Early morning temperatures are mostly in the low to middle 60s
across the Midsouth with a few upper 50s in the typically cooler
locations. High clouds blanket the region. Light north winds are
ushering in a drier airmass. Temperatures will likely fall another
2-4 degrees resulting in sunrise temperatures ranging from the
middle 50s to low 60s.

Seasonably cool temperatures may be the highlight of the weather
story over the next week or so. It does not appear we are facing

A broad positively tilted trough will gradually shift to the east
over the next several days...becoming centered over the
Mississippi river valley by Wednesday afternoon. A midlevel
disturbance and associated cold front will track across the
Midsouth late Tuesday into Wednesday. Along and ahead of the
front, rain showers and perhaps a few thunderstorms will return to
the Midsouth. It appears the heaviest rain and thunderstorms will
be to our South and East as a surface low tracks from South
Mississippi across middle Alabama.

The trough will shift over the Carolinas Thursday and a weak
ridge shift in from the West resulting in drier and warmer
conditions Thursday into Friday.

Next weekend, weak Southwest flow will return to the Midsouth. We
may see enhanced pops again late Saturday into Sunday.
