Area forecast discussion 
National Weather Service Gray ME
1054 PM EDT Wednesday Aug 20 2014

Synopsis...
two weak cold fronts will affect the region through the end of the
week. One moves in from the west and one from the northeast. Both
will produce little more then an isolated shower or
thunderstorm...and an increase in clouds. However...an onshore
flow will return the region to cooler weather through the end of
the week. A ridge of high pressure will anchor over Maine and New
Hampshire over the weekend and early next week...with a gradual
warming trend.

&&

Near term /through tonight/...
1045 PM update...minor adjustments to the latest forecast based on
latest trends in observational data.

730 PM update...have updated the
forecast based on latest trends in observational data. One main
change later tonight and tomorrow morning was to increase probability of precipitation for
showers and southwestern New Hampshire as models starting to come around to a wetter
/albeit minor/ scenario.

Previously... this evening will stay mostly clear...with light to
calm winds. Dew points are a little higher than last night...and this will
keep mins a few degrees higher than previous nights...and closer to
normal...generally in the 50s. Will see patchy valley fog once a
gain...but TI looks to be more prevalent...developing in some of the
valleys at the edge of the coastal plain.



&&

Short term /Thursday through Thursday night/...
500mb closed low the west begins to fill on Thursday...as another weak
low closes off the Gulf of ME. This will act to weaken and stall
the surface front approaching from the west...but will also pu;;
cooler air from the NE...which will set up another weak surface
boundary...enhanced by the onshore density flow. Look for clouds
to increase over northestern zones and in the CT valley region during the
day...perhaps bordering at M/cdy in both places during the
afternoon...with the threat of rain showers and maybe a thunderstorms and rain...especially
in the ME mtns/foothills. Coastal areas should remain part-mostly
sunny through the day. Highs will be limited to 70 to 75.

Thursday night will see some clearing as any clouds and rain showers will be at
least partially driven by diurnal heating. Some moisture pooling
between the two fronts will keep mins from dropping too much below
the middle to upper 50s.

&&

Long term /Friday through Wednesday/...
a frontal boundary will remain southwest of area through early
next week as a series of waves move along the front. This will
bring more clouds into the region for Thursday night and Friday.
A strengthening surface ridge over Maine will gradually push
frontal boundary southwest leading to partly cloudy skies over the
weekend and early next week with pleasant temperatures. A cold
front will approach the region middle week next week. New Hampshire
and the western mountains of Maine could see a shower late
Thursday night or Friday....otherwise dry weather is expected
across the region through early next week. Derived outlook period
from the superblend model.

&&

Aviation /19z Wednesday through Monday/...
short term...mainly VFR through Thursday night...except for valley fog at
khie/kleb...and perhaps a brief period around sunrise at
kcon/kaug.

Long term...VFR conditions expected except for morning fog in
favored areas.

&&

Marine...
short term...winds and seas to remain well below small craft
levels.

Long term...winds and seas expected to be below small craft
criteria.

&&

Equipment...gyx level 3 radar data not getting out as of 1030 PM...we
are looking into the issue. However...level 2 data are flowing.

&&

Gyx watches/warnings/advisories...
ME...none.
New Hampshire...none.
Marine...none.
