Good afternoon.
A Winter Weather Advisory continues for western and central MA, as well as northern CT and into northwest RI early Sunday morning into midday. This is for 1 to 3 inches of snow and sleet followed by a brief period of light icing. The expected onset time of the snow/sleet, along with the latest snowfall and ice accretion forecasts have been attached to this email.
WHAT IS NEW:
- Most of the forecast continues unchanged.
- Time of snow onset is an hour later.
- Snow amounts were reduced a little, based on later start time compared to sunrise.
WHAT/WHERE:
- 1 to 3 inches of snow and sleet expected near and northwest of the Boston to Providence corridor. Greatest risk for the higher snow amounts will be in western MA.
- A period of light freezing rain anticipated across interior MA/CT and into northwest RI. Ice accretion amounts will be light, generally a trace to no more than a tenth of an inch.
WHEN:
- Snow and sleet develop from west to east between 5 and 10 am Sunday morning. A brief burst of heavy snow is possible which may result in roads quickly becoming snow covered, especially in western/central MA into northern CT.
- Precipitation will change to rain by Sunday afternoon along and southeast of the Boston to Providence corridor. Northwest of that region, a period of light freezing rain is expected which should gradually change to all rain by mid afternoon.
IMPACTS:
- Roads may quickly become snow covered Sunday morning with a brief burst of moderate to heavy snow possible. This may also result in a period of poor visibility.
- Conditions should improve in most locations by early Sunday afternoon, but some icy spots may remain possible across the highest terrain of MA
- In areas that have the change to rain, roads with snow/ice-covered drains will have ponding of water with potential for hydroplaning or splashing of sidewalks.
- Regardless, snow and sleet will result in slippery travel Sunday morning along with with reduced visibility.
