enjoying a clean radar this evening across the four state region
but this will change as we transition into the pre and Post dawn
hours on Saturday with strong to severe thunderstorms likely
across most of the region along with another shot of flash flood
producing rainfall possibly.

Until that time, not seeing much that would support renewed
convective development overnight across most of our region through
the overnight hours. The exception to this is our northwest zones as
subtle forcing overnight should begin increasing after midnight
and especially towards daybreak. For this reason, have lowered
pops to slight chance variety across all but our northwest zones.

Sfc warm front is very subtle tonight but appears to be located
near a Tyler, Texas to El Dorado, Arkansas line. A very slow
northward movement is expected overnight and it should be through
all but our extreme northwest zones by sunrise. Until that time, have
added areas of fog to the grids north of the warm front with some
observing sites showing some patchy dense fog this evening.

Did not make any significant changes to overnight temperatures but
did address the lack of cloud cover across our southern zones with
this area likely filling back in after midnight.

Otherwise, no other changes attm...13.
