Severe Weather Coordination Message #1 – Tuesday 7/3/18 Severe Weather Potential
Hello to all…
..A weak frontal boundary that is more like a wind shift boundary will tap into the intense heat and humidity and bring the potential for isolated to scattered strong to severe thunderstorms between 2-8 PM across interior Southern New England. Strong to damaging winds, hail, frequent lightning and heavy rainfall with urban and poor drainage flooding are the main threats..
..A Heat Advisory is in effect through 8 PM for the entire NWS Boston/Norton Coverage Area except for Cape Cod and the Islands for heat indices in the upper 90s through 104 degrees when factoring in high Dewpoints with air temperature. Use caution with any outdoor activities, drink plenty of liquids and try to cool down as much as possible..
..SKYWARN Self-Activation is likely today to monitor the convective potential. Ops at NWS Boston/Norton are possible if convective potential increases beyond current expectations..
We have had intense heat and humidity for the last several days but no real potential for convection as the atmosphere remained warm at all levels with the lack of a convective trigger. Today will be different across Southern New England particularly away from coastal areas. A weak front which will be more like a wind shift boundary will provide a trigger and just enough cooling in the upper levels of the atmosphere to allow for the instability to be tapped to allow for isolated to scattered strong to severe thunderstorms with strong to damaging winds, hail, frequent lighting and heavy rainfall with urban and poor drainage flooding as the main threats. Weak wind shear values and the triggering mechanism being fairly weak in nature will limit the severe weather potential to an isolated to possibly scattered nature.
SKYWARN Self-Activation is likely today to monitor the convective potential. Ops at NWS Boston/Norton are possible if convective potential increases beyond current expectations. This will be the only coordination message on the Tuesday severe weather potential. A shortened coordination message will be issued if time allows and ops at NWS Boston/Norton are initiated.
