Short term
Tonight
scattered showers and thunderstorms once again this afternoon will
become isolated early this evening before dissipating with the
loss of surface heating prior to midnight. The disturbance
responsible for this convective weather will shuffle off to the
east overnight. The exiting shortwave may open up the area for
patchy fog overnight where locally heavier amounts of rain have
fallen, but this would likely be short-lived and only in isolated
areas. Otherwise, low pops have been added to the red river
counties for late tonight where a complex of storms may approach
during the Sunday pre-dawn hours.

Long term
Sunday onward
the main concern for Sunday is a low-end potential for remnants
of a convective complex in ks ok to make it southward into north
texas after daybreak. Corfidi vectors suggest this complex will
have a 25-30 kt southward motion, and will also be in an
environment favorable for strong cold pool production. As a
result, will maintain some low rain chances mostly across north
texas in the morning in case this activity is in fact able to
reach this far south. Any remnant outflow from this convection
could also be of concern later in the day for renewed development
during peak heating. In addition, these nuances are preventing
the issuances of a heat advisory at the current time, since
convective outflow cloud cover could reduce high temperatures
Sunday afternoon. However, if it appears the CWA will be
unaffected by convection, a heat advisory may be needed for parts
of the forecast area with some heat indices likely reaching 105.

The heat will peak on Monday as the low-level thermal ridge axis
nudges eastward into the forecast area ahead of a deepening
surface low and slow-moving frontal zone. Veering southwesterly
winds at the surface will complete the recipe for widespread
triple-digit heat, and some areas across our west could exceed
105f temperature readings Monday afternoon. With dewpoints still
in the upper 60s and 70s, most of the area will easily exceed 105
heat index values as well, with some indices even climbing into
the 110-115 range. A heat advisory will almost certainly be needed
for Monday to advertise one of the hottest days of the year thus
far. However, some relief will be on the way towards the middle
of the week, as the upper ridge becomes centered farther west, and
broad northwest flow aloft overspreads the region.

On Tuesday, the aformentioned frontal zone should continue a slow
southward push into southern oklahoma, accompanied by widespread
convection, possibly in the form of an organized complex. This
activity would have a tendency to come southward, possibly
affecting our northern counties during the morning, and setting up
an outflow farther south for additional development in the
afternoon. Convective chances are expected to linger into
Wednesday as well, as the front (likely reinforced by outflow and
differential heating) remains draped through the middle of the
forecast area. Overall, this system should feature some decent
rain chances, especially across north texas through the middle
portion of the week, along with at least some potential for
strong severe storms as well. The environment will be
characterized by large instability and moderate wind shear of
20-30 kts throughout this time period, which will favor a
multicell cluster storm mode with perhaps slightly more organized
segments near the front itself. Details including timing and
placement won't be able to be resolved well in advance, as
development will hinge on mesoscale features and boundaries from
preceding convection.

Some low storm chances will linger through the rest of the
workweek, as the weak frontal zone washes out more and more each
day. Fairly widespread cloud cover should aid in keeping
temperatures near or even slightly below normal through this time
period.

18z tafs
a weak trough lingering overhead will provide just enough ascent
to allow for another round of diurnally driven convection, with
activity being focused mainly along residual mesoscale boundaries
resulting from yesterday's thunderstorms. One such boundary
extends southwestward from a stationary front over ok and is the
source of the isolated storms near the red river. Another boundary
extends from near dfw southwestward to lzz, where additional
storms are beginning to develop. Flow aloft is weak, and indicates
a general storm motion from west to east at 5 kt or less, though
cell movement will likely become more determined by the motion of
outflow boundaries. Due to the isolated nature of the convection,
the feeling is that vcts would suffice in the metroplex tafs at
this time, but radar trends will be monitored for the possibility
of adding any tempo groups. All activity will wane around sunset
with the loss of surface heating.
