&& .SHORT TERM /SATURDAY NIGHT THROUGH MONDAY/... A weak area of high pressure will be across the north Sunday evening. Clouds will increase as moisture, cascading over the top of the ridge, begins to approach ahead of a warm front. This will be followed by a mostly cloudy day on Sunday. Low pressure lifting west of the area Sunday will continue to draw moisture north along the warm front bringing rain across the north with just a chance for some showers Downeast. Showers will likely continue overnight Sunday night, especially over central and northern areas. By Monday, the warm front will be north of the area and warm and very humid air will be across the region as low pressure tracks well to the north. Lots of moisture in the region will keep skies mostly cloudy and a few showers may still be around. An isolated thunderstorm is possible, mainly during the afternoon. Sounding profiles show some weak shear but also weak capes around 100 j/kg with limited heating. The humid air moving in over the cooler waters will likely result in some fog along the coast on Monday. && .LONG TERM /MONDAY NIGHT THROUGH FRIDAY/... Showery weather will continue through Tuesday as a couple of shortwaves will slide across the region. Ridging builds in thereafter, leading to a dry spell Wednesday and Thursday. Low pressure will cross to our north on Friday while dragging its attendant cold front across northern New England. There`s some disagreement between the long-range models as to the strength and timing of this front, but at the least expect we`ll see some showers as it goes through. Temperatures will be warmest earlier in the period; Tuesday`s highs will top out in the 80s across the Central Highlands down through interior Downeast, while elsewhere should see mid to upper 70s. Highs will mainly be in the 70s thereafter, though the coast will remain cooler Thursday and Friday owing to onshore flow. && .AVIATION /00Z SATURDAY THROUGH WEDNESDAY/... NEAR TERM: Restrictions will remain MVFR and possibly IFR overnight. Saturated low levels may result in low stratus and fog at all terminals tonight before improving to VFR by mid-morning. SHORT TERM: VFR to MVFR conditions are expected Saturday night. MVFR to IFR conditions are expected on Sunday then IFR to LIFR conditions in low clouds and some fog are likely Sunday night in Monday. && .MARINE... NEAR TERM: Seas and winds will remain below SCA through tomorrow. Areas of fog will develop over the waters tonight. SHORT TERM: Winds and seas are expected to be below SCA saturday night through Sunday night. Winds may reach SCA in gusts over the offshore waters on Monday. Very humid air over the waters may result in areas of dense fog on Monday. IFR conditions will give way to VFR through the day Tuesday. VFR will prevail Tuesday night and Wednesday. && .CAR WATCHES/WARNINGS/ADVISORIES... ME...None.
