Marine Weather and Tides
Gulf Shores, AL

Version 3.4
What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

907 pm cdt Sat jun 23 2018

Discussion See updated information for land areas below.

Update It's a quiet and muggy evening across the region with
an onshore breeze ensuring it will stay that way through the
night. Guidance is indicating an increase in low level moisture
overnight into tomorrow morning (particularly around 925 mb.) this
will likely result in the develop of some late night early morning
patchy stratus, especially closer to the coast. Hi-res guidance
even suggests an isolated shower is possible along the coast early
in the morning and the current forecast handles this well. The
increase in moisture will also likely result in a slightly better
coverage of diurnal storms tomorrow afternoon, but the overall
subsidence from the upper level ridge is expected to still keep
coverage isolated overall.

The big story tomorrow will be the heat indices, which are
currently forecast to be in the 105-108 range in general over the
southern half of the area, and 102 to 106 far inland. A heat
advisory may become necessary for southern portions of the area,
but will let the overnight shift look at new guidance. If
dewpoints mix out a little more than currently indicated or
convective coverage increases a bit more, this may preclude
overall heat indices reaching the critical 108 degree mark.

Regardless, everybody is encouraged to stay well hydrated and
take frequent breaks if working outside. 34 jfb

discussion... Updated for latest aviation discussion below.

Aviation...

00z issuance... PredominateVFR conditions are expected through the
next 24 hours. Increasing moisture overnight via low level
southwesterly winds will likely result in at least scattered low
clouds developing after midnight. Cannot rule out periods of MVFR
cigs along coastal areas, but currently not confident enough in
the chances to include a predominate cig in the forecast. A s
scattered diurnal CU field will develop with the heat of the day
on Sunday with only a small chance of isolated showers storms.

prev discussion... Issued 345 pm cdt Sat jun 23 2018
near term now through Sunday ... Will start this forecast period
with the axis of a broad trof of low pressure at high levels from
the mid ms river valley to the central appalachians. A series of
mid level impulses have been riding eastward at the base of the
upper trof and will provide enough ascent for an active zone of
deep convection aligned from the red river valley of tx ok
eastward to northern ga. The forecast calls for the most active
zone of showers and storms to remain positioned to the north of
the local area. Meanwhile, a flat mid level ridge evolves over the
deep south and will act to limit coverage of showers and storms
over the local area, to isolated at best. Surface high pressure
holds over the gulf.

For temperatures, overnight lows will be warm and muggy, some 3 to
7 degrees above climatology. Daytime highs on Sunday, look to
average around 3 degrees above seasonal. The feel like temperature
Sunday shows a range of 103 to 108 degrees in heat indices. At this
time, it does not appear to be enough coverage for issuance of a
heat advisory (heat index 108 degrees and greater) for Sunday, but
will continue to monitor. It's always good to maintain heat safety;
tips can be found at
