| Area Forecast Discussion National Weather Service Caribou ME 728pm EST Wednesday Jan 21 2026 .WHAT HAS CHANGED... -Updated aviation discussion. -Increased confidence for snow squalls Thursday and Friday. -Issued a Gale Watch for the Coastal Waters Thursdaypm through Friday AM. -An Extreme Cold Watch has been issued Friday night into Saturday morning. -Low chance of a winter storm Sunday night into Monday. .KEY MESSAGES... - Light snow tonight into Thursdayam to make for slippery travel for Thursdayam commute. - Snow squalls possible Thursday and likely on Friday. - Frigid arctic air brings extremely dangerous wind chills this weekend. - Low chance of a winter storm Sunday night into Monday with the greatest threat to southern areas. KEY MESSAGE 1...Light snow tonight into Thursdayam to make for slippery travel for Thursdayam commute. KEY MESSAGE 1 DESCRIPTION... A weak low pressure system will track across the CWA (County Warning Area) tonight into Thursdayam along a triple point associated with the larger system in Quebec. Expecting an area of light snow to develop tonight across much of the southern 1/2 of the CWA and across portions of Northeast Aroostook county. Steady snow will taper in the morning hours. Expecting 2-4 inches across the Bangor Region, Southern Aroostook to the Downeast coast with 1-3 inches north of there in Aroostook closer to the border with New Brunswick. The least amount of snow expected in the North s where a Dusting to 1 inch is possible and this includes the Moosehead region. This is expected to make things a little slippery overnight but much of the snow will be light and fluffy and given the cold ground expecting no significant travel impacts. KEY MESSAGE 2...Snow squalls possible Thursday and likely on Friday. KEY MESSAGE 2 DESCRIPTION... A ton of uncertainty on Thursday on the likelihood of heavy snow showers or potentially squalls. A weaker surface cold front will push through the area in the afternoon into the evening. Significant uncertainty lies in how unstable the atmosphere will be in the afternoon. Much of the morning will be overcast and the front strength is questionable. Hi-Res CAMs this afternoon are showing a little bit steeper lapse rates, the RRFS/NAM3km/HRRR, while the globals still struggling on how unstable the boundary layer will be. For now did raise POPs higher than NBM and blended in much of the CAMs to focus the greatest heavy snow shower and squall risk to the north. Additional uncertainty lies in how much wind can mix down as much of the modeled soundings show 25-30kt available in the globals with hi-res showing 25-40kt. The BTV snow squall parameter has significantly jumped up significantly with the latest hi-res models while remaining 1-2 with the global models. Have messaged in social media and HWO about the threats of heavy snow showers and squalls. The greatest threat for snow squalls will be on Friday as an arctic cold front passes through the region during the afternoon. Snow squalls may begin in the North s around mid-day before spreading east through the early evening. Currently expecting the greatest chance for snow squalls to be in the Central Highlands, North s, and Aroostook county as model soundings show this is where the greatest instability will be. Still, some strong snow showers and possibly a snow squall or two are possible further south. Currently expecting this to be one of the higher end snow squall events of the winter so far as models show ample instability exceeding 100 J/kg in some northern areas, sufficient lift from a cold front, decent moisture, and a deep mixed layer up to about 650mb with winds in excess of 30 mph that could easily be mixed down to the surface. KEY MESSAGE 3...Frigid arctic air brings extremely dangerous wind chills this weekend. KEY MESSAGE 3 DESCRIPTION... Behind the cold front exiting to the east late Friday, arctic air will get funneled into the region through this weekend. The cold is expected to persist through Monday before beginning a warming trend early next week. The coldest temperatures are expected Saturday night into Sunday morning where lows may dip to near -20 in the north and near -10 further south. Some areas could even get colder if winds stay light and skies remain clear. However, the period of greatest wind chills is expected Friday night into Saturday morning, reaching as low as -40 in northern Maine and -25 further south. This is due to a pressure gradient persisting over the area Friday night as low pressure departs over the maritimes and high pressure builds in from the west. Temperatures will warm slightly during the day on Saturday but will still be very cold, possibly not getting above 0 in the north, and winds will remain elevated resulting in wind chills as low as - 25 degrees. Slightly warmer Sunday with temperatures in the single digits and lighter winds. Remember that exposure to these frigid temperatures can quickly result in frostbite and hypothermia. KEY MESSAGE 4...Low chance of a winter storm Sunday night into Monday with the greatest threat to southern areas. KEY MESSAGE 4 DESCRIPTION... Global deterministic models and their ensembles are showing a low potential for a winter storm beginning Sunday night as low pressure initially positioned in the mid-Atlantic region redevelops offshore and moves northeast off the New England coast. Ensembles emphasize there is considerable uncertainty in when and if such a storm reaches us. A large margin of members keep the system well offshore but some bring it into the Gulf of Maine resulting in accumulating snowfall, especially in the Bangor and Downeast regions. The overall evolution of the system will be dependent on how persistent high pressure is over us on Sunday as a stronger high will keep the storm further from our area. Marine Small Craft Advisory in effect for the Intra-Coastal Waters through 7PM Friday. Small Craft Advisory for the Coastal Waters until 1PM Thursday then a Gale Watch from 1PM Thursday through 7AM Friday. For the SCA (Small Craft Advisory) SW winds 15-25kt with a few gusts up to 35kt and seas 6-9ft. For the Gale Watch, W winds 20-30kt with gusts up to 45kt and seas 7-10ft. Friday through Monday Gales Friday with the peak winds Friday night before decreasing below gale criteria Saturday night and below small craft criteria by Sunday morning. Winds increase above small craft criteria Sunday night into Monday. Seas peak at 6 to 10 ft Friday night and decrease to 2 to 4 ft by Sunday morning. Moderate to heavy freezing spray Friday night through Sunday.
