As we look at Sunday, not much change to what has been outlined in previous messages. Wind shear profiles will start off strong but become less favorable in the region, however, cooling aloft will be more significant and that will increase instability parameters and this along with good moisture will allow for more coverage area of thunderstorms than Saturday and this will potentially allow for another round of isolated to scattered strong to severe thunderstorms. The wind threat for Sunday maybe somewhat reduced but the hail threat will be higher and the cold air aloft may also compensate to a degree for the lack of wind shear. Heavy rain for urban and poor drainage flooding and frequent lightning are also likely. The timing of this activity is still in some flux but activity could be in the mid to late morning around 10 AM through the early evening hours of around 600 PM. While all of Southern New England should monitor today’s weather, central and eastern Southern New England have the highest potential for scattered strong to severe thunderstorms today.
SKYWARN Activation with Ops at NWS Boston/Norton will commence by 10 AM Sunday Morning. This will be the last coordination message on Sunday’s severe weather as we shift into operations mode.
