As of 153 AM EST Friday...No significant changes have been made to the forecast.

KEY MESSAGES

As of 153 AM EST Friday...

1. Cold temperatures and brisk westerly winds will make for bitterly cold wind chills this morning, with some lingering snow showers gradually tapering off.

2. A weak system will bring precipitation and light snow accumulations to the region late Friday night into Saturday, which may make for slippery travel, especially across southern Vermont.

3. An unseasonably cold and unsettled pattern looks to continue next week with multiple chances for snow, but no system looks overly significant or impactful.

DISCUSSION

As of 153 AM EST Friday...

.KEY MESSAGE 1: Some snow showers continue to linger across the region this morning, with a particularly persistent band across portions of the Champlain Valley. These showers will continue to taper off as the morning progresses, with a relatively dry afternoon expected. Temperatures this morning will be on the cold side, especially after the warmth earlier this week, with temperatures dropping into the single digits and low teens, with some of the colder spots dipping below zero. Apparent temperatures will generally be below zero this morning, generally -5F to -15F, with the summits closer nearing -30F. Be sure to dress appropriately for the cold, especially if you'll be outside this morning.

.KEY MESSAGE 2: A weak system will pass across the region late tonight into tomorrow, bringing chances for precipitation and additional snowfall to the region, as well as slightly warmer temperatures with some warm air advection. Daytime highs on Saturday look to climb into the 30s, which is nearly 10 to 15 degrees warmer than the high temperatures expected today. While a light dusting or so is possible everywhere, southern Vermont and the spine of the Green Mountains will be the most likely to see a few inches of snow. Current guidance currently supports sub-advisory snowfall amounts across the forecast area, with the exception of some of the higher terrain, but we will continue to monitor as we get closer.

.KEY MESSAGE 3: Cool temperatures and unsettled weather will return to the region for next week, with several chances for precipitation possible. A few shortwaves passing across the region will be able to bring some chances for snow across northern New York and the Green Mountains. Guidance supports an impressive period of lake effect snow early next week, primarily to our south, but some higher snow accumulations will be possible across St. Lawrence County and portions of the Adirondacks and the band waffles northward. Unseasonably cold temperatures will be possible this week, especially on Tuesday where daytime highs will only be in the single digits and teens with overnight lows dropping near or below zero got most of the area.

AVIATION /06Z FRIDAY THROUGH TUESDAY/

Through 06Z Saturday...Upper low continues to spin directly over the Champlain Valley allowing for some snow showers to continue in the vicinity of BTV. These showers should sink southward over the next few hours, but could produce MVFR conditions at times through 12Z. RUT is also experiencing these showers with conditions mainly MVFR through 10Z. MSS/SLK could see a few showers as well with backside convergence squeezing out some snow showers 06-12Z. General trend otherwise will be for showers to taper down with VFR anticipated for much of the day time hours. Northwesterly flow pattern will shift southwesterly and become lighter through the forecast period. Main wind related threat will be at SLK where speeds aloft create some LLWS conditions 12-18Z. The next chances of some isolated/scattered showers will come after 00Z for MSS/SLK.

Outlook...

Saturday: Mainly VFR, with areas MVFR possible. Chance SN. Saturday Night: Mainly VFR, with areas MVFR possible. Chance SN. Sunday: Mainly VFR, with local MVFR possible. Slight chance SHSN. Sunday Night: VFR. Slight chance SHSN. Martin Luther King Jr Day: Mainly VFR, with local MVFR possible. Chance SHSN. Monday Night: VFR. Slight chance SHSN. Tuesday: 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.
