AREA FORECAST DISCUSSION National Weather Service Albany NY 747 PM EST Mon Nov 30 2020

SYNOPSIS. Scattered showers this evening 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 TONIGHT/. Wind Advisory remains in effect until 10 PM for the central/southern Taconics, southern Green Mountains, Berkshires, and Litchfield County .

As of 7:30pm EST, a line of heavy rain with a few rumbles of thunder that moved through the eastern Catskills, Capital District and western New England has weakened and is exiting to our east with just some scattered showers in its wake. The best moisture transport has now shifted into New England and so has the the potential for heavy rain and any thunderstorms. With our parent low now closed off and becoming vertically stacked overnight, southerly winds in the system's warm sector will advect in a mild air mass. Therefore, in addition to lingering isolated to scattered showers and cloudy skies expect temperatures to actually increase overnight. Temperatures will stay into the mid to upper 50s with even low to mid 60s in the mid-Hudson Valley and Litchfield County, CT.

Winds in our wind advisory area have remain below advisory criteria for the most part but decided to keep the advisory in place until our next update time at 9:30PM given NYS mesonet observation in the Taconics still around 30-40mph.

SHORT TERM /TUESDAY 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 /01Z TUESDAY THROUGH SATURDAY/. VFR ceilings currently in place at GFL and ALB with MVFR ceilings at PSF and POU. Visibilities have improved to VFR at all sites and are expected remain as such overnight. Ceilings at GFL and ALB expected to drop back to MVFR by 03 UTC with all TAF sites remaining MVFR overnight. There is potential for some brief period of IFR ceilings 09 - 12 UTC mainly at GFL but we did not have enough confidence to include at this point.

Ceilings should become scattered to broken tomorrow with even potential breaks of sun. However, with intermittent showers still possible, we maintained MVFR ceilings until after 18 UTC when there is more confidence that VFR ceilings finally return.

South to southeasterly winds will remain sustained 5 - 10kts overnight but strengthen by 15 - 18 UTC to be sustained 8 - 15kts as the occluded boundary progresses through the area. LLWS tonight should only last through 06 - 09 UTC when the low-level responsible for 2 kft winds 35 - 45kts should exit out of our area.

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.
