A wet weather event occurred on the 8th to 10th, with the approach of an upper
level storm system from the southwestern states. Following a strong cold frontal
passage on the 8th, temperatures dropped through the 40s and into the 30s late
in the day. After the frontal passage, Abilene recorded north wind gust to 44 mph.
Showers and thunderstorms developed and became widespread across central and
southern sections of west-central Texas during the overnight hours of the 8th and
9th. The showers and storms developed north across the Big Country on the morning
of the 9th. A number of the storms contained small hail. One of the storms
deposited enough hail to cover the ground, near Wall in Tom Green County.
A cold rain and scattered thunderstorms continued through the afternoon hours.
The air was cold enough for a few snow flakes to be mixed with the rain in parts
of the Concho Valley and Big Country. Daytime temperatures on the 9th ranged from
the upper 30s to mid 40s.
The upper level storm system stalled over New Mexico on the 10th, before lifting
out to the northeast on the 11th. Light rain and drizzle continued on the 10th,
with a few thunderstorms. The rain ended on the 11th and skies cleared, as the
upper system lifted northeast out of the region.
The heaviest rainfall for this event, in the range of 2 to 3 inches with a few
higher amounts, occurred from the eastern parts of the Concho Valley and
Northern Edwards Plateau, across areas of the Heartland and Northwest Hill
Country. Total rainfall amounts between one half inch and 2 inches, occurred
across much of the area southeast of a line from Ozona to Abilene to Haskell.
The lowest rainfall totals varied under one quarter of an inch, across much
of the western Big Country, northwestern Concho Valley, and Crockett County.
A strong warming trend in temperatures followed passage of this system, and
afternoon highs on the 12th reached the lower to mid 80s across most of west-
From the 13th to 17th, a moist flow of air overspread the region from the Gulf
of Mexico, with south to southeast winds. This pattern resulted in considerable
low cloud cover during the late night through early afternoon hours of each day.
Conditions were more humid than usual for the middle of march. Daily high
temperatures during this time were mostly in the 75-80 degree range, with
nighttime lows well-above normal and mostly in the 55-60 degree range. A few

place, and the arrival of a weak cold front, numerous thunderstorms occurred.
Small hail was observed at the Abilene Regional Airport around midday. The
strongest storms occurred from mid-afternoon to late evening, mostly across
southeastern sections of west-central Texas. Severe storms produced golfball
size hail 16 miles west of Roosevelt (in Sutton County), 8 miles south of
Streeter and 2 miles southeast of Fredonia (both in Mason County), and 2 miles
north of Pontotoc (San Saba County).
Locally heavy, but beneficial rainfall occurred with the thunderstorms on the

Country, eastern Concho Valley, and parts of the Northern Edwards Plateau.
This range of rainfall amounts also amounts occurred across much of the
Heartland and Northwest Hill Country. The highest amounts, between 1.5 and 3
