&& .SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SATURDAY/... Variable cloudiness will persist across the region overnight with lows ranging through the 20s from north to south. Trough of low pressure will approach from the northeast on Saturday. Any sunny breaks in the morning will quickly give way to mostly cloudy skies and scattered snow or rain showers in the afternoon. Best chance precip will be in eastern zones but expect any QPF to be on the light side. Will see slightly cooler highs with temps ranging through the 30s to near 40 in the south. && .LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/... Upper level low pressure will slowly move southward across the forecast area Saturday night. Forcing for ascent should be sufficient and focused enough to allow for a band of southwestward-moving snow showers to traverse the forecast area during the evening hours. They may be briefly heavy with accumulations up to an inch possible. In addition, gusty northeast winds are expected Saturday night and Sunday...with gusts around 30 mph possible. Thereafter, fair weather is currently expected for much of the upcoming week as the area will be sandwiched between low pressure systems to our east and west. This will allow for warmer temperatures too, with highs in the 40s and 50s midweek. && .AVIATION /13Z FRIDAY THROUGH TUESDAY/... Short Term...VFR today. VFR overnight with areas of MVFR ceilings in the north. Areas of MVFR/IFR ceilings and vsby Saturday...mainly in the afternoon. Long Term...Areas of IFR/MVFR conditions in snow showers Saturday night. Improvement to VFR is foreseen later Saturday night and Sunday. && .MARINE... Short Term...Continuing SCA`s but will likely be dropping headlines with the morning update. Long Term...SCA conditions will occur Saturday night through Monday as northeasterly winds strengthen. A period of low-end gales will be possible Sunday - but probability for a sustained period of G35kt is currently low. && .GYX WATCHES/WARNINGS/ADVISORIES... ME...None. NH...None.
