00Z TAFS - VFR conditions are expected tonight outside of any
convection. Scattered thunderstorms will continue developing across
the Panhandles, and will persist into the early morning hours. There
is a low possibility some patchy MVFR/IFR fog could develop early
Friday morning, but confidence was not high enough to add to TAFs at
this time. Otherwise, winds will remain out of the south at around 10
to 15kts with gusts and low-VFR clouds developing again Friday
afternoon.

Discussion...
For tonight, another round of showers and tstms developing over the
higher terrain in ern NM and srn CO and also near a sfc trof axis
located in that region will head sewd into the fcst area this evening
and tonight. In addition, a weak upper level low pressure system will
track sewd around the ern periphery of an upper level ridge of high
pressure and into our fcst area tonight, and may augment shower and
tstm development. Have raised pops for tonight about 10 percent
across the board all zones based on the above reasoning coupled with
the fact most guidance pop values have increased as well. Since
atmospheric wind fields are disorganized and not very strong, do not
foresee organized clusters of svr storms. However, a few strong to
marginally severe tstms are well within the realm of possibility
this evening.

The minor upper level low pressure system will likely hang around the
srn high plains through Friday and weaken further before either
getting the boot newd or dissipating by Saturday as the upper level
ridge of high pressure moves ewd and a large upper level trof heads
into the wrn states. Slgt chc pops for Friday and Friday night look
plausible at this time.

The upper level flow will become more swrly this weekend as the wrn
states upper level trof begins moving inland and splitting. All major
models are now showing the trof split, with a portion settling just
off the srn CA coast by late Sunday, then moving enewd to just east
of the four corners region by 12Z Tuesday. The combination of broad
sw flow aloft ahead of the upper level trof near srn CA, sufficient
moisture, daytime heating and attendant atmospheric instability, and
close proximity of a sfc trof axis warrants slgt chc to chc pops
Saturday through Monday.

Based on latest medium range models, it now appears this second upper
level low pressure system is progged to track enewd and newd into KS
and NE Tuesday, north of the OK and TX Panhandles. Should this
verify, our forecast area may end up in the dry slot region of this
storm system. As such, have kept pops below mentionable Monday night
and Tuesday in the event models verify. Also retained a dry forecast
for next Wednesday and Thursday as an upper level ridge of high
pressure builds into the area in the wake of the departing upper
level low.
