Area Forecast Discussion

.DISCUSSION...

Please see the 00Z aviation discussion below.

.AVIATION...

Thunderstorms this evening should remain east of area terminals,
though outflow boundaries may impact MAF within the next couple of
hours. Away from storms/boundaries, southwesterly winds this
evening will back to the south/southeast after sunset at all but
CNM, with wind speeds remaining elevated/intermittently gusty at
MAF/INK/FST through the remainder of the period. There may be some
MVFR ceilings toward daybreak, though these should remain just
east of MAF/FST, thus VFR conditions are expected to prevail.
Additional storms are possible affecting MAF/FST after 20Z.

.PREV DISCUSSION... /issued 220 PM CDT Thu Jun 18 2020/

DISCUSSION...
Several weak upper level disturbances will ride through and continue
to weaken an upper level ridge that is residing over the forecast
area through Saturday. These disturbances will combine with
strong daytime heating and low and mid level moisture along a
surface trough to produce widely scattered to scattered (mainly
afternoon and evening) thunderstorms through Saturday. The best
chance will be across west Texas, especially Friday evening, as a
boundary/outflow sinks south across the Permian Basin providing
an additional convective focus. A few storms will be severe each
afternoon and evening through Saturday given progged capes in
excess of 2000 j/kg and wind shear of 15 to 30 knots. Temperatures
will remain above normal through the period.

By Sunday the flow aloft is forecast to become northwesterly as an
upper level ridge rebuilds across the southwest United States.
This will push the best chance of thunderstorms further east into
the eastern Permian Basin and Big Bend Sunday as the surface
trough/dryline moves toward those regions.

For much of the next work week a north to northwest flow aloft
regime is expected to reside over the forecast area with much
above normal temperatures anticipated. NBM guidance continues to
be on the low side for precipitation chances but this could change
if more discernible upper level disturbances can be identified
rotating around the upper ridge in later guidance runs. In
addition the potential for low level boundaries approaching from
the north will also need to be monitored that could provide for
another focus for storm development.
