(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kbuf 221503 afdbuf area forecast discussion national weather service buffalo ny 1103 am edt Thu jun 22 2017 Synopsis Surface high pressure will slide off the east coast today... While allowing a warm front to press into our region from the ohio valley. The warm front will bring a general chance of showers and thunderstorms as it lifts across the area this afternoon and tonight... While also ushering in a much warmer and more humid airmass. Showers and storms will then become more widespread across our area on Friday as tropical moisture surges across our area in advance of an approaching cold front... Which will then cross new york state late Friday and Friday night. In the wake of the front... Cooler and somewhat unsettled weather will follow for this weekend as broad upper level troughing digs across the great lakes. Near term through tonight As of 15z... Regional surface analysis shows surface high pressure draped across the spine of the appalachians... With an elongated warm frontal zone extending all the way from low pressure over manitoba to central lake erie and northwestern pennsylvania. While skies are still mostly sunny across the bulk of our region... Mid and high clouds are beginning to increase across extreme far western new york... Out in advance of a weakening complex of showers and embedded thunderstorms working its way eastward across the central great lakes and southern ontario. Through the rest of the day... The surface warm front will continue to make its way northeastward into our region... With the boundary reaching the lower genesee valley and western finger lakes by late this afternoon or early this evening. This will result in a continued increase in cloud cover from west to east... With the risk for some showers and a few thunderstorms also spreading across the area in a similar manner this afternoon as the remnants of the upstream convection work into our region. The above stated... These should tend to be much more scattered by the time they arrive... As the much drier and more stable airmass currently across our region should take a decided toll on the already weakening mcs as it presses further eastward. Following the warm frontal passage... Much warmer and more humid air will overspread far western new york this afternoon. With some heating... this could result in the development of enough instability to pop a few additional scattered showers and storms late this afternoon early this evening across the southern tier. Should these actually materialize (a factor that remains in considerable question as of this writing)... available instability and shear profiles could be sufficient for a couple of storms capable of producing locally gusty winds in this latter area... something that we'll need to keep an eye out for as we push through the afternoon and early evening hours. Temperature-wise... Continued steady warm air advection across our region will push 850 mb temps up to between +13c and +17c by late this afternoon... which should translate into high temps ranging from the mid and upper 70s across the north country to the lower to mid 80s across much of the area south of lake ontario. Humidity levels will also be on the increase as well... Particularly across far western new york where surface dewpoints will climb into the lower to mid 60s by late this afternoon. Tonight the surface warm front will continue to make steady northward progress... With this feature largely clearing our area by daybreak on Friday. While the bulk of any associated convection should tend to focus along and northward of the advancing front (i.E., across lake ontario... The north country... And saint lawrence valley)... Some additional scattered convection will still be possible across the rest of the area given the continued advection of an increasingly warm and moisture-rich airmass across our region... For which some chance pops remain in play. The increasingly tropical nature of the incoming airmass will also result in a rather uncomfortable night for sleeping... With surface dewpoints surging well into the mid and upper 60s... And overnight lows failing to drop below the upper 60s (higher terrain) to lower 70s (lake plains). Short term Friday through Saturday night Very warm and humid conditons will be in place across western and central ny Friday ahead of an approaching cold front. Expect building instability and an increase of synoptic scale forcing will bring an increasing threat for heavy showers and thunderstorms through the afternoon and evening hours. Southwest flow off the lakes may try to limit convection across the niagara frontier and near watertown, with the greatest coverage likely from the western southern tier into the finger lakes and southern tug hill region. Dewpoints 65-70 degrees will combine with temperatures climbing into the upper 70s to mid 80s will make for very steamy conditions during the day away from any cooling lake breezes or thunderstorm outflows. Concerning severe potential, SBCAPE forecast 1000-3000 j kg (highest east of lake breezes) and 30-35 kts of 0-6km bulk shear could support a risk for strong to severe storms. SPC has included ny within a marginal risk area for severe storms so have added wording for gusty winds to higher thunderstorm pops. Heavy rain is also a concern as GFS forecast pwat reaches 1.75-2 inches just ahead of the |
front supporting heavy downpours with a few storms. Wpc has also included much of ny within a marginal risk area for excessive rainfall. Have added some enhanced wording to higher pops for heavy rain within thunderstorms. Friday night the cold front will sweep east across the area, with showers and thunderstorms ending from northwest to southeast by or shortly after midnight. Cold air advection behind the front will bring in a cooler and drier airmass with partial clearing developing from northwest to southeast overnight. The drier airmass will allow temperatures to fall into the lower 60s on the lake plains and upper 50s across the higher terrain. Saturday, a broad longwave trough will shift over the great lakes brings cooler air aloft over western and central ny. This cool air aloft will steepen low and mid level lapse rates to support diurnal cumulus and a chance for some showers and possibly weak thunderstorms well inland from developing lake shadows. A stiff southwest flow off lake erie will converge with westerly flow over lake ontario supporting the development of a lake breeze convergence zone from niagara county east along the south shore of lake ontario to oswego county. This band of convergence combined with the steep lapse rates may support a few scattered showers and isolated thunderstorms Saturday afternoon. Continued cold air advection will support more comfortable temperatures with highs in the low to mid 70s in most locations and some breezy winds. Any enhanced lake breeze convection Saturday evening will end shortly after sunset leaving partial clearing overnight. Expect the even drier airmass to allow cool low temperatures in the mid 50s on the lake plains and around 50 across the interior southern tier and lewis county. Long term Sunday through Wednesday The longwave trough over the great lakes is forecast to remain in place into at least next Tuesday and possibly even next Wednesday as progression of the upper level flow pattern is stalled by a strong high pressure area over the north atlantic. This pattern will support several days of cooler temperatures will comfortable humidly levels with daytime highs perhaps topping out within a few degrees of the 70 degree mark. The trough axis is starting to look like it may cross western and central ny on Monday which supports higher end chance range pops. Otherwise, cool air aloft within the trough will support a day-to-day threat of showers and possibly low topped thunderstorms mainly inland of lake breezes. These showers and thunderstorms will be further focused by any shortwaves rotating around the mean trough. If this environment can be coupled with a stout shortwave, would not rule out some small-hail producing storms given the lower freezing level heights and steep lapse rates aloft, especially if storms focus along a lake breeze boundary. Aviation 15z Thursday through Monday Mid high clouds will increase across the region through the rest of the day... As a warm front lifts north into the area. While a few scattered showers and thunderstorms will be possible with the arrival of the warm front... Much of the afternoon should feature mainly dry weather andVFR conditions. Showers may linger along the front across lake ontario and the north country overnight, as the front stalls over ontario province. Overall though, conditions should remainVFR, with occasional period of MVFR conditions in -shra -tsra. Increasing advection of deeper moisture into the area late tonight may drive CIGS down to MVFR across higher terrain of the southern tier, however. In addition, a strengthening low level jet aloft may result in llws later tonight, particularly across far western new york. Outlook... Friday...VFR MVFR with widespread showers and thunderstorms. Friday night...VFR MVFR with rain showers and a chance of thunderstorms. Saturday and Sunday... MainlyVFR with a chance of showers and thunderstorms. Monday... MainlyVFR with a chance of showers. Marine High pressure will keep conditions tranquil on the lakes for much of the day, with the exception of southwesterly lake breezes to around 15kts on the northeastern ends of the lakes this afternoon. Southerly winds will freshen tonight as a warm front crosses the region and low pressure develops over the central great lakes. This will largely keep wave action confined to canadian waters however, and the only serious threat for small craft advisory conditions will not be until Friday night, when a cold front crossing the region will bring cooler temperatures and fresh westerly flow that will raise waves above 4-5 feet on the eastern end of lake ontario. The fresh westerly flow and subsequent SCA conditions will likely continue through the weekend, thanks to persistent upper level troughing in place across the region.
