(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kbuf 211807 afdbuf area forecast discussion national weather service buffalo ny 207 pm edt Wed aug 21 2019 Synopsis A cold front will push through the region tonight. While this could spark a few more showers or thunderstorms... It will bring an end to a stretch of warm and muggy conditions. We will then experience spectacular weather Thursday through the upcoming weekend with little cloud cover... Comfortable temperatures and low humidity. Near term through Thursday During the remainder of the afternoon... Our forecast area will find itself within an unstable airmass well ahead of an approaching cold front. A well established lake shadow downwind of lake erie will keep the buf metro area and much of the iag frontier free of any rainfall... While there will be the risk for some widely separated showers and storms most elsewhere. Any convection that does fire up before 6 pm will likely do so along and just ahead of a strengthening lake breeze boundary. As of 1730z... This line of enhanced CU stretched from near batavia southwest along the chautauqua ridge to about ripley. As this mesoscale forcing mechanism pushes east... It will encounter sbcapes averaging 1500 j kg. Fortunately bulk shear values will only range from 20 to 25 knots... So there will not be a significant risk for severe weather. Pwat values in the vcnty of 1.5" though could encourage pockets of locally heavy rain... Mainly over the southern tier and finger lakes region. That being said... The coverage for the possible convection should not be nearly as widespread as that from early this morning. Otherwise it will be warm and humid for the rest of the afternoon with 70 degree dew points being accompanied by temperatures that will largely range from the low to mid 80s. A cold front will gradually push to the south across our forecast area tonight. Other than a very modest 30kt low level jet and some convergence near and ahead of this boundary... There really is not much forcing to support widespread pcpn. A strong h25 jet will pass to our north... But it will be in the 'wrong' place to give any additional lift from the upper levels. It is interesting to note though... That most if not all of the guidance packages are grossly under estimating the strength of the ul jet. Aircraft measurements from across minnesota this morning measured winds >160kts with this jet... But upper air soundings have only been able to 'capture' winds of 115 to 120kts. As mentioned though... The position of the jet is more important and this is not favorable for significant weather production. In any case... Will use chc pops for showers and thunderstorms. Thursday will feature improving conditions... As a cooler and notably drier airmass will gradually push across our region in the wake of the overnight cold frontal passage. While a brief shower cannot be ruled out across the southern tier... Dry air advecting south in the mid levels and a developing subsidence inversion should keep any shower activity to a minimum. Otherwise... It will become increasingly comfortable as dew points in the lower 60s during the morning will drop through the 50s during the afternoon. Meanwhile... afternoon highs will be in the low to mid 70s. Short term Thursday night through Saturday night Upper level trough that drops across lower great lakes and northeast conus late this week will still be mainly north and west of the region on Thursday. Though primary cold front sweeps across by late Wednesday night, strongest cold air advection will lag the fropa, not really arriving until Friday. Strong upper jet over 110 kts on leading side of upper trough and another weaker shortwave area of deeper moisture may trigger isolated showers over southern tier during peak heating Thursday afternoon, but otherwise dry weather should prevail though skies will be partly to mostly cloudy. High temperatures will settle into the low to mid 70s, coolest in the southern tier and to east of lake ontario. Most clouds will fade on Thursday night though some clouds will persist closer to eastern lake ontario. With the clearing skies and temperatures falling into into the upper 40s at the coolest, could be valley fog over the southern tier. Cold air advection continues into Friday with h85 temps down to +7c or +8c by daybreak Friday. NW flow across the much warmer temps of lake ontario (averaging 21c at mid lake) will result in a conditionally unstable airmass for lake effect processes. Other than a thin moist layer around 800mb 5-6kft, soundings look dry. There could be just enough over-water instability and low-level convergence for a few showers downstream of southeast lake ontario. Any showers, if they occur, will become disrupted and disorganized by late Friday morning due to daytime heating and strong subsidence. Another day of expanding stratocu clouds with partly to mostly cloudy skies by afternoon. High temps will be in the lower 70s most locations. After clouds clear out Friday evening, clearing skies and cool temps could lead to another night with some valley fog in the southern tier. On Saturday, high pressure will be firmly in control of weather |
across the region. Though ECMWF still looks overdone with depiction of closed off upper low sinking across the mid atlantic, think a weaker secondary shortwave dropping across southern quebec and new england could lead to some isolated showers east of lake ontario. Probably will just see an enhancement to clouds more than anything else, especially with upslope northerly flow developing by that time. High temps on Saturday begin to tick upward, mainly in the mid 70s. Low temps on Saturday night stay seasonably cool with readings in the 50s across the board. Long term Sunday through Tuesday Sunday features dry weather as high pressure persists. The more sluggish ECMWF would result in more clouds, but still thinking it is overplaying the amount of upper level troughing. Temps will rebound further with readings into the medium range guidance begins to diverge with respect to how quickly the ridge slides further east and out to sea... And gives way to the next trough and associated moisture approaching from the west. The gfs remains fastest with this overall scenario and brings increasing chances for convection into our region... While the ECMWF lies on the other side of the guidance envelope and keeps the ridge intact and our region totally dry through Tuesday. Given continuity and a general distrust for the GFS this far out... Will lean toward the latter scenario and keep dry weather in place through Monday... With only very low-end chances for convection returning on Tuesday. Otherwise... The combination of general airmass modification and warm air advection will lead to a slow but steady day-to-day warming trend through this period... With highs in the lower to mid 70s on Saturday climbing back to the upper 70s and lower 80s by Monday. Aviation 18z Wednesday through Monday Vfr conditions will be found across the region this afternoon and evening... Although a developing lake breeze boundary should help to re-ignite some thunderstorms well south and east of buffalo and rochester. Tonight... A cold front will gradually push across the region. While this feature should generate more scattered convection... The vast majority of the area should continue to experienceVFR weather. The exception will be across the southern tier and possibly the north country... Where late night fog and stratus could lead to MVFR to ifr conditions. Thursday will featureVFR weather as high pressure over central canada will gradually build south across the upper great lakes. Outlook... Thursday through Monday... MainlyVFR with nothing more than southern tier valley fog producing local MVFR ifr conditions each morning. Marine A southwesterly flow will be in place across the region this afternoon ahead of a cold front with waves building to 2-4 feet on lake erie. A cold front will swing across the lower lakes this evening and early overnight, with waves and winds increasing within the cold air advection environment. Wnw winds over the shorter fetch of lake erie will build waves 2-3 feet tonight and Thursday, while a longer fetch and slightly stronger wind flow over lake ontario will bring waves up to 5 feet or greater on the southern lake ontario shoreline. Small craft advisories have been issued. Tides coastal flooding A strong cold front will cross the lower great lakes this evening. Strengthening west to northwesterlies in the wake of the front will increase wave action and combine with already high lake levels to produce significant shoreline erosion and flooding late tonight through late Thursday afternoon. A lakeshore flood warning is now in effect for wayne, northern cayuga and oswego counties. Since winds will be more westerly and not as much onshore, the lakeshore flood watch was dropped for niagara, orleans and monroe counties. Buf watches warnings advisories Ny...
