Good afternoon everyone, Attached is our updated briefing package outlining concerns through Monday morning. *What / Where / When ...* - Lingering winter weather - A mix of freezing drizzle and/or sleet will linger into the early evening hours, as late as 7 pm across the E MA coastline - Additional ice accretion of a trace forecast through that time - Winter weather advisories over RI and Southeast MA through 7 pm - Flash Freeze, Slick Conditions - Flash freeze ongoing along and southeast of the Boston to Providence corridor - Rapid freezing of wet surfaces, standing water - *By evening*, Boston to Providence will be in the teens, S&E in the 20s, Cape & Islands above freezing - *At midnight*, Boston to Providence will be in the single digits, S&E in the teens, Cape & Islands in the low 20s - Bitterly Cold Wind Chills - Bitterly cold wind chills of -15 to -30°F tonight into Monday morning. - Bitter cold will continue through Tuesday morning with wind chills around -10 to -15°F - Wind Chill headlines through Monday - Potential Downed Limbs, Isolated Power Outages - Gusty winds may result in downed limbs and/or isolated power outages across areas N&W of the Hartford to Boston corridor where observed heavier amounts snow and ice remain on trees. - Moderate to Heavy Freezing Spray - Gale Warnings on all waters through Monday morning (may need to be extended as late as Tuesday morning). - Moderate to locally heavy freezing spray later tonight through Monday night - Minor Coastal Flooding - East-coastal MA Monday morning - Isolated pockets of minor flooding along the coast for typically prone locations, especially Boston Harbor south to Cape Cod Bay, as well as northern Nantucket - Mainly due to lingering swell and high astronomical tides *Confidence ...* - High confidence overall, but can't rule out colder temperatures surging in a bit faster by an hour than presently forecast resulting in a quicker freeze across Southern New England. - It's the expectation that as the storm presently passing over SE New England sweeps out to sea that cold air will surge quickly S&E over above-freezing areas of SE New England. Definitely a flash freeze is to be expected no matter what into this evening with all locations below freezing, Nantucket at the latest by 9 pm.
