Version 3.4
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.

918 pm edt Mon may 21 2018

Synopsis
High pressure will slide offshore to the south of new england
this evening. A moisture starved cold front will drop south
from quebec and stall nearby tonight. This front will return
north as a warm front on Tuesday, spreading showers into the
area. Another cold front drops south through the region
Wednesday. Weak low pressure tracks along the international
border late Thursday into Friday. A frontal system tracks into
the area for the holiday weekend bringing widespread showers.

Near term until 6 am Tuesday morning
915 pm update: quiet evening with no issues. No estf changes
needed at this time.

605 pm update: skies generally clear across most of the region
with only some high clouds noted over northern areas. Minor adj
to temps based on latest obs otherwise no changes to forecast.

Previous discussion:
at 18z a 1025 millibar high was draped across the lower great
lakes. A weak cold front extended from the rooftop of maine
through the saint lawrence valley. GOES visible imagery showed a
band of broken mid cloud with the cold front otherwise skies
were clear across the forecast area. The weak boundary will drop
south across the area tonight and stall. GOES water vapor shows
an impulse over the northern plains. This impulse and an
associated surface low will race eastward with clouds arriving
from west to east across the area during the morning hours.

Short term 6 am Tuesday morning through Tuesday night
On Tuesday... The impulse and surface low will cross the region
and push the boundary northward as a warm front into southern
sections of the forecast area. A mostly cloudy day with showers
developing from west to east by afternoon. It'll be cooler than
today with highs in the 60s to around 70. Showers taper from
west to east Tuesday night as the impulse and surface low slide
offshore with patchy fog developing. QPF from this system will
average from 0.10 to 0.20 inches.

Long term Wednesday through Monday
There will be a gradual clearing on Wednesday. However an upper
level trough will linger to the west which may allow for some
destabilization and the threat of an afternoon or evening shower
or possibly a thunderstorm.

A ridge of high pressure over the region early Thursday will
give way to the approach of a warm front. H8 temperatures in the
+10c to +12c in southern canada will advect eastward. This will
allow for much milder conditions by Friday as maine and new
hampshire will be in the warm sector along with scattered
showers in the northern mountains. This front will become
relatively stationary over the region Saturday. Temperatures
will lower from the 80s to the 70s in most sections except for
southwest new hampshire. Expect more shower activity by Sunday
as the front settle south to the southern new england coastline.

12z model suite in relatively good agreement with the front
slipping south of our region.

Aviation 01z Tuesday through Saturday

diminish by early evening.VFR through tonight. Areas of MVFR
developing aft 16z tomorrow in shra. LCL ifr aft 03z Wed in fog.

showers and possibly a thunderstorm Wednesday afternoon and
evening. More showers with lowering ceilings Friday night into
Saturday.

Marine

through early evening as a weak boundary drops south across the
waters.

the proximity of a warm front Friday into Saturday.

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.
