729 am edt Sat may 27 2017

Memorial day weekend looks to start out great with dry weather
and fair conditions expected for Saturday and Sunday along with
a warming trend.The back end of the weekend will see showers
will return to the area late Sunday night into memorial day. A
pattern change will see slightly cooler temperatures and a
chance for showers almost each day this week.

Near term through Sunday
As of 725 am edt Saturday... Just some minor temperature
adjustments for the morning update. Forecast overall seems to be
on track.

Previous discussion... High pressure builds into the region for
most of the memorial day weekend. This will lead to a warming
and drying trend for today into Sunday. Lingering clouds will
remain around through mid-afternoon today before more
discernible clearing happens overnight into Sunday morning. The
dry and warmer weather continues on Sunday as the high pressure
ridge crests over the area bringing another day of fair
conditions. High temperatures for Saturday will be in the upper
60s to low 70s while overnight lows will be in the mid 40s to
low 50s. With Sunday's decreased cloud cover and weak southerly
flow, high temperatures mid to upper 70s with some valley
locations possibly touching 80.

Short term Sunday night through Monday
As of 328 pm edt Friday... Will see another pattern change
beginning Sunday night as 700mb shortwave ridge translates ewd into
the gulf of maine and broad closed mid-tropospheric low shifts
slowly ewd across the great lakes region and ontario. Onset of
mid-level height falls and developing cyclonic flow aloft occurs
during Sunday night, though the 00z ECMWF is about 6 hrs slower
than 00z GFS with arrival of shortwave trough vorticity max
embedded in swly flow moving into the north country. Have gone
with more consistent GFS timing for now, which means likely pops
(70%) for showers into NRN ny during the pre-dawn hrs Monday,
with chance pops (30-50%) across vt. It appears that best
synoptic QG forcing will occur during Monday morning, with
widespread shower activity associated with strongest 850mb waa.

Overall QPF generally 0.25" - 0.50". Should see partial clearing
occurring later in the day Monday as 850mb warm front shifts
north and east of the region. Can't rule out a few additional
late day showers with weak surface based instability possible.

Have included slight chance of thunderstorms late in the
afternoon for the st. Lawrence valley area and s-central vt. 00z
gfs SBCAPE values reach 600 j kg at kmss at 21z mon. In terms
of temperatures, the increasing clouds will keep overnight lows
mild Sunday night, generally in the low-mid 50s (except upper
50s in the st. Lawrence valley). There is an increase in s-sw
gradient flow, reaching 10-20 mph after midnight in the
champlain and st. Lawrence valleys. This will also help with
low-level mixing, keeping temperatures from dropping
significantly. A lake wind advisory may ultimately be needed for
lake champlain later Sunday night into Monday morning
associated with this increase in southerly gradient winds. With
only partial clearing expected later Monday, high temperatures
will range from the low-mid 60s across central ERN vt, the upr
60s in the champlain valley, and mid 60s (adirondacks) to lower
70s (st. Lawrence valley) across northern ny.

Long term Monday night through Friday
As of 328 pm edt Friday... Large mid-upper level low pressure
system will be our controlling weather feature through much of
the long-term period. This vertically stacked system will
drift slowly ewd from the NRN great lakes ontario Monday night,
ewd into WRN quebec by Thursday. Northern ny and new england
will be embedded in associated cyclonic flow, with several
shortwave troughs crossing the region from wsw-ene Tuesday
through Friday. It appears the best chance for shower activity
will generally be during afternoon periods, with combination of
relatively steep mid-level lapse rates and surface heating
resulting in shallow instability and shower development. Have
indicated likely pops Tuesday afternoon, followed by 30-50%
chances for Wed Thu Fri afternoon. Temperatures will generally
reach the low-mid 70s on Tuesday, followed by upr 60s to lower
70s Wednesday, and mid-upr 60s on Thursday as thermal trough
aloft gradually shifts ewd into our region. Min temperatures
will range from the upr 40s to mid 50s... Close to seasonal
averages for late may.

Aviation 12z Saturday through Wednesday
Through 06z Sunday... .Most stations areVFR with the exceptions
being kslk and krut which are lifr and ifr respectively. Both
should improve toVFR by 14z at which point all stations should
stayVFR for the remainder of the period.

Wind will be northwesterly at 5-10 knots during the day before
going light and variable overnight.


Sunday:VFR. No sig wx.

Sunday night:VFR. Chance shra.

Memorial day: MVFR. Breezy. Likely shra... Tsra.

Monday night:VFR. Chance shra.

Tuesday:VFR. Breezy. Chance shra.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
