The National Weather Service Forecast Office out of Newport/Morehead City has issued a warning for increasingly hot and humid air mass overspreading the region starting today and peaking on Tuesday.
The combination of heat and humidity will produce heat index values around 105 degrees today (June 13). The heatwave culminates on Tuesday, with record high temperatures around 100, combining with the very humid air mass to produce excessive heat, with heat indices of 110 degrees or higher for much of the area.
A Heat Advisory has been issued for today, with an Excessive Heat Watch for Tuesday.
An extremely unstable atmosphere will accompany the dangerous heat and humidity on Tuesday, and there is a threat for a significant damaging severe thunderstorm sometime in the afternoon to early evening hours.
At this time, the storm prediction center has upgraded the region to a “slight risk” for severe storms, but if confidence increases that this outbreak will indeed occur, later upgrades may be necessary.
Strong damaging winds of 60- to 80-mph, large hail, very heavy downpours with localized flooding, along with very frequent lightning, may all occur if storms develop Tuesday.
