What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Synopsis
High pressure builds east across the area tonight. It'll be a
seasonably cool night under clear skies and light winds. On
Wednesday... Another cold front will drop south with a few
afternoon clouds and scattered showers confined to northern and
mountain sections. The front will exit to our south by Thursday
morning with even cooler and drier canadian air for later in
the week. The next disturbance approaches from the west for the
weekend with chances of rain and thunderstorms.

Near term until 6 am Wednesday morning
9:40 pm update...

a few changes to the forecast for the current weather
observations. Otherwise forecast is on track.

530 pm update...

minor changes to the forecast database to update temperatures,
dew points, and winds. Winds remain up due to the pressure
gradient and will be slow to drop until after sunset... Around
8:30 pm.

Previous discussion...

at 18z... A 1021 millibar high was centered over the upper great
lakes. Outside of a few fair weather clouds across the higher
terrain... GOES imagery showed clear skies across the forecast
area. The gusty westerly offshore flow in the wake of last
nights cold frontal passage had allowed areas outside the
mountains to warm into the 70s and even lower 80s this
afternoon. Areas near the international border were mainly in
the 60s. For tonight... The ridge will build east and southeast
into the region. Winds will diminish under the building ridge
and with clear skies and a fresh dry airmass in place... We'll
cool off rapidly tonight. Lows will range from the mid 40s to
lower 50s... With some upper 30s and lower 40s for the normally
cooler mountain valleys. Expect we'll see some patchy late night
valley fog as well.

Short term 6 am Wednesday morning through Wednesday night
On Wednesday... The ridge quickly slides offshore will a
southwest return flow developing. A shortwave impulse will push
a surface cold front southward from quebec by afternoon accompanied
by a band of clouds and scattered showers near the international
border area. Elsewhere... A mostly sunny day. Highs will range
from the upper 70s to lower 80s.

The cold front will press south across the remainder of the area
Wednesday night with a few clouds and widely scattered showers.

Lows will range from the mid 50s to lower 60s... But in the mid
40s to near 50 across our mountain zones.

Long term Thursday through Tuesday
Canadian high pressure will build southward into new england
Thursday and hold firm into early Saturday. Sunny and dry
weather is expected as a result. Friday night should be a chilly
one at the better radiators with lows possibly in the 30s well
north and west. Used a blend of MOS data for lows. Thereafter,
with high pressure moving offshore Saturday afternoon, we expect
a moistening return flow to develop. Low pressure will then
approach allowing for a chance of showers Saturday afternoon
with showers and thunderstorms for Sunday. Fair weather then
returns for Monday and Tuesday.

Aviation 02z Wednesday through Sunday
Short term through Wednesday night ...VFR. Isold MVFR psb btw
08 - 12z Wed in mtn valley fog. Sct MVFR psb btw 18z Wed and
04z Thu in mtn -shra.

Long term...VFR conditions expected Thursday into early
Saturday. Moistening conditions in tandem with an approaching
front may lead to lower clouds and showers Saturday evening
through Sunday.

Marine
Short term through Wednesday night ... Winds and seas continue
to diminish under building surface ridge. Southwest return flow
around the departing surface ridge and an advancing cold front
may briefly push winds and seas to near SCA late Wednesday
outside the bays.

Long term... SCA conditions will be possible over the weekend in
association with low pressure moving to the north of the waters.

Gyx watches warnings advisories
Me... None.

Nh... None.

Marine... None.

Near term... Hanes
short term... Schwibs
long term... Ekster
