.DISCUSSION...
KEY MESSAGE 1...
Low relative humidity expected today and Thursday which may
lead to increased fire weather concerns in areas with no snow
pack.
KEY MESSAGE 1 DESCRIPTION...
High pressure ridged south of Maine will bring dry conditions
and low relative humidity to the region today and Thursday.
Relative humidity values this afternoon will fall below 30
percent across southern and central portions of the region, with
30 to 35 percent values across northern areas. Wind gusts today
could be up to around 15 mph across southern areas and up to
around 20 mph across northern areas. Afternoon relative humidity
values Thursday will generally range from 30 to 35 percent
across the region inland from the Downeast coast. Higher humidity
values will occur along the Downeast coast with onshore winds.
Southerly wind gusts of 20 to 30 mph are expected Thursday with
the strongest winds during the afternoon. Fire weather concerns
are possible both today and Thursday in areas with no snow
cover.
KEY MESSAGE 2...
Chance for low relative humidity and gusty winds Sunday
afternoon. This could lead to increased fire weather concerns in
areas with no snow pack.
KEY MESSAGE 2 DESCRIPTION...
NW flow aloft, with the region on the east (front) side of a
deep layered ridge, should allow for continued drying of the low
levels. As a result, have a 30-50% chance for relative humidity
levels less than 30% Sunday afternoon. In addition, a
tightening surface pressure gradient, and increasing winds in
the low levels results in a 30-50% chance of wind gusts greater
than 20 mph Sunday afternoon. The combination of these two
factors, could result in increased fire weather concerns Sunday
afternoon, especially in areas with no snow pack. This should
mainly be from the Central Highlands and Southern Aroostook on
south.
