Area Forecast Discussion
National Weather Service Lubbock TX
1207 AM CDT Mon Jun 7 2021

.AVIATION...
Thunderstorm activity is exiting the KPVW terminal area as of 05Z
and Lubbock stands between two areas of storms. We expect minimal
impacts for the remainder of these two terminals outside of the
final approach corridor for KLBB 17R. Indications are that these
storms will hold together and affect the KCDS terminal later
tonight for about an hour or so with VFR prevailing thereafter.
Another chance for storms will exist Monday afternoon.

&&

PREV DISCUSSION... /issued 244 PM CDT Sun Jun 6 2021/

SHORT TERM...
Focus this afternoon is on the potential for an MCS to move to the
east/southeast across the forecast this evening and overnight.
Storms currently going up on the Raton Mesa southward toward Clines
Corners with some cumulus bubbling west of Clayton and from south of
Clines Corners southeastward toward Roswell. General movement of
these convective elements is to the south/southeast, but as some
congealing of outflow increases and organization further increases,
a turn to east/southeast is expected. Some potential for additional
development late afternoon to early evening further east into the
western Panhandle and western South Plains per some models, although
low level flow is light and disorganized with no current zone
favored for convective initiation. Given wide range in model
solutions and the disorganized low level flow (at least until the
low level jet develops later tonight), confidence in how widespread
thunderstorms and their duration still relatively low. Will hold
higher precip chances in the chance category at this time.

Looking forward to Monday afternoon and its precip chances, models
are in even more disagreement likely in large part to an upper ridge
building northward over what has been the primary initiation zone of
eastern New Mexico and western South Plains/Panhandle. Secondarily,
low level flow remains a problem with uncertainty after lingering
outflow boundary or not and how far the dryline or surface
confluence is able to shift with potential for veering low level
flow in the western zones underneath the building ridge. These two
features would shift initiation zone eastward toward the I-27
corridor, assuming initiation occurs. The latter is not straight-
forward with the CAM's and hi-res models favoring over the global
models and WRF-NAM. Will take the inherited slight chance and shift
eastward to generally cover the eastern 3/4 of the forecast area for
the afternoon hours.

LONG TERM...
Any storms that develop tomorrow evening will be pushing east of the
FA by midnight tomorrow night. The weather pattern becomes overall
quiet starting Tuesday as the upper high moves over the region. The
overall affect will be mostly dry conditions (minus a possible pop-
up shower or two) and hot temps. Temps near/over 100F are expected
by Tuesday afternoon with highs over 100F possible area wide
Thursday the high remains overhead and thicknesses increase. Models
have finally come into more of an agreement with the high
temporarily weakening by late week as an upper trough across the
northwestern US pushes eastward across the Northern Plains. This
passing upper trough could push a weak front into the region by late
Saturday/early Sunday allowing for some precip under the center of
the high. If some precip does develop it could help lower highs a
few degrees as the upper high continues to build to near 595Dm.
Little change is expected going into early next week as the upper
high looks to remain in place and amplify slightly going into
Monday.
