Synopsis..A light to moderate southerly flow will increase Friday night into Saturday as a strong cold front approaches the area. The front will move through the marine area Saturday night with a strong northwest flow developing and continuing through Sunday. Gusts to gale force are possible Saturday night. Southerly flow returns early next week in advance of another approaching cold front.

18z issuance... GeneralVFR CIGS visbys over the area at this time will
see drops to ifr or lower levels overnight into Friday morning as
weak cold front moves over the area beginning later tonight. A
band of light rain moving across the area this afternoon is light
enough to not significantly affect conditions as it passes.

Conditions improve as the day progresses Friday, but are expected
to remain at MVFR or lower levels.

discussion... See updated information for land areas below.

Update... Looking upstream (west) from the kmob forecast area, a
band of rain is proving to be a bit stronger and farther south
than originally anticipated. Looking at the latest water vapor
loop, the positively tilted nature of a passing shortwave is in
evidence as it stretches sw-ne north of the forecast area. Also,
guidance continues to advertise weak isentropic upglide in the low
levels remaining northwest of i65. Have bumped pops up and spread
farther east as a result, but have continued to keep the higher
chances of rain over northwestern portions of the forecast area.

near term now through Thursday night ... A weak cold front will
move slowly into the region today and stall just to our northwest
tonight as a weakening shortwave moves across the ohio valley.

Ahead of the front, clouds will increase through the day as
moisture levels increase due to a light southerly flow. Scattered
showers will increase from the northwest and slowly move southeast
through tonight. Weak forcing and the lack of significant deep
layer moisture will keep rainfall amounts light, generally less
than a quarter of an inch in most areas. Increasing moisture will
lead to the development of patchy fog late tonight. Highs today
will range from the upper 50s to the north to low 60s across
southern portions of the area. Lows tonight will generally be in
the low to mid 50s. 13
short term Friday through Saturday night ... A drier zonal mid
level flow pattern will return to the forecast area on Friday,
though some residual weak isentropic ascent may result in isolated
light rain showers flowing from the northern gulf toward the
western florida panhandle and adjacent portions of south central
and far southwest alabama. We will maintain a slight chance of
rain generally along and to the southeast of a luverne to dauphin
island line through Friday afternoon. Low level southerly flow
will otherwise persist across the region as the surface ridge of
high pressure shifts off the southeast u.S. Coast and the next
area of low pressure deepens over the southern plains. Low level
moisture will continue to increase across the area into Friday
night, with surface dewpoints rising into the mid 50s to around 60
degrees. The mid level flow pattern begins to turn more southwesterly
on Friday night ahead of the trough axis that will be translating
across the central and southern plains and toward the mississippi
valley region. Deep layer moisture should be on the gradual
increase underneath the southwest flow pattern aloft Friday night,
and additional ascent ahead of this feature will support a low
chance of rain showers across much of the forecast area, with the
slightly better pops around 30% favored over southeast mississippi
and interior southwest alabama. We may also have to monitor for
patchy fog development across the region again late Friday night
into early Saturday morning. Warmer temperatures are anticipated
Friday, with highs in the mid 60s to around 70 degrees. Increased
low level moisture will also bring above normal temperatures to
the region for Friday night, with lows in the mid 50s to around 60
degrees.

The upper level trough is forecast to progress eastward from the
vicinity of the mississippi valley Saturday morning to across the
tennessee valley and north central gulf coast region Saturday
night into early Sunday morning. A deep area of surface low
pressure centered over arkansas around 12z Saturday morning
should lift eastward across the tennessee valley by early
Saturday evening, before rapidly pushing toward the eastern
seaboard by early Sunday morning. An attendant cold front
trailing south from this area of low pressure will sweep across
our forecast area Saturday afternoon into early Saturday evening.

Large scale ascent ahead of the approaching trough and cold front
will support an organized quasi-linear convective complex that
should enter our western zones sometime late Saturday morning or
early Saturday afternoon, and translate across our region through
early Saturday evening. We have pops increasing to 50-60% over
western portions of our CWA prior to noon Saturday, with
categorical coverage around 80% over the entire region through
Saturday afternoon. Pops should quickly decrease from west to east
into early Saturday evening following the passage of the cold
front. A high shear low CAPE environment will be in place across
our region Saturday, as is typical with a number of our qlcs type
events. Surface dewpoints in the upper 50s to lower 60s may
support MLCAPE values up to 500-700 j kg across our region
Saturday, and this available instability when combined with strong
low level flow (850 mb winds 45-55 knots) may be supportive of a
few embedded bowing segments within the convective line, capable
of producing localized wind damage. A brief, weak tornado also
cannot be entirely ruled out. The day 3 severe weather outlook now
has our entire CWA outlined in a marginal risk for Saturday,
which looks reasonable. Increased winds and colder temperatures
will return Saturday night following the frontal passage. 21
long term Sunday through Wednesday ... A much drier northwest
flow pattern aloft will return to the region on Sunday in the wake
of the frontal passage. Continued breezy conditions are expected
given the mslp gradient. Temperatures will be chilly on Sunday
with highs only reaching the mid 40s to around 50 degrees. Winds
should begin to diminish Sunday night, setting up favorable
conditions for a light freeze with lows in the mid 20s to around
30 degrees over much of the area away from the immediate coast.

The surface ridge moves east Monday, allowing for a return
southerly flow Monday night into Tuesday. The next area of deep
moisture and large scale ascent ahead of another approaching
trough will bring the next good chance of rain to our region
Tuesday into Wednesday, though timing of this next system is still
uncertain. 21
marine... A light to moderate southerly flow will increase Friday
night into Saturday as a strong cold front approaches the area. The
front will move through the marine area Saturday night with a strong
northwest flow developing and continuing through Sunday. Gusts to
gale force are possible Saturday night. Southerly flow returns early
next week in advance of another approaching cold front. 13
