...New Short Term...

.SHORT TERM... /NEW/
Update:
Convection overnight could not overcome the stable air currently
in place across North and Central Texas. We could still see
additional showers and storms later today associated with the
exiting shortwave. The best storm chances will remain near the Red
River.

We will go ahead and cancel the Flood Watch that was in effect
until 7 AM and leave the remainder of the forecast largely
unchanged outside of some minor hourly grid adjustments.

Previous Discussion:
/Tonight through Friday Night/

After a brief reprieve from showers and thunderstorms this
evening, additional showers and a few thunderstorms will continue
to move in from the west overnight. This activity will be moving
into relatively stable air currently across North and Central
Texas. Therefore, we don`t anticipate much in the way of severe
weather, but we can`t rule out a strong storm with gusty winds or
small hail. We will maintain the Flood Watch through the night,
but most of the rain associated with the activity overnight will
likely not cause too many additional flooding problems.

Extensive clouds and patchy fog overnight will keep temperatures
generally in the 60s. The only exception will be across the far
west where clouds will partially clear, allowing for lows to fall
into the upper 50s.

Friday will be a much less active day than today with most
locations not seeing any additional rainfall. However, we will
maintain some low chance PoPs (20%-40%) generally north of I-20
due to the passage of a trailing piece of shortwave energy.

Although clouds will linger for part of the day Friday, there
will still be some afternoon sun, allowing temperatures to warm
into the upper 70s to lower 80s. Temperatures will steadily fall
after sunset Friday under a mostly clear sky. The clearing sky and
wet ground will result in patchy fog, especially overnight through
Saturday morning.

.LONG TERM... /Issued 359 AM CDT Fri May 17 2024/
/This Weekend Through Next Week/

After our period of unsettled weather, a rain-free interlude will
begin this weekend with temperatures and humidity steadily
increasing into early next week. A cold front may approach during
the middle of the upcoming week, increasing cloud cover and
reintroducing rain chances, but seasonally warm temperatures will
prevail.

The storm system that doused the region yesterday will finally
pass east of our meridian Friday night, being replaced by ridging
aloft. Positive mid-level height anomalies will prevail into next
week, pushing daytime temperatures into the 90s. Combined with
rich Gulf moisture, this weekend will remind us that the Texas
summer is right around the corner. The heat and humidity will
culminate on Tuesday when heat index values will top 100 in many
locations.

The rather strong early-season subtropical ridging over Mexico
that will nose into the Lone Star State will keep the spring
storm tracks to our north. However, a midweek shortwave emerging
from the Rockies and transiting the Central Plains will manage to
deamplify the ridge a bit, potentially sending a cold front in our
direction. There is little agreement as to how far equatorward
the boundary will penetrate, the eventual evolution perhaps
governed by its associated convection. In any event, its proximity
should by sufficient to return rain/storm chances to the
forecast. However, the current forecast will maintain the
plurality of southerly winds and seasonally warm temperatures
throughout the upcoming workweek.

.AVIATION... /Issued 1200 AM CDT Fri May 17 2024/
/06Z TAFs/

Ceiling heights will be a challenge to forecast overnight since
low level flow is weak and numerous small scale boundaries remain
from earlier convection. The decoupled boundary layer is moist so
we do anticipate deteriorating flying conditions overnight with
weak surface winds. Guidance is in good agreement that VFR
ceilings late this evening will lower to MVFR overnight, falling
below 1000 ft briefly towards sunrise. Visibilities will also fall
towards sunrise in patchy fog. Extensive cloud cover should keep
visibilities above 1 mile. Ceilings and visibilities will improve
by mid-morning Friday, with all TAF sites seeing VFR conditions
by midday.

A few showers and storms will approach the TAF sites from the
west overnight, but stable air in place across the region will
keep coverage too limited to mention in this TAF package. Any
showers or storms Friday will likely stay north of the Metroplex
terminals, closer to the best large scale lift associated with
passing shortwave energy.

A north to northwest wind will prevail through Friday afternoon at
speeds generally less than 10 knots.
