741 am edt Sun sep 24 2017

Synopsis
Above normal temperatures... As much as 20 degrees above
normal... Will be the rule across the north country today through
Monday. High pressure has become established over the area and
thus full sunshine and no precipitation is expected as well.

High pressure will begin to move east of the area Tuesday into
Wednesday... But above normal temperatures will continue. There
will also be a trend toward increased precipitation chances on
Wednesday and especially on Thursday when an upper level trough
of low pressure moves into the region.

Near term through Monday
As of 741 am edt Sunday... Overall forecast in good shape. Just
some minor tweaks to remaining low clouds and fog... But that
should go away by mid-morning. Otherwise... Best way to describe
the near term forecast period through Monday is record breaking.

High temperatures today and Monday will be in the mid 80s to
lower 90s which will establish new record highs both days... See
climate section below for specific numbers. Other than some
early morning fog this morning and Monday morning expect full
sunshine... Higher dew points... No precipitation... And light
winds as a large area of high pressure sits over the region.

With the higher dew points comes higher humidities and combined
with the above normal temperatures heat index values will reach
the lower 90s... Especially in the champlain and saint lawrence
valleys. As a result will go ahead and issue a special weather
statement related to potential impacts from heat index values
this high.

Short term Monday night through Tuesday night
As of 320 pm edt Saturday... The upper level ridge will remain
over the north country through Tuesday and as such the warm airmass
will remain in place through the middle of the week. 925mb temps
and MOS guidance all suggest temps on Tuesday will warm into the
low 90s so i've kept the idea of another day well above normal
as the forecast. This also pushes heat indexes into the 90-94
degree range.

While these temps are considered sub advisory(<95 f), they are
not to be taken lightly especially given the time of year. Based
on the forecast and current records, its expected that records
will fall at all sites by 3-5 degrees. Prolonged exposure
outside combined with strenuous activity can lead to heat
related injuries. Please take caution, stay hydrated and take
frequent breaks during any outdoor activities. This will be the
third consecutive day with 90+ degree heat indexes during the
afternoon. With upper 80's to low 90's temps, the overnight lows
wont fall that much. Expect lows each night in the upper 50s to
low 60s which is 15-20 degrees above normal for this time of
year.

Long term Wednesday through Saturday
As of 320 pm edt Saturday... The upper level ridge begins to
break down heading into Wednesday as a low pressure system
begins to finally track towards the north country from the great
lakes. With the flow aloft not turning zonal until mid day
Wednesday anticipate the frontal system moving through slower
than depicted by either the GFS or ecmwf. I've slowly increased
pop's for Wednesday night with the expectation that the best
chance of showers will be late Wednesday night just before
sunrise on Thursday. Pwat's aren't particularly high with the
system and so I anticipate generally some light showers across
the north country. There is a slight chance of some thunder
however the threat will only be over the saint lawrence based
on the idea that the front will be swinging through later and
thus the diurnal heating will be on the way down.

We finally get into some "normal air" Thursday into Friday
behind the cold front. Temps behind the front on Thursday will
still be in the upper 60s to around 70 however the cool air
advection gets going Friday and heading into weekend as 60s for
highs and 40s for lows can be expected by Friday.

Aviation 12z Sunday through Thursday
Through 12z Monday... Some lingering ifr to vlifr conditions at
kslk and kmpv due to low clouds and fog but this will be ending
around 14z and all areas will beVFR for most of the remaining
period. Look for a return of ifr to vlifr conditions at kslk and
kmpv after 06z due to low clouds and fog forming once again.

Winds will be less than 10 knots through the period.

Outlook...

Monday:VFR. Patchy fg.

Monday night:VFR. No sig wx.

Tuesday:VFR. No sig wx.

Tuesday night:VFR. No sig wx.

Wednesday:VFR. Chance shra.

Wednesday night:VFR. Chance shra.

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.
