Hello to all…
..Strong Cold front on track to swing through Southern New England late Halloween Night through Friday Morning bringing a period of heavy rainfall and strong to damaging winds to the region..
..A High Wind Warning is now in effect from 11 PM Thursday Night to 8 AM Friday Morning for South Coastal Massachusetts and Rhode Island including Bristol County Rhode Island and Cape Cod and the Islands for sustained winds of 25-35 MPH with gusts to 60 MPH and isolated higher gusts possible. These winds will cause scattered pockets of tree and power line damage and scattered power outages..
..A High Wind Warning is now in effect from 11 PM Thursday Night to 6 AM Friday Morning for North-Central Rhode Island and all of Eastern Massachusetts including the Metro Boston Area, North Shore and Northeast Massachusetts for sustained winds of 25-35 MPH with gusts to 60 MPH and isolated higher gusts possible. These winds will cause scattered pockets of tree and power line damage and scattered power outages..
..A High Wind Warning is now in effect from 9 PM Thursday Night to 4 AM Friday Morning for Hartford and Tolland Counties of Connecticut and Eastern Hampshire and Eastern Hampden Counties of Massachusetts for sustained winds of 25-35 MPH with gusts to 60 MPH and isolated higher gusts possible. These winds will cause scattered pockets of tree and power line damage and scattered power outages..
..A Wind Advisory is in effect from 8 PM Thursday to 12 PM Friday for the remainder of the NWS Norton Coverage Area for sustained winds of 15-30 MPH with gusts to 50 MPH and higher gusts possible. These winds could cause isolated pockets of tree and wire damage and isolated power outages..
..Rainfall is forecast to be a bit less than originally forecast but amounts of 0.25-1.50″ are likely across much of Southern New England. This is unlikely to cause any widespread flooding issues but nuisance localized urban or poor drainage flooding is possible in areas that have the highest rainfall amounts..
..SKYWARN Self-Activation will monitor this storm system..
A strong cold front is on track to sweep through the region overnight into early Friday Morning. It will bring a period of rain with some convective showers and an isolated thunderstorm or two but more importantly the threat for strong to damaging winds across Southern New England. The headlines depict the current thinking on the strength of the winds. Key factors on the strong to damaging wind potential include:
1.) If temperatures are able to reach 70 degrees or slightly higher, this will allow for the strong to damaging winds to reach the surface more readily.
2.) Any convective showers or possible thunderstorms will have the ability to bring stronger winds down to the surface and will be monitored closely overnight.
3.) The strongest and most damaging winds are expected in the overnight period between 12 AM-5 AM though there will be some strong winds before and after this timeframe given the strong wind fields ahead of the front in the warm air and then with the cold air moving in behind the front.
SKYWARN Self-Activation will monitor this storm system. Another coordination message will be posted by 11 PM EDT this Thursday evening if any change to the SKYWARN Activation posture or change in wind headlines occur and time allows for an update.
