NWS Binghamton, NY wrote its last area forecast discussion before the first event at Jun 26, 12:54 PM EST, 43 minutes earlier.
AREA FORECAST DISCUSSION National Weather Service Binghamton NY 154 PM EDT Wed Jun 26 2019 .SYNOPSIS... A warm and mostly dry day is in store. However, with an unstable atmosphere in place, a passing disturbance will cause scattered gusty thunderstorms this afternoon into evening. Thursday through early Friday will be quiet, but another chance of showers and thunderstorms returns Friday afternoon, as well as over the weekend at times. && .NEAR TERM /THROUGH THURSDAY/... With the early afternoon update, a look of the mesoscale models has allowed for a refined window for timing of scattered showers and thunderstorms this afternoon. Timing looks to be from 2-4 pm in the Finger Lakes and Syracuse regions and closer to the 4 pm timeframe across the Southern Tier. Mixed layer CAPE advection into western NY of around 1,000 J/KG currently will build east. This coupled with steep low level lapse rates in place already across the region will provide enough instability. However, shear continues to look very marginal for strong storms today with less than 30 knots of 0-6 KM shear. Brief heavy downpours and lightning look to the main threats with storms from from this afternoon into the early evening. AN inverted-V sounding profile still suggests a threat for gusty winds with a few storms. 310 AM Update... Main near term concern is potential for scattered gusty thunderstorms from mid-afternoon through early evening, as a passing disturbance harnesses a warm and unstable atmosphere. A weak and temporary surface ridge is currently in charge early this morning, with clear sky and very patchy fog in some of the valleys. Despite good radiational cooling, dewpoints are holding up enough to prevent temperatures from falling below mid 50s-mid 60s to start the day. Abundant sun will have no problem quickly warming us up, to highs in the lower to mid 80s; even a few upper 80s in lower elevations of Northeast PA. The atmospheric column today will contain instability yet also a fair amount of dry air. Models continue to depict a weak wave traveling through divergent flow aloft during peak diurnal heating hours. The overall dryness of the air mass will limit coverage of the thunderstorms that develop. However, with steep lapse rates/inverted-V appearance in the lower portion of the model soundings all the way beyond 750mb, along with dry air entrainment within any convection; there is good potential for cool pools and mixing down of gusts in the cells that move across the area mid afternoon through early evening. Timing of the wave suggests that thunderstorm chances may be highest in Central NY east of I-81, though our whole general area could see at least isolated to scattered thunderstorms. The Storm Prediction Center continues to advertise a marginal risk of severe thunderstorms for our area, primarily due to the potential of strong wind gusts though isolated hail cannot totally be ruled out especially if a NAM-like scenario pans out. As if often the case, the NAM is more bullish in terms of Convective Available Potential Energy, getting around 1500 J/kg. Other models are in the upper hundreds to around 1000 J/kg. The isolated to scattered storms will scoot quickly southeast this evening, which will lead to dry conditions overnight through Thursday, especially with flat thermal ridging inhibiting any additional convection. Temperatures will settle to upper 50s-lower 60s for lows tonight, followed by highs Thursday once again in the lower to mid 80s except for some upper 80s in lower elevations of Northeast PA. && .SHORT TERM /THURSDAY NIGHT THROUGH FRIDAY NIGHT/... High pressure to our south should keep us dry overnight and into Friday morning and warm southwesterly flow will keep lows in the low 60's for most locations. Friday, the forecast becomes a bit more uncertain and confidence is low at this time for severe storm potential late Friday afternoon through Friday night. However, some model guidance is indicating favorable ingredients for severe weather. NAM/GFS/Euro all show shortwave pushing east across the Great Lakes with slight timing differences. Out ahead of this wave, conditions should be quite unstable, with most guidance forecasting over 1000 K/kg of CAPE and mid-level lapse rates over 7C/km. The timing of shortwave will likely be the key if severe weather is to occur, but there is also some concern of a late night MCS pushing eastward, as the 0Z NAM indicates. Still way too early to jump on any one solution, but will have to monitor to see how the forecast unfolds the next 48 hours and there is potential the severe threat will increase for Friday evening/night && .LONG TERM /SATURDAY THROUGH TUESDAY/... Not much changing in the long term period. An unsettled weekend is still expected across our region, but models still have slight timing and location differences with upper low dropping south out of Ontario on Sunday. How wet we will be this weekend will depend on the track of this system, as the GFS is currently drier than Euro, as it is a bit further east with the low. High pressure moves in for the start of next week. Large ridge sets up over the Eastern U.S., but our area will likely remain on the periphery of the ridge axis. Any waves coming up and over the ridge could bring showers and storms back on Tuesday. && .AVIATION /18Z WEDNESDAY THROUGH MONDAY/... Mainly VFR throughout the TAF period. Main concern will be the coverage and intensity of any thunderstorms this afternoon. Any thunderstorm looks to be brief with only scattered coverage limiting the TAFS to tempo groups only. The latest data has allowed for a updated timing window at all NY TAF sites. For KRME, KITH and KSYR the main window looks to be from 19-21Z. However, as of 18Z a few thunderstorms have already developed between KITH and KSYR. It can not be ruled out that a thunderstorm moves in a little before 19Z as a result. Coverage looks slightly later in the 20-22Z window at KBGM and KELM. At KAVP, coverage looks more on the isolated side, no so tempo group for thunder at this time. VFR tonight with lighter winds, potential brief window for fog at KELM around sunrise Thursday. VFR on Thursday as well with winds increasing to around 10 knots. Outlook... Thursday through midday Friday...Mainly VFR. Friday afternoon through Sunday...Occasional chances for scattered showers-thunderstorms and associated restrictions. Sunday night and Monday... VFR. && .BGM WATCHES/WARNINGS/ADVISORIES... PA...None. NY...None. && SYNOPSIS...MDP NEAR TERM...MDP/MWG SHORT TERM...MPK LONG TERM...MPK AVIATION...MWG
