Day 1 Convective Outlook  
NWS Storm Prediction Center Norman OK
1055 PM CST Sun Feb 07 2021

Valid 081200Z - 091200Z


Severe storms are not expected today.

Broad cyclonic upper flow will prevail across the CONUS through the
period. An embedded mid-level impulse will pivot around the
aforementioned cyclonic flow over the south-central to southeast
U.S, inducing northward low-level moisture advection along the
central Gulf Coast and Florida Peninsula through the day and
overnight. The leading edge of more favorable moisture return will
first overspread the Florida Peninsula. Diurnal heating will
encourage the development of a mixed boundary layer and modestly
buoyant troposphere (given relatively poor mid-level lapse rates),
with isolated thunderstorm development expected. During the
overnight hours, as the mid-level impulse traverses the Southeast, a
stronger low-level mass response will result in moistening of the
925-850 mb layer over portions of the Gulf Coast to the Georgia
coastal waters. At these locales, adequate buoyancy and lift should
foster at least isolated thunderstorm development to the end of the
period (12Z Tuesday).
