Possible tornadoes spawned today in eastern North Carolina as thunderstorms formed ahead of a weak cold front. At the time of this writing multiple reports of hail varying in size from .75″ to 2.75″ and two reports of a funnel / possible tornado were received.
For fun I have saved two animations of our HAMrad II radar product. The first is an animation of BREF (base reflectivity) only to give you a general overview of storm formation. The second includes overlays above the bref product of watches / warnings, and storm report locations. I always find it fun to view the timing of warning issuances based upon thunderstorm intensification, and the placement / timing of storm reports as both are plotted real-time and overlain onto our radar product.
A few samples of storm reports are below:
|2110||MARTIN||NC||POSSIBLE TORNADO (MHX)|
|2140||BEAUFORT||NC||FUNNEL CLOUD REPORTED (MHX)|
|Time (z)||Size (inches)||County||State||Comments|
