Area Forecast Discussion...UPDATED
National Weather Service Mobile AL
1159 PM CDT Wed Apr 18 2018

.DISCUSSION...Updated for latest aviation discussion below.

&&

.AVIATION...
06Z issuance...A cold front approaching from the northwest moves
through the area late tonight into early Thursday morning with
southwest winds 5 to 10 knots switching to the northwest. The
northerly flow increases to around 10 knots by mid Thursday
morning then decreases to 5 to 10 knots Thursday evening. VFR
conditions prevail through the period except for the potential for
MVFR ceilings and isolated patches of light rain to be present
ahead of the front. /29

&&

.PREV DISCUSSION... /issued 1012 PM CDT Wed Apr 18 2018/

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

UPDATE...The current forecast is generally on track with no
changes planned at the moment. /29

PREV DISCUSSION... /issued 621 PM CDT Wed Apr 18 2018/

DISCUSSION...Updated for latest aviation discussion below.

AVIATION...
00Z issuance...Southwest winds at 10 to 15 knots subside to near 5
knots this evening. A cold front approaching from the west moves
through late tonight into early Thursday morning and brings a
slight chance for rain with winds switching to a northerly
direction. VFR conditions at the beginning of the period will be
followed by MVFR ceilings developing late tonight ahead of the
front, then return to VFR conditions in the wake of the front. /29

PREV DISCUSSION... /issued 358 PM CDT Wed Apr 18 2018/

NEAR TERM /Now Through Thursday/...An upper low pressure area
over the midwest states will swing east across the eastern conus
through the near term. An area of low pressure at the surface
across the Ohio River Valley will lift quickly northeastward,
reaching the northwest Atlantic by late Thursday afternoon. A
surface cold front associated with the low pressure area will
approach the region from the northwest this evening as a surface
ridge extending from the western Atlantic across northern gulf
weakens. The cold front will pass through the forecast area after
midnight into early Thursday morning, bringing with it a band of
clouds, and isolated to low-end scattered light rain showers or
sprinkles. /22

SHORT TERM /Thursday night Through Saturday night/...A drier and
cooler airmass moves into the area Thursday night as high
pressure builds across the northern plains and shifts east into
the Great Lakes by Friday night. As the ridge of high pressure
shifts east, moisture levels will begin increasing across the Gulf
Coast as a southeast flow develops on Saturday. Rain chances
increase by Saturday night as a developing southern stream upper
low moves toward the area. /13

LONG TERM /Sunday Through Wednesday/...As this system moves
across the southeast on Sunday, numerous showers and thunderstorms
can be expected Sunday into Sunday night. The GFS remains the
faster model with the upper and sfc lows east of the area by
Monday. Meanwhile, the ECMWF stalls the system over the southeast
through Tuesday. For now, will maintain the highest coverage of
showers and storms Sunday afternoon into Sunday night. Still too
early to diagnose any potential of strong to severe storms and
heavy rainfall potential given model uncertainties. Temperatures
will generally be near normal through the period. /13

MARINE...A light to moderate southwest wind flow can be expected
over the marine area early tonight as high pressure continues to
stretch from the western Atlantic to the north central gulf. A
moderate to occasionaly strong offshore flow is expected late
Thursday and Thursday night in the wake of a cold front that moves
across region early Thursday. A moderate to strong east to southeast
flow is expected Saturday through early next week ahead of another
cold front approaching from the west. /22
