Severe Weather Coordination Message #2 – Wednesday 8/21/19 Severe Weather Potential
Hello to all…
..Isolated to Scattered Strong to Severe Thunderstorms are likely this Wednesday Afternoon and Evening, 8/21/19, across much of Southern New England particularly along and north of the Boston to Providence line. Strong to damaging winds, hail, frequent lightning and heavy rainfall leading to urban and poor drainage flooding to flash flooding are the main threats with the main timeframe between 2-9 PM EDT Wednesday..
..The Storm Prediction Center (SPC) has placed all of Southern New England in a slight risk for severe weather which is a slight expansion in the risk area since last night..
..SKYWARN Activation with Ops at NWS Boston/Norton will commence by 2 PM EDT Wednesday to monitor severe weather potential..
A warm front is pushing its way through Southern New England this morning. There has been some cloud cover and some showers and thunderstorms with this warm front but satellite imagery and radar indicates clearing behind this activity. The severe weather with this late morning/early afternoon activity is low but an isolated strong to severe thunderstorm is possible with this activity. Most models continue to take this warm front through the area through early afternoon with clearing behind it setting the stage for a favorable environment for severe weather potential across the region with sufficient wind shear profiles and significant heating for destabilization and high instability with a trigger in an approaching cold front. The potential for a reasonable amount of strong to severe thunderstorms is likely though we will continue to monitor how active the warm front is and how quickly the cloud cover moves out of the area. The timeframe for increased coverage of strong to severe thunderstorm activity after the original activity is after 2-3 PM this afternoon through about 9 PM EDT this Wednesday Evening. The headlines of the message depict the current thinking.
SKYWARN Activation with Ops at NWS Boston/Norton will commence by 2 PM EDT Wednesday to monitor severe weather potential. This will be the final coordination message as we move into Amateur Radio Ops mode.
