602 am edt Sat aug 24 2019

Synopsis
High pressure will dominate the weather across the northeast
through Tuesday. Temperatures will be slightly below normal
through the period with a slight warm up by Tuesday. A slow
moving cold front will bring a period of wet weather for
late Wednesday into Thursday as low pressure moves well offshore
of new england.

Near term until 6 pm this evening
600 am... Minor estf update to reflect the current mesonet in
near term grids.

Prev disc...

at 06z... A 1027 millibar high was centered just north of the
great lakes. GOES imagery showed clear skies across the area at
moment. Light winds and mainly clear skies will allow some
patchy valley stratus and fog to develop across the forecast
area through dawn. For today... A mainly sunny start then a few
fair weather clouds with daytime heating and an upper trough
across the area. Highs today will range from near 70 along the
international border to mid and upper 70s elsewhere.

Short term 6 pm this evening through 6 pm Sunday
The upper trough will close off tonight... With the upper low
over the mid atlantic region initially then meandering to our
south through Sunday. With the exception of a few clouds... Little
in the way of sensible weather is expected from this system.

Meanwhile... The surface high center will be building by to our
north before exiting into the maritimes. The onshore flow around
the surface high could contribute to some late night fog or
stratus along the coast... Especially south of casco bay.

Otherwise... A partly cloudy night with some patchy valley
stratus and fog once again with lows in the mid 40s to lower
50s. It'll be a partly sunny and cool day on Sunday with the
onshore flow limiting high temperatures to the upper 60s and
lower 70s.

Long term Sunday night through Friday
Far weather is expected Sunday night through early Wednesday as
high pressure ridging holds firm across the forecast area. The
only rain in the forecast is late Wednesday into Thursday as a
short wave trough and attendant cold front approaches from the
west. There is a low probability that moisture from a potential
tropical system moving well offshore of new england could get
entrained into the frontal system producing a period of heavy
rain. However at this time it is most likely that the two
systems will remain separate.

Aviation 10z Saturday through Wednesday
Short term through Sunday ...VFR through the weekend except
for a few hours of lifr in fog and low stratus early this
morning and Sunday morning at kleb and khie.

Long term... Valley fog likely Sunday night through Tuesday night
withVFR conditions expected during the daytime. Conditions
could lower some late Wednesday as a cold front approaches, but
it will likely wait until Wednesday night.

Marine
Short term through Sunday ... We should stay below sca
thresholds. However... The extended period of onshore flow may
bring seas close to 5 ft for the outer waters south of casco bay by
late Sunday along with wind gusts to 20 kt.

Long term... Conditions are expected to remain below small craft
thresholds Sunday night through early next week. A few higher
swells may begin to arrive around Thursday.

Gyx watches warnings advisories
Me... None.

Nh... None.

Marine... None.

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.
