Hi everyone We just wanted to send out a quick email that confidence is very high in a significant/very difficult Tuesday pm commute. We have attached an hourly loop of the approximate start time of the snow and when it is expected to change to sleet. While uncertainty still exists on how quickly snow changes to sleet, confidence is high in a brief window of 1-2 inch per hour snowfall rates during the Tuesday pm commute. We will send out the full briefing package later today, but just wanted to focus on the high impact expected for Tuesday afternoon commuters. Please let us know if you have any questions or concerns. Thank You Meteorologist: Hayden Frank 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>
