Area Forecast Discussion...UPDATED
National Weather Service Mobile AL
1051 PM CST Tue Jan 24 2017

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

&&

.AVIATION...
06Z issuance...VFR conditions will prevail through much of the
period. Some patchy MVFR fog is possible very early Wednesday
morning. Rain chances increase after 26.00Z as a cold front
approaches the area. /13

&&

.PREV DISCUSSION... /issued 650 PM CST Tue Jan 24 2017/

DISCUSSION...Updated for latest aviation discussion below.

AVIATION...
00Z issuance...VFR conditions will prevail through the entire period.
Southerly winds will increase along with increasing high and mid
level clouds through the day on Wednesday. /13

PREV DISCUSSION... /issued 359 PM CST Tue Jan 24 2017/

NEAR TERM /Now Through Wednesday/...A southerly return flow will
develop overnight on the backside of a surface high pressure
ridge moving east toward the western Atlantic. Nearly zonal flow
aloft will transition to a southwest flow as an upper trough over
the western conus moves east over the Great Plains. An associated
cold front extending from the midwest states to the southwest states
will approach the forecast area late Wednesday afternoon. Low
level moisture will increase overnight, allowing patchy fog to form
across most inland areas late tonight into Wednesday morning. Rain-
free conditions will persist across the entire forecast area through
mid Wednesday afternoon, followed by isolated showers affecting areas
along and west of a Butler AL to Wiggins MS line late in the
afternoon.

Low temperatures tonight will range from 43 to 49 degrees most
inland areas, with lower 50s along the coastal sections and mid 50s
at the beaches. Very warm temperatures will return on Wednesday with
afternoon highs ranging from 73 to 78 degrees. /22

SHORT TERM /Wednesday night Through Friday night/...
Cold front extending from the central Ohio river valley down to the
Gulf Coast continues its eastward trek through the forecast area
overnight Wednesday exiting the area early Thursday morning. With it
bringing in increasing rain chances with some embedded thunderstorms
overnight. The main dynamics with this system is located well into
the Great lakes region. Consequently, the principle source of lift is
anticipated to be cold airmass wedging. Surface high pressure will
slowly build from the west Thursday and Friday. This in addition to
northwesterly winds will limit high temperatures to the mid 50's.
Concurrent clear skies should allow for temperatures overnight
Thursday and Friday to dip into the mid to upper 30's. 17/DJ

LONG TERM /Saturday Through Tuesday/...
A series of dry mid-level trough move over the forecast area Saturday
and Sunday night. This will keep a synoptic status quo of light west
to northwest winds, max temps in the mid 50s, and minimum
temperatures in the mid to low 30s for the weekend. Early next week
following the passage the Sunday night trough expect colder airmass
overhead as high pressure builds during the first half of the week.
17/DJ

MARINE...
A ridge of high pressure over the central Gulf coast moves
off into the western Atlantic through Wednesday while a cold front
approaches from the west. A light onshore flow becomes established
overnight and gradually increases ahead of the approaching front,
then switches to a strong offshore flow Wednesday night as the front
moves through. A Small Craft Advisory may be required for most of
the marine area Wednesday night through early Thursday morning until
the offshore flow subsides. /22
