As of 957 AM EDT Saturday...Quick update to the forecast this morning to adjust PoPs and temps based on current surface obs , radar , and satellite trends. Latest radar shows morning showers have dissipated with more isolated coverage currently, and satellite tells the tale of the lack on instability with several wave clouds noted and only slightly glaciated cloud tops. RAP analysis additionally shows mid-level heights are slowly rising, indicative of the base of the upper trough lifting northward. All this said, feel coverage for this morning is going to be more isolated , and then scattered this afternoon with the most numerous showers and isolated thunder across the northern tier zones. Temps were also knocked down a few degrees based on current obs and expected cloud cover, with highs mainly in the 60s, touching 70 in the Champlain and lower CT Valley. Previous discussion... Some showers have continued through the overnight as base of upper trough and center of upper low shifts over the North Country. We should have a break in the showers later this morning as shortwave energy pushes out of our forecast area. But, expect diurnally driven showers once again this afternoon with a slight chance for thunderstorms as well. With cold pool aloft under upper level low which will remain stationary over our region through Sunday, there will be a chance for showers with thunderstorms possible each afternoon. Could also see some small hail with thunderstorms, but strong winds should not be a concern. Showers will decrease in coverage after sunset both this evening and Sunday evening. Surface temperatures will be cooler than normal during the day and near normal overnight. QPF will vary quite a bit, but some areas will have heavier rain if they have multiple thunderstorms at one location. From today through Sunday average rainfall will be around a quarter of an inch to three quarters of an inch, with locally higher amounts.

&& .SHORT TERM /SUNDAY NIGHT THROUGH MONDAY NIGHT/... As of 344 AM EDT Saturday... Unsettled weather will continue as a closed upper low over the region slowly meanders eastward. Showers will be diurnally driven for the most part, with increased areal coverage in showers during the afternoon before dwindling during the evening hours. Temperatures during the day on Monday will continue to be on the cooler side, with highs in the 60s to low 70s. Overnight lows will be near seasonal, with temperatures in the mid 40s to mid 50s. && .LONG TERM /TUESDAY THROUGH FRIDAY/... As of 344 AM EDT Saturday...A break in the unsettled pattern can be expected for mid-week as the closed upper low pushes away and a period of surface high pressure builds across the region. Cooler temperatures will trend towards seasonal normals, with highs on Tuesday in the mid to upper 70s before warming into the upper 70s to lower 80s for the second half of next week. Overnight low temperatures will largely be in the 50s for most of next week. Unsettled conditions will return as another upper- level trough swings through, although there is still plenty of uncertainty regarding timing so largely stuck to NBM guidance with some chances for precipitation starting Thursday into next weekend. && .AVIATION /14Z SATURDAY THROUGH WEDNESDAY/...
