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.

Synopsis
A cold front will exit the region this evening, allowing showers
and thunderstorms across portions of maine to move offshore.

A warm front will approach the region Thursday before crossing
the region Thursday night. This will lead to very warm
conditions on Friday. A backdoor cold front drops into the
region this weekend and will likely provide for some unsettled
weather.

Near term until 6 am Thursday morning
Hrrr continues to have a very good handle on the ongoing
convection. The precipitation will slip off the coast over the
next hour or two and diminish. A northwest breeze will follow
drying conditions out across the region. There is still the
possibility of light patchy fog however in the penobscot river
valley where the heaviest precipitation fell today.

Cold air advection will continue overnight. This will allow for
readings to fall through the 40s with upper 30s likely in the
mountains.

Short term 6 am Thursday morning through Thursday night
On Thursday a warm front will approach the region from the west.

This will cross the region Thursday night with an increasing
gradient and strong warm air advection above the surface during
the overnight hours. The front will be relatively moisture
starved. This system will be the leading edge of much warmer
air to follow for late in the work week.

Long term Friday through Wednesday
A warm westerly flow will send temperatures soaring on Friday as
high pressure remains south of the region. Expect most of the
region to range through the 80s and will even approach 90 in far
southern new hampshire. A back door cold front will bring
increasing clouds and a chance of late day showers into far
northeast zones but the remainder of the forecast area will see
a dry day.

Cold front will sag south into northern zones Friday night and
will be the focus for continued shower activity in central and
northern sections of maine and new hampshire. Lows overnight
will range from the mid 50s north to the mid 60s south.

Cold front will continue to push south through the region on
Saturday and will end up stalled over southern new england by
late in the day. Looking for occasinal showers and perhaps an
afternoon thunderstorm in southern zones. Highs will range from
the upper 60s to mid 70s north and will range through the 80s in
the south.

High pressure building in from the northeast Saturday night
will set up an increasing onshore flow bringing ocean stratus
into southern new hampshire and southwest maine. Looking for
occasional showers with lows in the mid 40s to mid 50s.

Although the Sun angle is reaching its highest point
considerable high and mid level clouds may prevent this low
level moisture from burning off in inland locations on Sunday.

Occasional showers will again dampen the holiday weekend. Highs
will generally remain in the 50s across western maine and lower
to mid 60s in new hampshire.

Low level moisture will invade most of the forecast area Sunday
night and Monday along will a continuing chance of showers. Weak
shortwave moving in from the west on Monday will enhance shower
activity across the region. Highs on Monday will range from the
upper 50s to upper 60s. A weak cold front behind the departing
shortwave will push south into northern zones Monday night and
will continue south and offshore by early afternoon on Tuesday
bringing sunshine and warmer temps back into the region.

Aviation 19z Wednesday through Monday
Short term...VFR conditions expected tonight through Thursday
night. However, there will be some patchy inland valley fog over
eastern areas tonight with localized MVFR or ifr conditions
along and near the penobscot river valley.

Long term...

vfr Friday and Saturday. Areas of ifr lifr ceilings developing
in southern zones Saturday night and Sunday. Widespread ifr lifr
ceilings developing Sunday night and persisting through Monday
night.

Marine
Short term... Winds will be relatively light tonight and
Thursday. However, the gradient will increase with the passage
of a warm front Thursday night. Winds will likely exceed sca
thresholds at that time.

Long term...

sca's likely on Friday.

Fire weather
On Thursday, rh values will fall into the 20 to 25% range across
most of the area away from the coast. Occasionally gusty winds
will create an elevated fire danger.

Friday will see gusty west to northwesterly flow around 25 kt.

These winds will help to mix down dry air from aloft with rh
dropping to around 30 to 40% across southern new hampshire and
possibly portions of southwestern maine. This will put southern
nh near red flag criteria and will need to be watched for
possible fire wx headlines.

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.
