Storm Coordination Message #1 – Thursday 1/24/18 – Heavy Rain and Strong to Damaging Wind Potential

Hello to all…
..Strong Storm system will bring unusually warm conditions, heavy rainfall and the threat of strong to damaging winds to the region..
..A Flash Flood Watch is now in effect from Thursday Morning through late Thursday Night for the entire NWS Boston/Norton Coverage Area except for the Islands for 1-2″ of rainfall with isolated higher amounts that could lead to urban and poor drainage flooding with the potential for some small river and stream flooding particularly in areas where the heavy rainfall would be combined with snow melt..
..A High Wind Warning is now in effect from 9 AM to 7 PM Thursday for South Coastal Massachusetts including Plymouth County Massachusetts, Cape Cod and the Islands, and South Coastal Rhode Island including Bristol County Rhode Island for sustained winds of 20-30 MPH with gusts between 50-60 MPH. A Wind Advisory is in effect from 9 AM to 5 PM Thursday for Essex, Central and Southeast Middlesex, Suffolk, Norfolk and Northern Bristol Counties of Massachusetts and Providence and Kent Counties of Rhode Island for sustained winds of 15-30 MPH with gusts to 45-55 MPH. These winds will have the potential to cause isolated to scattered pockets of tree and wire damage and isolated to scattered power outages..
..SKYWARN Self-Activation is likely to monitor these threats for Thursday. Ops at NWS Boston/Norton are possible..

A strong but warm storm system will affect the region on Thursday with heavy rainfall and strong to damaging winds. The headlines depict the latest thinking. Key factors for this storm system include:

1.) How much of the extremely strong winds aloft mix to the surface. If temperatures get to around 60 degrees or a fine line of convection forms, it increases the damaging wind threat in the region.

2.) Amount of rainfall over areas recently soaked by the Sunday storm in Southeast New England as well as other parts of Southern New England that have a snow pack from this past Sunday’s winter storm as this will determine the extent of the flooding concerns.

SKYWARN Self-Activation is likely to monitor these threats for Thursday. Ops at NWS Boston/Norton are possible. Another coordination message will be posted by 9 AM Thursday Morning.
