What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS San Angelo, TX wrote its last area forecast discussion before this severe thunderstorm warning went out at Apr 29, 3:53 PM CDT, 58 minutes earlier.

Area forecast discussion, Apr 29, 3:53 PM CDT, 58 minutes before

Area Forecast Discussion
National Weather Service SAN ANGELO TX
353 PM CDT FRI APR 29 2016

.SHORT TERM...
(Tonight and Tomorrow)

Dryline/Pacific front is making its way east through the forecast
area late this afternoon with mostly clear and dry conditions
moving in behind. Through the remainder of the evening there will
still be a chance of showers and thunderstorms over our extreme
southeastern counties. Dry conditions are on tap for the remainder
of the night and through the day tomorrow. Lows tomorrow will be
in the low to mid 50s across the CWA and afternoon highs Saturday
under mostly sunny skies will be in the mid to upper 70s north on
Interstate 20 and low to mid 80s south of Interstate 20.

15

.LONG TERM...
(Saturday night through Monday)

The cold front mentioned in the short term discussion will
continue its progress southward Saturday night, moving south and
west through the mountains of west Texas during the day Sunday.
This moist, easterly, upslope flow will aid in the development of
showers and thunderstorms from Sunday evening into Monday as an
upper level trough moves northeast out of north central AZ, across
the Four Corners region, and into the central plains region by
Monday morning. The best chance for precipitation for our area
looks to be areas south and west of a Sterling City to Junction
line, so have kept likely PoPs in the forecast for mainly Crockett
County Sunday night. Although a few strong storms are possible,
severe storms are not expected with this precipitation. Cooler
temperatures will prevail Sunday and Monday behind the cold front
with highs Sunday ranging from the upper 60s north of I-20, to the
lower 80s along and south of I-10, with Monday temperatures expected
to only warm up into the 60s across the area. Rain chances will
linger into Monday morning, but should be ending by early
afternoon.

(Tuesday through Friday)
Expect a warming trend with dry weather following rain chances
Monday, as upper level ridging slowly moves in and over the area
from Tuesday through the end of the work week.
