Area Forecast Discussion National Weather Service Binghamton NY 1038 AM EDT Thu Aug 13 2020

SYNOPSIS. High pressure will control our weather into the weekend keeping central New York and northeast Pennsylvania generally dry and temperatures near normal. The weather will become increasingly unsettled early next week as a system approaches our area from the midwest and southeast U.S.

NEAR TERM /THROUGH TONIGHT/. 930 am update . made just a few minor tweaks to grids with latest CAMS guidance. Based on CAMs it looks like our southern zones which is the northern Poconos gets grazed by convection late this afternoon. Model soundings for the NAM shows enough low-level moisture for parcels to clear an inversion around 700 mb at KAVP and KMPO. Farther north, the drier low-levels inhibits parcels from breaking through and hence it will be dry. So we have mainly slight chance to low chance POPs for a time late afternoon across our far southern zones . i.e the northern Poconos which matches up with our neighboring WFOs well. Pretty much this is in line with previous forecast. The winds are light and there is a lot of dry air with weak forcing so not expecting anything severe, or any heavy rainers.

Previous Discussion . High pressure over the Great Lakes will slowly build into the region keeping the area dry and seasonable. Exception may be over the Poconos where some return easterly flow could bring a few showers or even a stray thunderstorm. Otherwise just some high clouds are possible from systems passing well to the south.

SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/. Weak high pressure extending down from Eastern Canada will bring quiet weather to NY and PA Friday night as temperatures fall into the 60s.

A wave of low pressure extending from the Great Lakes to the Mid-Atlantic region will pull moisture into NY and PA Saturday and Saturday night. This will set off widely scattered showers or thunderstorms.

Temperatures will climb into the lower 80s Saturday under partly sunny skies, then fall into the 60s Saturday night as clouds increase.

LONG TERM /SUNDAY THROUGH WEDNESDAY/. The models continue to disagree on the fine points of the long term forecast. A trough over central and eastern sections of Canada will bring somewhat cooler air into NY and PA. But it remains unclear whether this pattern change will be dry and pleasant or showery.

Our latest forecast calls for scattered showers and thunderstorms for the start of the week, then drying conditions for Tuesday and Wednesday.

AVIATION /15Z THURSDAY THROUGH MONDAY/. General VFR conditions are forecast through the period. High pressure and light winds are expected with no ceilings.

Outlook .

Friday . Mostly VFR expected . possible valley fog at ELM overnight.

Saturday and Sunday . Early morning fog possible, especially for KELM.

Monday . Restrictions possible in scattered showers and thunderstorms.

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

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. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
