(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kbuf 241959 afdbuf area forecast discussion national weather service buffalo ny 359 pm edt Sat aug 24 2019 Synopsis High pressure across southern canada will expand across the great lakes region through Sunday, and slowly move off new england on Monday. There will be some clouds and patchy valley fog each morning, but otherwise this high will provide a dry pattern which will last through Monday night. The next chance of rain along with warmer weather won't return until next Tuesday or Wednesday. Near term through Sunday An upper level low continues to move east toward the new england coast while an amplified ridge moves into the great lakes. Underneath this ridge is a corresponding area of expansive surface high pressure. But, there's also a thin area of moisture trapped near an inversion ~6500' with temperatures near 2c (and near 5c just below that at 850 mb) per latest amdar. This, together with a nne flow over the relatively warm lakes, continues to produce abundant stratocumulus inland from the lakes this afternoon from strong afternoon insolation. With a lowering Sun angle late this afternoon, expect some of this to thin out this evening with a period of clear skies. However, with peak subsidence overnight as the surface high pressure moves overhead, there may be both valley fog and some low stratus cloud formation as well, at least over the higher terrain, which will trap the settling thin but moist airmass. Otherwise, expect a quiet night with persistence low temperatures. A few outliers last night east of lake ontario dipped into the upper 30s, and while this will again be possible tonight, most other areas should be in the 40s (inland) to low 50s (lake plains). Any areas that end up with a low stratus deck may end up with higher than currently forecast lows. Sunday should feature another day with mixed Sun and clouds, but with the low level flow aloft becoming more ese, a little less cloud cover is expected without a lake contribution. However, that strong inversion will still be in place, and with another day of abundant insolation from a dry airmass aloft without any cirrus, expect at least partly cloudy skies for much of the afternoon, although the immediate shorelines will be a battle ground between lake breezes and the ese flow aloft. At least it should be sunny over the lakes. By the end of the day, some cirrus should start to move in from the sw, but it should be rather thin. Meanwhile, temperatures aloft have bottomed out, and will be on the rise for the next 24hrs (and into next week). Thus expect afternoon temperatures to be about 10f higher than persistence - generally in the mid to upper 70s. Short term Sunday night through Tuesday night High pressure will remain nearly stationary across northern new england and the canadian maritimes into early next week. A mid-level ridge will build across the region Sunday night and Monday maintaining dry conditions across the region. The ridge flattens out Monday night and moisture increases ahead of an approaching cold front across the ohio valley. The surface high will be anchored across new england during this time and continue with dry conditions across the region. There will be hesitation as the high departs Tuesday and while the front nears. An initial warm front will bring a few stray showers near lake ontario Tuesday, and a stray lake breeze shower t-storm may develop across the southern tier. Otherwise Tuesday will be dry with a slight uptick in humidity. The main cold front will be on the doorstep of western ny by Wednesday morning. The 12z GFS slowed the progression of the front and since the low is occluding to the northwest, cut back the chance for showers and any thunderstorms |
Tuesday night until late in the night. Temperatures will slowly climb Monday and Tuesday as warm air advection and a southeast flow increases across western and north central ny. High temperatures will be in the upper 70's to low 80's both days however Tuesday will feel more humid with dewpoints climbing into the mid 60's. Low temperatures will also climb with upper 50's Sunday night and Monday night and the low to mid 60's Tuesday night. Long term Wednesday through Saturday Models have come into better agreement with a cold front passing across the region Wednesday, this as a tropical system and its associated upstream ridge move farther out to sea. Instability along the front is marginal for thunder, while a high pwat content to the airmass (pwats near 1.75 inches) and a deepening warm cloud layer may encourage heavy downpours. Behind this front a cooler airmass will flow over the region. Under an upper level trough, steep mid level lapse rates and lingering moisture will allow skies to become mostly cloudy through the afternoon. As the cold air deepens, with 850 hpa temperatures falling into the upper single digits celsius there may be some lake enhanced rain showers later Wednesday night and through Thursday night. Will have low chance pops near the lakes for this activity, as it may not be cold enough unstable enough to encourage a more widespread lake effect rain event. Another weak cold front will cross our region Friday night. Better lift will be found along lake ontario and points eastward. This will return a chance for rain showers to close out the week. Temperatures will not stray much from normal... With highs in the 70s and lows in the mid to upper 50s through this period. Aviation 20z Saturday through Thursday High pressure will build across the great lakes region through tonight, with mainlyVFR flight conditions through the evening. But with a thin but abundant area of moisture trapped below a 6500' inversion settling overnight, some of this may end up as a low stratus deck - ifr or MVFR, possibly focused over the southern tier overnight. Typical valley locations that don't see this should see fog. Vfr conditions will return on Sunday as surface high pressure continues to move slowly to the east. Outlook... Sunday through Monday... MainlyVFR with nothing more than southern tier valley fog producing local ifr conditions each late night and morning. Tuesday through Thursday...VFR with some short periods of MVFR from showers and thunderstorms. Marine Relatively light and variable winds with corresponding light wave action are expected into Monday as surface high pressure moves slowly east across the region.

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. |
