Good Evening from chief meteorologist Tony R Petrarca…..
Storm system across the Ohio River Valley will emerge off the Mid-Atlantic coast and intensify rapidly just to the south of our area Saturday Night. The net result are increasing winds and snow.
Here’s what we know based on new data coming into the Pinpoint Weather Center:
. Weather starts dry Saturday morning
. Snow Rain mix arrives mid to late afternoon, changing to all snow just after dark.
. Heaviest snow from 6PM to around 1AM Sunday (worst of storm )
. Storm will strengthen rapidly once offshore, so winds will increase to 40-50 mph in gusts at coast
. Heaviest bands of snow will set up across southeast Massachusetts. Snow amounts lessen the further west.
. Snowfall rates for a time will reach 1 inch per hour.
. Storm is “progressive” it will not slow down or stall. Snow will end just after midnight.
“WILD CARD” to watch for.
Should the storm intensify closer to the coast, then snow amounts in Rhode Island would need to be raised….at the same time, a storm track that is further offshore means much less snow. The map below is the curent thinking on snow amounts. New data comes into the weather center around 9pm. Check back with me on FOX Providence at 10PM and on channel 12 Eyewitness News at 11pm to see if the snow accumulation forecast needs to be “tweeked”
