.DISCUSSION...
Southerly winds will increase this morning and peak midday into
the afternoon. Gusts will reach 15-25mph at times with a few
higher gusts to 30mph possible especially along and southeast of
the Longfellow Mtns including Aroostook County. Afternoon
relative humidities will drop to 40-50 percent in Eastern
Aroostook, Baxter Region into portions of the Central Highlands
and interior Downeast north of Route 9. These areas will be the
greatest fire weather concerns. RHs will be 50-55 percent across
the North Woods and 60-80 percent thanks to a seabreeze Downeast.
Showers and thunderstorms developing late over the Maine and
Quebec border later this afternoon, continuing into Monday and
Tuesday. The trend for this system has been drier and drier, with
the only wetting rains expected along the mountains and northwest
to the Quebec border including the North Woods and St. John
Valley. Elsewhere, rainfall generally 0.1 to 0.2 inch expected
including Eastern Aroostook, Upper Penobscot Valley, Bangor
Region
and Downeast.
Drier weather, lower RHs and steady light winds are possible
Tuesday through Thursday. Only a few shower chances mainly in the
North Woods and far North.
