Quiet weather continues this memorial day weekend with today
shaping up to be the best day of the weekend with high
temperatures in the 70s and no precipitation. The next chance
for showers will come very late Sunday night into memorial day.

This will usher in a pattern change with potential for afternoon
showers almost every day this week.

Near term through Monday
As of 357 am edt Sunday... Patchy early morning fog should lift
rather quickly and after that, looking at a warm and dry day with
highs in the 70s, potentially pushing 80 in the valleys. Fair
weather cumulus will develop once again over the higher terrain
in the afternoon. Moisture should remain limited and no
precipitation is expected.

Sunday night will remain dry early before the mid-level ridge
pushes east after midnight. This will lead to mid upper level
low progressing eastward into the great lakes region. A surface
low and shortwave trough will pivot through the region,
dragging a warm frontal feature and associated deep moisture
through the pre-dawn hours Monday with widespread showers
developing through the morning. Hi-res models still hint at with
synoptic forcing associated with mid-level WAA as it lifts
north, there's potential a weak mid-level dry slot building in
briefly during the late morning to mid-day hours which could
bring brief period of reduced pops and the potential for some
gusty southeast winds along the northern slopes of the
adirondacks as well as western slopes of the green mountains as
a 925-850mb jet of 35-50 kts will be overhead. Thinking is
still the same as the previous shift, still not thinking this
will be wind advisory levels, but certainly gusts up to 40mph
are quite possible.

The chance for strong winds will quickly subside Monday
afternoon evening as a weak cold frontal boundary shifts
through area. With this we can expect to see another brief
round of showers and would not rule out a rumble or two of
thunder as well too.

Sunday night will see lows in the 50s, while Monday will see
highs Monday slightly below normal in the low 60s and low 70s in
the western counties..

Short term Monday night through Tuesday
As of 418 am edt Sunday... Once 850mb warm front lifts to our
north and east late Monday, should see relatively quiet and mild
conditions for Monday night. Deep-layer low pressure anchored
north of the great lakes will maintain s-sw winds during the
overnight hrs. Best chance for pbl decoupling will be east of
the spine of the green mountains, where lows will generally
range from 45-50f. Across the champlain and st. Lawrence
valleys, should see lows in the low-mid 50s for Monday night,
with s-sw winds 10-15 mph at times.

On Tuesday, will see some modest 700-500mb height falls from
west to east as center of upper low moves eastward across
northern ontario. Also, some indication of an embedded shortwave
trough moving newd from WRN ny into our region by late Tuesday
morning early afternoon. 850mb thermal ridge is slightly more
pronounced in advance of this trough in the 00z GFS as compared
to previous runs. Insolational heating may contribute to sbcape
values of 500-800 j kg per 00z NAM during Tuesday afternoon.

Dewpoints only in the lower 50s, but it appears ingredients are
sufficient for at least a slight chance of tstms heading into
Tuesday afternoon. Based on present timing, best sfc heating
should be across central s-central vt, and that should coincide
with best chances of thunderstorms aftn hours Tuesday. High
temps generally in the lower 70s for valley locations.

Long term Tuesday night through Saturday
As of 418 am edt Sunday... The long-term period will feature a
broad mid-upper tropospheric low centered in the mean across the
northern great lakes region into northern ontario. The north
country will be embedded within a belt of moderately strong,
cyclonically curved mid-upper level flow Tuesday night through
Thursday morning. While it is difficult to time individual vort
maxima within this flow, it appears their presence will be
frequent enough to result in periods of rain showers, especially
during peak afternoon heating on Wednesday. Some indication
that a shortwave ridge will briefly build across the region
Thursday afternoon, so will indicate lower pops for that period
(20-30%). A shortwave trough moving in from the canadian
prairies will reestablish the 500mb trough on Friday, resulting
in a better chance of showers with possible thunderstorms late
in the day Friday, with showers continuing into Friday
night early Saturday based on present indications. In terms of
temperatures, should see readings relatively close to seasonal
normals as we move into early june. Will see valley highs in the
low-mid 70s (except upper 60s Thursday), with lows ranging from
the mid 40s to lower 50s.

Aviation 08z Sunday through Thursday
Through 00z Monday... .Vfr conditions expected overall for most
locations. Clear skies and calm winds have led to radiation
cooling and patchy fog development in some locations and may
continue to do so. Currently vlifr conditions at kslk and will
continue through 13z. Kmpv may also see brief ifr mainly
between 07z- 11z. Kmss could also see some brief MVFR fog
development as well after 06z.

Conditions improve toVFR around 12z and persist throughout the
day. Winds will be out of the south on Sunday but remain
light... Around 10kts or less.

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.
