Area Discussion for - Buffalo, NY
(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kbuf 241455 afdbuf area forecast discussion national weather service buffalo ny 1055 am edt Fri may 24 2019 Synopsis Cool and generally quiet conditions will continue over the area as high pressure advances eastward through tonight. Conditions will then deteriorate late tonight through Saturday night due to a pair of frontal systems which will push through the region. High pressure will then ridge southward from canada and into the great lakes providing mainly dry weather for Sunday and Monday. Near term through Saturday Cyclonic northwesterly flow continues to dominate the forecast area late this morning with remnant upslope shower activity still plaguing especially lewis county. As the afternoon ensues, low convective temperatures will likely preclude much in the wave of progressive clearing even with the system to our east departing, however its departure may be enough to counteract low convective temperatures in terms of additional cloud expansion. Thus, the status quo was generally held in skies for the afternoon with a fairly wide range in temperatures dependent upon the amount of insolation through the day... With the western portions of the area away from water decidedly warmer than the eastern portions. Going into the evening and overnight hours, the remnants of the mcs over ia and wi this morning will make a futile attempt to crest the ridge sprawling through the great lakes. Hi-res model solutions really eviscerate this MCS as it attempts to do this, while the larger scale models hang onto some semblance of narrow lifting on the front side of the circulation associated with the decaying remnant mesolow. Low end pops were still maintained across wny and the western southern tier for this during the evening hours before dry conditions resume. The mid-level ridge axis passes east of the CWA on Saturday morning, allowing for flow to rapidly become southerly and then southwesterly across the area with a warm front advancing through the cwa. This will bring much more humid conditions into the CWA as evidenced by pwat values jumping progressively through the day toward 1.75 inches. With the warm frontal passage, the deepest moisture and corridor of favored ascent with a leading short wave looks to be just to the north of the area with weaker moisture and shear fields farther south. Thus, the best chances of precipitation from the warm frontal passage looks to be just to our north, however things look to get a bit more interesting once we are entrenched in the warm sector by the afternoon. With the aforementioned soupy 1.75 inch pwat environment sprawled across most of new york state by Saturday afternoon, and MUCAPE values vaulting toward 1000-1200 j kg, especially over the southern tier, with 0-6 km bulk shear values on the order of 35 kts, convective development seems a fairly good bet. Activity seems likely to kick off fairly early with additional redevelopment as the mesoscale environment plays out in terms outflow interactions. That said, hi-res guidance is going absolutely loopy in the warm sector. However, given that the best shear doesn't start to arrive until very late in the day or into the evening, and the apex of warm air doesn't get to our area until this juncture, it would seem the best potential for anything severe would hold off until then. That said, SPC does have the area west of i-390 in a slight risk, and it would seem the time period closer to the evening on Saturday would be the window for this. Further, it would seem heavy rain would be more problematic, anyway. Deep moisture, weakened afternoon shear, and the potential for successive rounds of convective activity will yield potential for heavy rain accumulations. This could lead to localized flooding. Short term Saturday night through Sunday night Sunday a weak frontal boundary will drop southward across the region. We will still be on the humid side to start the day and a few showers or thunderstorms remain possible through the |
afternoon as we'll remain unstable. This precipitation will end through Sunday early evening as moisture depletes as surface high pressure over canada funnels drier air southward. Skies will clear through the night with overnight temperatures dropping back into the lower 50s. Long term Monday through Thursday Increased ridging will begin on Monday over the eastern third of the country. This will provide rainfree conditions for Monday, with comfortable levels of humidity as surface high pressure to the north pushes drier air southward. 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 15z Friday through Tuesday A closed low will settle across maine this morning which will increase moisture and result in cloud cover and lower cigs through the morning hours. This will result in areas of MVFR clouds, especially east of lake ontario but also south of lake ontario where these clouds will be more patchy in nature. Cloud bases will lift late this morning, and eventually scatter out this afternoon and evening with widespreadVFR flight conditions. A warm front will approach from the southwest late tonight. This will result in an area of low to mid level clouds and possibly a shower or thunderstorm west of rochester near daybreak Saturday. Outlook... Saturday...VFR MVFR with showers likely and a chance of thunderstorms. Some storms could 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 Winds have picked up behind a cold front, which will support small craft advisory conditions this morning, particularly along the southeastern shores of lake ontario. Winds will then subside this afternoon as high pressure will push east from the upper great lakes. Generally light winds and negligible waves can then be anticipated tonight and Saturday. Tides coastal flooding A cold front has moved across the area with westerly winds producing higher waves, especially across the eastern half of lake ontario. This combined with very high lake levels will result in flooding along the shorelines of wayne... Northern cayuga... And oswego counties. Winds and waves will diminish by this afternoon which will lower the flooding concerns. Buf watches warnings advisories Ny... None. Marine... None. Synopsis... Fries near term... Fries short term...
