.SHORT TERM (Today through Sunday)...

Satellite imagery shows the upper low over northeast Oklahoma
while the next upper trough moves into southern California. The
upper low will move through the Ozarks today and northeast into
the western Great Lakes region Sunday afternoon. The second system
will be close behind moving through the Rockies tonight and into
central Kansas Sunday afternoon.

Strong low level flow along the coast early tonight has moved to
the east. Winds have decoupled over the inland coastal plains and
patchy fog will occur in advance of the front. The cold front was
just west of College Station to San Antonio to Eagle Pass at 09Z.
Latest HRRR shows isolated convection could occur along the front
as it moves south through the Victoria Crossroads this morning.
Kept slight chance PoPs for mainly the early part of this morning.
The front will push through the coastal areas and near shore
waters by noon. The boundary then stalls over waters this
afternoon with winds quickly turning around to easterly.

Surface low pressure area forming over West Texas Sunday will
move to southwest Oklahoma by 00Z Monday as the upper trough moves
out into the south-central plains. Onshore flow will steadily
increase during the day Sunday with breezy conditions expected for
the southern Coastal Bend. Southwesterly flow at 85H will advect
warmer air into the Brush Country with highs expected to be in to
the 90s out west Sunday.

.LONG TERM (Sunday Night through Friday)...

Progressive and active pattern for the southern CONUS through the
period with a procession of short waves moving through. The medium
range guidance is in decent agreement with the general pattern but
the degree of digging, timing, and QPF are not...esply with mid and
next weekend systems.

Initial system Monday looks moisture starved as it shears north of
us. Could be a shower or two Victoria Crossroads but will hold Pops
at 10 pct. Weak front will die out before it reaches the Coastal
Bend with a quick return to strong SE flow as the next system digs
into the southern Rockies Tuesday. This next system still could be
a decent rain producer for parts of the area...esply over the
northeast on Wednesday. There remains a lot of spread in the GFS
ensemble members Wed/Thu so confidence is not super high but the
degree of moisture and instability in place along with moderate
forcing suggests decent convective potential. Plenty of time to
monitor this systems progress...for now tapered PoPs from 60
northeast to less then 10 far west. Will hold onto low PoPs
Wednesday Night into Thursday as much of the medium range guidance
suggests front will hang up near the coast.

For temperatures I remained close to the WPC numbers which once
again came in very close to our blended guidance. No real end in
sight to the unseasonably warm/hot weather in the medium range
unfortunately.

.MARINE...

Moderate south winds will continue early this morning which will
maintain elevated seas at SCA levels through 12Z. Extended the SCA
for the offshore waters until 12Z. Winds will become light as the
front approaches and become weak northerly for a brief period
along the coast. The front will stall over the near shore waters
by this afternoon with winds expected to turn east to southeast by
this evening. Onshore flow will increase to moderate levels Sunday
as low pressure deepens over the southern high plains.
