Day 2 Convective Outlook  
NWS Storm Prediction Center Norman OK
1230 AM CST Thu Jan 14 2021

Valid 151200Z - 161200Z


A few thunderstorms are possible over the North Carolina Outer Banks
Friday evening.

...North Carolina Coastal area...

A closed synoptic upper low will be centered over the Midwest
early Friday. This feature will move slowly east through the OH and
TN Valleys during the day. The accompanying occluded surface low
will weaken across the Great Lakes, while secondary cyclogenesis is
forecast near the Mid Atlantic coast Friday night. A front will
initially extend from the occluded low over the Great Lakes, 
southeast through the southern Appalachians into the Gulf Coast
states. The front will continue east and off the Atlantic seaboard
Friday night. Bands of showers will likely occur in vicinity of this
boundary. Moisture return will generally be very limited, but some
models indicate the strengthening low-level jet may advect low to
mid 50s F dewpoints into the NC Outer Banks. A few lightning flashes
might occur as the showers move through the Outer Banks and
intercept greater moisture and a deeper convective layer, but most
thunderstorms will not develop until the this band moves offshore
and over the Gulf Stream.
