AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN ANGELO TX
1142 PM CDT SAT MAY 24 2014

.AVIATION...
/06Z TAFS/

Band of showers and thunderstorms extended from Crockett County
northeast across the Concho Valley and Big Country at 11 PM. NAM and
GFS models indicate the showers and thunderstorms to continue the
next several hours and may continue through the day, with at least
light showers, for KABI. Kept thunder in for KSJT until 10Z and 12Z
for KABI.  MVFR stratus has developed over much of the CWA and this
should lift to VFR in the early afternoon. Similar shower and
thunderstorm setup for Sunday, with another round of scattered
thunderstorms developing in the afternoon. KABI and KSJT have the
best chance of rain...should occasionally see thunderstorms mid
afternoon into the evening hours.

&&

.PREV DISCUSSION... /ISSUED 1007 PM CDT SAT MAY 24 2014/
.UPDATE...
Update for severe thunderstorm watch 184 until 4 AM CDT for Sutton,
Crockett, and Schleicher counties. Also updated overnight
temperatures and adjusted pops higher for current radar trends.

&&

.DISCUSSION...
Thunderstorm outflow boundary has pushed south to Ozona to Eldorado
line at 10 PM. Areas to the south of the boundary, in the warmer
sector, are the most unstable, and a severe thunderstorm watch has
been issued until 4 AM for southwest sections of West Central Texas.

.PREV DISCUSSION... /ISSUED 625 PM CDT SAT MAY 24 2014/
.AVIATION...
/00Z TAFS/

Strong to Severe thunderstorms were developing along and north of
an thunderstorm outflow boundary extending from Big Lake to San
Angelo to near Cross Plains at 23Z.

KSJT have the best potential for storms this evening, some of which
could produce large hail, damaging winds and even tornadoes. Severe
storms to the southwest could follow outflow boundary northeast, and
affect KSJT, mainly after 1Z. Keeping VCTS at KABI through the TAF
period, and KSJT tonight and late Sunday afternoon.

MVFR stratus redevelops after midnight at all sites, rising to
VFR 18-19Z Sunday.

&&

.PREV DISCUSSION... /ISSUED 339 PM CDT SAT MAY 24 2014/

.SHORT TERM...
The main concern in the next 24 hours is the potential for severe
thunderstorms and locally heavy rainfall. Currently, a complex of
thunderstorms is moving across the Big Country. These thunderstorms
will have the potential to produce hail, strong damaging winds, and
locally heavy rainfall. An outflow boundary is located along a Water
Valley...to Big Lake...to McCamey line, and is showing signs of
slowing down. Additional convection is firing across West Texas, in
a very unstable atmosphere. This convection will have the potential
to move into mainly our western counties later this afternoon and
this evening, and a Tornado Watch is in effect for these areas
through 10 PM. Although large hail, damaging winds, and lightning
look to be the main threats, isolated tornadoes will be possible,
especially during the early evening hours. We have increased PoPs
across much of the area, ranging from likely west to low end chance
across the southeast counties. Several models indicate another
shortwave trough moving into West Texas early Sunday morning,
initiating additional convection, then eventually moving it into at
least the western half  of our area. Likely PoPs were continued
across the western half of the region, with higher PoPs shifting
east across the area during the morning hours. Given all of the
mesoscale boundaries currently across the area, a lot of uncertainty
remains on the exact placement and timing of these heavy rain
events.

Given the above mentioned factors, a Flash Flood Watch has been
issued for all of the Big Country and Concho Valley. An additional 1
to 3 inches...with some higher amounts...will be possible this
evening through Sunday evening. The main areas of concern are urban
areas and low lying areas, including low water crossing.

.LONG TERM...
/Sunday Night through Tuesday/
An active weather pattern is in store with a chance of showers and
thunderstorms with heavy rainfall likely and a few severe storms are
possible. Currently, a strong upper level low was located near the
Four Corners region(centered along the Arizona/New Mexico state
line). The upper level low will move slowly east across the southern
Rockies Sunday and then into the southern Plains early next week.
The models are pretty consistent on the track of the upper low. All
the models are still very wet across much of West Central Texas. The
ingredients for heavy rainfall include: lots of moisture(PWATs of
1.2 to 1.6 inches), low level southerly flow and convergence (850 MB
winds 35 to 45 knots), and significant diffluence at 250 MB.
Rainfall amounts of 1 to 3 inches are looking pretty good across
much of the area with locally higher amounts possible. Have a Flash
Flood Watch going until 7 PM Sunday. The Flash Flood Watch may have
to be extended possibly into Monday as thunderstorm complexes(MCS
activity) will continue. In addition, severe weather may be possible
Monday, especially during the afternoon and evening. The combination
of good instability(MLCAPES 1500 to 2000 J/KG) and bulk 0-6KM shear
values of 35 to 40 knots will yield a few severe storms. The main
hazards will be large hail...damaging winds and dangerous cloud to
ground lightning.

/Wednesday through Saturday/
A quieter weather pattern for middle to late next week. The
combination of abundant low level moisture and weak upper level
northwest flow may develop isolated afternoon and evening showers
and thunderstorms. However, will keep the forecast dry for now.
Expect warmer temperatures, with highs in the upper 80s to lower 90s
and lows in the 60s.
