AREA FORECAST DISCUSSION National Weather Service Albany NY 336 PM EST Sat Jan 18 2020

SYNOPSIS. A fast moving storm system heading into the region from the Great Lakes will bring steady snow across the region into tonight. Some snow will continue across northern high terrain areas on Sunday, with blustery conditions for the entire area. Dry and cold weather will be in place for much of the upcoming week.

NEAR TERM /UNTIL 6 AM SUNDAY MORNING/. WINTER STORM WARNING REMAINS IN EFFECT FROM 1 PM THIS AFTERNOON TO 7 PM EST SUNDAY FOR:

Herkimer, Hamilton and northern Fulton counties of eastern New York, and Bennington and western Windham Counties in southern Vermont, The Lake George Saratoga region of eastern New York, eastern Windham County in southern Vermont, Berkshire County in western Massachusetts, and northern Litchfield County in northwest Connecticut .

WINTER WEATHER ADVISORY REMAINS IN EFFECT FROM 1 PM THIS AFTERNOON TO 1 AM EST SUNDAY for:

Snowing across the region and latest soundings show most of the saturated layer from the surface through midlevels is just under the layer of DGZ. Some -FZDZ/-FZRA in western NY associated with the nose of the boundary layer thermal ridge due to south winds and associated warm advection. This is apparent in the 18Z KBUF sounding and the 16Z KBGM NASA Impacts project sounding as well as some of the NY Mesonet profiler data.

So, as the isentropic lift and warm advection increases the remainder into this evening, the lower layers will warm and the snow to liquid ratios will be near climatology or just below climatology. Snow flakes outside the office and on NY State Mesonet web cams show very small snow flakes with few if any large dendrites. Some frontogenesis indicated in sources of guidance in the 850-700 hPa layer and 700-500 hPa layer but the zone of enhanced frontogenesis is quick to exit this evening. Enhanced upslope flow into the southern Adirondacks, northern Saratoga Region, southern Green Mountains and northern Berkshires will result in localized heavier snowfall.

Some downslope flow will cause some reduction in snowfall in the Hudson Valley between the Capital Region and mid Hudson Valley while some mix with very light freezing drizzle and freezing rain this evening will reduce snow amounts in the mid Hudson Valley to areas near and south of the MA/CT border. Headlines remain the same as snow totals in sources of guidance still consistent with multiple previous versions. So, steady snow ending this evening along and south of the Mohawk Valley to Berkshires but lingering in northern areas most of the night. Transition to snow showers as steady snow ends. Winds becoming gusty toward daybreak could result in blowing and drifting of snow.

Text forecasts will include additional snowfall only because the snow has started everywhere. However,the WSW and web graphics will indicate the storm total snowfall to match the headlines.

Temperatures will rise slowly through the night as the low level thermal ridge tracks into the region. So, temperatures should rise well into the 20s by daybreak but around 30 to lower 30s Hudson Valley to NW CT and southern Berkshires.

SHORT TERM /6 AM SUNDAY MORNING THROUGH TUESDAY/. Upper energy exits through the day Sunday with strong west to northwest boundary layer flow turning to north by late in the day. Upper energy and lake effect moisture will result in some fairly widespread snow shower activity into the southern Adirondacks and upslope into the southern Green Mountains. Some line segments of snow showers could accompany the leading edge of the deeper cold advection and boundary layer wind shift to north. So, indicating isolated to scattered snow showers in many areas outside of lake effect and upslope. Highs in the 30s but 20s northern areas and near 40 southern areas. Winds will be gusty to 35 mph or more in some areas. Whatever snow is on the ground will drift in the morning but areas that get above freezing will see less blowing and drifting.

Deep cold advection Sunday night through Monday night. Winds will diminish later Sunday night and through the day Monday. Highs Monday in the 20s to near 30 but teens northern areas. Weak warm advection begins Tuesday but with the low level ridging overhead and light winds, temperatures will not warm much. Highs in the 20s to near 30 with teens in northern areas.

LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/. A dry pattern is in store for much of the long range period. The next system may return next weekend with mixed rain/snow.

High pressure will build across the eastern United States Tuesday night into Wednesday and remain the dominant feature through Friday. This will result in generally dry weather across the region with a gradual rise in temperatures throughout the period. With enough cold air to start, lake-effect snow showers off Lake Ontario will continue to affect parts of the Adirondacks Tuesday night, but will come to an end Wednesday morning. Highs Wednesday will range from the 20s in the higher elevations to the low to mid-30s in the valleys. By Friday, temperatures will range from the 30s in the higher elevations to the low to mid-40s in the valleys.

By Saturday, forecast models indicate a closed upper-level low tracking across the Midwest while a possible dual-low forms at the surface (one across the Ohio Valley and another off the mid-Atlantic coast). This will bring the return of clouds and precipitation. Current thermal profiles suggest mixed rain/snow is possible. With this storm several days away, changes to its track and potential p- types are likely to occur in future model runs. Regardless, allowed for at least chance pops with this Saturday system.

AVIATION /21Z SATURDAY THROUGH THURSDAY/. Snow is tracking northeastward towards the TAF sites as of 18z. Initially, the terminal airports should brief periods of light to briefly moderate snow with breaks of dry weather at times. However, the main area of moderate to heavy snow is on track to impact the region between 21z and 03z today with IFR visibility and ceilings likely. After 03z, the steady snow should end (except at perhaps GFL where light snow may linger overnight) but spotty freezing drizzle may ensue. We still do not have enough confidence to include freezing drizzle at this time so we included VCSH and kept MVFR visibility and ceilings in place to lingering low clouds and patchy fog.

Light southeast winds this afternoon should strengthen heading towards 00z ranging between 5-10kts. Winds then should become southerly towards 06z and eventually southwesterly. Towards 14z, winds shift to the west and become gusty by late morning sustained between 10-15kts with gust up 25-30kts.

Outlook .

Sunday Night: Low Operational Impact. Breezy NO SIG WX. Martin Luther King Jr Day: No Operational Impact. NO SIG WX. Monday Night: No Operational Impact. NO SIG WX. Tuesday: No Operational Impact. NO SIG WX. Tuesday Night: No Operational Impact. NO SIG WX. Wednesday: No Operational Impact. NO SIG WX. Wednesday Night: No Operational Impact. NO SIG WX. Thursday: No Operational Impact. NO SIG WX.

HYDROLOGY. Fast moving storm system will spread widespread snowfall to the region through tonight, with some lingering snow across the Adirondacks and Greens into Sunday. Nearly all the precip will be frozen and total liquid equivalent will be 0.25 to 0.75 inches. This snowfall won't have any immediate impact on rivers and streams.

Behind this storm system, dry and cold weather is expected into much of the upcoming week. This will allow river ice to form and strengthen on areas bodies of water.
