area forecast discussion
national weather service mobile al
1008 am cdt Mon may 20 2019

Discussion See updated information for land areas below.

Update
Surface high pressure positioned over the deep south this morning
will slowly shift east today. Upper level ridging over the
western gulf of mexico will gradually build northeast during the
day and this should help to suppress the overall coverage of
mainly afternoon convection. High resolution cam guidance does
still generate some isolated convection, especially along a
developing sea breeze circulation that will advance inland as
strong inland heating continues through the day. Regional 12z
soundings suggest little in the way of capping, but a subsidence
inversion should develop with time with the building ridge aloft.

Overall will keep pops capped below 20 percent through the
afternoon considering all of the forecast factors expected.

All of the morning fog has mixed out and broken morning stratus
has also scattered. Hot and humid conditions are expected with
high temperatures expected to range from the middle 80s along the
coast to lower 90s inland. Dewpoints should remain in the upper
60s to lower 70s this afternoon, making conditions feel
uncomfortable with long outdoor exposure.

Overall the forecast looks good and only made minor adjustments to
remove morning pops and fog.

Aviation...

12z issuance... Some patchy fog and low clouds over the area will
dissipate shortly after issuance time leavingVFR conditions.

Light and variable winds at the beginning of the period become
southeast to south 5 to 10 knots today, then returns to a light
and variable flow tonight. Patchy fog is expected to develop again
late tonight. 29

Prev discussion issued 333 am cdt Mon may 20 2019

Near term now through Monday night A shortwave trof
currently over the area moves off to the east this morning followed
by an upper ridge building over the region this afternoon into
tonight. A surface low well north of the region brings a rather
weak frontal boundary (really just a wind shift) southward into
central alabama this morning which lingers into the afternoon. A
surface ridge currently extending along the northern gulf coast
shifts into the northern gulf in response. With the aid of a modest
sea breeze circulation, this pattern sets up a weak low level
convergent zone mainly during the afternoon hours. The modest
subsidence may prove strong enough to suppress convective development
today, but per coordination have opted to keep in slight chance pops
for possible development with the weak low level convergent zone sea
breeze. The wet microburst potential today is low. Highs today
near the coast will be in the mid upper 80s and mainly around 90
elsewhere. Lows tonight range from the mid 60s inland to around 70
at the coast. Will continue with a high risk of rip currents today
due to a continuing spring tide, onshore swell 2 ft 6 sec, and
onshore flow up to 10 knots. A moderate risk of rip currents
follows for tonight as the swell is expected to subside. 29

Short term Tuesday through Wednesday night An upper ridge
builds over the eastern CONUS through the short term as the flow
pattern aloft becomes more amplified. Strong subsidence beneath
this ridge will keep skies mostly clear over the local area
through the period. High surface pressure builds over the region
as well, which results in a diffuse pressure gradient and light
surface winds that will be primarily driven by diurnal mesoscale
processes (e.G. Land sea circulations). Temps begin a gradual
warming trend as highs reach the upper 80s to low 90s each day.

Lows stay in the mid to upper 60s inland and closer to 70 along
the coast each night. 49

Long term Thursday through Sunday Both the upper-level and
surface ridge axes move little through the long term, continuing
our dry weather and hot temperatures through the remainder of the
work week and straight into next weekend. Highs reach the upper
80s and low 90s along the coast and mid to upper 90s inland each
afternoon. Some inland locations could approach 100 degrees by
the weekend. Lows stay in the upper 60s to low 70s each night. 49

Marine A light to occasionally moderate southerly flow is
expected through Friday. Seas will be generally 2 to 3 feet. 29

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
