Good morning everyone, Here is a late morning update for the storm expected to impact southern New England later today into late tonight. *What has changed ...* - Looks like we will see the lower end of the snowfall thresholds on the expected snowfall map (see attached). - Looks like it is going to take a bit longer for snowfall to begin. Things should begin approximately 1-2 hours later than previously expected. - Snow overspreading western MA and northern CT around 5 to 6 PM and reaching eastern MA by 6 or 7 PM. Everything else remains on track, but for completion sake here is additional information from the previous email sent out below. *Timing ... * - Bulk of the accumulating snow begins to taper off between 10 pm and 1 am from west to east. *Duration ... * - This is a fast moving system so the snow will be limited to roughly a 3-6 hour window, but will fall moderate to perhaps briefly heavy for a short time. - Here is an approximate timeline of the steadiest snow/precip - * Boston:* 7 pm to midnight,* Worcester to Springfield *6 pm to 11 pm, *Providence* 7 pm to 10 pm,* Hartford* 6 pm to 10 pm. *Impacts ...* - Not a block buster snow event but it will snow moderate to briefly heavy for a 3-6 hour window (times above) with snowfall rates up to an inch per hour possible during this time. - Cold roads will become snow-covered and slippery immediately after the snow commences. Travel will be difficult this evening with poor visibility too, but improvement expected after midnight. *Snow Totals ... * - Most of MA, RI & CT will receive a quick 3 to 7 inches of snow. Higher amounts towards western and northern MA with the lower amounts near the south coast and Cape. - Snow will end as light rain or drizzle towards midnight across RI/SE MA with temps rising above freezing. - Snow may ends as a period of light freezing drizzle across portions of interior MA and CT towards midnight. Little additional impact expected from that with that falling on top of the earlier snow. *Forecast Confidence ... * - High confidence in several inches of snow falling late today and this evening. - High confidence that snow sticks to roadways immediately with cold ground temperatures. - Localized snow banding may result in some locations getting 1 to 2 inches more or less than what is currently expected, but overall this is a rather high confident forecast. An additional email will be sent later this afternoon.
