AREA FORECAST DISCUSSION National Weather Service Albany NY 1024 PM EDT Fri Oct 30 2020

SYNOPSIS. High pressure will ridge in tonight with clearing skies and cold conditions overnight. The surface high will bring sunny, but cool weather and below normal temperatures on Saturday. The next cold front will bring a chance of showers back to the area Sunday afternoon into the early evening, followed by more unseasonably cold weather on Monday.

NEAR TERM /UNTIL 6 AM SATURDAY MORNING/. As of 1024 pm EDT . High pressure continues to build in from the Great Lakes Region with clear/mostly clear skies across most the region, except for a stubborn band of clouds just west of Albany and Glens Fall that extends southward into the Helderbergs and eastern Catskills, as well as the mid Hudson Valley. This maybe a weak convergent boundary in the wake of the mid and upper level trough, and this band of clouds should dissipate over the next few hours. The 00Z KALY sounding is very dry above 850 hPa and with a PWAT of 0.20".

The clear or mostly skies, light to calm winds and fresh snow cover will allow temps to fall into the teens and lower 20s with a few single digits in the southern Adirondacks. Some of the coldest readings may occur where the snow cover is slightly deeper still across portions of the Berkshires/Litchfield Hills and the eastern Catskills. We did lower mins some across the Lake George/Glens Falls area. We will also have to monitor for some patchy mist of freezing fog over shallow bodies of water or near the CT River Valley in southeast VT.

An SPS has been issued for patchy black ice expected except across the southern Adirondacks and western Mohawk Valley of southern Herkimer Co.

SHORT TERM /6 AM SATURDAY MORNING THROUGH MONDAY/. High pressure will ridge across the area on Saturday bringing sunny skies and unseasonably cool temperatures with highs ranging from upper 30s over the highest terrain, to the mid 40s in the Hudson Valley. Saturday night will be mostly clear and chilly. Southwesterly flow will begin to increase overnight around the west side of high pressure moving east of New England. The result may be that the lowest temperatures Saturday night will be in the evening, then temperatures may rise overnight.

Our next cold front will approach the area on Sunday. Clouds will increase and rain showers will overspread the area from west to east during the afternoon. High temperatures will range from the upper 40s to mid 50s, or near normal for the start of November. The cold front will move east of the area Sunday evening with showers ending, possibly as a brief period of snow showers over higher terrain. Much colder air behind this front will trigger the development of lake effect snow east and south of Lake Ontario by late Sunday night. At this point it appears that there will be enough of a northerly component in the flow to keep much of this snow west of our counties through Sunday night, however some small snow amounts may occur from the southwest Adirondacks south-southeast through the western Mohawk Valley and into the northern Catskills.

Monday will be a brisk and unseasonably cold day. The flow will become more westerly which would become increasingly favorable for lake effect snow in the western Adirondacks and could push a few snow showers east down the Mohawk Valley, but the atmosphere will be drying during this time so any snow accumulations west of the Hudson Valley should be on the light side. High temperatures on Monday will only be in the 30s to lower 40s.

LONG TERM /MONDAY NIGHT THROUGH FRIDAY/. Main story in the long term will be the transition from anomalous troughing to anomalous ridging, with the resulting weather becoming more settled and mild with time. Medium-range deterministic models and ensemble systems are showing good agreement in this pattern evolution. The period begins Monday night with a strong, northwesterly upper jet max diving into the base of the trough located over the Northeast states. Ascent associated with this process is expected to result in a clipper system moving through, enhanced by anomalously cold 850 mb air briefly cooling to near -10C moving over the warm Great Lakes. This has potential to bring some light to moderate accumulating snow and gusty winds Monday night, especially to areas north and west of Albany in the typical lake effect zones. Tuesday, the trough is modeled to quickly lift to the northeast, with ridging building in at the surface, resulting in a mainly dry but cool day. A flat midlevel ridge then takes over for the remainder of the week, with south to southwest flow at the surface to 850 mb ushering in anomalously warm air. The 850 mb temps may reach to near 10C, which is +1 to +2 standard deviations. Resulting high temperatures are forecast to be near normal on Wednesday and possibly close to 10F above normal Thursday and Friday, with the valleys possibly reaching into the 60s.

AVIATION /02Z SATURDAY THROUGH WEDNESDAY/. High pressure will build in from Great Lakes Region over NY and PA tonight. The surface high will slowly move east of New England tomorrow.

VFR conditions are expected the next 24 hours ending 00Z/SUN for KGFL/KALB/KPSF/KPOU. Some lingering clouds with bases 4-5 kft AGL are persisting in the wake of the mid and upper level trough over KPOU. These clouds should diminish the next few hours, as we are expecting mainly clear/clear skies shortly before or just after midnight. Radiational mist/fog is not expected with a dry air mass and very cold conditions tonight. The strong subsidence from the ridge will yield clear/mostly skies from the late morning through the afternoon.

The winds will be north/northwest at 5 kts or less early this evening, and then will be calm overnight. The winds will be southeast/south at 4-7 kts in the late morning through the afternoon on Saturday.

Outlook .

Saturday Night: No Operational Impact. NO SIG WX. Sunday: High Operational Impact. Windy With Gusts To 31 kts. Likely SHRA. Sunday Night: Moderate Operational Impact Breezy. Chance of SHRA. SHSN. Monday: Moderate Operational Impact. Windy With Gusts To 31 kts. Chance of SHSN. Monday Night: Moderate Operational Impact. Chance of SHSN. Tuesday to Wednesday: No Operational Impact. NO SIG WX.

FIRE WEATHER. Widespread precipitation across the area tapering off this morning from north to south. Fair but chilly weather Friday night into Sunday morning. Southerly winds increase Sunday ahead of a strong cold front with an increase chance for showers.

HYDROLOGY. Some ponding of water on roadways may occur this morning from a mix of snow and rain as the upper level trough approaches. Rivers and area streams will respond a little bit to the rainfall, however, no river flooding is expected.

Fair and chilly Friday night into Sunday as high pressure at the surface and aloft dominates our weather. Next chances for precipitation will come Sunday afternoon into Monday as a low pressure system approaches and moves across the region. Looking at rain and snow showers with this system.
