.DISCUSSION...
KEY MESSAGE 1...Fog likely tonight, especially Downeast. Fog
could be dense enough to impact travel especially near the
coast.

KEY MESSAGE 1 DESCRIPTION...
The marine layer this morning is expected to burn off by late
morning. However, some fog could move onshore along the coast
during the day today with the SSE winds. Although temps will be
cooler today, the southerly flow will continue to bring moisture
into the region. In addition, the next system will push more
moisture into the area ahead of the rain. These parameters will
prep the area for fog tonight as the winds calm and the temps
cool. Greater low level moisture will allow for the marine layer
to move into the coast again. Unsure how far north the marine
layer will reach, but the coast will see reduced visibility.

KEY MESSAGE 2...Rain Thursday into Thursday night, with higher
totals Downeast.

KEY MESSAGE 2 DESCRIPTION...
The closed low pressure system is expected to slow over New
England before tracking NE across the Gulf of Maine. The
ensembles and deterministic models show a better agreement with
the higher rain amounts staying in the south while the north
could see very little rain in the form of isolated showers.
Rainfall amounts seem to have decreased further, however, due to
the possible showery nature to the rain, still uncertain to the
amounts. There is some potential for a thunderstorm Thursday
afternoon, but not anticipating severe conditions.
