.SYNOPSIS... Dry and seasonal conditions will persist through tonight before an upper level disturbance brings increased cloud cover on Saturday and the chance for light rain showers Saturday night into Sunday. No significant precipitation is expected with any of these showers, so drought conditions will continue. Prolonged dry weather prevails for next week with temperatures warming above seasonal normals by mid- week.
&&
.NEAR TERM /THROUGH TONIGHT/... As of 156 AM EDT Friday...Not much to talk about for the next 24 hours through tonight as surface high pressure will continue to dominate the weather across the North Country and Vermont. Clear skies this morning will trend partly sunny this afternoon as some high cirrus begin to stream in ahead of an approaching shortwave trough, becoming partly to mostly cloudy tonight. No precipitation is expected and temperatures will be seasonally warm today in the low to mid 70s, and milder tonight than the previous nights in the 40s to lower 50s.

.SHORT TERM /SATURDAY THROUGH SUNDAY/... As of 156 AM EDT Friday...For this weekend, trends in model guidance continue to indicate less chances for any widespread precipitation as a closed upper low over James Bay no longer looks to dig southward towards the forecast area. Instead, a more east/southeast track to the Gulf of St. Lawrence is now the consensus, leaving the CWA on the southern periphery of the upper trough as it weakens through Sunday. Dry antecedent conditions will really limit any precipitation development with virga or a few spits of light rain possible Saturday. The best chance for showers come Saturday night into Sunday morning along the trough passage, but even then, the system lacks any depth of moisture so only some isolated to widely scattered showers seem possible with QPF generally less than a tenth of an inch. One model outlier though, the experimental RRFS, and to some extent the GFS, try to develop some terrain enhanced showers across the Adirondacks and southern Vermont Sunday afternoon that could produce a bit more QPF so that`s something to consider if more hi-res models show this potential in the next 24 hours. Temperatures for the weekend will be seasonal with highs ranging through the 70s, and lows mainly in the 50s.
&&
.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/... As of 156 AM EDT Friday...The extended forecast returns to dryness. Deep, tilted high pressure will gradually push east in no rush. Temperatures will begin to warm from the 70s Monday/Tuesday, and up into the mid 70s to lower 80s midweek. We`re likely to remain stuck beneath ridging. Despite some diverging modeled patterns beyond midweek, the different scenarios mostly depict dryness.
&&
.AVIATION /06Z FRIDAY THROUGH TUESDAY/... Through 06z Saturday...The main aviation concern for the next 6 hours is fog developing in climatologically favored locations, like KSLK and KMPV. Some fog may develop at KEFK as well, but incoming dry air could preclude formation. Flow will be light and variable through about 14z before trending north to northwest before again turning light and variable. Incoming high clouds will likely limit fog beyond 06z Saturday.
Outlook...
Saturday: VFR. Slight chance SHRA. Saturday Night: VFR. Chance SHRA. Sunday: Mainly VFR, with local MVFR possible. Slight chance SHRA. Sunday Night: VFR. NO SIG WX. Monday: VFR. NO SIG WX. Monday Night: VFR. NO SIG WX. Tuesday: VFR. NO SIG WX.
