DISCUSSION...

An upper level ridge of high pressure will build over the Mid
South through mid week before shifting northeastward over the
weekend and into early next week.

An overall reduction in convective coverage is anticipated this
week with the highest potential remaining over southern portions
of the forecast area where mid level heights will be lowest.
Temperatures will remain hot with seasonably high humidity levels.
High temperatures will range from the upper 80s to lower 90s with
lows mainly in the upper 60s to lower 70s. The combination of hot
temperatures and humidity will push heat index values to near or
just above 100 degrees through Friday.

The upper ridge will become centered over the Mid West by next
weekend with deep easterly flow becoming established over our
region. This will help to increase moisture and bring slightly
higher chances of showers and thunderstorms areawide.

By early next week, the upper ridge will rebuild over the region
with lower chances for convection and continued very warm and
seasonably humid conditions.
