Area Forecast Discussion National Weather Service Binghamton NY 346 PM EDT Mon Jul 29 2019 .SYNOPSIS... Isolated thunderstorms will end by early evening. A cold front will slowly move through the region Tuesday and Wednesday with showers and thunderstorms. High pressure builds into the region for Thursday and Friday with drier and cooler weather. && .NEAR TERM /THROUGH TUESDAY NIGHT/... Local radars show isolated to scattered thunderstorms over the region which will quickly dissipate by early evening with loss of diurnal heating. Overnight will be mainly clear and warm with lows ranging in the mid 60s to lower 70s. On Tuesday, a prefrontal trough will cross the area during the afternoon and evening. Models indicate the atmosphere will be moderately unstable during the afternoon although shear values are weak. Mid level lapse rates are also fairly weak but mid level flow suggest strong wind gusts would be possible in some storms. Precipitable water values are also significant running around 1.50-1.80. Will mention gusty winds and heavy downpours during the afternoon and evening convection. Both SPC and WPC has area in marginal for the convective and excessive rainfall outlook. The most widespread coverage is expected across central New York and the northern tier of Pennsylvania. Highs on Tuesday will range in the mid to upper 80s. Tuesday night...By late evening the intensity of the convection will weaken due to loss of diurnal heating and passing short wave. Will continue with chance POPs after midnight as upper level trough and surface cold front approach area. Low will range in the mid to upper 60s. && .SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/... 345 pm update... Main concerns in the short term are focused on the potential for showers and thunderstorms along a trailing cold front/upper trough which will be exiting the area to the east during the day Wednesday. Quiet weather with high pressure building in on Thursday. Will likely be seeing a few scattered rain showers and embedded weak storms Wednesday morning associated with an incoming upper s/w and disorganized surface cold front draped across the region. However, as the day progresses, the atmosphere will become increasingly unstable...especially east and south of the front. The best chance for thunderstorms into the afternoon will be east/se of a line from Elmira to Rome/Utica...with the threat for storms continuing to shift east through the afternoon. Highs will top out in the upper 70s and lower to mid 80s. Most of the convection will die down after sunset Wednesday evening with the cooler and drier air advecting in as well, helping to stabilize the air mass. Temps will drop into the upper 50s and lower 60s Wed night. High pressure is expected to dominate the region on Thursday with a much drier air mass keeping skies mostly sunny and allowing temperatures to warm into the lower 80s. Quiet weather continues Thursday night with maybe some valley fog and temperatures bottoming out in the mid 50s to lower 60s. && .LONG TERM /FRIDAY THROUGH MONDAY/... 345 pm update... A boundary over the mid Atlantic region may reach north into ne PA with a few showers and storms on Friday, but confidence is not very high with respect to precip chances Fri or Friday night. May see a few afternoon/evening pop-up showers and storms on Saturday...but with minimal impacts. Then on Sunday, a weak cold front drops in from the north and will likely act to increase cloud cover, but a few light showers/storms are not out of the question. Overall, weather conditions will be on the warm and dry side going into the weekend. Warming temperatures into the 80s, with isolated to scattered late-day convection possible. && .AVIATION /20Z MONDAY THROUGH SATURDAY/... VFR conditions primarily expected through this TAF period. Until early evening ceilings around 4K feet with isolated to scattered thunderstorms. Thunderstorms only included in the KRME/KSYR terminal where coverage may be more significant. Included a two hour tempo group for MVFR thunderstorms, 20Z-22Z at KSYR and 21Z-23Z at KRME. Overnight just scattered high clouds. On Tuesday, a prefrontal trough will cross the terminals during the afternoon/evening with brief MVFR/IFR restrictions in thunderstorms along the boundary. Since activity not expected until after 18Z not included. Southwest winds 5-10 knots becoming light and variable overnight. Southwest winds on Tuesday around 10 knots. Outlook... Tuesday night through Wednesday...Restrictions likely in showers and thunderstorms. Thursday through Saturday... Mainly VFR. && .BGM WATCHES/WARNINGS/ADVISORIES... PA...None.
