WHAT HAS CHANGED

As of 130 AM EST Sunday...

No significant changes.

KEY MESSAGES

As of 130 AM EST Sunday...

1. Cold temperatures and a few lingering snow showers for the next few days.

2. Tuesday night through Sunday will feature several chances for light snow showers as our region remains under influence of upper level trough. Best chance for light snow will be late week as a clipper system crosses our area.

DISCUSSION

As of 130 AM EST Sunday...

KEY MESSAGE 1: Large scale troughing will continue to dominate the weather into next week, but there will be no significant storm systems. The nor'easter will stay well to the south and east today. Its only effects will be increased northerly winds and a few high clouds. Light snow showers should continue across the typical higher elevation areas into this morning, but soundings show thinner moisture than yesterday and it looks like they should exit earlier in the day. Any low clouds will cause saturation in the DGZ since it is cold enough to be right above the surface, so any times these clouds are around, flurries will be possible. Due to a relatively stationary pattern, the air was able to wrap around off the Labrador Sea and other parts of the North Atlantic and down into the region from the north. The marine moisture is the culprit for the clouds, and it is easily traced back on satellite. This flow is also causing weak warm air advection from the north, so this moisture and slight warming is helping enhance the clouds, and they are stuck below a subsidence inversion. A few snow flurries have been occurring off Lake Champlain into southern Chittenden and northern Addison counties and this should continue for the rest of the night. It is another indicator that a decent part of the broad lake is still at least somewhat open, though they are much weaker than they are earlier in the season with a lot more lake to work with.

KEY MESSAGE 2: Upper level trough remains over our region and we will have chances for light snow showers from Tuesday night through Thursday as pieces of shortwave energy rotate around base of the trough. Will have some upslope enhancement with northwesterly flow in place as well. For Friday and Saturday expect additional chances for light snow as a clipper system crosses our area. This snowfall will be more widespread, but it's too far out to talk about totals just yet, but clippers generally bring a light snowfall. Models are likely to shift the timing between now and the weekend also.

AVIATION /06Z SUNDAY THROUGH THURSDAY/

Through 06Z Monday...The aviation challenge is areal coverage of clouds and potential intervals of IFR vis/cigs at several sites. Currently have MVFR conditions at EFK, MPV, MSS and SLK mainly due to ceilings, but also have light snow observed at EFK. Some intervals of 2-4SM in BR/HZ likely at MPV/SLK and EFK with less probability of IFR at BTV/MSS and RUT, but its a non zero threat. Any low clouds and reduced vis should slowly improve between 14-16z today with developing northwest winds 5 to 10 knots and increasing high level clouds.

Outlook...

Monday: VFR. NO SIG WX. Monday Night: VFR. NO SIG WX. Tuesday: Mainly VFR, with local MVFR possible. NO SIG WX. Tuesday Night: Mainly MVFR, with areas VFR possible. NO SIG WX. Wednesday: Mainly VFR, with areas MVFR possible. NO SIG WX. Wednesday Night: Mainly VFR, with local MVFR possible. NO SIG WX. Thursday: VFR. NO SIG WX.

EQUIPMENT

NOAA Weather Radio station WXM-44, transmitting from Mt. Ascutney, Vermont, on frequency 162.475 MHz is non- operational at this time. NWS technicians have diagnosed the problem, but repairs will likely not be able to occur for quite some time due to circumstances beyond our control. Therefore, the time of return to service is currently unknown. The following NOAA Weather Radio transmitters may be able to provide service during this outage: WWG 50 from Burke Mtn, VT at 162.425 MHz and WNG 546 from Hanover, NH at 162.525 MHz.

The Colchester Reef meteorological station is out of service. This site is not serviced by the NWS and there isn't an estimated return to service at present. Use extra caution when navigating the broad waters of Lake Champlain. Please contact us if you observe winds significantly deviating from the recreational forecast.
