These squalls may contain briefly very heavy snow, strong winds, near white-out conditions, and hazardous travel for the Wed evening commute. - Brief 35 to 55 mph wind gusts possible Wednesday afternoon and evening in most locations and between 50 and 60 mph across the Cape/Islands. - High Wind Watch posted for the Cape and Islands. Wind Advisories may eventually be needed elsewhere. *Bitterly Cold Wind Chills Late Wednesday night into Thursday Morning:* - Wind chills drop to between 10 and 25 below zero late Wednesday night into Thursday morning. - Wind Chill Advisories will likely be needed for a good portion of the region with possible Wind Chill Warnings for portion of the higher terrain of Massachusetts. *Marine Headlines:* - Gale and Storm Watches hoisted for all waters Wednesday afternoon and evening for a period of 40 to 50 knot wind gusts. - Moderate to heavy freezing spray expected Wednesday night into Thursday night across the open waters Please let us know if you have any questions or concerns.

[2019.01.28 AM NWS Briefing] Accumulating Snowfall, Dangerously Cold Wind Chills
by BOX Operations - NOAA Service Account 28 Jan '19

28 Jan '19

Good afternoon, The *WINTER STORM WATCH* continues over northern and western portions of MA with the expected accumulating snowfall for Tuesday afternoon into Wednesday morning. To clarify why we held with the *WATCH*. It is entirely possible the associated storm system could move through faster and we could get less. It is also possible that the heavier precipitation / snowfall outcomes occur outside of MA, more across northern areas of New England. While there is concern of travel impacts outlined below, there is still not a high level of confidence with this forecast. Behind the snows, bitter cold and dangerously low wind chills follow for Wednesday into Thursday. Attached, you'll find the latest headlines and snowfall forecast, along with worst-case and best-case scenarios, for Tuesday afternoon into Wednesday morning along with forecast precipitation types. Also, we've included forecast lowest wind chills for Wednesday through Thursday. Should you have any questions, comments and/or concerns, please don't hesitate to reach out to us. *What / Where / When ...* - Accumulating Snowfall - *Timeline* ... broadly speaking, beginning around noon Tuesday for the CT River Valley, encompassing eastern MA by early evening; becoming moderate, possibly heavy at times over northern / western MA early evening Tuesday to shortly after midnight Wednesday before concluding into early morning Wednesday. - Challenges with respect to the rain / snow transition line, monitoring the Hartford - Worcester - Boston corridor especially. - To get the more finer details we encourage everyone to check out the hourly weather graph for their particular area by clicking on the map in the link below: - https://forecast.weather.gov/gridpoint.php?site=box&TypeDefault=graphical - *Impacts *... slick conditions on untreated roads and hazardous travel, especially for the Tuesday afternoon into evening commute. Watching closely the I-91 corridor throughout CT & MA, as well as the western-halves of I-90 and Route 2. - Dangerously cold wind chills - *Timeline *... developing towards noon Wednesday as Arctic air surges into the region per westerly winds with gusts up to 40 mph; especially Wednesday night into Thursday, dangerously cold wind chills could continue through Friday morning while bitter cold persists into Saturday. - *Impacts *... with greater exposure to the elements, roughly 30 minutes, there is the risk for hypothermia and frostbite. Can't rule out isolated issues with freezing pipes. - *Marine Impacts* ... moderate freezing spray forecast with gales and wave heights up as high as 8 to 12 feet, expect dangerous conditions for all vessels, even those properly equipped for Wednesday through Thursday. *Uncertainty ...* - Biggest challenge is nailing down the exact evolution of the rain / snow line which will ultimately determine snowfall amounts and outcomes. - In addition, there is a measure of uncertainty concerning snowfall amounts, whether meeting or exceeding 3" advisory / 6" warning level criteria for particular counties, hence the continuance of the WATCH. Respectfully, Benjamin Sipprell Meteorologist NWS Boston / Norton If you have any questions or would like more information, don't hesitate to contact us via this email address, on NWSChat <https://nwschat.weather.gov/>, or at the following: National Weather Service Boston/Norton, MA 46 Commerce Way Norton, MA 02766 508.622.3280 Website <http://www.weather.gov/boston> | Facebook <http://www.facebook.com/NWSBoston> | Twitter <http://www.twitter.com/NWSBoston>

[2019.01.27 PM NWS Briefing] Accumulating Snow Late Tue - Wed
by BOX Operations - NOAA Service Account 27 Jan '19

27 Jan '19

Good afternoon everyone, We continue to monitor a low pressure which will bring a period of snow, changing to rain for most, then back to snow late Tuesday into Wednesday. Due to uncertainty in how far inland the change to rain will penetrate, it is still difficult to determine snowfall amounts. We have included a first cut at the best and worst case scenarios, as well as an updated map of our current precipitation type expectations. Have higher confidence in a transition to rain across the eastern half of southern New England. Greater uncertainty with snowfall totals across the interior. We are still not certain how far inland the mixing line will get. *What:* - A storm system, moving along the northeast coast. - Potential for a period of snow, with a risk for total snowfall reaching Winter Storm criteria for some, especially across the western higher terrain. - Low risk for a period of ice and gusty winds. *Where:* - The highest risk for significant snowfall will be across northern and western portions of Massachusetts and Connecticut, with lower amounts toward the southeast coast. - Risk for icing and strongest winds highest across Rhode Island and Southeastern MA. *When:* - Beginning as mainly snow late Tuesday - Potential for a change to ice (with some snow continuing) early Wednesday morning. - Rain may change back to snow with additional accumulations possible Wednesday morning - Mostly done by Wednesday afternoon - Low risk for impact to Tuesday evening commute, higher risk for Wednesday morning commute. *When we will know more:* - We will begin to highlight details over the next 36 hours.
