Day 1 Convective Outlook  
NWS Storm Prediction Center Norman OK

Valid 051630Z - 061200Z


Severe thunderstorms are not expected across the U.S. mainland today
or tonight.


A few thunderstorms remain possible mainly near the TX coast as a
series of weak impulses move northeast along southeastern periphery
of an upper low situated over northern Mexico. Very sparse lightning
flashes also cannot be ruled out farther west toward central through
northwest TX from mid-level convection. Here, steeper 700-500 mb
lapse rates exist in the presence of strong mid-level ascent
associated with vorticity maxima rotating through the upper low
