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 Burlington VT 729 AM EDT Mon Jul 13 2020
SYNOPSIS. Upper level trough will provide the focus for scattered showers and thunderstorms today. This feature will linger into Tuesday bringing with it several chances for showers and thunderstorms. Wednesday is shaping up to be the driest day of upcoming week and looks to offer seasonal temperatures as well. Another front crosses the area Thursday into Friday which will bring more chances for precipitation.
NEAR TERM /THROUGH TUESDAY/. As of 725 AM EDT Monday . No significant changes needed to the forecast. Just made a minor tweak to PoPs to reduce coverage this morning across most of VT as showers continue to dissipate. Best chances this morning will be across northeastern NY and northwestern VT. Otherwise, going forecast is in good shape.
Previous Discussion . The main theme for the day will be continued chances for showers and thunderstorms. Convergence along the shores of Lake Ontario coupled with a weak surface low are sparking showers and thunderstorms across our far western NY zones early this morning. These showers/t- storms will slowly propagate eastward through the morning hours with chances for scattered showers mainly across northern NY and northwest VT this morning.
Little changes were made to the thinking for scattered convection this afternoon as a compact shortwave trough moves south out of Canada and a weak surface low passes to our south. Despite good upper level forcing, minimal moisture is associated with this feature which will limit areal coverage of showers and thunderstorms this afternoon. Shear and CAPE profiles across northern NY & VT are not supportive of any development of severe storms. If these areas can destabilize sufficiently, an isolated stronger storm can't be ruled out with the main threat being briefly gusty winds and heavy rainfall.
As instability wanes after sunset the convective threat will diminish. Chances for showers will remain through the overnight hours as upper level trough remains directly overhead. Atlantic moisture will begin wrapping around from the northeast and anticipate areal coverage of showers and thunderstorms to increase on Tuesday. Again, not looking at anything strong or severe as lapse rates and shear are fairly poor. These showers will mainly provide beneficial rainfall to the area, which we desperately need. Generally speaking, most location should see about 0.25-0.40", with locally higher amounts in any convective elements that develop. Temperatures through the period will be comfortable with highs near normal today in the upper 70s/low 80s and below normal Tuesday (mid/upper 70s). Overnight lows remain slightly above average through Tuesday given widespread cloud cover and precipitation expected.
SHORT TERM /TUESDAY NIGHT THROUGH WEDNESDAY NIGHT/. As of 420 AM EDT Monday . Mid-level trough is expected to progress eastward into the Gulf of Maine Tuesday night, allowing any lingering rain showers to end across the North Country by late evening. Light wind conditions could lead to some patchy fog development late. Otherwise, looking at good radiational cooling conditions with lows mainly in the 50s, except locally 60F at BTV. Appears that mid-level ridging will build in from the west for Wednesday and Wednesday night with generally dry conditions expected across VT and nrn NY. With 850mb temperatures of +12 to +13C forecast by 00Z GFS, should support afternoon highs in the upper 70s to lower 80s with mostly sunny conditions expected. Dewpoints will hold at moderate levels, with 2-m dewpoints primarily in the upper 50s/lower 60s.
LONG TERM /THURSDAY THROUGH SUNDAY/. As of 420 AM EDT Monday . Highest precipitation chances during the long-term forecast period arrives late Thursday into Thursday night, in association with a shortwave trough embedded in WSWLY flow. Both the 00Z GFS/ECMWF are consistent with the timing and location of this feature, and associated sfc-850mb warm frontal structure. Have indicated a period of PoPs 50-65% during Thursday night with best low-level WAA and mid- level cyclonic vorticity advection. MUCAPE is limited, but marginal elevated instability is possible given potential 30-40kt LLJ at 3- 5kft level. As such, carried a slight chance of an embedded thunderstorm during the Thursday night period was well. The remainder of the extended forecast period trends very warm and increasingly humid toward next weekend. Appears valley high temperatures will reach the mid 80s on Friday, and then upper 80s to lower 90s for Saturday and Sunday. Large-scale forcing appears weak, so carried just 20-30% PoPs Sat/Sun for isolated diurnally driven convective potential, mainly tied to terrain forcing.
AVIATION /12Z MONDAY THROUGH FRIDAY/. Through 12Z Tuesday . IFR/LIFR fog/ceilings which developed at valley sites overnight will dissipate towards 13z. MVFR ceilings may linger through 15z at KSLK, but after 15z all locations will be VFR through the remainder of the day. Showers and thunderstorm this afternoon will be scattered in nature so have included mention of VCSH/VCTS at all sites. As return Atlanitc moisture moves into the area, MVFR ceilings are possible overnight at all TAF sites outside the northern Champlain Valley. Winds will generally be 5 kt or less through the period.
Tuesday: Mainly VFR, with local MVFR possible. Scattered SHRA, Isolated TSRA. Tuesday Night: Mainly VFR, with local MVFR possible. Slight chance SHRA. Wednesday: Mainly VFR, with local MVFR possible. NO SIG WX. Wednesday Night: Mainly VFR, with local MVFR possible. NO SIG WX. Thursday: VFR. Chance SHRA. Thursday Night: Mainly MVFR, with local IFR possible. Chance SHRA. Friday: Mainly VFR, with areas IFR possible. Chance SHRA, Slight chance TSRA.
