.SHORT TERM... /NEW/
/Through Sunday/

Today`s forecast features the greatest rain chances of any of the
next several days, as a slow-moving easterly wave and increasing
moisture content culminate in scattered afternoon thunderstorm
activity. Convective coverage will tend to be maximized near and
east of the I-35 corridor, but more isolated showers and
thunderstorms are possible farther west as well. Similar to
yesterday, this activity will not be capable of organized severe
hazards, but gusty downburst/outflow winds and brief heavy
downpours can be expected. The increase in cloud cover will keep
temperatures a few degrees cooler than yesterday afternoon`s
highs, but humidity will also be higher with surface dewpoints
unlikely to mix out to the 60s across the eastern half of the
forecast area. For many locations, despite the slightly lower
temperatures, heat index values will actually be a couple of
degrees higher than yesterday due to the increased humidity. No
changes to the ongoing North Texas Heat Advisory were necessary
with this morning`s forecast update, as this product captures the
area most likely to see heat index values climb to 105-107 this
afternoon. Elsewhere, a combination of either thick cloud cover,
lower dewpoints, or anticipated convective activity should hold
heat index values below criteria.

On Sunday, the upper ridge center that will have been positioned
to our east will begin to expand and strengthen, and will shunt
most rain chances south of the CWA while large-scale subsidence
increases. There will still be sufficient moisture available for
a couple of diurnally driven showers across our southeastern
zones, but coverage is unlikely to be more than ~10% or so. With
cloud cover also on the decline, more areas may be capable of
reaching Heat Advisory criteria on Sunday afternoon, and this
product may need to be extended in time and area into parts of
East Texas in subsequent forecasts.

.LONG TERM... /NEW/
/Monday Onward/

Most of the upcoming workweek is shaping up to be hot and dry,
with some of the highest temperatures of the season so far. A
stout 598 dam ridge will become anchored across the Southern
Plains, which will result in increasingly widespread triple-digit
highs through the midweek period. The small bit of good news is
that dewpoints are generally progged to be lower during this time
period, and should mix into the 60s on a daily basis. This will
offset what would otherwise be an oppressive combination of heat
and humidity, although some heat index values near or exceeding
105 can still be expected. Low rain chances return towards the end
of the week and next weekend as the ridge retrogrades and another
slow-moving easterly wave arrives.

.AVIATION... /NEW/
/06z TAFs/

A brief window of possible convective impacts is the main focus
for this set of TAFs, with scattered shower and thunderstorm
activity expected near and east of the airports this afternoon
and evening. For now, will introduce VCTS at DFW/DAl as well as
Waco, with a lower likelihood of thunderstorms to the northwest
near the AFW/FTW TAF sites. Convection may be accompanied by an
organized outflow boundary which could result in a temporary E or
ESE wind shift. Otherwise, VFR skies and southerly winds at 8-12
kts will prevail with some diurnal cumulus and a SCT/BKN cirrus
canopy.
