Hello to all…

..A nocturnal supercell causes Two EF-1 Tornadoes between 230-300 AM Thursday July 26th, One EF-1 Tornado in the East Douglas/Northwest Uxbridge/Southern Northbridge Massachusetts area and the second EF-1 Tornado in Upton, Massachusetts. A combination of SKYWARN Spotter/Amateur Radio Operator, Police/Fire and Emergency Management reports lead to the confirmation of these two tornadoes. Any further damage photos or videos of the storm damage from the two EF-1 Tornadoes is appreciated and credit will be given to the spotter for the reports..

..Another round of Isolated to Scattered Strong to Severe Thunderstorms is likely across Western Massachusetts and Western Connecticut Friday Afternoon into Friday Evening. Strong to damaging winds, hail, frequent lightning and heavy rainfall leading to urban and poor drainage flooding are the main threats. The Storm Prediction Center (SPC) has placed this area in a marginal to slight risk for severe weather..

Any additional photos or videos from the tornado paths will help with the historical record. They can be sent as a reply to this email, via our WX1BOX Facebook or Twitter feeds or via the email address as pics@nsradio.org and credit will be given to the spotter unless otherwise indicated.

Another round of isolated to scattered strong to severe thunderstorms is likely across Western Massachusetts and Western Connecticut Friday Afternoon into Friday Evening. A cold front will approach western New England and there should be sufficient wind shear along with cooling conditions aloft and sufficient heating and destabilization to bring an isolated to scattered strong to severe thunderstorm threat to this area. The timeframe for severe weather is after 2 PM Friday through early evening. Areas of Northern Massachusetts east of the current risk areas should also likely monitor this scenario as depending on timing, strong to severe thunderstorms could move into portions of this area.

SKYWARN Activation with Ops at NWS Boston/Norton will likely commence around 200 PM through Friday Evening. Another coordination message will be posted by 1000 AM Friday. Below is the SPC Day-2 Convective Outlook:
