.SHORT TERM... /NEW/
/Through Tuesday Night/

...Today and Tonight...

Though longwave ridging continues to dominate upper-level flow
across much of the central and eastern CONUS, a weak inverted
trough currently positioned just west of the lower Mississippi
River Valley will bring one more day of mostly cloudy skies and
low precipitation chances (10-20%). While weak forcing and ample
moisture will generally support convection, a persistent deck of
upper-level clouds across portions of North-Central and Northeast
Texas will likely keep temperatures this afternoon in the mid-90s,
generally just shy of convective temperatures which will be in
the upper 90s for most. Nonetheless, sparse showers, and perhaps a
weak thunderstorm or two are anticipated, primarily in East
Texas, but potentially as far west as the I-35 corridor before
sundown this evening.


...Monday and Tuesday...

As ridging and subsidence strengthen their grip on the region,
highs will climb into the upper-90s/lower-100s. This is in part
due to high PBL moisture content shifting further to the east.
Though the drier air will help us cool off into the 70s (upper 60s
across Central Texas and into the Hill Country) overnight, it
will still be sufficiently humid with high enough afternoon temps
to begin a stretch of heat indices ranging from 105 to 109
degrees. As such, heat headlines will be needed for Monday and
Tuesday, particularly for the urban areas of the DFW metroplex
where overnight lows will still struggle to cool into the upper
70s.

.LONG TERM... /NEW/
/Wednesday through Saturday/

...Wednesday and Thursday...

A strong ridge will continue to be in place, potentially bringing
the hottest temperatures of the year so far during this time
frame. Afternoon high temperatures look to be near or just above
100 degrees for most, with the exception of locations in Central
Texas near the Hill Country where highs will remain in the mid
90s. Though surface moisture will still be relatively low, dew
points will be on the rise, increasing into the upper 60s and low
70s (especially across East Texas) towards the end of the week.
This will bring continued max heat indices of 100-109 degrees
towards the work week`s end.

...Friday and Saturday...

Heading into this next weekend, a strong high pressure originating
from Canada will make an impressive surge southward across much
of the central and eastern CONUS. Unfortunately for us, the vast
majority of this cool air will remain north and east of the
region. Nonetheless, we will still see some impacts from this
system. The cold front on the leading edge of the high will
approach and stall across, or just northeast of the area, bringing
the potential for isolated to scattered thunderstorms (20-40%)
each afternoon beginning on Friday. The increase in cloud cover
and lower heights advected into the southern Great Plains will
also help moderate the heat we`ll experience earlier in the week,
with highs looking to drop into the 90s: near or slightly below
average. The exact timing of this front, convective coverage, and
amount of clouds all remain uncertain as of now, which all have
implications on the exact temperatures to be expected heading into
this upcoming weekend. So stay tuned to the forecast as those
details become more clear in the coming days!

.AVIATION... /NEW/
/18Z TAFs/

A BKN deck of MVFR ceilings continues to scatter out and lift to
the 3-4 kft range (SCT030 to SCT040) by the start of the 18Z TAF
period. There will be a very low chance (10-15%) for a stray
shower or thunderstorm to impact all TAF sites before 00Z this
evening, but probabilities remain too low to include in TAFs at
this time. Otherwise, VFR conditions are expected, with southerly
winds at 10-15 kts decreasing to 5-10 kts after 00Z this evening.
