(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kbuf 231801 afdbuf area forecast discussion national weather service buffalo ny 201 pm edt Fri aug 23 2019 Synopsis Most areas should remain dry right through the weekend, although there is the possibility of a brief shower or sprinkle overnight south of lake ontario and into finger lakes. There will also be several more early mornings with typical inland valley fog. The next chance of rain along with warmer weather won't return until next Tuesday or Wednesday. Near term through Saturday A cool airmass continues to head south toward western ny this afternoon with abundant insolation providing lift and stratocumulus formation, with a fairly shallow cloud depth owing to a dry airmass above about 6000'. The coldest portion of the airmass has yet to arrive, so there will be the possibility of a few light showers sprinkles this evening into Saturday morning late this afternoon across the higher terrain finger lakes south of lake ontario. The main surface feature will be a weak trough that will move south across the lower great lakes this evening. This can be traced to the wealth of cloud cover approaching the lower great lakes. The nam nest does a decent job brining a subtle wind shift along with the development of spotty showers as the trough moves south of lake ontario between ~02-04z. Winds will strengthen some and shift to north-northeasterly while 850mb temps drop a couple more degrees, bottoming out around +6c overnight. This is all being forced by a fairly potent shortwave trough rounding the base of the longwave upper trough that will be in place over the region. Despite low level anticyclonic flow and dry air near the surface, there may be just enough lake enhanced moisture instability, that when combined with the potent shortwave trough aloft, to produce a few showers downwind of lake ontario on a north- northeasterly fetch. Any showers would be mainly focused across the higher terrain of the western finger lakes and the interior southern tier. Otherwise, after some clear skies this evening, expect a resurgence of clouds overnight south of lake ontario. Meanwhile, expect another resurgence of the typical valley fog to form where skies remain clear to partly cloudy late tonight. Expect a dry and quite cool night elsewhere. Temperatures will indeed be chilly by latter august standards. Lows will bottom out in the low to mid 40s across the higher terrain, with lower to mid 50s elsewhere. Saturday, the core of the coldest airmass will be overhead and in the process of mixing out. Thus expect another day with inland stratocumulus development with clear or clearing skies over the lakes by afternoon. On a side note, there may be an interesting "reverse" lake band heading wsw toward the eastern side of lake erie by morning. This won't have any impacts for wny, but it's a little unusual to see the models picking this out. Short term Saturday night through Monday night High pressure will reside across southern quebec and northern new england Saturday night. Variable to light southeast winds will occur overnight. Mostly clear skies and calm conditions will likely result in patchy fog across the southern tier. It will be less widespread than the past few nights because of the abundance of dry air across the region. Low temperatures will fall into the low to mid 50's to upper 40's in valley locations across the western southern tier. Surface high pressure remains in control Sunday while a mid-level ridge approaches the eastern great lakes. Mid-level flow turns out of the southeast with 850hpa temperatures climbing to +9-12c which will help temperatures climb closer to normal, mid to upper 70's for late august. Lingering moisture aloft will lead cumulus development through the afternoon. Dry conditions continue Sunday night into Monday. Low temperatures will fall into the low to mid 50's. While dry weather continues into Monday, attention moves to moisture approaching from the ohio valley. Warm air advection will occur through the afternoon as the mid-level ridge moves overhead. There shouldn't be much change in temperatures including dewpoints from Sunday to Monday however cloud cover will start to increase from the southwest Monday afternoon. High temperatures will again be in the upper 70's to possibly 80 across the lake plains. A warm front enters western ny late Monday night and will increase the chance for showers and possibly a thunderstorm early Tuesday morning. Low temperatures will fall into the mid to upper 50's to low 60's. |
Long term Tuesday through Friday Broad longwave trough over central canada will expand across the great lakes and eastern canada. Sfc flow will increase from the ssw into the lower great lakes Tuesday into Wednesday as main sfc low spins over northern ontario toward the southern shore of hudson bay sending a warm front across the lower great lakes into new england. Expect temps to rise above normal with upper 70s to low 80s a good landing point for now. Details remain murky about convection Tuesday with main issue focusing on how expansive convection will be along warm front. Gfs continues to be more aggressive in eastward push of showers and thunderstorms on Tuesday, showing QPF as far east as areas east of lake ontario, while ECMWF and canadian keep most of activity on Tuesday over western ny closer to approaching strong sw-ne oriented upper jet ahead of broad trough and also closer to axis of 1.75 to 2.0 inch pwats. Convective shortwave(s) riding into ny ahead of main trough will have to be watched as it could boost pops earlier, but going to go with slower idea from ECMWF and canadian given strength of incoming trough which will tend to amplify mid-upper level flow and keep most widespread precip closer to larger scale features. As initial cold front moves through Tuesday night into Wednesday, should be a greater chance of seeing widespread convection. Though mid to upper level winds will be brisk from the sw, any convection will have potential to produce heavy rain as pwats reach 2 inches and wbzero heights rise toward 14kft. Though it is pretty far out to hone in on the details, seems that greatest chances for showers and storms on Wednesday will be over our eastern areas toward finger lakes and east of lake ontario as cold front arrives there during the afternoon during peak heating MAX instability. If that timing holds and sufficient instability is present, there would be at least some risk of stronger storms given strong wind fields present. High pressure is then forecast to build across the region later Wednesday into Thursday behind the cold front. This will encourage the return of fair weather along with more comfortable humidity levels. Aviation 18z Friday through Wednesday An inland stratocumulus deck should dissipate this evening, only to be replaced by additionalVFR CIGS overnight as the coldest airmass moves overhead. Lake induced clouds form across areas south off lake ontario this evening, with lowVFR CIGS possible across the genesee valley, finger lakes and southern tier for the second half of tonight. Valley fog will also be possible across the typical valley areas where cloud coverage remains clear to partly cloudy. Saturday should be a another day withVFR, but with more of a N or nne flow aloft. This day will feature another round of inland stratocumulus. Outlook... Saturday night through Monday... MainlyVFR with nothing more than southern tier valley fog producing local ifr conditions each late night and morning. Tuesday and Wednesday... MVFR possible with showers and thunderstorms. Marine Expect some light chop on both lakes this evening before winds briefly freshen out of the north-northeast later tonight through early Saturday morning. This will bring another round of choppy conditions on lake ontario, but again it looks like conditions will stay below small craft advisory criteria. Gradient flow will relax some later Saturday afternoon into Sunday as high pressure builds closer the lakes. This will promote light winds and diminishing waves. Buf watches warnings advisories Ny... None. Marine... None. Synopsis... Jm zaff near term... Jm zaff short term... Hsk long term... Jla aviation... Jm zaff marine... Jm zaff |

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data.

For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program. |
