NWS Binghamton, NY wrote its last area forecast discussion before the first event at Aug 3, 2:12 PM EST, 2 hours 17 minutes earlier.
Area Forecast Discussion National Weather Service Binghamton NY 312 PM EDT Sat Aug 3 2019 .SYNOPSIS... Scattered thunderstorms have popped up this afternoon from the southern tier and Catskills in New York into northeast Pennsylvania. Sunday will be mainly dry with partly to mostly sunny skies and maybe a few showers or thunderstorms popping up from the NY/PA border on south. High pressure builds in Sunday night. && .NEAR TERM /THROUGH SUNDAY NIGHT/... Showers and thunderstorms will continue this afternoon with a weak surface trough over the region. A few storms may contain heavy downpours and strong gusty winds, with DCAPE values near 1000 J/kg. With the loss of heating this evening, showers and storms should dissipate rather quickly. A cold front will push down from the north overnight and into Sunday morning. This front could have a few light showers along it through the overnight hours, but mostly just thinking an increase with clouds more likely as it pushes in. For tomorrow, the cold front will be along the NY/PA border and a weak shortwave pushes across our area late in the morning through early afternoon. This could help kick off a few showers and possibly a thunderstorms, but forecast soundings indicate very dry air aloft, so coverage of any showers and storms will be much less than today. Skies will start to clear from north to south late tomorrow after through evening as high pressure builds in from the north. A fairly cool airmass will settle overhead and lows could did into the upper 40s across parts of the Catskills by early Monday morning. && .SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/... Still looking mainly dry for Monday with high pressure in control - though the GFS and Euro start to bring in slight chance POPs into NE PA early Monday evening as the surface high pushes eastward. However, the better consensus among the rest of the guidance continues to be a dry day with a slight chance for showers slowly starting to work back later Monday night as we get into the return flow behind the exiting system. Temperatures Monday should be more or less seasonal, peaking generally in the low to mid 80s before falling back into the low 60s Monday night. Increasing chances for showers and storms are expected Tuesday as a weak shortwave looks to move through the area out ahead of the main trough situated over the upper Great Lakes. With MLCAPE up to 500-1000 j/kg and PWATs up to 1-1.5in, some heavy downpours and gusty winds would not be out of the question in storms. Otherwise, temperatures look to rise a couple degrees warmer Tuesday with highs generally in the mid 80s before falling back into the 60s overnight. Showers continue into Tuesday night with the approaching frontal system Wednesday. && .LONG TERM /WEDNESDAY THROUGH SATURDAY/... The rest of the work week is looking unsettled with chances for showers and thunderstorms each day. A frontal boundary will slowly pass through the area Wednesday, providing somewhat better chances for showers and storms. A more unstable airmass and deep layer speed shear still at around 20-30kts are indicating better chances for storm organization as the frontal boundary tracks through Wednesday. Through the end of the week, a 500mb trough remains situated over the region, and any weak ripples passing through the flow will keep chances for spotty showers and storms in the forecast. Dry weather finally looks to return for Saturday as high pressure builds in once again. Temperatures for the rest of the extended stay generally in the upper 70s and low 80s for highs and the low 60s for lows - though Saturday should turn a couple degrees cooler. && .AVIATION /19Z SATURDAY THROUGH THURSDAY/... A weak disturbance is kicking off showers and t'storms this afternoon. Look for storms to dissipate around or just after sunset with the loss of heating. Generally, these showers and storms will remain south of SYR, RME and probably ITH and they will only have a chance to cause just brief restrictions at ELM, BGM, and AVP. Valley fog redevelops late tonight and could impact KELM once again, mainly through the early morning hours on Sunday. Outlook... Sunday through Monday...VFR other than potential predawn fog each morning at KELM. Isolated showers possible KELM-KBGM-KAVP on Sunday. Tuesday and Wednesday...Restrictions possible in scattered thunderstorms. && .BGM WATCHES/WARNINGS/ADVISORIES... PA...None.
