.SHORT TERM...
(Today through Tuesday)
Issued at 353 AM CDT MON JUN 17 2024

In the short-term, big upper level ridge centered in the Carolinas
early in the period will start its migration northward. Slightly
lowered heights here should lead to a modest abatement of high
temperatures compared to the previous couple days (lower/mid 90s
versus mid/upper 90s). Tropical moisture will also continue to get
guided into the state from the Gulf, especially on the western
periphery of the ridge. This should lead to an increase in diurnal
convection coverage this afternoon west of I-65. An easterly low
level flow on Tuesday will help continue the moderating trend in
temperatures. Interestingly, that easterly flow also looks like it
is going to help push the tropical moisture plume even farther
west, leaving dry conditions for central Alabama on Tuesday.

.LONG TERM...
(Tuesday night through Sunday)
Issued at 353 AM CDT MON JUN 17 2024

An exceptionally strong 500 mb ridge will be in place over the
northeastern United States on Wednesday and Thursday. Our area
will be on the southern periphery of the ridge where easterly
deep-layer flow will be associated with a relatively dry and
moderated Atlantic airmass. Dewpoints in the 60s and afternoon
highs in the upper 80s to lower 90s are expected Wednesday and
Thursday. The moderating effects of easterly flow will wane for
Friday and Saturday as flow weakens, leading to temperatures
trending upward into the mid 90s.

A tropical wave is expected to weaken as it moves westward towards
coastal Florida and Georgia on Friday and Saturday with only a
minimal increase in PWAT values over Alabama. Any showers and
storms on Saturday should be isolated and confined to the southern
part of the area. Slightly greater coverage of diurnal convection
may occur on Sunday as southeasterly flow contributes to moisture
advection.

.AVIATION...
(12Z TAFS)
Issued at 621 AM CDT MON JUN 17 2024

Will keep conditions VFR through the next 24 hour TAF period in
central Alabama. There`s a few echoes showing up this morning on
area radars, but any rain making it down to the ground is quite
light and should not result in any ceiling or visibility
restrictions. Best thunderstorm chances will be in the western
third of the area, and decided to keep the only mention of TSRA in
the TAFs at TCL. Otherwise, fair weather cumulus in the lower
levels, and a blanket of high level clouds up above.

.FIRE WEATHER...

Scattered showers and thunderstorms should be confined mainly
west of Interstate 65 today. 20ft winds will be from the
southeast at 6 to 9 mph, and RH values should range from 40 to 60
percent this afternoon. Rain-free conditions will return for
Tuesday through Friday as easterly winds bring drier air to the
region. This will lead to a downtrend in RH values into the 35 to
45 percent range each day.
