effects may occur. Time will tell. I was also
cautious in leaning too high on our QPF given known model high bias
during warm thermal advective events. Nonetheless the potential will
exist for a light to moderate wet snow accumulation in many areas
with higher amounts possible in elevated southern terrain. Did lean
on the milder side of guidance given clouds and lack of appreciable
low level advection - mainly lower to mid 30s (upper 20s at
elevation). Please see our winter weather page at

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
