.SYNOPSIS...
Prolonged dry conditions are expected with high pressure in place
through mid week characterized by pleasant afternoon temperatures
and morning fog for river valleys. Patchy frost this morning, and
potentially again late this week for Adirondack and northeastern
Vermont communities, will be the primary weather concerns. A dry
cold front will move through Thursday bringing northerly breezes and
possibly enhancing fire weather concerns given dry vegetation. The
next chances of widespread rain will hold off until late weekend
into the beginning of next week.

.NEAR TERM /THROUGH WEDNESDAY/...
As of 227 AM EDT Tuesday...Temperatures are cooling as expected
in the Adirondacks and northeastern Vermont supporting the high
likelihood of frost formation. Otherwise, high pressure will
persist with slowly modifying temperatures warming through
Wednesday. Frosty lows this morning in the 30s for the
Adirondacks/northeastern Vermont and 40s elsewhere will warm
into the low/mid 70s this afternoon. Tonight, temperatures cool
again, but lows will be favored to be marginally warmer(upper
30s and 40s). As such, frost chances will be more confined to
coldest hollows. Along Lake Champlain, temperatures should be
warmer, around 50 degrees, as a weak low level jet traverses the
Champlain Valley. Relatively warm lake temperatures will
support better mixing allowing for some breezes of 10 to 15 mph
to surface disrupting radiational cooling. Otherwise,
temperatures warm back into the 70s for Wednesday afternoon.
Morning fog will remain probable for river valleys.

.SHORT TERM /WEDNESDAY NIGHT THROUGH THURSDAY/...
As of 227 AM EDT Tuesday...Pervasive dry conditions persist Wednesday
night and Thursday as a dry cold front approaches and moves through
the region. While not a strong front, there is enough thermal
packing and sufficient pressure gradient to support daytime
gusts of 15 to 25 mph, with the Champlain Valley and higher
terrains on the higher end of this range. This will have
implications on fire weather since the region is experiencing a
period of significant drought. Fine vegetation will be parched
on top of dry 100/1000hr fuels - last week`s rainfall had little
impact on slaking moisture needs for larger fuels. These
conditions warrant continued scrutiny since they point to
potential for higher rates of fire spread.
&&
.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
As of 146 PM EDT Monday...The extended period of dry weather will
continue through the end of the week as high pressure remains the
dominant weather feature across the region. A weak and moisture
starved cold front will push southward across the region on
Thursday, bringing a wind shift and some increased cloud cover.
Winds will likely be breezy on Thursday as winds become northerly,
with gusts 15 to 20 mph for most locations and close to 25 mph in
the Champlain Valley. A reinforcing shot of cold and dry air will
push into the region behind this feature, bringing sharply colder
temperatures and additional chances for frost across the Adirondacks
and Northeast Kingdom with lows in the 30s and 40s elsewhere. High
temperatures will generally be in the 60s to near 70s for Friday,
warming a few degrees heading into the weekend. A few chances for
showers will be possible this weekend in an otherwise dry pattern,
but there is still plenty of uncertainty as to the evolution of this
feature.
&&
.AVIATION /06Z TUESDAY THROUGH SATURDAY/...
Through 06Z Wednesday...Dense valley fog has begun to develop
with otherwise clear skies. Coverage of fog is expected to be
largely limited to typical locations, impacting SLK and MPV and
perhaps briefly EFK. With light flow aloft, LIFR conditions that
develop should tend to be persistent rather than bounce around.
However, uncertainty in timing of onset led to caution on use
of prevailing groups. Satellite imagery does show fog is in the
vicinity of SLK and MPV already. It is more of a question of
when rather than if, likely after 07Z and especially after 09Z,
with improvement about 12Z to 13Z. Calm or terrain-driven light
winds will gradually increase slightly after 12Z out of the
south/southeast, remaining well under 10 knots.
Outlook...
Wednesday: VFR. Patchy BR.
Wednesday Night: VFR. NO SIG WX.
Thursday: VFR. NO SIG WX.
Thursday Night: VFR. NO SIG WX.
Friday: VFR. NO SIG WX.
Friday Night: VFR. NO SIG WX.
Saturday: VFR. NO SIG WX.
