Storm Coordination Message #2 – Monday 4/13/20 – Damaging Wind/Severe Thunderstorm/Heavy Rainfall Potential
Hello to all…
..A powerful storm system on Monday will bring the potential for widespread strong to damaging winds, heavy downpours and the potential for isolated to scattered strong to severe thunderstorms for much of Southern New England. This will bear watching given the ongoing COVID-19 crisis response in the region..
..A High Wind Watch remains in effect for the entire NWS Boston/Norton coverage area from Monday Morning to Monday Evening for sustained winds of 25-40 MPH with gusts of 65 MPH and isolated to scattered high wind gusts likely. These winds could cause scattered to numerous trees and wires to come down and scattered to numerous power outages..
..The Storm Prediction Center (SPC) has placed areas from Southeast New York and the New York City area and points south in a marginal to slight risk of severe weather for Monday. This risk area could move further north into portions Southern New England in future updates and will be monitored..
..Heavy downpours and potential thunderstorms are expected to drop 1-2″ of rain across much of the region with isolated amounts of greater than 2″ of rain possible. This could lead to urban and poor drainage flooding in the most flood prone areas. The Weather Prediction Center has placed much of New England in a marginal risk for excessive rainfall..
..SKYWARN Self-Activation with Amateur Radio Call-Up Nets are likely Monday for the strong to damaging winds, strong to severe thunderstorm and excessive rainfall potential..
A powerful storm system is on track to affect the region on Monday and will bring the potential for strong to very damaging winds for much of the region and even another potential round of isolated to scattered strong to severe thunderstorms for portions of Southern New England. The headlines depict the latest thinking. The three main key factors for this storm event are as follows:
1.) The extent of strong to damaging winds and the ability for the winds to reach the surface both ahead of the storm system, in convective showers and downpours and in any strong to severe thunderstorms.
2.) The extent of strong to severe thunderstorm coverage in the region.
3.) Rainfall will be heavy at times but also moving fairly rapidly across the region. Nonetheless, given how heavy the rain could fall in areas of Southern New England, rainfall amounts of 1-2″ with isolated to scattered rainfall amounts of 2″ or more are possible. This could result in urban and poor drainage flooding in parts of the region.
SKYWARN Self-Activation with Amateur Radio Call-Up Nets are likely Monday for the strong to damaging winds and strong to severe thunderstorm and excessive rainfall potential. Another coordination message will be posted by 1030 PM Sunday Evening.
