.UPDATE...

No significant updates were needed for tonight.

.NEAR TERM...
(Through Sunday)
Issued at 219 PM EST Sat Feb 22 2025

Clouds stream in from the west tonight into Sunday. Temperatures
tonight will be a bit warmer than the past few nights, thanks in
part to those clouds, with lows in the middle 30s to near 40
around the region. A few peeks of sunshine early Sunday morning
will allow temperatures to warm into the 50s, maybe lower 60s,
before more clouds and some rain arrives later Sunday afternoon.

An H5 trough, which can easily be seen on the mid-level water
vapor imagery on GOES-16, moving through northern Mexico travels
through the Southern Plains and spawns an area of low pressure in
the western Gulf this evening. The low trudges along the northern
Gulf tonight into Sunday, bringing ample cloud cover along with
it. Rain is forecast to spread over the region from west to east
Sunday afternoon. Have elected to speed up the arrival of the rain
by a few hours compared to the NBM to be more in-line with the
latest hi-res guidance. In doing so, temperatures have been bumped
down a degree or two Sunday afternoon to account for this. That
said, if the rain arrives later than expected, temperatures would
be warmer.

.SHORT TERM...
(Sunday night through Monday night)
Issued at 219 PM EST Sat Feb 22 2025

The short term period begins with an area of low pressure in the
Gulf waters moving eastward just offshore of the Florida
Panhandle. Upper support in association with this surface feature
seems to be more pronounced this model cycle in both the Euro and
GFS. As a result, rain chances in the 12z model cycle in both
these two models and other ensemble members has increased. Thus,
will be increasing PoPs for Sunday night into the categorical
range in the south and tapering down to likely PoPs across our
northern areas. While this will not be a heavy rain event,
everyone is expected to get at least some light rain before the
low completes its transit across the Gulf and into the Atlantic.

By late Monday morning and into Monday afternoon, strong drying
aloft as a result of the trough digging into the Central Gulf,
will lead to decreasing cloudiness from west to east, and an end
to rain chances across the region. Since the system is mostly
Pacific in origin, there is little in the way of cool air behind
the system so overnight lows on Monday into Tuesday will only fall
into the low to mid 40s.

&&

.LONG TERM...
(Tuesday through Friday)
Issued at 219 PM EST Sat Feb 22 2025

The long term period will feature a period primarily of tranquil
weather, however, model guidance does show a frontal system
approaching the area on Thursday. During the first half of the
period, surface high pressure will build over the Northern Gulf
keeping the area clear and dry, but by Late Wednesday, an
amplifying northern stream trough will drop out of Canada into the
upper Midwest en route to the Ohio Valley by late Thursday. This
will push a surface frontal feature toward the Gulf coast states.
This positively tilted and quick-moving upper trough will provide
some lift for precipitation, but given the lack of significant
return flow ahead of the boundary, rainfall will be tough to come
by. Thus, have only shown modest rain chances with this frontal
passage and given the lack of return flow have kept thunder out of
the forecast with Thursday`s system.

Beyond Thursday, high pressure will build back into the region and
while a brief cool down of a few degrees is expected across the
board, the airmass will moderate quickly with temperatures warming
into the coming weekend.

.AVIATION...
(06Z TAFS)
Issued at 1255 AM EST Sun Feb 23 2025

VFR conditions are expected to prevail through most of the day
today. However, rain and lower ceilings will move into the area
from west to east late in the day into the overnight hours in
association with a weak area of low pressure. MVFR to IFR
conditions are expected with this rain.

&&

.MARINE...
Issued at 219 PM EST Sat Feb 22 2025

A disturbance will move across the Gulf on Sunday evening,
resulting in an increase of northeasterly winds and widespread
rain. By Monday, this system will move east of the marine area
with a return of relatively tranquil conditions for the waters
through Wednesday. A cold front will cross the marine area on
Thursday with an increase in offshore winds in its wake.

&&

.FIRE WEATHER...
Issued at 219 PM EST Sat Feb 22 2025

Rain is forecast to arrive late Sunday afternoon and be exiting
early Monday morning. Rainfall totals on the order of 0.1" to 0.5"
is expected, with the higher amounts mainly confined to the Florida
districts. Otherwise, light and variable transport winds are
forecast Sunday. MinRH values will be on the increase the next
couple of days before drier weather arrives Tuesday.

&&

.HYDROLOGY...
Issued at 219 PM EST Sat Feb 22 2025

While the region will get rainfall on Sunday night into Monday,
amounts are expected to be less than a half inch of rain, so there
are no flood concerns with this system. Moreover, Thursday`s
system should deliver little if any rainfall as the front moves
through, so do not expect any flood concerns through the forecast
period.
