AREA FORECAST DISCUSSION National Weather Service Albany NY 1236 AM EST Tue Dec 1 2020

SYNOPSIS. Scattered areas of rain this evening capable of brief heavy downpours will weaken overnight to isolated showers. Temperatures remain mild tonight and Tuesday with some lingering rain showers during the day. Cooler conditions return for mid week, along with scattered rain and snow showers.

NEAR TERM /THROUGH TODAY/. Area of showers from the Schoharie valley through the western Capital Region extending through the Ventral Mohawk Valley into the southern Adirondacks. The showers are moving north and will affect these areas and move into the Lake George Saratoga Region as well. Clouds are breaking up to some degree in the eastern Catskills, mid Hudson Valley and NW CT. Some of these breaks could intermittently get to the southern Berkshires and Taconics through daybreak. Temperatures will hold steady in the 50s to lower 60s or fall just a degree or two.

Previous AFD has a few more details through the day and is below .

The system's cold front is not expected to pass through the region until tomorrow morning so areas from the Capital District south and east will remain in the warm sector overnight leading to mild and even muggy conditions. Temperatures should stay in the 50s to even low 60s in this region with dew points in the in the mid to upper 50s. The combination of muggy conditions and light wind has led to some fog formation tonight. This should linger until 06 - 09 UTC when winds should finally increase enough to scour out the fog. If fog become dense and widespread enough before that time, we may need to issue a Special Weather Statement to alert users to reduced visibilities.

SHORT TERM /TONIGHT THROUGH THURSDAY/. Additional showers are possible on Tuesday as the main upper low moves through New York. Best chances look to be across northern areas, closest to the low center. Highs on Tuesday will be realized early in the day as the leading edge of cold air moves into the region ahead of the front. Many could see the temps either staying steady or dropping throughout the day.

Lows Tuesday night will drop below freezing everywhere.

The cold front moves through late Tuesday into Wednesday. Rain/snow showers will be possible with the frontal passage during this time with the southern Adirondacks possible seeing advisory level snowfall. Highs on Wednesday will be seasonable, in the low 30s to low 40s.

Dry weather returns Wednesday night through the day Thursday. This is a brief reprieve in between northern stream systems. Highs on Thursday warm a few degrees into the mid 30s to mid 40s.

LONG TERM /THURSDAY NIGHT THROUGH MONDAY/. High degree of uncertainty/low confidence forecast for much of the long term, especially regarding any potential phase interaction between northern and southern stream energy next weekend into early next week.

Before any possible interaction, departing upper level low from midweek continues to drift farther north into east central Canada, with decreasing influence on our region Thursday night. Still some clouds/snow showers possible across portions of the SW Adirondacks, otherwise lingering clouds likely across at least central and northern portions of the region. Near seasonable temperatures, with lows Thursday night mainly in the mid 20s to lower 30s, although may be slightly warmer where clouds persist.

Then, northern stream energy approaches from the Great Lakes region for Friday-Monday, while southern stream energy ejects east/northeast toward the mid Atlantic/southeast coast. Although 12Z/30 ECMWF and FV3 suggest little, if any interaction between these two disturbances until well offshore, several 12Z/30 GEFs members, and the 12Z/30 GEM still suggest greater chances for interaction and potential storminess next weekend. Will therefore keep slight chance to low chance PoPs throughout this period due to the uncertainty, with the possibility of a more significant storm system still within reasonable probabilities. This portion of the forecast will be greatly subject to change until better sampling of individual disturbances as this week progresses.

With the threats for precipitation, will keep showery wording for now, with a slight edge on the assumption that precipitation will be forced mainly by the approach of northern stream disturbance and some added Lake enhancement. P-type mainly snow for higher elevations, with snow during the night for valley areas, and rain/snow mix for valleys during the daytime hours.

Temperatures should cool closer to seasonable levels through the period, with daytime highs mainly in the mid 30s to lower 40s, although perhaps colder by next Monday (20s for higher elevations, 30s for most valley areas). Overnight lows mainly in the mid 20s to lower 30s.

AVIATION /06Z TUESDAY THROUGH SATURDAY/. Midlevel dry slot has brought an end to the steadier/heavier rainfall, with just a few showers still around primarily along/north of I-90. Surface low pressure is now moving north of the area, and drier air is gradually mixing in from the south. This likely means that KPOU/KPSF will remain above IFR conditions for the rest of the night, and we may see some gradual improvement at KALB/KGFL especially after 09Z.

On Tuesday after daybreak, a pocket of colder air aloft moving in from the south will likely result in BKN-OVC skies continuing, but cigs are expected to rise to low VFR for most of the day. An upper level disturbance combined with diurnal heating is expected to result in scattered showers, especially from the mid-morning into the afternoon. Not enough confidence to highlight a period for flight category reductions, but this will be evaluated with the next TAF cycle. MVFR cigs/vsby appear possible in showers. Showers will tend to diminish Tuesday evening.

Winds will become southerly through the night tonight, continuing southerly with some gusts to 20 kt during much of the day Tuesday. Some lingering low level wind shear conditions are possible through 09Z or so at KGFL.

Outlook .

Tuesday Night: Moderate Operational Impact. Chance of SHRA. Wednesday: Low Operational Impact. Slight Chance of SHRA. Wednesday Night: No Operational Impact. NO SIG WX. Thursday: No Operational Impact. NO SIG WX. Thursday Night: No Operational Impact. NO SIG WX. Friday: Low Operational Impact. Slight Chance of SHRA. Friday Night: Low Operational Impact Slight Chance of SHRA. SHSN. Saturday: Moderate Operational Impact Chance of SHRA. SHSN.

HYDROLOGY. A moderate rainfall event continues through this evening. So far, rainfall reports have ranged from 0.25" in the southern Adirondacks up to 1.5" in the eastern Catskills. Additional rainfall will occur through this evening before tapering off to light showers overnight. Some urban/poor drainage flooding has already occurred in Ulster county so that threat will also continue into this evening. Flash flooding is not expected. However, isolated thunderstorms are possible this evening which may result in brief, heavy rainfall.

River rises are expected, but likely will remain within bank. Current forecasts indicate river levels may reach action stages on the Hoosic River at Williamstown, and also Stevenson Dam on the Housatonic.

For details on specific area rivers and lakes, including observed and forecast river stages and lake elevations, please visit the Advanced Hydrologic Prediction Service /AHPS/ graphs on our website.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
