Area Forecast Discussion National Weather Service Binghamton NY 634 PM EST Thu Feb 20 2020

SYNOPSIS. A few lingering light lake effect snow showers will continue this evening before lifting north out of the area late tonight. High pressure builds across NY and PA this weekend with mild temperatures and fair weather. The pattern turns active next week with the potential for multiple low pressure systems.

NEAR TERM /THROUGH FRIDAY NIGHT/. 630 pm update . Just minor changes this evening. Light snow showers and flurries into Syracuse and Rome from Lake Ontario and more downwind of the Finger Lakes. Otherwise radar showing very little. Fewer clouds then forecast now. A little resurgence for clouds in CNY with a weak wave passing this evening. Lake effect will weaken late tonight and early Friday as high pressure nudges in and warmer air moves in aloft.

240 pm update . Main concerns in the near term remain focused around the persistent snow showers this afternoon dropping south across central/srn NY and spilling into the nrn tier of PA . then shifting back to the north for a brief period of time into the nrn Finger Lakes and wrn Mohawk Valley and srn Tug Hill this evening before moving out later tonight.

Broad upper level wave stretched out from the Northeast back to the srn Great Lakes moving slowly to the e/se this afternoon. Along and ahead of this wave an area of snow showers is being forced with the help of some weak BL instability . and producing light snow amounts and also mixing down some gusty 20-25 mph winds at times as well.

This diffuse area of snow showers will continue to drop south and diminish in intensity and coverage through the rest of the afternoon. High pressure begins to build in from the west this evening and winds will back to the w and eventually w/sw . which will shift the area of snow showers back to the north across the nrn Finger Lakes and wrn Mohawk Valley/srn Tug Hill area this evening. Additional snow amounts will be less than 1 inch with most of the snow done before midnight.

The drier air continues to move in overnight, which will allow the cloud cover to dissipate from south to north. Winds will weaken as well, and when combined with clearing skies will allow for rapid solar radiational cooling. Temperatures will fall into the single digits and lower teen above zero for most of the area, with a few below zero readings in far nrn Oneida County.

High pressure dominates the region tomorrow and tomorrow night with quiet weather, light sw winds and slightly warmer temperatures. Highs on Friday will warm into the upper 20s and lower 30s. Overnight lows Friday night will fall into the teens with another night of radiational cooling.

SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/. Overall, a very quiet short term period is in store as high pressure will be in control.

The center of high pressure will across the southern Appalachians Saturday, then offshore of the Carolinas on Sunday. However, its influence will extend well north to our area, with dry weather through the weekend. We can also expect temperatures starting fairly close to climatology, but trending higher as the southwesterly return flow of the departing high becomes more involved.

A weak disturbance riding over the high may allow some clouds to skim parts of Central NY Saturday, during otherwise benign weather as temperatures reach 30s to lower 40s. Upper teens-mid 20s Saturday night, will then be followed by upper 30s-upper 40s Sunday courtesy of warm air advection and a good deal of sunshine. Lower elevations of Northeast PA could even get around 50 degrees. Still quiet Sunday night, with lows of 20s to lower 30s.

LONG TERM /MONDAY THROUGH THURSDAY/. 230 PM Update . Overall, not much has changed with the long term period. Still looks like the pattern becomes more active as the week progresses. Made minor changes to POPs, but otherwise the forecast remains largely unchanged.

500 AM Update . Mild southwesterly flow dominates early next week, ahead of an amplifying trough that is projected to drop into the western Great Lakes by Wednesday. This could lead to colder weather advancing into our region beyond that timeframe, but until then above average temperatures are anticipated with precipitation chances mainly in the form of rain as weak waves run through the southwest flow. Most areas Monday and Tuesday will reach well into the 40s for highs; perhaps even lower 50s for some lower elevations of Northeast PA.

As temperatures drop beyond midweek, precipitation type will become more complicated, and there will be prospects for deeper low pressure systems within our region.

AVIATION /00Z FRIDAY THROUGH TUESDAY/. Some lake effect moisture is still affecting northern terminals with some light snow showers and MVFR conditions at times. High pressure will build in from the south tonight and clouds are expected to dissipate. Expecting VFR conditions everywhere through the period by midnight or just after midnight tonight.

Outlook .

Friday evening through Sunday . Mainly VFR expected.

Monday . Restrictions in rain showers possible.

Tuesday . Potential for scattered restrictions in rain and/or snow showers.

BGM WATCHES/WARNINGS/ADVISORIES. PA . None. NY . None.
