Marine Weather and Tide Forecast for Machias, ME

NEAR TERM /THROUGH TONIGHT/
High pressure cresting to our south will bring a sunny morning today with a southwesterly breeze around the high. This will warm the air into the mid to upper 50s inland. Low pressure approaching from the west will result in increasing cloudiness this afternoon and some showers may begin to push into western areas very late in the afternoon.

Low pressure will begin to lift up to our northwest tonight drawing moisture north on a southerly wind. This will bring showers across the area, especially to central and northern parts of the region. There will be an initial band of showers in the evening ahead of a small upper level shortwave, then a break followed by more showers very late at night toward morning. The clouds and southerly wind will result in a mild night with lows near or just above 40 across the area. Rain will be a bit spotty due to its showery nature. Average rain amounts overnight will range from a 0.10 to 0.15 inch.

SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/
Rain showers will continue into Saturday morning as low pressure tracks well northwest of Maine. Showers will end in Bangor and Downeast by the afternoon, while the threat will continue in the North through the day. The other story on Saturday will be the warm air mass over the region. 850-mb temperatures will rise to 10-12C for Bangor and Downeast, and 7-10C further north. Skies are forecast to be mostly cloudy for much of the day. However, still forecasting highs in the 60s for most inland locations.
Areas from Bangor to Dover-Foxcroft will likely see highs in the lower 70s, with warmer readings possible if more clearing takes place. Southwest winds will keep the immediate coast cooler, with highs in the 50s.

A cold front will approach from the northwest by Saturday evening. This will bring the threat of rain showers from the Central Highlands northward. Soundings show some elevated instability over Northern Aroostook County. Confidence was high enough to introduce the mention of isolated thunder in the forecast there. Cannot totally rule out a rumble or two elsewhere. Temperatures drop quickly behind the front Saturday night. Lows will be in the 30s north of Moosehead Lake and Katahdin. To the south, expect lows in the 40s. Any leftover rain showers in the Crown of Maine will change to snow showers by early Sunday morning.

A blustery and colder day is on tap for Sunday thanks to an increasing pressure gradient. Based on mixed layer soundings, could see northwesterly wind gusts of 40-50 mph. Higher gusts are possible over the higher terrain. Still too early to consider wind headlines, but they may ultimately be needed.
Winds will diminish Sunday night with the loss of daytime heating and weakening pressure gradient. High temperatures on Sunday will be in the mid to upper 40s from Katahdin northward.
To the south, highs will reach the lower 50s.

LONG TERM /MONDAY THROUGH THURSDAY/
High pressure will dominate the weather for Monday, resulting in dry weather and lighter winds. A low pressure system will track into Quebec Monday night into Tuesday, before redeveloping along the coast by Tuesday night. At this time, thermal profiles suggest p-type will be rain. However, a few snowflakes could mix in over the highest terrain. Not expected to be a big rain producer, with amounts a half inch or less. An isolated rain shower will be possible over the North on Wednesday or Thursday.
Otherwise, dry weather and seasonable temperatures for that time period.
