[W8MWA] Advisory: Severe Weather Briefing from NWS for July 4

[Jeffrey Fritz]

The following are my notes from this morning’s briefing with Fred McMullen of the NWS Pittsburgh. (The underlining is mine.)

Due to the fact that a number of us have events today and there is potential for severe weather, I am sharing this with all three lists (NC WV Skywarn, W8MWA and K8MCR.) Given the potential severe weather threat today. It will be well worth your time to read the notes.

If severe weather does occur later today, we will activate the North Central West Virginia Skywarn Net. So please be weather aware today and, if possible, take an HT with you to any outdoor events.

================================

Given the threat for severe storms this afternoon and given all the events and activities that are going on, especially with fireworks later this evening across many communities, we'll start off with the heat risk. 

This will be the fourth consecutive day for most of the region to be in the 90s. Today the maximum heat index across will be around 100F to 105F across much of North Central West Virginia outside of the West Virginia mountains. 

Tomorrow and then Monday, the heat indexes fall back into the mid 90s. The temperatures are still going to be warm in the mid to upper 80s, but, the heat indexes won't be in the triple digit values.

As for Severe Weather, we're looking for showers to develop across parts of western Ohio. As they develop, they'll be moving east into North Central West Virginia. So, that is going to have an impact on outdoor picnics and events that are going on across our communities. 

I want to call your attention to the time between 5:00 p.m. and about 10 p.m. This is the time that is greatest risk for severe weather. Wind will be the primary threat, so downed trees and power lines will be an issue with these storms today. There will also be frequent lightning and heavy rain. Those are the categories and the impacts that we're looking for to develop later on today.

Of course, this is right during that time when a lot of the evening events go off with fireworks at dusk between 9 and 10 p.m. By 10 p.m. as we lose the sun the activity will decrease as we go through the late evening hours. 

In summary, if you have outdoor plans today, especially between 3 p.m. and 900 p.m., that's when you need to stay weather aware. And then if you get down trees or power lines from a storm, again, please report them to the National Weather Service in Pittsburgh. 

This concludes the briefing. Hope everyone has a great Fourth of July.
