(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kbuf 231947 afdbuf area forecast discussion national weather service buffalo ny 347 pm edt Thu may 23 2019 Synopsis Scattered to numerous showers and thunderstorms will end from west to east later this afternoon and evening following the passage of a cold front. In the wake of this feature... Cooler and generally dry conditions will then follow for the rest of tonight and Friday... before another low pressure system brings another couple rounds of showers and thunderstorms later Friday night and Saturday. Somewhat unsettled conditions may then linger into Sunday... Before high pressure brings a return to dry weather in time for memorial day. Near term through Friday As of this writing... The prefrontal trough and its area of much weakened convection is pushing into central new york... With just some garden-variety showers and isolated storms found across the north country. These will continue to push east across this particular region over the next few hours. In the wake of the prefrontal trough... Some additional convective redevelopment has (as previously thought) begun to take shape to the southeast of lake erie... Along the southeastern edge of a developing lake shadow. This activity should continue to develop and push eastward across the southern tier and at least interior portions of the finger lakes this afternoon... With the amount of atmospheric recovery in the wake of the prefrontal trough the key to exactly how well developed this activity will get. Should sufficient organization of this take place... The highly sheared environment that is in place will still be supportive of at least a localized severe weather threat across this particular region... With damaging winds the primary concern. Further north across the niagara frontier and lower genesee valley... The aforementioned developing expanding lake shadowing northeast of lake erie should help to preclude much if any real additional severe weather risk. Speaking of which... Those areas within the expanding lake shadowing will also see a short period of windy conditions out ahead of an approaching cold front this afternoon... With wind gusts to 40-45 mph likely. These will peak between the mid and late afternoon hours... Before quickly diminishing through early evening following the passage of the cold front. In the wake of the cold frontal passage... Any convection will quickly come to an end this evening... With cooler and mainly dry weather then following for the remainder of tonight and Friday. The one possible exception to the dry conditions will be found across the north country later tonight and Friday morning... Where lingering cyclonic upslope flow and low level moisture on the backside of low pressure over new england could lead to a few additional spotty light showers. Otherwise a general increase in low level moisture will result in partly cloudy skies this evening giving way to increasing low clouds overnight... Followed by a general west-to-east increase in sunshine on Friday as high pressure and drier air build into our region. With respect to temperatures... Lows tonight will drop back into the lower to mid 50s in the wake of the cold front... With highs on Friday then generally ranging in the mid to upper 60s. Short term Friday night through Sunday night Surface based ridging extending southeast from james bay will consolidate over ny pa and maintain firm control across the lower lakes Friday night. Look for quiet and dry weather across the region with generally clear skies until late as an approaching warm front introduces some mid and high level clouds. Lows by daybreak will range from the upper 40s to lower 50s across the forecast area. Saturday, the surface high just to our southeast will quickly exit the area and off the nj coast during the early morning hours. Meanwhile, weak surface low pressure over ontario canada will track east while lifting its warm front into western ny. Isentropic lift, supported by a 30 knot llj, and copious amounts of moisture being transported northeast into the region (pw values ramping up to near 1.5 inches) will likely lead to increasing chances of showers and thunderstorms Saturday morning. As the warm front continues to lift northeast across the area into the north country, behind the front there maybe a brief lull in storm activity across western ny before the cold front arrives later in the day evening. Again, another round of storms will be possible with the cold front but with the front arriving so late in the day, instability won't be maximized and waning to an extent. So the potential for widespread severe weather at this point will be limited due to the timing of the cold front. Otherwise, with temperatures climbing into the 70s and a moisture laden atmosphere it will likely be a humid day across the region. Saturday night, low pressure over ne. Ontario canada will track further nne into quebec with its trailing cold front slowly pushing south and southeast into pa where it will stall overnight. Meanwhile, a weak wave is forecast to track out of the midwest along this stalled frontal boundary to our south on Sunday. Although, various model guidance packages differ on the positioning of the stalled front and the strength of the wave which is forecast to pass to our south. For now, have kept chance pops in the forecast to account for the uncertainty. Sunday night, sprawling surface ridging over ontario canada will track east with the axis of the ridge positioned over james bay and bisecting western ny. This feature will introduce quiet and dry weather across the forecast area into Monday. Any residual showers or thunderstorm behind the departing wave will quickly end Sunday |
evening with mainly clear skies developing overnight. Lows will fall back mainly into the 50s under mainly clear skies by daybreak Monday. Long term Monday through Thursday Increased ridging will begin on Monday over the eastern third of the country. This will provide mostly rainfree conditions for Monday. As the ridge strengthens over the southeast u.S., a similar scenario to this weeks weather will take shape. The ridge over the southeast u.S. Will cause waves of low pressure to trek northeast out of western half of the country where a trough will be in place. Waves of low pressure will increase the chance for showers and thunderstorms from Tuesday through Thursday across western and north central ny. Ahead of these areas of low pressure warming temperatures on Tuesday and Wednesday will bring highs across the area to the upper 70s to mid 80s. A passing cold front late Wednesday early Thursday will bring slightly below normal temperates to the area with highs in the mid to upper 60s. Aviation 20z Thursday through Tuesday As of 1840z... A prefrontal trough and its attendant convective line has pushed into central new york and weakened considerably since earlier this morning. This will continue translating eastward across the north country over the next few hours. In the wake of the prefrontal trough... Some additional convective redevelopment remains possible this afternoon into early this evening from interior portions of the southern tier northeastward across interior portions of the finger lakes out ahead of the approaching cold front... With this conditional upon sufficient destabilization in the wake of the prefrontal trough. Should this occur... Such convection could be supportive of some locally strong wind gusts to 40-50 knots. Also out ahead of the cold front... A short period of rather windy conditions with gusts to 35 knots or so is expected across the niagara frontier over to rochester... With the winds then quickly diminishing following the passage of the front late this afternoon and this evening. Following the passage of the cold front... Generally dry weather will prevail tonight through Friday... With the possible exception of a few spotty leftover light showers across portions of the north country overnight and Friday morning. Meanwhile... Mainly vfr flight conditions this evening will deteriorate to MVFR later tonight as low level moisture increases across the region... Before gradually improving back toVFR from west to east through the course of Friday. Outlook... Friday night...VFR MVFR with a chance of showers and thunderstorms overnight. Saturday...VFR MVFR with showers likely and a chance of thunderstorms. Some storms could again produce gusty winds. Sunday...VFR MVFR with a chance of showers and thunderstorms. Monday...VFR. Tuesday... MainlyVFR with a chance of showers and thunderstorms. Marine In the wake of a prefrontal trough... Southwest winds will increase to 15 to 25 knots on lake erie and the western half of lake ontario through this afternoon as an area of low pressure deepens and passes to the north of lake ontario. A cold front will then cross the lower great lakes late this afternoon and this evening... With a period of moderately brisk westerly flow and attendant greater wave action following in its wake. Small craft advisories remain in effect to cover all of this... With gradually improving conditions then expected later tonight and Friday as high pressure builds across the lower great lakes. Tides coastal flooding A cold front will cross lake ontario early this evening. Behind this front moderately brisk westerly winds will produce higher waves on lake ontario, with these combining with very high lake levels to bring the likelihood of lakeshore flooding to the shorelines of wayne... Northern cayuga... And oswego counties. Winds and flooding concerns will then diminish on Friday as high pressure builds into the area. Buf watches warnings advisories Ny...
