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.

Area Forecast Discussion National Weather Service Burlington VT 547 AM EST Mon Jan 20 2020
SYNOPSIS. Expansive high pressure over the central and eastern US will lead to an extended period of dry and quiet weather. Temperatures will be below normal to start the work week, then gradually warm through the week. The next chance for any real precipitation will be next weekend after the high pressure shifts northeastward and a low pressure system moves to the eastern US.
NEAR TERM /THROUGH TUESDAY/. As of 543 AM EST Monday . Morning satellite imagery shows residual cloud cover tied to the nrn Adirondacks and Green Mtns waning as final upper level shortwave exits to our southeast. Expect continued loss of cloud cover over the next few hours, especially over the northern Adirondacks and northern Green Mtns. Clouds will hang on the longest west of the southern Greens, but on track for the full area to have plenty of sunshine by this afternoon. Updated sky and hourly temp forecast based on observations/satellite, otherwise forecast on track.
Previous discussion . Deep northwesterly flow will continue through Tuesday, allowing for a brief period of below normal temperatures today through Tuesday. Looking upstream, source air over northern Ontario is actually slightly warmer than normal for this time of year, with any real arctic air staying further northeast over northern Quebec. End result for us is that despite the northwesterly flow, we'll escape any extreme cold under this setup. Nonetheless, temperatures will still be chilly with highs today in the low to mid teens and highs tomorrow in the mid teens to low 20s. Tonight will be the coldest night of the stretch, with high pressure ridging in and fresh snowpack on the ground. Have forecast lows tonight generally between 0 and -10 given some persisting weak gradient flow just off the surface, but if winds aloft end up weaker than expected would need to knock down forecast lows a bit more.
Low clouds will decrease this morning, giving way to mostly clear skies through tonight. A shortwave will move through the northwesterly flow Tuesday, but lack of moisture will result in little more than just some increased clouds developing during the day.
SHORT TERM /TUESDAY NIGHT THROUGH WEDNESDAY/. As of 235 AM EST Monday . Generally benign weather expected for Tuesday night into the Wednesday time frame. This morning's guidance has trended a bit further south and west with an upper shortwave trough passage Tuesday night, so I did bring in a few more clouds and maintained slight to very low chances of flurries/light -shsn to higher elevations of the northern mountains accordingly. Otherwise dry weather is expected. Low temperatures to range from 5 to 15 above from the Dacks eastward, and upper teens in the SLV Tuesday night. Then a nice moderation in temperatures to begin on Wednesday with highs climbing into the upper 20s/lower 30s under partial sunshine.
LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/. As of 235 AM EST Monday . Quiet weather then continues for Wednesday night onward into Friday night as high pressure sets up shop across the northeastern CONUS. Dry air and a noticeable subsidence inversion should limit full mixing potential during the daylight hours with a wider than normal diurnal temperature range expected for this period. That said, values continue to moderate with highs in the 30s to locally near 40 on both Thursday and Friday. For lows leaned more toward a somewhat cooler consensus MOS idea which handles nocturnal radiative effects better than national blended guidance. This would suggest single digits/teens Wednesday night and mainly teens Thursday night.
By next weekend chances for precipitation increase once again as low pressure lifts northeast from the Ohio Valley and occludes while secondary low pressure forms along the Mid Atlantic coast and lifts northward. Still quite the differences in timing and thermal profiles among this morning's medium range guidance with the GFS showing a typical faster solution. For now have suggested higher chances for mainly light snows to arrive by later Saturday and continue into Sunday before tapering off Sunday night. Plenty of time to work out the details on this one.
AVIATION /12Z MONDAY THROUGH FRIDAY/. Through 00Z Tuesday . MVFR ceilings will continue for KBTV, KMPV, KSLK, and KRUT through around 10Z, then improve to VFR by late morning. Could see some brief deterioration to IFR ceilings between 06Z and 10Z, particularly at KSLK, but not expecting these lower ceilings to prevail. KPBG and KMSS will be VFR through the night. After 14Z, expect widespread VFR conditions for the remainder of the TAF period as high pressure builds in. Winds will be northerly/northwesterly overnight under 10kts, then back slightly to the west 5-10 kts after 12Z.
Tuesday: VFR. NO SIG WX. Tuesday Night: Mainly VFR, with local MVFR possible. NO SIG WX. Wednesday: Mainly VFR, with local MVFR possible. NO SIG WX. Wednesday Night: VFR. NO SIG WX. Thursday: VFR. NO SIG WX. Thursday Night: VFR. NO SIG WX. Friday: VFR. NO SIG WX.
