Area Forecast Discussion
National Weather Service Mobile AL
1142 AM CST Sat Dec 1 2018
.DISCUSSION...Updated for latest aviation discussion below.
&&
.AVIATION...
18Z issuance...
Ongoing thunderstorms and low clouds lead to majority IFR and MVFR
conditions expected through the day today. Winds are expected to
remain out of the southwest. Overnight fog with IFR or worse
visibilities will become a possibility after midnight mainly
along the coastline. Even after sunrise low clouds should linger
through mid morning. DJ/17

.PREV DISCUSSION... /issued 543 AM CST Sat Dec 1 2018/
DISCUSSION...Updated for latest aviation discussion below.
AVIATION...
01/12Z Issuance...LIFR to IFR ceilings expected through much of
the morning hours, especially in the vicinity of scattered to
numerous showers and thunderstorms where IFR visibilities likely
as well. A few strong or maybe severe thunderstorms will be
possible mostly near the coast between 01/14z and 01/18z. Winds
will generally be out of the south at 10 to 15 kts with higher
gusts near showers and storms. 12/DS
PREV DISCUSSION... /issued 420 AM CST Sat Dec 1 2018/
NEAR TERM /Now Through Saturday night/...The potential remains
for severe weather impacts and heavy rain across our forecast area
today as a strong storm system over south central Kansas lifts
northeastward toward the upper Mississippi Valley region through
tonight. Our area will be in a broad warm sector ahead of this
system with temperatures increasing into the lower to mid 70s
today as a strong southerly flow advects gulf warmth and moisture
into the area. A fast moving mid to upper level disturbance
southeast of the main storm system will pass over the area this
morning, keeping an organized area of ongoing showers with
embedded thunderstorms through noon. Heavy rainfall potential
remains mainly east of I-65 where an additional 1 to 3 inches with
localized higher amounts will be possible.
The atmosphere will become increasing unstable across our forecast
area this morning as warm advection spreads inland, with MLCAPE
values rising to 1000 to 1500 J/KG. However the highest wind shear
currently over the forecast area will move eastward, with Sfc-3km
SRH values dropping from 300 to 400 m2/s2 to between 100 to 200
m2/s2 by noon. A few storms still have the potential to produce
damaging winds and possibly a couple of tornadoes going into early
afternoon until the mid to upper level disturbance moves east of the
area. Isolated to scattered light rain showers will remain overnight
east of the Alabama River. /22
SHORT TERM /Sunday Through Monday night/...Sunday, rain is
expected along and southeast of a weak surface front stalled over
the area as a weak low level jet max over the area moves northeast.
With less cloud cover allowing for more daytime heating, highs in
the mid 70s are expected, well above seasonal for the date.
A strong mid level shortwave passing north of the area later Sunday
night through Monday develops a surface low over the northwest Gulf,
then takes it northeast over the area along the front. Another round
of rain and thunderstorms is the result before the exiting energy
pushes a cold front across the area Monday night. Lows Sunday night
are expected to range from around 50 northwest to around 60 along
the coast. Monday will see cooler temps than Sunday due to the
increase in rain coverage, and are expected to range from mid 60s
northwest to around 70 southeast. The cooler air overspreading
the area Monday night behind the front will bring temps dropping
to the upper 30s north to near 50 along the coast.
/16
LONG TERM /Tuesday Through Friday/...Surface high pressure moves
east from over the Plains, passing over the area Thursday. This
maintains a cooler, dry northerly flow over the area through
Thursday. Temps dropping below freezing are expected Tuesday and
Wednesday nights over most of the area, with highs in the 50s
expected Tuesday through Thursday.
The surface high pressure moves east of the area Thursday night into
Friday, bringing return flow off the Gulf back to the area. Temps
begin to increase along with moisture levels, with lows Thursday
night ranging from the upper 30s northeast to mid 40s along the
coast. Highs in the low to mid 60s expected Friday.
/16
MARINE...A strong southerly wind flow along with high seas can be
expected today as a storm system moves across the region. Showers
and thunderstorms are expected through early next week with a few
strong storms possible through this afternoon. A strong cold front
is expected to move through the marine area Monday night, leading to
a moderate to strong offshore flow through midweek. /22
