.SHORT TERM... /NEW/
/Through Tomorrow/

Radar imagery depicts a broken line of strong to severe
thunderstorms across North and Central Texas, extending from Lamar
County to Bell County at the time of this writing. This activity
will continue to push east as a strong cold front, currently along
a Bonham to DFW to Comanche line continues to surge south and
east. A favorable environment, characterized by dew points in the
60s, steep mid level lapse rates around 7 C/km, MLCAPE upwards of
1500 J/kg, and deep layer shear values upwards of 50-60 knots will
continue to support the threat for severe weather ahead of the
cold front. Large hail and damaging wind gusts will be the main
threats, but a tornado threat cannot be discounted especially with
the discrete cells ahead of the cold front.

The threat for severe weather will come to an end as the colder
airmass spills southward this evening across North Texas and
tonight across Central Texas. Low temperatures will be about 20-25
degrees cooler than this morning, with lows falling into the 40s
region wide. Additional light precipitation will develop mainly
south of the I-20 corridor tonight. Although most precipitation
should fall as light rain, there is a very low potential for a
brief transition to a light rain/sleet mix across portions of the
Big Country and Central Texas after midnight.

Otherwise, a Wind Advisory will remain in effect through tomorrow
morning as sustained post frontal winds of 20-30 MPH and gusts
near 40-45 MPH are expected through Friday morning. Winds should
decrease in speed late Friday afternoon. High temperatures on
Friday will struggle to reach the mid 50s, roughly 15 degrees
cooler than normal for mid March.

.LONG TERM... /Issued 157 PM CDT Thu Mar 16 2023/
Update:

Only minor adjustments were made with this forecast update and the
discussion below remains on track. Cloud cover Friday night will
inhibit some areas from dropping to/below freezing. Areas near
and north of I-20 are still the most likely to experience low
temperatures below freezing each night through the weekend.
Otherwise, low (20-30%) rain chances arrive Monday, with periodic
low rain chances through the rest of the week. Temperatures return
to near or slightly above normal by Wednesday.

Previous Discussion:
/Friday Night through Wednesday/

A period of well below normal temperatures and sporadic low rain
chances will prevail through the early part of next week behind
today's strong cold front. Friday night will be the coldest night
in a while with temperatures likely dropping to near or just below
freezing to the west and north of the Metroplex. Some patchy frost
will also be possible early Saturday morning. An increase in high
cloud cover late Friday night into Saturday will likely prevent
temperatures from falling further, but these clouds will thin out
during the day Saturday and another cold night is expected with
temperatures falling to below freezing along the Red River
Saturday night.

An upstream shortwave will become sheared apart as it spreads into
the Plains on Monday. Prior to this though, modest moisture return
across parts of Central and West Texas will result in an increase
in low cloud cover, mainly across our western counties. As large
scale lift increases Sunday night into Monday, we could see some
light rain develop across the region. Global ensembles have backed
off on this potential to some degree, so we'll generally limit
PoPs to 20-30%. The increased cloud cover will hold high temps
down into the upper 40s and lower 50s for Monday afternoon.

A much stronger system will move into California on Tuesday and
will be responsible for a rapid low level moisture return into the
Plains starting Tuesday morning. This will also support a rapid
warmup through the middle and latter part of next week. Morning
cloud cover will give way to partly sunny skies Tue/Wed afternoons
with temps warming back into the mid/upper 70s by Wednesday. This
system will eventually kick out into the Central Plains late next
week and likely support another severe weather episode in the
Thu/Fri timeframe.

.AVIATION... /NEW/
/00Z TAFs/

Strong convection along and ahead of a cold front will continue to
move to the east and southeast, ending precipitation chances for
the Metroplex terminals through the period. Intermittent periods
of high end MVFR ceilings and low end VFR ceilings can be expected
this evening, and have included a TEMPO group to account for this
potential. As the cold front advances south, convection will
likely reach Waco closer to 01-02Z before exiting around 03-04Z.
Additional light precipitation may develop behind the front across
Central Texas, but confidence in coverage is low so VCSH has been
maintained for Waco.

Strong post-frontal northwest winds around 25 to 30 knots with
gusts near 35 to 40 knots will prevail through Friday morning at
all TAF sites, before falling to around 15 knots late Friday
afternoon.
