Area Forecast Discussion
National Weather Service Fort Worth TX
220 PM CDT Fri Apr 28 2023

...New Short Term...

.SHORT TERM... /NEW/
Update:
/This Afternoon Through Saturday/

First supercell thunderstorm of the day near the the surface low
triple-point has developed near Evant on Hwy 281 near the country
apex of southern Comanche/western Hamilton/and far northern
Lampasas counties. This classic looking supercell is already
tornado warned and likely contains a small core of severe hail and
very strong winds near the RFD. This cell is moving quite fast to
the at 30 mph and folks in Hamilton need to be taking shelter as
I write this intro. Just the beginning, as we expect more
scattered, strong to severe storms, some with supercell structures
to continue developing along/ahead of the progressive cold front
entering our Big Country and western North Texas counties at the
moment.

High-resolution CAMs runs of the HRRR/RAP, NAMNest/NAM12,TTU WRK
and FV3 models have been quite consistent and in pretty good
agreement since last night. Otherwise, timing trends of both the
strong cold front/surface low and severe storm trends are the
same as the previous short term discussion(s) below, as are
temperatures and the gusty pre/post-frontal passage winds. With
the strong shortwave trough lagging several hundred miles
northwest of the surface front, enough mid level moisture will
coincide with continued strong lift above the front with the
shortwave and very steep mid level lapse rates around 8 deg C/km
for a continuation of isolated-scattered, strong to severe storms
well behind the front for a continued threat of severe hail,
frequent lightning, and heavy downpours as noted from the ongoing,
"special" 18z FWD sounding through later this evening. Also,
substantial and additional convective rainfall for those generally
east of I-35/35W...including the 3 major T.V. markets (DFW,
Waco/Temple/ Killeen, and Sherman/Denison) through mid to late
evening. Don't let your guard down just because you experienced
the frontal passage. You'll know it when it occurs with southerly
breezes 10 to 15 mph quickly shifting N-NW 15-25 mph with higher
gusts.

Decreasing clouds, windy, and colder conditions occur later
tonight across the western half of the forecast area and should
mark the end of the severe weather threat, but not necessarily the
chances for elevated, isolated to scattered showers and storms
across the East. Luckily, any continued activity on Saturday
across East Texas will be more of the general variety. Partly to
mostly sunny conditions are expected elsewhere to the west with
everyone seeing windy conditions through early-mid afternoon with
northwest winds 15 to 25 mph and gusts in excess of 30 mph. After
the chilly lows to start off the day, highs within the dry, cP
airmass advecting into the area will be on the order of 10 to 15
degrees below normal for the last week of April.

Previous Short Term Discussion:
Daybreak Update:
/Overnight through Friday Night/

High clouds will increase in coverage across North Texas this
morning ahead of the approaching shortwave. Patchy fog is also
beginning to show up on the northern and eastern fringes of the
CWA with more extensive fog across Central Texas.

Latest guidance is still in line with our current forecast in
regards to the expected severe weather. Nearly all CAMs continue
to show storms developing near US 281 between 2 PM and 3 PM with a
rapid expansion and movement eastward through late afternoon and
evening. Although much of the CWA has the potential for severe
storms, locations south of the I-20 corridor will have the most
favorable, moisture, instability and shear.

-------------------------------------------------------------------
 Main Midnight Discussion:

 A brief recovery period is underway with subsidence on the back
side of a departing shortwave resulting in a mostly clear sky.
Patchy fog will be possible overnight, especially across the
eastern zones where winds will remain light and current temp/dew
point spreads are only a few degrees. Overnight lows will range
from the upper 40s to the lower 50s.

Low level warm/moist advection will begin early Friday morning in
response to deepening surface low pressure across the Big Country
and Permian Basin. A somewhat complex surface pattern will evolve
across North and Central Texas by midday Friday with a warm front
extending southeastward from the surface low, a dryline extending
southward from the surface low through the Hill Country and a
cold front positioned from the Central Plains, through the Big
Country and into Far West Texas. The surface low is progged to
move into the western CWA by midday while a positively tilted
trough sweeps across the Panhandle and Central Plains. Surface and
mid-level destabilization will both increase by early afternoon,
resulting in rapid storm development between 2 PM and 3 PM with
initiation likely near the intersection of the dryline and warm
front, somewhere between Parker County, Hill, and Erath County.
Of course this point of initiation could change based on where the
surface features ultimately end up, but this is the latest
thinking which also is in line with nearly all of the CAMs. Once
storms initiate, we should be off to the races with multiple
supercells possible given the forecast shear profiles and strong
instability. It does appear that biggest severe threat will favor
the southern half of the area, roughly along and south of the I-20
corridor since this is where the most favorable moisture and
instability will reside. However, just about anywhere across the
forecast area could see strong to severe storms. Large hail will
be the primary threat initially but the potential for some backed
winds near the surface low may be sufficient for a few tornadoes.
As the cold front progresses eastward through late afternoon,
storms should become more linear with an increasing damaging wind
threat along with hail. The surface based storms will march
eastward with the cold front through Friday evening but elevated
storms with a potential for hail will still accompany the upper
trough as it translates eastward through Friday night.

The progressive nature of the system will keep the threat for
widespread flash flooding low. However, precipitable water values
in excess of 1.5 inches across Central Texas and the southern
portions of North Texas along with damp soils from the rain
Wednesday, will result in a chance for localized flooding,
especially with the initial supercells.

Temperatures Friday will be quite variable based on which side of
the various surface boundaries that will be in place. Highs near
the Red River will be in the mid 70s with mainly upper 70s to
lower 80s elsewhere. However, the far southwest zones could
approach 90 degrees with increasing westerly winds behind the
dryline. Lows Friday night will be much cooler with mid 40s to
lower 50s. A strong and gusty post-frontal northwest wind will
make it feel even colder. These strong winds may approach Wind
Advisory Criteria in the pre-dawn hours Saturday.

.LONG TERM... /Issued 1231 PM CDT Fri Apr 28 2023/
/Sunday Onward/

Pleasant and warm weather is expected Sunday as the late Friday
system continues to depart to the east with northwest flow aloft for
North & Central Texas. It'll be quite a bit warmer than Saturday
with afternoon highs in the mid 70s across the northeast while most
of the forecast area reaches the low/mid 80s.

Temperatures in the 70s and 80s will then persist each day through
the extended as shortwave ridging prevails across the Plains with
another trough sent southward across the East Coast. It should be
primarily rain-free through Wednesday, but we'll have to monitor
low storm chances late Tuesday and again late Wednesday currently
positioned just west of the forecast area. Towards the end of the
period (Thursday/Friday), rain/storm chances increase areawide as
the next system approaches.

.AVIATION... /Issued 111 PM CDT Fri Apr 28 2023/
/18z TAFs/

Concerns: Timing development of storms and entry into the D10
airspace, as well as FROPA sometime before 00z Saturday. Cig
trends and strength of both pre/post-FROPA winds/gusts also
challenging with average confidence, though increasing as we
approach the event.

After a look at new short term, high-res model data and detailed
collaboration with CWSU ZFW earlier, time windows for FROPA and
better convective/TSRA chances were held close to the previous 12z
D10 DFW TAFs, though it was sped up slightly for the western
airports, while Waco Regional and eastern D10 airports (DAL/GKY)
were delayed by up to an hour. Basically VCTS, potentially strong-
severe to occur between 20z-01z with TEMPO groups with variable
gusts up to/in excess of 40 kts possible and IFR or low MVFR
conditions during a 4-hour window between 21z to 01z, delayed an
hour at DAL/GKY. Current low VFR/high MVFR cigs across the D10
airspace will drop into low MVFR with prospects for IFR conditions
tonight into mid morning Saturday.

Current southerly surface winds between 8 to 18 kts and gusty
winds will quickly veer northerly or northeasterly 15-20 kts with
gusts to 30 kts once FROPA blasts through later this afternoon.
These gusty winds may lay out and weaken for a short while between
09z-13z, before kicking up again to the aforementioned speeds
by/after 15z-16z Saturday. Scattering of lower cigs with
drier/cooler air arriving late Saturday morning will result in
returning VFR conditions with winds backing to the NW 17-22kts
with gusts 30-35 kts.

A surface low and associated strong cold front between KGRK/KILE
and KBWD/KMKN will track E-SE quickly into areas east of I-35/35E
thanks to good support from a very impressive mid level shortwave
trough diving SSE across NW TX/W OK/and the TX/OK Panhandles as
we move into nightfall.
