.SHORT TERM...
(This evening through Friday)
Issued at 149 PM CDT THU APR 3 2025

Central Alabama remains on the very warm and dry side of the
significant weather that continues to evolve off to our west and
northwest. A 592 decameter ridge is holding firm across the
southwestern Atlantic, which is keeping the fire hose of moisture
and train of disturbances across eastern Texas all the way into
the Ohio River Valley. With the cap of warm air aloft due to the
upper level ridge, rain chances will remain minimal, aside for an
isolated shower or storm across our far western-most counties. A
few showers have actually developed over the last couple of hours
in these areas, and will add a slight chance PoP to the forecast
through this afternoon. Otherwise due to the tight surface
pressure gradient continuing, breezy southerly winds of 10 to
15mph with gusts up to 25mph can be expected. We`ll be very close
or will set additional record highs again today, as we top out
near or just above the 90 degree mark areawide. Winds will
diminish somewhat overnight, but the boundary layer should remain
mixed. We`ll only drop down into the upper 60s to lower 70s as
isentropic lift develops low stratus clouds after midnight.
Following mostly overcast conditions Friday morning, clouds are
forecast to mix out by the afternoon with breezy southerly winds
continuing. A slight chance of a few showers and perhaps a storm
will hold on in the far western counties, so almost a rinse and
repeat forecast from what we`re observing today as temperatures
rise once again into record-breaking territory Friday afternoon.

.LONG TERM...
(Friday night through next Wednesday)
Issued at 149 PM CDT THU APR 3 2025

The weather story for this long-term will remain the severe weather
chances for Saturday Night, lingering into Sunday afternoon. The
trough and cold front still look like they`ll begin shifting east
sometime during the day on Saturday, with the first round of
thunderstorms anticipated as early as 3AM Sunday. However, the
timing with this system is still leaving a lot in question, as the
goalposts remain quite large. Right now, there appears to be almost
a six hour spread on when this line could move in, so hopefully we
have a better picture on timing here in the next day or so.
Regardless, this line will be capable of producing damaging winds,
and isolated tornadoes.

It`s also looking like this line will be capable of very heavy
rainfall, with 2-4 inches of rain possible along and north of I-20
in a very short period of time. While we don`t anticipate any
prolonged flooding, isolated flash flooding will certainly be
possible given these heavier rainfall rates.

Thankfully, we`ll swing to the other end of the temperature spectrum
by the start of the new workweek. Well below average temperatures
are expected by Monday, with highs generally ranging in the low-60s,
and overnight lows ranging in the upper-30s and low-40s.

VFR TAFs are expected for this evening and then MVFR cigs are
expected to develop/swing into C AL from the S/SW from 06-09z.
All sites should go back to VFR by 16-17z. Gusty SRLY winds will

be possible during the day on Friday. Rain chances should stay
generally to the NW of all TAF sites.

steady from the south through Sunday, before swinging towards the NW
come Monday.
