...Heavy Rain Expected Across Most of Northern and Eastern Maine

through Saturday with Heaviest Rain Totals over the Central Maine

Highlands...

...Rain Changing to Wet Snowfall Mostly over High Terrain across

Northwest and Central Highlands of Maine Late Morning into

Afternoon...

Rainfall totals with this current rain event will range from

about 0.75 inches across Washington County upwards to 2.5 to 3.0

equivalent inches over the northwest and central Maine highlands

(where moderate to heavy rain banding will linger the longest) by

Saturday evening. Hunters and campers should be alert for high

stream flows and even possible minor stream flooding by Saturday

afternoon especially over the northwest and central highlands.

In addition to heavy rainfall, colder air on brisk northwest winds

wrapping in behind developing low pressure tracking over southeast

Maine will result in a change over to wet snow over the northwest

and central highlands beginning as early as mid Saturday morning

at higher terrain near the Quebec border, and by early to mid

Saturday afternoon over the central highlands and higher terrain

of north central Aroostook. One to three inches of very wet

snowfall is possible at and above 1200 feet MSL, with even higher

snow totals possible over high mountain summits (refer to the

recreation forecast under PWMRECCAR for details) by Saturday

evening.

Those wanting to brave the elements overnight through Saturday

will need clothing and camping equipment to deal with heavy

rainfall, falling temperatures with brisk winds, and possibly

even mountain snowfall.
