...Synopsis and Discussion...
Large-scale upper troughing and cyclonic flow aloft will continue to
prevail east of the Rockies through the period, while an upper ridge
builds over the West. A cool/stable pattern, with the influence of
surface high pressure over the Southeast and continental
trajectories over the Gulf of Mexico, will limit lightning potential
across the CONUS through tonight. Shallow convection will persist in
lake effect snow bands off Lakes Erie and Ontario, but the
probability for lightning flashes should remain less than 10
percent. Across deep south Texas and vicinity, weak low-level warm
advection along a coastal front near the lower Texas Coast may
eventually lead to an increase in convection offshore, although the
potential for thunderstorms over land is expected to remain low.
