Area forecast discussion, Aug 22, 2:36 PM CDT, 41 minutes before
Area Forecast Discussion
National Weather Service Little Rock AR
236 PM CDT Sun Aug 22 2021

.SHORT TERM...Tonight Through Tuesday

A heat advisory is in effect until 8pm this evening, with heat
index values between 105 and 110 forecast across central and
southern AR. An upper ridge will persist across the southern US
over the next several days, allowing temperatures to continue to
climb. Heat index values will climb Monday afternoon and the heat
advisory (heat index values 105-110) will be expanded to include
the entire forecast area, with an excessive heat warning (heat
index values 110+) for the southeast corner of the state. Low
temperatures are forecast in the lower to mid 70s over the next
few days.

Showers with isolated thunderstorms will continue across portions
of central and southeast AR this afternoon through the evening
hours. Showers will continue to develop along this surface
boundary as it makes its way eastward across the state over the
next day or two.

&&

.LONG TERM...Tuesday Night Through Sunday

H500 ridging will continue to dominate the forecast as it remains in
place across the southern US Wednesday and Thursday. This will
provide continued hot temperatures as well as heat indices at or
above 105 F for much of the forecast area.

By late week into next weekend, mid level ridging appears to shift
eastward, positioning itself over the SE US. This will provide
slightly cooler temperatures as well as an increase in at least some
daily diurnally driven activity across the state. If the ridge
shifts east as depicted by 12z model solutions, tropical development
may take place across the W/SW portions of the Gulf of Mexico.
