.SHORT TERM...
(Today through Sunday night)
Issued at 326 AM CDT Sat Apr 27 2024

Upper level trough continues to shift east from the Four Corners and
will continue to drive the Fire Weather threat for today. Winds will
be out of the west to southwest and will be breezy in the 20-30
mph range, with gusts up to 50 mph. The strongest winds are
expected to be in the northwest Panhandles. As far as the dryline
setup, it`s expected to be in the far eastern Panhandles and push
out of the area around 1 to 3 pm. Storms don`t look likely, but
there may be some that fire up right along the east and move
quickly out of the Panhandles into western OK. The severe threat
is pretty low give that by the time the storms go severe, they
will likely be out of our area. We`ll keep any eye on the dryline
position this morning and make sure that everything is on track.
One thing that`s been consistent this past month with the dryline
setups, is that they tend to be a bit further west than the models
depict, and they have been mixing east a bit slower than the
models suggest. So if that`s the case for today, then maybe we`ll
have a slightly better chance for severe weather in our eastern
stack of counties. But right now, it`s just looking like a
critical Fire Weather day in the west and central Panhandles, and
elevated in the east and southeast. Second thing to watch will be
the pacific front that will move in later tonight, as it will help
drive some cooler temperatures in the northwest. Some models
suggested that we might drop into the mid 30s for the northwest
Panhandles, which could lead to possible frost conditions. But
have not gone that cold for the overnight lows, and the winds
might just be high enough to avoid frost. Right now lows tonight
will be in the upper 30s for the northwest to the lower 50s in the
southeast. Also, the pacific front is progged to collide with the
dryline overnight tonight and trigger a line of storms.
Confidence is high that this will not impact our area, as it`s
expected to be east of us, but we will keep an eye on that dryline
as noted before, because if it doesn`t mix far enough east and
starts to retreat, then we could have a second round for the
eastern Panhandles. Again, these are all very low probabilities
(<10%), but still something to note. Something that`s been
interesting in the models is a hint at some low reflectivity`s
just west of the dryline late tonight as the Pacific Front
arrives, and it`s possible that we might get some elevated virga
showers, which could result in some strong wind gusts with no
lightning or thunder associated. Inverted V soundings are
suggested along the eastern Panhandles during this time, but the
mid level CAPE is very low, struggling to get 100-200 J/kg.

On Sunday the upper level trough will be passing to the north, with
some cooler air over the Panhandles.  We expect the highs to be in
the upper 60s to lower 70s for the OK Panhandle and in the mid to
upper 70s for the central and southern Panhandles.  Winds on the
back side of the cold front will not be too bad, only in the 15-20
mph range with some gusts around 25 mph, and that`s really only
expected in the northern TX and the OK Panhandle, with lighter
northerly winds further south.  Sunday night we start transitioning
into a more zonal flow with warmer air returning, and we might even
get an overnight shower or storm riding one of the perturbations in
the zonal flow.  Given how our precipitation chances have been over
the past month (April 9th being the exception), not getting too
excited with any overnight pops tomorrow night.

.LONG TERM...
(Monday through Friday)
Issued at 326 AM CDT Sat Apr 27 2024

Dry and warming zonal flow is expected Monday through Wednesday with
temperatures likely hitting the 80s on Monday and very well we may
have a mixed bag of upper 80s to lower 90s on Tuesday and Wednesday.
Winds will pick up an RH values will come down on Tuesday and
Wednesday for the western Panhandles and this will likely lead to
more elevated to critical Fire Weather conditions.   Thursday and
Friday are a bit more uncertain as another weather system is
projected to clip the Panhandles and could bring some showers or
storms to the area.  Highs have been lowered back into the 70s and
NBM pops are around 15 to 25 percent for the central and eastern
Panhandles.

.AVIATION...
(18Z TAFS)
Issued at 1155 AM CDT Sat Apr 27 2024

VFR conditions are expected to prevail with breezy and gusty
southwest winds (20 to 30 kts gust up to 40 kts possible) through
00Z Sun. After 00Z winds should be light around 10 kts or less
with a weak front bringing north winds closer to and after 06Z. An
upper level system may produce some elevated showers, and with
such dry conditions at the surface these showers may be virga and
could cause some erratic winds between 04Z and 08Z mainly.
