Accumulating Snow Expected Late Sunday Night Into Monday
by BOX Operations - NOAA Service Account 16 Feb '19

16 Feb '19

Good afternoon everyone. The threat for accumulating snow has increased late Sunday night into Monday, but uncertainty remains in specific amounts. We have included a brief outline in this email. Also, attached is our latest snowfall forecast as well as approximate start and end times. *WHAT: * - Accumulating snow expected. *WHERE: * - All of southern New England. *WHEN: * - Snow is expected to overspread the region from southwest to northeast between 9 pm and 3 am Monday morning. The highest risk for a couple inches of snow accumulation by daybreak Monday will be south of the MA turnpike and especially near the south coast. - The focus for accumulating snow will likely shift to central and eastern MA by Monday afternoon. Snow should wind down from west to east later Monday afternoon into early evening. *POTENTIAL IMPACTS:* - Roads may be snow covered/slippery along with reduced visibility for the Monday morning commute (although more limited given the Holiday). Highest risk will be south of the MA turnpike and especially near the south coast. - Greatest risk for snow and slippery roads during the Monday afternoon/early evening commute will be across central and eastern MA, where the ending time will be the latest. *UNCERTAINTY:* - Latest guidance suggests that 2 to 4 inches of snow appears reasonable for much of the region. These amounts may shift depending on the track of the low pressure system. - A track further south would limit accumulations to mainly an inch or two. If the low pressure system tracks further north, 3 to 7 inches of snow would be possible. Please let us know if you have any questions or concerns.

[2019.02.16 Briefing #1] Accumulating Snow Possible Sunday Night - Monday
by BOX Operations - NOAA Service Account 16 Feb '19

16 Feb '19

Good morning everyone, There is a low to moderate risk of accumulating snow Sunday night into Monday. Here are the details ... *What / Where / When ... * Snow, mainly light is expected Sunday night into Monday across all of MA, RI and CT. *Uncertainty ...* Current indications is for mainly light snow as this weather system weakens as it tracks across the region. The most likely scenario is for snow accumulations to range from a coating to two inches. If the system weakens more rapidly then expected less snow is possible. Conversely, if the system weakens slower as it approaches the region more snow is possible. Three graphics are attached to illustrate these different possible scenarios. This event is still more than 48 hrs away, so changes to the forecast are likely. Thus stay tuned to these updated email weather briefings. *Impacts ... * Despite minor snow accumulations expected, roads may still become snow covered late Sunday night into Monday resulting in slippery travel. With Monday a holiday travel volume may be less than normal, possibly reducing travel impacts. Nevertheless, it doesn't take much snow for slippery travel to develop.
