Marine Weather and Tides
12/16/2019 NOAA is having trouble with requests that include wind gusts. I am posting graphs without wind gusts until it gets fixed.
10/9/2019 Updated the Marine Zones.
9/4/2019 Fixed the weather maps due to NOAA moving them.
7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports.

Area Forecast Discussion National Weather Service Buffalo NY 424 AM EDT Tue Jul 7 2020
SYNOPSIS. Heat and humidity will build through the rest of the week, peaking on Thursday and Friday. The majority of the time will be dry, although a few widely scattered showers and thunderstorms are possible each afternoon and evening mainly inland from the lakes. A weak cold front will arrive Saturday and bring a better chance of showers and thunderstorms, and will also bring somewhat cooler temperatures to the region by Sunday.
NEAR TERM /THROUGH WEDNESDAY/. A gradual increase in low level moisture combined with radiational cooling will allow river valley fog to expand across the Southern Tier through daybreak. The fog will then burn off mid morning. Otherwise the rest of the area will be mainly clear early this morning with just a few patches of high/thin cirrus.
The strong and sprawling ridge over the Midwest will build a little farther northeast into the eastern Great Lakes today. Associated warm mid level temps and poor lapse rates will keep the vast majority of the area dry. A very weak/subtle mid level shortwave will move into Central NY later this afternoon, and this may support a few isolated showers and storms from the western Finger Lakes to points southeast and east of Lake Ontario. Coverage will remain very sparse if anything does develop.
Another convectively enhanced vorticity maxima will move into NW PA this evening. This may support a few scattered showers and storms across the western Southern Tier this evening. Otherwise the rest of the area will stay dry through the evening and early overnight.
Late tonight and Wednesday morning another weak shortwave trough will cross the eastern Great Lakes. This feature will bring some increase in clouds late tonight through Wednesday morning for much of the area, and possibly a few showers. Model guidance continues to suggest the best chance of showers with this feature will be Wednesday morning across the North Country where forcing is a little stronger. The shortwave will move into eastern NY and New England later in the afternoon. A few more widely scattered showers and storms may develop from the Southern Tier to areas east and southeast of Lake Ontario in the early afternoon before ending late afternoon as subsidence increases behind the departing trough.
Heat will continue today and Wednesday, with humidity also slowly increasing. There is still some dry air aloft today, so dewpoints may mix out some in the afternoon. By Wednesday dewpoints will be into the upper 60s areawide. Highs today and Wednesday will reach the lower 90s across the lower elevations of the lake plains away from the immediate lakeshores, with mid to upper 80s across the higher elevations. The heat index will peak in the mid 90s across the lake plain counties this afternoon and again Wednesday afternoon. A few localized upper 90s heat index readings are likely in narrow bands 5-10 miles inland from the lakeshores where surface dewpoint pooling on the inland side of lake breeze boundaries occurs.
SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY NIGHT/. . Heat and humidity will peak Thursday and then continue into Friday with heat indices topping out in the 95F-100F degree range both days .
Wednesday night, any lingering convection will quickly die shortly after sunset and then this will likely be the last of less muggy nights. With that said, in no ways will it be a comfortable without the AC. The only relief will be found well inland where lows may briefly fall back into the low to mid 60s. Elsewhere, lows will be in the mid to upper 60s near 70F along the lake plains.
Surface high pressure and building heights aloft will likely provide a largely dry day across the eastern Great Lakes Thursday. Any convection under this ridge will be limited to well inland across the western Southern Tier and likely focus on ill defined convergent boundaries. Even this will be a stretch, as BUFKIT profile soundings show a fairly strong mid level cap present. Otherwise, the main story will be the heat and humidity as H850T hover in the +19C to +21C range, with highs will topping out in the 90s. This will send heat indices into the 95F-100F degree range. Therefore, Heat Advisories will remain in effect across the Lake Plains and into the Finger Lakes region.
Muggy and mild conditions will follow for Thursday night with lows in the mid 70s along the lake plains. Not much relief will be found across interior locations with lows found in the upper 60s near 70F by daybreak.
Friday, near repeat of Thursday with little change in terms of heat and humidity. It may be a degree or two cooler but it won't feel that way. The only change will be a tad bit more coverage in terms of showers and thunderstorms which will likely add a bit more cloud coverage over the region. Additionally, any storms that do form will have the potential to produce very heavy downpours and move very slowly. Otherwise, with the added cloud cover this may be just enough to nudge highs down a degree or so but highs will still be found in the 90s with indices in the 95F-100F degree range.
Friday night, another muggy and mild night is on tap with increasing chances of showers and thunderstorms as we head into the weekend. Otherwise, lows will again be similar to the previous night with upper 60s to lower 70s across the region.
LONG TERM /SATURDAY THROUGH MONDAY/. Mid-level trough and complex coastal system will combine to bring bring some relief from the heat and humidity over the weekend. It will also lead to increasing chances for showers and thunderstorms which will be welcomed as the ground has become parched across many locations. In terms of temperatures, highs will fall back near or remain slightly above normal with upper 70s to low 80s.
AVIATION /09Z TUESDAY THROUGH SATURDAY/. River valley fog will continue to expand across the western Southern Tier through daybreak with areas of IFR. Some of this will likely impact KJHW for a few hours around daybreak. The valley fog will dissipate by mid morning. A few isolated showers and thunderstorms may develop this afternoon mainly across the western Southern Tier and points east and southeast of Lake Ontario. Coverage will be very sparse, with VFR prevailing in most areas.
Another batch of scattered showers and storms may cross the western Southern Tier this evening with local/brief MVFR to IFR conditions. A weak trough will then approach toward daybreak Wednesday with increasing clouds and isolated showers possible across much of the region.
Wednesday through Friday . Mainly VFR. Widely scattered showers and storms each afternoon mainly inland from the lakes with local/brief flight restrictions. Late night/early morning Southern Tier Valley fog with local IFR.
Saturday . VFR/MVFR. Showers and thunderstorms likely.
MARINE. Relatively light winds will continue on Lakes Erie and Ontario through the rest of the week with a weak pressure gradient in place. Winds will generally be under 12 knots and waves under 2 feet.
CLIMATE. There will be an extended period of hot weather which has the potential to break some records. Some daily records will be within reach over the next several days. Also, the longest streak of 90-degree days in Buffalo may be in jeopardy. Buffalo has already hit 90 today, making it 4 days and counting. Here are the current records .
