Synopsis
Warm, humid weather continues today and Wednesday, though it
will be cooler for areas closer to the coast. A cold front will
move into the area Wednesday night, bringing an end to this warm
and humid air mass, replacing it with a cooler and drier one.

This cooler, drier weather will last through the weekend.

Near term until 6 pm this evening
900 am update...

quick update to drop dense fog advisories. Vsby in most areas on
the way up and any remaining fog will burn off over the next
hour. Aside from a few temp TD tweaks... No other changes planned
attm.

Prev disc...

715 am update... Plenty of fog will remain early this morning
and dense fog advisories have been modified per current
observations. Visibilities are down to a quarter mile in many
areas.

If leb or con were to reach 90 degrees today, they would have an
official heat wave with three consecutive days in a row with
readings at or above 90. With fog this morning and high clouds
crossing the region today, have forecasted slightly cooler
readings than yesterday. Nevertheless, most areas will top out
between 80 and 90 degrees today with the warmest readings once
again in southwest new hampshire. Coolest readings will be along
the coast, particularly the midcoast region where ocean
temperatures are the coolest with the onshore breeze.

Otherwise, a large ridge of high pressure will continue to
dominate the region today.

Short term 6 pm this evening through 6 pm Wednesday
Plenty of fog redevelops tonight through early Wednesday
morning. By Wednesday afternoon, the long awaited cold front
will be approaching the region. There will be a chance of a late
day shower over northern areas. CAPE values increase and there
may be sufficient instability for thunderstorms as well. One or
two of these storms could produce gusty winds.

There may be a shower along the midcoast as well as moisture
converges along a prefrontal trough. Readings will continue to
be above normal with temperatures still between 75 and 85
degrees for afternoon highs. This will be due to an increased
southerly flow off the gulf of maine, so the warmest readings
once again will be over southern and western new hampshire away
from the marine layer.

Long term Wednesday night through Monday
Cold front crosses the area Wednesday night with a chance of
showers or a thunderstorm as it does so. The best forcing for
precipitation will be sliding to the northeast, so precipitation
in our area will not be very widespread, with the northwest
portion of the area most likely to see any rainfall. This front
will be an air mass changer, with a cool, dry air mass moving in
behind it and lasting through the weekend. An upper trough
slides by on Saturday, possibly triggering a few showers, but
mainly just serving to reinforce the cooler air. High pressure
builds out of the great lakes and into the northeast Sunday and
Monday, bringing light winds and good nighttime cooling
conditions.

Aviation 13z Tuesday through Saturday
Short term... Areas of lifr conditions early this morning in fog,
improving today. Areas if ifr and lifr conditions redeveloping
tonight with this very humid airmass.

Long term... There could be areas of ifr especially along the
coast Wednesday night ahead of the cold front. The front should
clear this out, though, withVFR conditions expected through the
weekend outside of valley fog at night.

Marine
Short term... Have placed areas of dense fog in the marine layer
for much of the day. Visibilities will frequently be near a
quarter mile in fog.

Long period swells have arrived along the midcoast region from
maria. Periods on 4 to 6 foot swells are up to as long as 6
seconds. Have issued scas for seas for the eastern outer waters
based on this trend.

Long term... Long period swell may reach 5 to 6 ft through
Thursday. A cold front Thursday morning will shift winds to the
north, though wind speeds are expected to remain just below 25
kt.

Tides coastal flooding
High surf advisories have been issued for much of the midcoast
region except for coastal waldo county which is protected by
islands in penobscot bay. The swells are being produced by
maria. Expect long period 4-6 foot waves to reach the shoreline
today, mainly northeast of portland. There will be a high risk
for strong rip currents in this areas.

Gyx watches warnings advisories
Me... High surf advisory until 6 pm edt this evening for mez025>027.

Nh... None.

Marine... Small craft advisory for hazardous seas until 6 pm edt
Wednesday for anz150-152-154.
