Update... A cold front will cross the region overnight with partly cloudy skies along with isolated to scattered showers across northern areas, with partly cloudy/mostly clear skies across the remainder of the region. Low temperatures will range from around 40 to the mid 40s north, to the upper 40s to around 50 Downeast. Have updated the forecast to adjust for current conditions along with overnight temperatures, cloud cover and shower chances. Previous discussion... Friday will be a nice day although it will be a little cooler as a drier airmass on NW winds moves into the region. It will be mostly sunny with breezy NW winds and temperatures trending about 10 to 15 degrees cooler.

&& .SHORT TERM /TONIGHT THROUGH SUNDAY/... Our dry and mild weather will continue through the weekend as a strong ridge high pressure builds in from the west. Friday night will be mainly clear with lows from the low 30s north to the upper 30s Downeast. High pressure both surface and aloft building onto the east coast will then bring plenty of sunshine Saturday as highs reach the 50s north and low 60s Downeast. Sunday will be even warmer as the upper level ridge builds over with highs in the 60s throughout the area. However, some moisture topping the ridge combined with a bit of warm advection sliding north behind the surface high pressure may produce some mid and high cloudiness, especially across the north, on Sunday. && .LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/... A southerly flow will increase Sunday night into Monday as high pressure moves to our east into the open Atlantic. Dry weather will persist into early Monday. A band of moisture may then approach late Monday along a boundary between departing high pressure and a large trough approaching from the upper Midwest. Some showers will become possible late Monday into Monday night along this boundary. The midwestern trough will intensify and deepen on Tuesday as the high to our east anchors in place. This will result in a strengthening gradient between the high to our east and the trough pushing in from the west, and as a result, an increasing south wind Tuesday into Tuesday night. Some showers, possibly heavy, may occur along the front as it pushes in from the west Tuesday night, and south winds may become very strong by Tuesday night. The front is expected to push to our east later Wednesday into Wednesday night. There continues to be a possibility that a secondary low will form along the front off the southeast coast and race north, possibly bringing rain, late in the week. && .AVIATION /05Z FRIDAY THROUGH TUESDAY/...
