Marine Weather and Tide Forecast for Eagle Lake, ME

NEAR TERM /THROUGH SATURDAY/
645PM Update: No major changes to the forecast for this update.

Low pressure tracks across the eastern Great Lakes tonight, drawing a warm front north toward the Downeast coast. Aloft, the supporting upper low also crosses the Great Lakes tonight.
Isentropic lift will help support rain expanding across the region tonight, with the better rain chances across northern and central portions of the forecast area. The system slowly approaches the forecast area later Saturday while starting to vertically stack beneath the supporting upper low. The warm front will lift to the Downeast region Saturday before stalling, though exactly how far north the front reaches is still uncertain. Rain will develop across the entire forecast area Saturday with the approaching surface/upper lows. The rain could be heavy at times Saturday, particularly across central and Downeast portions of the forecast area. Low temperatures tonight will range from around 40 to the lower 40s north, to the lower to mid 40s Downeast. High temperatures Saturday will range from the upper 40s north to around 50 Downeast.

SHORT TERM /SATURDAY NIGHT THROUGH MONDAY/
Saturday night, the main low will move northward along the Maine coastline, bringing an inverted trough over the north.
This will provide a slight break in precip Saturday evening, with rainfall returning late Saturday night. Rain rates will then increase on Sunday morning as the low begins to move eastward and cold air filters in behind the system, increasing instability, primarily over the western areas. Rain could be mixed with snow in the far western Maine mountains, but most people across the forecast area will only see liquid precipitation. Overall rainfall totals through the weekend will be upwards of 1.5 inches, which will really be beneficial for fire weather conditions and help raise river flows as well.

Rain showers will continue Sunday afternoon in the unstable air behind the low. As the low moves eastward, showers will also move across the forecast area and skies will clear for a dry Monday. Temps on Sunday will be slightly cooler than normal with the widespread rain showers and cooler air mass. However by Monday, the return of a warmer air mass and abundant sunshine will raise high temps into the 60s across the region.

LONG TERM /MONDAY NIGHT THROUGH FRIDAY/
Dry weather will continue Monday night and Tuesday before another low approaches Tuesday night, increasing the chance for precip. Temps will be unseasonably warm on Tuesday, with highs in the upper 60s or approaching 70 for the entire area except the Downeast coast. This will generate some strong low level lapse rates and as the cold front approaches, the chance exists on for a thunderstorm or two over the eastern Maine-Canada border early Wednesday. By Wednesday evening, the cold front will have moved through and upper level ridging will move in for a dry Thursday.
