.SHORT TERM... /NEW/
/Tonight through Saturday Night/
Relatively cool and cloudy conditions prevail across much of North
and Central Texas this evening with light northerly winds and
temperatures in the 60s. Winds above the surface are from the
southeast as the cool frontal layer extends up to about 850 mb.
Later tonight, strengthening east-southeast winds above the
surface will lead to increasing warm moist advection and the
development of widespread showers. This activity should start to
increase in coverage well after midnight when strong isentropic
ascent becomes maximized along and north of the I-20 corridor.
Steep mid level lapse rates will initially support some elevated
thunderstorms with a sub-severe hail threat, but this activity
will wane through the late morning hours as the atmosphere becomes
increasingly moist. Locally heavy rainfall may result in some
minor flooding issues, especially in urban areas.
Later Saturday morning into the afternoon, widespread showers and
embedded thunderstorms will move across the region aided by weak
ascent from a passing disturbance. While most of the activity will
pose nothing more than a lightning/heavy rain threat, there will
be a small portion of our southern counties that may get into a
better warm sector through the afternoon. There could be a few
stronger storms south of a Waco to Palestine line during this
time. In addition, rainfall rates may become most efficient in
this area where PW`s approach 1.8" through the afternoon.
Widespread rainfall amounts of 1 to 3 inches will be possible with
a few locations (~10%) receiving 4+" of rain through Saturday
night.
All of this activity will move east late Saturday night with
rainfall tapering off from west to east and another cool night
expected. Temperatures will drop into the upper 40s for early
Sunday morning.

.LONG TERM... /Issued 315 PM CDT Fri Apr 19 2024/
/Sunday Through Next Friday/
The weather across North Central Texas will trend a lot more
favorable on Sunday as precipitation clears to the east, mainly
before daybreak. Clearing from north to south will lag the
precipitation clearing by several hours, but we do have confidence
that skies will range from mostly clear in the north to partly
cloudy in the south by early to mid afternoon. North winds will be
a bit breezy, but the previous rain should forgo much wildfire
concern. Highs will generally only range from 60 to 65 degrees,
which is at least 10 degrees below average for the date. The theme
of cooler than average conditions will continue Sunday night into
Monday with lows at daybreak Monday mainly in the 40s with highs
Monday afternoon mainly in the upper 60s to lower 70s under partly
cloudy to mostly clear skies.
Temperatures will trend back to average on Monday night into
Tuesday as surface high pressure quickly exits to the east and
southerly low level flow commences. The warming trend will
continue through the midweek with lows in the mid 60s and highs at
least around 80 degrees by Wednesday night into Thursday. Current
long range blended model guidance suggests this warming trend will
continue into at least Friday. A weak disturbance passing well to
the north may get some isolated to widely scattered showers
(cannot rule out a few thunderstorms) going in the warm air
advection regime starting Tuesday night and going through
Thursday. Obviously clouds will be increasing over this time range
as well. NWP guidance still is lacking a strong consensus in
specifics of what will transpire across the forecast area starting
Thursday and going into the weekend as a parade of disturbances
push east from the Western CONUS starting toward the middle of
next week. The loose consensus is that one of these disturbances
will significantly brush north Texas by Friday, although it is
possible tangible impacts could begin a day earlier (and also last
well into the weekend). Needless to say, some severe weather
and/or heavy rain threat could manifest by the end of next week,
although any further details than this will likely have to wait
for better NWP consensus to be reached. SHV / 50

.AVIATION... /NEW/
/00Z TAFs/
Conditions will continue to deteriorate through the late evening
hours with MVFR cigs spreading north across the region at this
hour. These will continue to lower to IFR later tonight with the
development of showers and thunderstorms becoming more likely by
early Saturday morning. Widespread rainfall/thunderstorms are
expected for much of Saturday along with IFR conditions. This
activity should begin to move east of the D10 airspace by late
Saturday evening.
