What forecasters said that day
The local office's own words before this small craft advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Buffalo, NY wrote its last area forecast discussion before this small craft advisory went out at May 23, 2:09 AM EDT, 2 hours 36 minutes earlier.
Area forecast discussion, May 23, 2:09 AM EDT, 2 hours 36 minutes before
Area Forecast Discussion National Weather Service Buffalo NY 209 AM EDT Thu May 23 2019 .SYNOPSIS... Showers and strong thunderstorms will increase in coverage area across the region today, ahead of a cold front that will sweep across the area later this afternoon and early evening. Warm and humid conditions today will be replaced by cooler, and less humid conditions for Friday...in generally rain free weather. The next weather system will bring more showers Friday night to our area, with showers and thunderstorms again passing over the area Saturday. && .NEAR TERM /THROUGH TODAY/... Initial round of showers have passed across our region this early morning, with now a brief clearing trend developing. Light southerly winds will continue through the remainder of tonight. Given the overall warm advection regime...lows tonight will be substantially warmer than those of the past couple of nights... with minimum temperatures ranging from the lower 50s across the North Country to near 60 along the Lake Erie shoreline. On Thursday the warm front and any isolated attendant showers/storms will finish pushing across our area during the morning...and may be followed by a brief relative lull for a few hours. After that time... the combination of diurnal heating/destabilization of an increasingly warm and more humid airmass within the warm sector...increasing height falls aloft...and the approach of a prefrontal trough should lead to renewed convective development by late morning or midday...with this initially developing and focusing to the southeast of the stabilizing influence of Lake Erie...before growing/pushing northeast across the Genesee Valley/Finger Lakes and into the North Country during the early to mid afternoon hours...with the bulk of this then sliding east of our region late. Given the combination of favorable moisture...lift...and instability that is expected...have further increased PoPs associated with this round of convection to the lower end of the categorical range. With respect to the potential for strong to severe storms...a strengthening westerly flow regime aloft will lead to copious amounts of shear areawide...with 0-6 km bulk shear values of at least 50 knots expected...and some the short term guidance suggesting that this could reach as high as 60-70 knots. With respect to instability...diurnal destabilization out ahead of the prefrontal trough is currently projected to lead to the MUCAPE values of 1000-1500 J/kg in those areas south of Lake Ontario away from stabilizing lake influences...with localized pockets of 1500-2000 J/kg possible. Such a combination of shear and instability should lead to the development of increasingly organized convection and an attendant risk for all forms of severe weather. Of these...damaging wind gusts and large hail would be the primary threats by far...though the amount of available shear and low LCL heights would also be supportive of a small...but nonzero risk for a tornado. Given all this...the current Slight Risk of severe storms advertised in SPC's Day 2 Convective Outlook looks very reasonable... particularly from the Southern Tier eastward across the Finger Lakes where the shear-instability parameter space appears most favorable. Behind the prefrontal trough and its attendant convection...increasing drying and subsidence will make for a much less favorable environment for additional convection...and as such would expect the trailing cold front (as is so commonly the case for our area) to produce little more than some isolated to scattered showers as it works into far western New York late in the day. The bigger story in the wake of the prefrontal trough will actually be a brief but notable period of stronger southwesterly to westerly winds downwind of Lake Erie...where downward transport of higher momentum air from aloft should lead to a round of 15-30 mph sustained winds along with gusts to 40-45 mph during the early to mid afternoon hours...with these then quickly subsiding as we head toward evening. && .SHORT TERM /TONIGHT THROUGH SUNDAY NIGHT/... The forcing responsible for the active weather Thursday afternoon will quickly exit our region Thursday evening...as a 45-50kt low level jet and deep moisture profile ahead of a cold front will make its way across New England. While there may be some leftover showers and thunderstorms early in the evening due to the actual cold frontal passage...the trend will definitely be for benign weather with dying convection rapidly giving way to partial clearing. In fact...all of the forecast area should be precipitation free by midnight. Meanwhile...the somewhat muggy conditions (dew points in the 60s) will be replaced by a more comfortable Canadian airmass with Tds falling back into the low 50s by daybreak. Ridging at all levels will build across the Lower Great Lakes on Friday. The strong subsidence provided by the ridge and the proximity of being under the right front exit region of a 150kt H25 jet will nearly guarantee dry weather with abundant sunshine. It will be notably cooler (by more than 10 deg f) than Thursday though...as a Canadian airmass with single digit H85 temps will only allow afternoon mercury readings to be in the mid to upper 60s. While the bulk of Friday night will be rain free in most areas...a baroclinic zone will become established over the Great Lakes region courtesy of a broad storm system over the Upper Lakes and exiting high pressure to our east. In fact...the forecast pops will be a little higher than those advertised by many of the guidance packages. Just cannot trust a warm front...or in this case...the semblance of one. Saturday will be rather unsettled across our region. The aforementioned warm front will press northwards across the region during the first half of the day...then a pre frontal trough will make its way through during the afternoon. Much like the convective environment from Thursday...sfc based instability will be unimpressive to the tune of 500-1000 j/kg while a 45kt low level jet will set the stage for 40-45kts of deep layer shear. This will encourage any convection to become strong to severe...especially inland from the influences of a well established lake breeze off Lk Erie. Have added a little enhanced wording to the package by mentioning gusty winds with the likely convection. Also like Thursday...it will be warm and humid ahead of the pre frontal trough and subsequent cold front...with max temps of 75 to 80 over the western counties where dew points will also be in the 60s. In the wake of a cold frontal passage...a large sfc high will gradually build across the forecast area during the day Sunday. While this should support fair weather to end the weekend...there is a fairly wide variance in solutions for this period...including the risk that the cold front will stall near or just south of the Southern Tier. This would lend itself to a much more unsettled day if it were to verify. Will compromise for now with low chc pops near the Pennsylvania border. && .LONG TERM /MONDAY THROUGH WEDNESDAY/... A bubble of high pressure will build over the eastern Great Lakes Monday and potentially bring a brief break between rain chances with a mainly dry day. A warm front will move northeast across the eastern Great Lakes Monday night with a chance of a few showers. Tuesday through Wednesday the longwave trough will re-focus across the Northern Plains, forcing downstream height rises across the eastern United States. This will allow warmer and somewhat more humid air to move back into the Ohio Valley and New England. Model guidance has shown some run to run variability with the synoptic scale details during this time period. In a general sense, one or two low pressure systems will move through the Great Lakes later Tuesday through Wednesday. These systems will bring an increase in large scale forcing and a chance of a few showers and thunderstorms at times. High temperatures will move back into the 70s at least, and possibly 80s if some of the warmer model guidance verifies. && .AVIATION /06Z THURSDAY THROUGH MONDAY/... For the 06Z TAFS VFR flight conditions are found across the region, with initial round of shower now to our east. The next round of showers, and potential for stronger thunderstorms will arrive late this morning and afternoon. The early timing of the cold front to the west may limit the amount of thunderstorms across eastern TAF sites, but farther to the east...greater daytime instability may yield thunderstorms for KROC and KART...that may also produce strong wind gusts. Timing for thunderstorms will be between 15Z and 21Z. Behind the storms a cold front will sweep across the region. Wind gusts this afternoon may near 35 or greater knots for KBUF/KIAG and KROC. Cold air advection behind the front will continue breezy westerly winds tonight. Lingering moisture will also lead to the formation of a deck of MVFR range stratus across much of the TAF region by the end of Friday night. Outlook... Friday...VFR. A chance of showers Friday night. Saturday...VFR/MVFR with showers likely and a chance of thunderstorms. Some storms could again produce gusty winds. Sunday...Mainly VFR. Monday...VFR. && .MARINE... High pressure draped across New York State will drift eastward into New England this afternoon...while low pressure advances across Minnesota. In between these two systems a moderate easterly flow will continue across the Lower Great Lakes...though the strongest winds and greatest wave action will remain confined to the open waters of Lake Ontario. Winds will then turn southerly tonight and Thursday morning as a warm front pushes across our region. On Thursday southwesterly winds will increase within the warm sector of a storm system...with winds likely to reach small craft criteria on Lake Erie...and possibly the western half of Lake Ontario. A cold front will then cross the Lower Great Lakes late Thursday and Thursday night...with brisk westerly winds behind this feature leading to the continued possibility of advisory-level conditions on portions of both lakes. && .BUF WATCHES/WARNINGS/ADVISORIES...
