000 FXUS61 KCAR 241949 AFDCAR Area Forecast Discussion National Weather Service Caribou ME 305 PM EDT TUE MAY 24 2016 .SYNOPSIS... Low pressure across southern new england will lift north tonight. A cold front will cross the area wednesday and will be followed by high pressure thursday. A warm front will lift north across the region friday. && .NEAR TERM /THROUGH WEDNESDAY/... Low pressure at the surface and aloft near Cape Cod late this afternoon will track northeast across the Gulf of Maine tonight. Increasingly moist air will be advected north across the region tonight resulting in stratus clouds moving north from the Gulf of Maine overnight. As the upper/surface lows move northeast, there could even be a few showers from time to time tonight, mainly across central and downeast areas. Lows tonight will be in the 50s. The upper low will exit to our east early Wednesday as the next upstream short wave and cold front approaches from the west. Expect showers and a few thunderstorms to develop across northern areas by Wednesday afternoon and then move into downeast areas by late in the day. Highs on Wednesday will range from the mid to upper 70s northern and central areas, low to mid 70s interior downeast, and low to mid 60s along the downeast coast. && .SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY/... A cold front crosses the cwa Wednesday night with scattered showers and the chance of an evening thunderstorm, especially for northern and central portions of the cwa. The last of the showers should end by around midnight with at least partial clearing overnight. Ridging both surface and aloft will build across the state Thursday making for a dry day with sunshine and temperatures a bit above average. The ridging breaks down Thursday night and a warm front will bring the chance of showers back to the region, especially late evening and overnight. Friday will likely feature more clouds than sun and it will be mild and moderately humid with a few showers around at times. && .LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/... The longwave pattern features a western conus trough with another trough in the maritimes over the weekend that moves out into the north Atlantic early next week. Mid to upper level ridging will be found across the Mid Atlantic into New England. The air mass will be warm, but flow at times off the relatively cold ocean waters will keep temperatures cooler along and near the coast. It will remain unsettled as disturbances move through the mean flow which will produce clouds and showers at times. The good news, it appears a cold front drops south across the area Saturday evening that will likely make Sunday a mostly sunny and dry day with comfortable humidity levels. There is also a decent chance that Memorial Day will be dry, with the chance of an afternoon shower mainly across northern and western portions of the cwa. && .AVIATION /18Z TUESDAY THROUGH SUNDAY/...
