Area forecast discussion, Jun 22, 2:00 PM EST, 3 hours 50 minutes before
Area Forecast Discussion National Weather Service Binghamton NY 300 PM EDT Mon Jun 22 2020 .SYNOPSIS... A slow moving storm system will keep scattered thunderstorms over NY and PA through Wednesday. && .NEAR TERM /THROUGH TUESDAY/... 150 PM update... Unstable air over the western forecast area with CAPE values approaching 1500 j/kg will continue to trigger scattered thunderstorms through the afternoon hours. Little shear exists, so we expect the main threat with thunderstorms to be brief downpours and gusty winds. A slow moving wave of low pressure will track across Southern Ontario Tuesday. A trough associated with this cyclone will bring an area of thunderstorms into NY and PA during the late afternoon hours. Isolated showers or thunderstorms will pop up ahead of the trough earlier in the day, but coverage will remain low until the trough approaches. Again, we expect good instability values by little in the way of shear. Temperatures will rise to between 85 and 90. Thunderstorms will taper off to showers Tuesday night. Temperatures will drop into the middle 60s. 1130 AM update... Convection triggered over the southwestern corner of Bradford County in the last half-hour. We expect additional thunderstorms to form after noon, but activity will be scattered. Moderate CAPEs and low shear point toward short-lived cells with brief downpours. && .SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY/... 3 pm update... Cold front pushes east of the area Wednesday morning, but broad upper level low pressure system will remain nearly stationary over Southern Ontario Canada, with troughing over the Northeast U.S. Temperatures will be considerably cooler, with highs Wednesday afternoon only in the 70s to maybe low 80s in some of the warmer spots. The cool upper level low will remain nearly stationary through the period. With the upper low in our vicinity, can't rule out isolated to scattered thunderstorms during peak heating in the afternoon. Wednesday night will be cool with shower and thunderstorm activity diminishing around sunset. On Thursday, as the upper low continues to spin in southern Canada, a weak perturbation rotates around the base of the of the low/upper trough Thursday afternoon and this may be enough lift enhance afternoon showers and thunderstorms, but confidence remains low on this feature and have kept PoPs at low chance for now. && .LONG TERM /THURSDAY NIGHT THROUGH MONDAY/... 400 am update... The upper low over the nrn Great Lakes will begin to move east Thursday night and Friday but not before triggering yet another round of afternoon showers and storms on Friday. Instability and deep moisture will be limited, so the precip probabilities are on the lower end of the spectrum. Temperatures on Friday will be a few degrees warmer than Thursday with highs topping out in the upper 70s and lower 80s. Weak upper ridging will begin late Friday into Saturday morning ahead of the next wave, which is forecast to be more progressive and sweep through late Saturday into Sunday. This system will be capable of producing more showers and storms this weekend. Another ridge of high pressure will begin to build northward across the ern US going into the start of next week with the hot and humid conditions likely returning to a good portion of the Northeast. && .AVIATION /19Z MONDAY THROUGH SATURDAY/... We expect mainly VFR conditions through Tuesday afternoon. The exceptions will be late this afternoon when isolated thunderstorms could affect the terminals, mainly west of I-81, and early Tuesday morning, when low stratus could bring MVFR or fuel alternate ceilings to KAVP, KBGM, and KELM. Another round of thunderstorms is expected Tuesday afternoon. Outlook... Tuesday afternoon through Friday...Daily chance of afternoon showers and thunderstorms with associated brief restrictions. Best chance on Tuesday and Wednesday. Late night early morning valley fog at KELM. && .BGM WATCHES/WARNINGS/ADVISORIES... PA...None. NY...None. && SYNOPSIS...DJP NEAR TERM...DJP SHORT TERM...MPK LONG TERM...BJT AVIATION...DJP
