As of 118 PM EDT Friday...No changes needed to the forecast for this afternoon. A weak front continues to track east of the region and in it`s wake we`ve got a gorgeous day with partly sunny skies, temps in the 70s, and very comfortable humidity. Enjoy! Clear skies again tonight and a weakening pressure gradient will promote more efficient cooling with lows mainly in the 40s to around 50 degrees. While chances are very low, some of the coldest hollows could dip into the 30s and may have a little frost; this would be only possible in typically colder spots in the Northeast Kingdom and the Adirondacks. For Saturday, temperatures will cool another degree or two for the daytime highs keeping conditions feeling pleasant. Late in the afternoon, rain chances begin to increase west to east as a weak boundary tracks into the western reaches of northern New York.

&& .SHORT TERM /SATURDAY NIGHT THROUGH SUNDAY/... As of 346 AM EDT Friday...Shower chances peak Saturday night as a decaying boundary tracks west to east through the North Country. Can`t rule out a stray rumble of thunder mainly across northern New York late in the evening. QPF will be meager as the parent low stacks barotropically in north-central Canada with upper level support lifting north of the Canadian border; not a recipe for strong forcing or heavy rainfall. Still a few hundredths of an inch of rain are possible. Temperatures will be mild overnight with lows likely in the 50s and warming into the mid/upper 70s for Sunday; a few 80 degree temperatures are possible in southern Vermont and portions of the Champlain Valley. && .LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/... As of 346 AM EDT Friday...Models have been favoring a more potent system to move into the Northeast on Memorial Day bringing chances of more widespread thunderstorms and potentially heavy rainfall. Projections are for a digging longwave trough to tap into some southern US moisture and advecting it northward. Upper level support isn`t overly robust, but low level jet signatures do warrant some consideration. 850mb jet is on the stronger side for this time of year with 50-60kts across model suites; PWATs are anomalous as well - above 1.5" suggesting heavy rainfall should thunderstorms form. Synoptic QPF signatures are not overly wet, but still could contribute 0.5-1.25" of liquid depending on which model verifies best. WPC has included the Northeast in a Marginal Risk for flash flooding, or about a 5% chance. We`ll be keeping a tab on Monday watching this system`s evolution. Otherwise, conditions will likely remain unsettled with broad longwave troughing highly favored to linger through much of next week. This pattern supports cooling temperatures back to seasonal averages in the upper 60s to low 70s with showers possible each day. && .AVIATION /18Z FRIDAY THROUGH WEDNESDAY/...

Through 12Z Saturday...VFR conditions will prevail through the period with a low probability for fog at KSLK overnight. Otherwise, fair weather clouds across the region this afternoon will trend to SKC towards sunset, continuing overnight, with just some high clouds approaching from the west Saturday morning. Higher aviation impact will continue to be the winds this afternoon, gusting 20-25kts from the WNW, which won`t abate until after 00Z when winds will trend light and variable thereafter. Variable winds at 6kts or less are expected for Saturday. Outlook... Saturday: VFR. NO SIG WX. Saturday Night: Mainly VFR, with local MVFR possible. Chance SHRA, Slight chance TSRA. Sunday: VFR. Slight chance SHRA. Sunday Night: VFR. NO SIG WX. Memorial Day: Mainly VFR, with local MVFR possible. Chance SHRA, Slight chance TSRA. Monday Night: Mainly MVFR, with areas IFR possible.
