Near Term [through Tonight]...
The large scale Srn stream pattern this evening is highlighted by a cutoff low over Baja Mex, weak ridging over Wrn Gulf and largely fast zonal flow across rest of Nrn Gulf region with RRQ of upper Jet over marine area.
Enhanced divergence downstream from low plus proximity of jet aided in cyclogenesis over the Wrn Gulf waters and in thin mid-upper clouds spreading Ewd over local area.
At surface... high pressure is centered over Ern Gulf with NW-SE oriented ridge over local area.
Looking north...weak WSW-ENE cold front across Cntrl AL and N/Cntrl GA keeping local area in warm sector.
Looking west...an inverted trough of low pressure was noted from low NE LA Swd into Gulf of Mex.
Ahead of low...earlier assocd light rain over our marine area was dissipating.
Overnight...Baja low will move Ewd into interior of Mex.
The upper jet will exit into Wrn Atlc with thin mid-high clouds decreasing W-E.
This should also shut down any precip and lower clouds should
Not an ideal radiational cooling environment. However...with boundary layer moisture in place and area pre-dawn soundings with PWATS around 1 inch plus low clouds eroding and light winds... expect patchy fog.
The focus will be over nearshore Panhandle waters and adjacent coastal counties.
Local confidence tool all show some fog in this area.
Under Wly flow sfc-high levels...expect mild lows...48 to 50 degrees.
Short Term [Monday through Tuesday Night]...
Much of the early part of the week will be marked by warm weather
and daily afternoon sea breezes.
With water temperatures near the coast around 60 degrees, and high temperatures at least into the upper 70s, the sea breeze circulation could be fairly strong.
For Monday`s high temperature forecast, model guidance is clustered in the upper 70s; we have followed that closely.
On Tuesday, boundary layer flow increases out of the southwest, which should push 850mb temperatures into the +12 to +13C range.
With fairly deep mixing, this could allow some stations to hit the 80 degree mark. The only potential limiting factor would be increasing mid-high level cloud cover later in the day.
For now, we`ve nudged highs up at TLH and VLD to 80 and 82 degrees respectively.
For Tuesday Night, rain will begin arriving as a closed mid-upper
level low currently over the Gulf of California will eject east along the Gulf coast.
It should devolve into an open wave by the time it reaches our area, and the trend will be for it to deampilfy.
Initially the strong shortwave approaching the Gulf may be sufficient to create a weak surface low Monday Night or Tuesday morning in the northwest Gulf.
However, this may weaken into more of a pre-frontal surface trough by the time it pushes further east, with the main cold front expected to be further northwest.
Therefore, overall forcing will become weaker with time and this
should limit rainfall in our area on Tuesday Night.
We maintained the "likely" PoPs (~60%) over the area, with QPF around 0.25".
Long Term [Wednesday through Sunday]...
The primary cold front is currently forecast to arrive in the northwest part of our forecast area around 18z Wednesday - per model consensus - before sweeping through in the afternoon.
This should allow for another fairly warm day with the possibility of some light rain showers.
After that, strong CAA will bring a period of below normal temperatures with some frost potential by Thursday Night as high pressure settles over the area.
Temperatures should then gradually moderate into next weekend ahead of the next digging shortwave trough, which looks to arrive late Sunday or Monday.
Aviation...[Through 00z Tuesday]
VFR conditions will prevail through the period with cigs above 15kft along with light winds Monday afternoon.
A brief period of patchy fog may develop around daybreak at all sites
but did not include in TAFS.
Fairly light winds are expected through Tuesday, before southwest
winds increase ahead of an approaching cold front Tuesday Night
SCEC-level (15-20kt) winds seem likely ahead of the front, with advisory winds likely behind the front on Wednesday Night and early Thursday.
Relative humidity levels will remain above critical thresholds through mid-week.
On Thursday, relative humidity values will drop to the 20s in the wake of a cold front, but winds should remain below red flag criteria.
No red flag conditions are anticipated over the next week.
There are currently no hydrology concerns across the region with a
few rivers in Action stage.
The trend for the next week for these rivers will be steady-state or subsiding.
The next system bringing rain to the area will be Tuesday evening through Wednesday evening but total rainfall amounts will be less than half an inch over any given location.
