(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kbuf 172159 afdbuf area forecast discussion national weather service buffalo ny 459 pm est Sat nov 17 2018 Synopsis A weak cold front will drop across the region this evening with some light snow showers, but otherwise dry conditions. Weak low pressure will pass to our south on Sunday bringing some light snow to the southern tier. There will be some light snow showers during the first half of next week, followed by high pressure and cold and dry weather for thanksgiving. Near term through Sunday For the remainder of this afternoon, plentiful low moisture will result in persistent cloud cover and cool temperatures in the mid to upper 30s. A weak cold front will approach from the north and quickly move across the region through this evening. This will result in a brief increase in lake enhanced snow showers with this front, but any snow accumulation will be light. Showers may be mixed with rain at times this afternoon. Drier boundary layer air will build in behind the front late this evening and tonight. This may result in a brief clearing before mid and high clouds spreading in advance of the next system reach the area. Mesoscale guidance suggests a narrow band or cluster of lake effect snow showers may briefly develop southeast of lake ontario late tonight. Localized accumulations of an inch or two cannot be ruled out, but the vast majority of the forecast area will be dry from late evening on. Winds will shift to the southeast Sunday morning so any lingering lake effect snow will move out over the lake. Low temperatures tonight will be in the teens east of lake ontario, and in the low to mid 20s elsewhere. On Sunday a shortwave embedded in a vigourous upper level flow will move across the region. There will be a sharp mid-level thermal gradient across the area, with this shortwave resulting in a period of warm air advection and favorable jet dynamics. Nearly all model guidance shows measurable precipitation across southern areas, with little if any precipitation north of i-90 from buffalo to syracuse. However model agreement and synoptic scale lift supports categorical pops across the western southern tier even if snow accumulation will only be around an inch. Temperatures will remain below normal on Sunday with highs in the lower to mid 30s. Short term Sunday night through Tuesday night A 120kt upper level jet will be moving across the northeast while surface low pressure tracks along a stalled front south of western ny Sunday night. Dry westerly flow will be increasing across the eastern great lakes and light snow will be departing the western southern tier through Sunday evening. Cold, southwest flow will lead to the generation of lake effect showers northeast of the lakes Sunday evening. Due to the incoming dry airmass, snow showers will be scattered and light. Temperatures will fall into the mid to upper 20's Sunday night. The mean flow will slowly become westerly by Monday morning and snow showers will move east of the lakes impacting the southtowns and western southern tier and east of lake ontario. Synoptic moisture will increase from the north as a shortwave trough approaches lake ontario. This will likely keep snow showers east of lake ontario with enhancement on the tug hill into Monday evening. With this being said, subsidence and mid-level dry air will still keep snow showers scattered and lackluster east of lake ontario. Snow showers will end east of lake erie by Monday afternoon. Minor accumulations of up to an inch are expected east of lake ontario, mainly on the tug hill. Areas outside of the lakes will remain dry Monday. Temperatures will reach the mid to upper 30's. A large scale mid-level trough will remain overhead Monday night into Tuesday night. Surface low pressure will track across the northern great lakes reaching lake ontario by Tuesday morning. A cold front will move across the eastern great lakes and snow showers will track across western and north-central ny. Lake enhancement will produce minor accumulations northeast-east of the lakes by Tuesday afternoon. As flow becomes northwest behind the front, snow |
showers will persist southeast of the lakes where minor accumulations are possible into Tuesday night. Cold with temperatures falling into the low 20s to teens east of lake ontario Tuesday night. Long term Wednesday through Saturday Second clipper shortwave and associated cold front expected to cross the area Wednesday. At this stage, only looking at some nuisance snow showers and limited lake effect potential. Even though the potential for accumulating snows look limited, those planning to travel are strongly encouraged to stay up to date on the forecast as it doesn't take much snow to cause travel issues. Secondary thermal trough will filter in for Thursday on the front side of an approaching area of high pressure and will bring 850 mb temperatures back down below -15c, resulting in a very chilly thanksgiving day with high temperatures capping in the 20s and wind chills in the teens or colder at times. The much anticipated warm-up is still on track, but a bit later than in previous forecasts. Warmer temperatures will arrive Friday and Saturday with most locations see highs in the mid to upper 30s Friday, and in the 40s with 50 degrees not out of question for Saturday. Precipitation chances will increase Saturday as a rather deep but short-wavelength trough swings through the great lakes. Aviation 22z Saturday through Thursday Lots of low level moisture is in place, with cloudy skies across the regions. Cloud bases are in the MVFRVFR flight categories at most stations, except across the western southern tier (including kjhw) where there is a mix of ifr MVFR conditions. These conditions will largely remain until after 21z when a weak cold front approaches and brings some light snow showers. However, behind this front the boundary is drier which will result in improving conditions this evening and tonight. A weak area of low pressure will track to our south and bring a general area of light snow to southern areas on Sunday. This is likely to result in ifr conditions from light snow at kjhw. The steady snow should pass south of other TAF sites, with mainlyVFR conditions expected on Sunday. Outlook... Monday through Wednesday...VFR MVFR. Periodic snow showers. Thursday...VFR. Marine Westerly winds will gradually diminish through this evening as surface high pressure builds toward the region. Small craft headlines were extended a few hours for lake erie and western lake ontario, but small craft headlines will be able to be dropped through tonight as winds diminish. A few weak systems may result in a brief increase in winds Monday through Wednesday, but for the most part the first half of the week should be headline free. High pressure will build across the lower great lakes Wednesday night and Thursday. Buf watches warnings advisories Ny... None. Marine...

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. 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. |
