Area Forecast Discussion...UPDATED
National Weather Service Mobile AL
157 PM CST Sat Jan 28 2017

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

&&

.UPDATE...Thick cirro-cu streaming northeast across the FA is proving
to be a very effective inhibitor of daytime heating. Have dropped
temps across the FA according from upper 50s to around 50 to low
50s.

/16

&&

.PREV DISCUSSION... /issued 1131 AM CST Sat Jan 28 2017/

DISCUSSION...See updated information for land areas and aviation
discussion below.

UPDATE...Looking at current observations around the area, the
current forecast is on track. Still looking at highs in the mid to
upper 50s across the FA, today.

/16

AVIATION...
18Z issuance...VFR CIGS/VISBYS expected through the forecast under
thick cirro-cu streaming west across the FA. No drops to MVFR levels
noticed upstream.

/16

PREV DISCUSSION... /issued 524 AM CST Sat Jan 28 2017/

DISCUSSION...Updated for latest aviation discussion below.

AVIATION...
12Z issuance...Broken to overcast mid and upper level clouds with VFR
ceilings expected to persist through most of the forecast period,
though some clearing could occur late Saturday evening. Light
northwest winds this morning become westerly at around 10 knots
Saturday afternoon before decreasing to around 5 knots once again
Saturday night into Sunday morning. /49

PREV DISCUSSION... /issued 226 AM CST Sat Jan 28 2017/

NEAR TERM /Now Through Saturday night/...A series of upper-level
impulses rotating around a large area of low pressure over eastern
Canada deepens a broad longwave trough and push it southeast over
the eastern CONUS through the day Saturday. As this trough begins to
push off into the western Atlantic Saturday night, zonal flow over
the Deep South is replaced by northwest flow which will support
another reinforcing blast of cool air Saturday night as a dry
surface cold front passes through the local area and high pressure
builds in from the west. Mid and upper level clouds and cooler-than-
seasonal temps (mid to upper 50's areawide) will continue Saturday
afternoon before the clouds clear some Saturday night and
temperatures drop into the upper 20's to low 30's inland and mid to
upper 30's near the coast. A light freeze will be possible for the
interior early Sunday morning, particularly for areas along and
north of highway 84. /49

SHORT TERM /Sunday Through Monday night/...A sharp upper trof over
the eastern states broadens while shifting into the western Atlantic
through Monday morning, followed by a second system which advances
into the Great Lakes region through Monday night and begins to reform
an upper trof over the eastern states. A surface ridge builds from
the southern Plains and across the northern Gulf during the period,
with northwesterly surface winds over the forecast area becoming
light southwesterly by Monday night. Dry conditions continue for the
forecast with highs around 60. Lows Sunday night will be mostly in
the mid 30s. Lows Monday night range from the upper 30s inland to the
mid 40s at the coast. /29

LONG TERM /Tuesday Through Friday/...An upper trof over the eastern
states shifts into the western Atlantic while an upper ridge over the
western states weakens while shifting into the Plains. A surface
ridge over the northern Gulf weakens through Wednesday while a
trailing cold front, associated with a surface low well to the
northeast, slowly moves into the Gulf coast states and stalls. The
frontal boundary lingers over the region through Friday, and while a
dry forecast is expected to continue through the period, expect to
rain chances return over the weekend. Highs on Tuesday will be in the
mid to upper 60s and trend somewhat warmer to near 70 for Wednesday
into Friday. Lows Tuesday night range from the lower 40s well inland
to the lower 50s at the coast, then likewise trend a bit warmer
through Thursday night to the mid 40s inland with mid 50s at the
coast. /29

MARINE...A moderate northwest flow continues through the day
Saturday before building from the northwest late Saturday night in
the wake of a dry cold front moving across the marine area. Seas 2
to 3 feet Saturday afternoon increase to 4 to 7 feet late Saturday
night in the wake of the cold front and persist into Monday morning.
Small craft advisories may be needed late Saturday night through
early Monday morning as a result. Winds and seas quickly subside
Monday afternoon, with light southwest to westerly flow setting up
into early next week. /49
