WHAT HAS CHANGED

As of 111 AM EST Monday...

No significant changes.

KEY MESSAGES

As of 111 AM EST Monday...

1. Seasonably cold stretch through mid-week with occasional chances for snow showers.

2. Wednesday night through Monday 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. Very cold conditions return to the region this weekend.

DISCUSSION

As of 111 AM EST Monday...

KEY MESSAGE 1: Surface high pressure moves overhead for today and tonight before a weak clipper moves through late Tuesday into Wednesday. Today will be a great day to get outside and do wintertime activities due to highs in the 20s, relatively light winds and mostly sunny skies. A low-level inversion looks to transition into a mostly isothermal profile in the low levels, so the mountains won't be much colder than the valleys. This sets up a good radiational cooling night tonight, with temperatures dropping below zero for most places, with the colder hollows dropping into the negative teens. High clouds begin to move in late in the night but they should have little effect on the temperatures. A few snow showers enter northern New York Tuesday afternoon, before reaching Vermont Tuesday night. They look to linger across the typical higher elevations and upslope areas on Wednesday. Overall, very minor accumulations are expected with most areas only seeing a few tenths of an inch. The higher elevations could see up to around an inch.

KEY MESSAGE 2: Upper level trough and shortwave energy passing our region on Wednesday night into Thursday will bring some light snow showers, especially in upslope areas of the northern mountains. A better organized system will cross our area Friday into Saturday, a clipper type low which will bring widespread light snowfall to the area. Being in the longer range, still a lot of model to model and also run to run inconsistencies. Looks like some much colder air will then settle over our region for the weekend, with below normal temperatures once again with possibility of needing cold headlines once again. Will continue to monitor and work out the finer details as we get closer to the end of the week.

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.
