(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kbuf 200219 afdbuf area forecast discussion national weather service buffalo ny 1019 pm edt Mon aug 19 2019 Synopsis Summery conditions will continue through midweek as high pressure builds into the region for the early part of the week. This will mean generally clear nights and days with abundant sunshine until the approach of a system on Wednesday. This will spread showers and thunderstorms across the region ahead of a cold front that will slice through the area and bring cooler and drier air into the area on the heels of gusty northwest winds the second half of the week. Near term through Tuesday Ir satellite imagery showing just a few scattered clouds left from the south shore of lake ontario into the finger lakes, with clear skies elsewhere. Expect mainly clear skies to prevail overnight across most of the region. The departure of a cold front to the east has allowed for nominally lower dewpoints to begin their spread into the area from the west. This will continue for a few more hours as the apex of a surface high pressure ridge begins to bridge toward the lower great lakes from the middle ohio valley through the evening hours. This will be the main influence over our weather for the next 36 hours or so, which means gradually fading flow over the area and strong inversions forming tonight. As a result, fog formation is almost a foregone conclusion in the river valleys of the southern tier. Based upon river to atmosphere delta t's, this could be locally dense. Lows tonight will drop into the upper 50s to lower 60s in most areas, and even some lower 50s for the north country. High pressure will gradually slink east of the region on Tuesday, which will turn flow from the southwest again. This will allow for warm advection to resume, which will bring temperatures back up into the mid 80s on a widespread basis after fog mix out. Likewise, flow from the southwest will again bring dewpoints back up into the muggy range in the mid to upper 60s by later in the afternoon across western ny. Moisture instability return coupled with daytime heating may allow for a few isolated to widely scattered showers and storms to develop across northern pa in the afternoon, and some of these may spread northward into the western southern tier by late afternoon. Otherwise the rest of the area will remain dry with plenty of sunshine. Short term Tuesday night through Friday night A 'change of seasons' on the horizon... the amplification of the upper level pattern will not only lead to a change in the weather across our region... But it will feel like we've changed seasons. The buckling of the current near zonal flow will come as a result of a strong shortwave that will rotate across british columbia in the hours leading up to this period. This will force an anomalously strong ridge to build over central canada... while a deep but progressive trough will dig over our region. The result of this scenario will be a change from mid july weather to early autumn as temperatures will plunge to below normal levels. As is almost always the case... This transition could be marked by significant weather. The details. High pressure will move off the new england coast Tuesday night... while a strong cold front will approach from the upper great lakes. The deepening southerly flow found between these systems will not only help to hold up our temperatures... But it will also transport increased low level moisture into our region. This could lead to some nuisance showers across the southern tier... Although the bulk of the region will just be warm and muggy with no precipitation. Wednesday will then be quite active across our region. A pre-frontal trough in the morning will combine with an already unstable environment (mlcapes averaging 500 j kg) to encourage an increasing coverage of showers and possible thunderstorms. As we push into the afternoon... A strong cold front will settle to the south across lakes erie and ontario. While there will be a fair amount of cloud cover around... There should be enough insolation to push sbcapes to between 1000-1500 j kg. The increasingly unstable airmass ahead of the approaching front will then combine with the forcing form a modest 30kt low level jet to support widespread showers and thunderstorms... Which should include locally heavy rain and possibly some strong convective wind gusts. Have already raised pops to categorical for the afternoon. The showers and thunderstorms will taper off from north to south early Wednesday night as the cold front pushes into pennsylvania. |
While somewhat drier air will work into the region late... The real airmass change in the wake of the front will be delayed until Thursday. Speaking of which... Thursday will be cooler and much more comfortable as dew points will gradually drop through the 50s. Meanwhile h85 temps falling into the single digits will only support afternoon temperatures in the low to mid 70s. Otherwise the day will feature some 'self destruct sunshine'... As steep lapse rates of 9-10 deg c km beneath a staunch substance inversion will combine with a chilly cyclonic flow to encourage midday and afternoon strato-cu. Despite the low level instability... The vast majority of the region will experience rain free conditions. Will include slgt chc pops away from the lakes with low chc pops found over the north country where an upslope flow and a passing shortwave could allow for a couple showers. Thursday night through Friday night will have an autumnal feel... As overnight mins will range from the mid 50s near the lakes to the 40s in the cooler southern tier valleys and possibly the foothills of the adirondacks. Outside of some lake induced cloud cover southeast of lake ontario late Thursday night... This three period stretch should be mainly clear. Enjoy! Long term Saturday through Monday There is fairly strong consensus between the GEFS and operational ecmwf that general ridging will be found over the region through this period. The resulting fair dry weather will be accompanied by subtle day to day warming... So that near to below normal temperatures at the start of the period will climb above normal by the start of the new work week. Aviation 02z Tuesday through Saturday High pressure will build east across the area tonight, bringing mainly clear to partly cloudy skies overnight. River valley fog will develop across the western southern tier, with local ifr vsby from about 05z-13z. Some of this may impact kjhw. TuesdayVFR will prevail after the valley fog in the southern tier dissipates. Expect diurnal cumulus to develop along and inland of the lake breeze boundaries. Deeper moisture and better instability across pa will drift north into the western southern tier later in the afternoon and may support a few isolated to widely scattered showers and storms with local MVFR to ifr conditions. Outlook... Wednesday...VFR with areas of MVFR ifr in thunderstorms. Some storms may be strong with gusty winds and hail. Thursday through Saturday... MainlyVFR. Marine The west to southwest winds will weaken this evening and become light and variable overnight through most of Tuesday... As high pressure will drift across the region. Choppy wave conditions will settle down later this evening. A cold front will cross the lower great lakes late Wednesday and Wednesday evening. This will generate numerous showers and thunderstorms... With some storms likely producing strong gusty winds. Strengthening northwesterlies in the wake of the cold front will lead to solid small craft advisories for the lake ontario nearshore waters Wednesday night and Thursday. Meanwhile... A shorter fetch and lower wind speeds may allow conditions to remain below small craft advisory criteria on lake erie. Tides coastal flooding A strong cold front will cross the lower great lakes late Wednesday and Wednesday evening. Strengthening northwesterlies in the wake of the front may combine with increased wave action and already high lake levels to produce more significant shoreline erosion and flooding Wednesday night into Thursday evening. A lakeshore flood watch has been issued from niagara county to oswego county to address this increased risk. Buf watches warnings advisories Ny... Lakeshore flood watch from Wednesday evening through Thursday evening for nyz004>006. Lakeshore flood watch from Wednesday evening through Thursday afternoon for nyz001>003. Marine... None.
