hot conditions to continue as upper-level ridging holds areawide.
High temperatures this afternoon in the middle to upper 90s closing
in on 100 degrees across some locations at this time. A heat
advisory remains in effect for much of the region with expected
afternoon heat index values to range from 105 to 110 degrees in
the advisory area.

Heat advisory re-issued for Wednesday across portions of southern
Arkansas and north Louisiana. Weak disturbance in the northern
Gulf of Mexico to allow for a slight chance of convection across
southern and eastern zones during the afternoon.

Could see chance of showers and thunderstorms across entire area
on Thursday with isolated convection on Friday as atmosphere
destabilizes with upper-ridge shifting west and surface boundary
lingering across northern Gulf Coast.

High temperatures to be slightly cooler on Friday and Saturday. However...
afternoon high temperatures to again approach 100 degrees late in
the weekend and into next week as upper-ridge strengthens across
