AREA FORECAST DISCUSSION National Weather Service Albany NY 112 PM EST Tue Dec 10 2019

SYNOPSIS. Along with a mild start, a cold front will pass through the region today with some rain showers. Behind the cold front, colder air will return to the region through the afternoon and some lingering moisture will allow for a period of light snow for tonight into early Wednesday for far southern areas. With much colder air back into the region, some lake effect snow will develop for northern and western parts of the area for late Wednesday through early Thursday.

NEAR TERM /UNTIL 6 PM THIS EVENING/. As of 1230 PM EST . Enhanced area of rainfall along the cold front was progressing through the Mohawk Valley, Lake George Saratoga Region and southern Vermont. Winds quickly shift toward the WNW with a gradual decrease in temperatures. Reports of dense fog near the frontal zone which is also confirmed by the NY Mesonet web cam network, however, it appears rather brief until the fropa. So main update was to increase PoPs for the next few hours with the frontal passage, updated wind shift timing, minor tweaks to the hourly temps/dewpts. Cold front still on schedule to pass through our southern areas around 6 PM.

SHORT TERM /6 PM THIS EVENING THROUGH THURSDAY NIGHT/. As the front continues to slowly sag south and east offshore the western Atlantic for tonight, a wave of low pressure will move up the boundary. This wave of low pressure, aided by a strong 170+ kt jet streak over the Northeast will allow for some additional precip tonight into early Wednesday. Models have come into agreement that most of this precip will be south of the region, but a period of light snow is expected across the Catskills, mid Hudson Valley, southern Taconics, southern Berkshires and NW CT. Initially, the boundary layer may be warm enough for this precip to be rain, but it should quickly cool to allow for precip to be snow across our area by 10 PM to Midnight. Although snowfall rates don't look excessive, steady light snow is expected for late tonight through mid-morning on Wednesday. Total snow for the southeastern Catskills, mid Hudson Valley, southern Berkshires and southern Taconics will be about a coating to two inches (locally up to 3 inches in southeastern Dutchess County). Meanwhile, NW CT should see two to four inches of snowfall, so have included them in a Winter Weather Advisory. This snowfall will impact the morning commute on Wednesday, allowing for hazardous travel due to snow covered roads and low visibility.

Elsewhere, skies will be clearing out as temperatures falling for tonight. Lows will be in the teens and 20s, with the coldest temperatures across the Adirondacks where skies will clear out first. Any untreated surfaces that remain wet from earlier rainfall may become slick due to temperatures below freezing so caution will need to be taken for those venturing out tonight.

On Wednesday morning, any lingering light snow across southeastern areas will be ending, and skies will continue clearing across the entire area. It will be noticeably colder for Wednesday with highs only in the mid 20s to mid 30s. Winds will be increasing through the day and it will be breezy by late in the day, making it feel even colder.

Much colder air will be arriving aloft for Wednesday evening into Wednesday night as a secondary boundary passes through the region. 850 hpa temps will be as low as -18 C across northern areas by late Wednesday night behind this northern stream clipper system. This will set the stage for rounds of both lake enhanced snow showers along the frontal boundary and also true lake effect snowfall behind the front.

The initial band of lake enhanced snow showers will be located northwest of the area across the St. Lawrence Valley and northwestern Adirondacks, but will start shifting towards our area after 00z Thursday. 00z HREF suggest snowfall rates may exceed 1" per hour as the band reaches the western Adirondacks, but the band should be moving fairly quickly thanks to the shifting winds, so snowfall totals at any one location look limited, with just one to three inches for the western Adirondacks (including the Old Forge area).

Behind the initial band of lake enhanced snow, another band of lake effect snow will develop within the northwesterly flow for the Mohawk Valley for later Wednesday night. This band of snow could have an upstream multi-lake connection and could reach across the entire Mohawk Valley and possibly into the Capital Region as well. Accumulation looks to be coating to an inch or two, with the highest totals in western areas. Some lake effect may linger into Thursday morning, but should be decreasing in intensity and extension as inversion heights start to lower thanks to an approaching area of high pressure. Overnight lows on Wed night look to be in the teens for the whole area.

On Thursday into Thursday night, dry weather (after any lake effect ends) is expected for the entire region thanks to a strong area of high pressure passing across the area. Skies should be fairly clear, but temps will remain cold. Highs will be in the 20s and remain below freezing for the entire region on Thursday. Lows look to fall into the teens for Thursday night.

LONG TERM /FRIDAY THROUGH MONDAY/. Activity pattern. Guidance continues its agreement on the development of a complex system which is expected to impact the region over the weekend. However, there remains plenty of differences amongst the models regarding the evolution of the system and how much northern and southern interaction there is and cyclogensis potential. As this time, there is agreement the flow is progressive. Have followed a blended forecast approach favoring guidance from the Weather Prediction Center to maintain forecast consistency. Please refer to the Extended Forecast Discussion issued by Weather Prediction Center for their insight. Have brought likely pops into the southeast portion of the forecast area Friday evening with these pops spreading across the rest of the area overnight into Saturday morning. At this time, it appears rain and snow initially eventually changing over to all rain Saturday as temperatures rise. Unsettled weather is expected the rest of the weekend with showers on the backside of the system. Above normal temperatures expected to continue Sunday but not a mild as Saturday with seasonable readings retuning for the start of the new work/school week.

AVIATION /18Z TUESDAY THROUGH SUNDAY/. A cold front is working through the terminals. Just passing KGFL and on top of KALB. The front will reach KPSF by 19Z, and KPOU by 21Z.

Ahead of the front have included a couple hour period of LLWS at KPOU and KPSF given weak surface winds and strong southwest winds at 2000 feet.

Convective cells (ex lightning) have been noted with the frontal passage. So have included an IFR period of RA with FROPA.

As the front shifts south, its progress will slow as a wave rides along the front. The combination of the wave and colder air seeping in behind the front will allow for a period of IFR snow at KPOU tonight. A period of snow is likely for KPSF tonight as well. For now, have called it MVFR, although not out of the question that KPSF could get into some IFR SN. No mention of SN at KALB and KGFL. It's possible KALB could see a period of light snow as well tonight, but chances too small to include.

Outlook .

Wednesday Night: Moderate Operational Impact. Chance of SHSN. Thursday: Low Operational Impact. Slight Chance of SHSN. Thursday Night: No Operational Impact. NO SIG WX. Friday: No Operational Impact. NO SIG WX. Friday Night: Moderate Operational Impact. Likely RA. Saturday: High Operational Impact. Likely RA. Saturday Night: Moderate Operational Impact Chance of SHRA. RA. Sunday: Moderate Operational Impact. Breezy Chance of SHRA.

HYDROLOGY. Temperatures have warmed well into the 40s across most of the area, with dewpoints into the 40s as well. Along the milder temperatures have been periods of rainfall, with MRMS estimating 24 hour rainfall totals already in excess of one inch across the Adirondacks and southern Green Mountains. The combination of a melting snowpack and rainfall has lead to significant runoff, which is allowing for rises on rivers and streams. Some rivers are starting to reach action stage and a few rivers across western New England and far eastern New York (such as the Mettawee and possibly the Hoosic and Walloomsac) could reach flood stage today into this evening. Elsewhere, ponding of water in expected, especially in urban areas, thanks to the melting snow and rainfall. This will especially be in true in areas where drainage is blocked by snow piles. Most areas will only see additional rainfall today about about a tenth of an inch, although some high terrain areas could locally see as much as a third of an inch.

As temperatures cool off, runoff should slow down for tonight into tomorrow. Some additional precipitation in the form of snow is expected for southern areas, but this will not have any immediate impact on rivers and streams. For the remainder of the work week, rivers and streams will recede. However, another storm may bring more moderate to significant rain to the region for the weekend, which will cause rivers and streams to rise once again.

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