What's New / NOTES
6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported.
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.
5/19/2016 - There were issues with the 3 day airport observation history. I switched to another data source. Let me know if you see any issues with the data feeds.

GMZ600 Synopsis For Destin Fl To Pascagoula Ms Out 60 Nm Including Mobile Bay- 1000 Am Cdt Fri Aug 18 2017
Synopsis..Surface high pressure continue across the northern gulf of mexico today, weakening slightly Saturday as a weak front approaches from the north. This will result in a light west to southwest wind flow through late Saturday, but briefly northwesterly late night and early morning hours. Weak high pressure builds north of the area Sunday into early next week with winds becoming more east to southeasterly. Little change in seas expected. Winds and seas higher in and around isolated to scattered showers and storms.

Discussion Updated for latest aviation discussion below.

Aviation
18 12z issuance...VFR condtions expected to prevail across the region
through most of the forecast period. Expect a persistence forecast
today and tonight, with development of isolated to scattered shra tsra
by this afternoon, ending after sunset this evening. Surface winds
generally light, primarily out of the west. 12 ds

Prev discussion issued 415 am cdt Fri aug 18 2017
near term now through Friday night ... Convection was rather limited
yesterday afternoon as compared to previous couple of days, as
expected, although there were a few showers and storms around. For
today, expect similar conditions but perhaps a few more showers
and storms this afternoon mainly confined to the southern half of
the forecast area. Upper ridging weakens slightly in the near
term, with the tail end of a weak mid upper level shortwave moving
west to east across the forecast area today. Meanwhile, a surface
high pressure ridge axis along the gulf coast this morning is
expected to drift further offshore through tonight as a weak
front trof drifts well south into the area. Subsidence will be a
little less pronounced today, and the surface front trof moving in
from the north will provide a low level focus. This combined with
pwat's still ranging from around 1.3 inches over northern inland
zones to near 2.0 inches at the coast, should result in isolated
to scattered convection across southern portions of the forecast
area this afternoon. No severe threat expected with the isolated
to scattered storms, but localized heavy rain, lightning and brief
strong gusty winds can be expected with any storms that do
develop. Most of the convective activity will be this afternoon,
diminishing quickly after sunset with loss of instability. With
abundant sunshine today, especially early, should be another hot
day today, but high temps likely a few degrees lower than
yesterday in most locations. MAX temps this afternoon are
generally expected to be in the lower 90s for most locations,
except for along the immediate coast where some upper 80s are
possible. Low temps tonight still warm, in the low to mid 70s
inland and mid to upper 70s at the coast. Muggy conditions
continue. 12 ds
short term Saturday through Sunday night ... On the southern
periphery of a mid level ridge nosing westward over the deep
south over the weekend, a well defined upper level trof moves
westward over the gulf. Deep layer moisture, with precipitable
water (pwat) values around 1.5 inches on Saturday, lies between 1
and 2 standard deviations below the climatological mean as we
begin the latter half of august. Although there is some influence
of larger scale subsidence from ridge aloft and on the northern
and western flank of westward moving upper trof to the south,
cannot discount a chance of showers and storms during the heat and
instability of the day as deep layer moisture will be adequate.

Daytime highs on Saturday most locations look to rise to between
93 and 96. Heat index values lift to between 102 and 107.

Overnight lows Saturday night 72 to 75 interior to mid to upper
70s coast, with potential of late night showers and storms closer
to the coast and offshore.

As the axis of the upper trof pivots slowly west over the central
gulf on Sunday, highest deep layer moisture recovers to around
1.8 inches along the coast thru the day. Considering this and
transitioning to the more favored eastern side of the trof for
better shower and storm potential, will mention a mid range chance
probability. Over the interior, deep layer moisture looks to
remain about a third of an inch lower in pwat and larger scale
subsidence associated with more upper ridging there suggests a
lower probability than that along the coast. Daytime highs on
Sunday mid 90s along and north of i-10 to lower 90s closer to the
coast. Heat index values 102 and 107. 10
long term Monday through Thursday ... Upper ridge axis off the
southeast us coast, builds west thru the middle of next week,
pushing gulf upper trof westward to the texas coast by Tuesday. A
marked increase in pwat is seen Monday thru Wednesday with values
increasing to between 2.0 and 2.1 inches on average. Thus, will
mention a chance of daily storms during the better instability of
each day. A diurnal decrease in night-time convection over the
interior while maintaining small probabilities closer to the
coast and offshore overnight, which is common in summer. Highs in
the lower to mid 90s interior to 87 to 90 coast. Heat index values
to mostly range 100 to 105. Overnight lows in the mid 70s
interior, 77 to 80 closer to the coast. 10
marine... A surface high pressure ridge axis will continue to extend
west across the northern and eastern gulf of mexico through today,
but begin to weaken slightly by Saturday as a weak front approaches
the gulf coast from the north. This pattern will result in a
generally light west to southwest wind flow through late Saturday,
but at times a brief northwesterly component in the late night and
early morning hours. High pressure will again build to the east of
the marine area Sunday into the early part of next week with winds
becoming more predominant east to southeast. Little change in seas
expected, generally remaining 2 feet or less through most of the
period, increasing slightly by late Monday into Tuesday. Winds and
seas will however be locally higher in and around isolated to
scattered showers and thunderstorms. 12 ds
