.SHORT TERM...
(Today through Sunday)
Issued at 324 AM CDT SAT JUN 15 2024

A ridge in place over Central Alabama will result in highs in the
mid to upper 90s across the area today. Highs have trended
downward a couple degrees with this latest update, with most areas
across Central Alabama remaining at 98F or below. CAMs have shown
the potential for a few showers or thunderstorms this afternoon,
so have added slight chance PoPs in the east for the afternoon and
evening hours. Heat index numbers should remain largely in the
100-105F or below, so a Heat Advisory will not be issued. As the
ridge slides eastward Sunday, southeasterly flow will hold highs
mainly in the mid 90s. Shower and thunderstorm potential looks
comparatively more likely than today, so went with slight chance
PoPs across most of the area and chance PoPs south of I-85.

(Sunday night through Friday)
Issued at 324 AM CDT SAT JUN 15 2024

A deep-layer ridge will be centered over North Carolina on Monday,
opening the door to south-southeast flow in the 850-500 mb layer
across Alabama. This will lead to a significant increase in PWAT
values over the western third of our state. A moisture gradient
from west to east will correspond with POPs ranging from 50
percent along the AL/MS state line to 20 percent on our eastern
border. The ridge axis will swing back to the west on Tuesday, and
as flow becomes more easterly, PWAT values should drop below 1.5
inches across most of the area. Accordingly, any showers and
thunderstorms should be isolated in nature and confined to our
western counties.

A large area of subsidence and below normal moisture content will
persist across the region for Wednesday and Thursday with no rain
expected. A tropical wave embedded within easterly flow could
begin to reach our eastern counties on Friday along with a slight
increase in rain chances.

Dry conditions are expected through Sunday morning, with the
exception of a couple showers or storms east of I-65 this

afternoon across much of the area, although coverage still looks
to be fairly limited. 20- foot winds will be light and variable
through Sunday morning, becoming southeasterly up to 6-8 mph
through Monday evening. Afternoon min RH values are expected to
drop into the 35-45 percent today and Sunday.
