&& .NEAR TERM /THROUGH TONIGHT/...
-- Changed Discussion --
A cold front across northern Maine early this morning will push south to the Downeast coast this afternoon, and will move offshore tonight. A weak wave will track along the front and across parts of the Downeast Region today. High pressure over Hudson Bay will build into northern Quebec today and into western Labrador tonight. The ridge will extend south into Maine tonight. Isolated showers in far northern Maine will wind down early this morning. Showers will fall in spots Downeast this morning and into at least the first half of the afternoon with drier air to filter in late in the day. The last several runs of the HRRR and RAP indicate more widespread showers from around Dover-Foxcroft and Bangor and into much of Hancock County later this morning into the afternoon. Have increased the PoPs and coverage a bit today, and it is possible that the PoPs might need to be increased even further once we get a better handle on just where the showers will fall. Clouds will give way to breaks of sun this afternoon as it turns less humid. Across the north, early clouds and isolated showers and patchy fog will give way a mostly sunny day with low humidity and a north wind of 10 to 15 mph with a few gusts to 20 to 25 mph. Highs will range from the mid 60s north to the low 70s in the Greater Bangor area. Clear and cool tonight with some frost across the colder northwest valleys. Have added in some patchy frost. It is iffy as to whether there will be any frost in eastern Aroostook County and will hold off on any frost headlines for now as patchy frost is only in the grids for an hour, and only in some of the lower spots, but this is something that will need to be monitored. There may also be a bit of fog in the river valleys for an hour or two around sunrise.

&& .SHORT TERM /SUNDAY THROUGH MONDAY/...
-- Changed Discussion --
Fair weather is expected Sunday as high pressure builds across the area. The high will slide east of the Canadian maritimes Sunday night. The high will continue to move east on Monday as a cold front approaches from the west. There will be the chance for showers across northern and western areas Monday afternoon in advance of the approaching front. Highs on Sunday will be in the mid to upper 60s and in the low to mid 60s on Monday.

&& .LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
-- Changed Discussion --
The cold front will cross the region Monday night with the chance for showers. Tuesday will be a dry day with mainly sunny sky conditions and seasonable temperatures. Continued fair and seasonable weather is expected Tuesday night and Wednesday. Thursday is still shaping up as a very warm day as H925 mb temperatures approach 23 to 24C with high temperatures potentially climbing well into the 80s. The ridge moves offshore Friday allowing a southerly flow to transport moisture back into the region by late week.

Brief MVFR conditions are possible late this morning into mid afternoon at KBGR and KBHB in clouds and a few showers. Otherwise, VFR expected today and tonight. Patchy late night river valley fog possible just prior to sunrise Sunday morning, which may locally cause IFR conditions, but they are not expected to be widespread. SHORT TERM: Generally VFR through the period. The exception will be Monday night when a cold may bring MVFR/IFR conditions to the region.
