.PREV DISCUSSION... /ISSUED 332 AM CDT Wed Jun 3 2020/

SHORT TERM (Today through Thursday)...
The upper level low centered along the Red River continues to track
east while an upper level ridge centered over Chihuahua state of
Mexico expands to the east over Texas. Subsidence under the ridge,
capping warm mid level temperatures, and drier air aloft gradually
take hold. Heating of a sufficient moisture depth allows for showers
and thunderstorms to spread from the Coastal Plains this morning to
the I-35 corridor this afternoon where they dissipate early this
evening. Moisture depth decreases more significantly on Thursday
with showers and thunderstorms only near the immediate Coastal
Plains. The slow warming trend continues with temperatures near
normal today and only slightly above normal on Thursday.

LONG TERM (Thursday Night through Tuesday)...
The upper level ridge will continue to build over Texas during the
second half of the week. This will mean strong subsident flow and dry
weather Thursday night through Saturday night. Temperatures will warm
each day climbing above normal. The latter part of this period will
be complicated by what happens to Tropical Storm Cristobal. The
current NHC forecast track takes it toward LA. On this track any
impacts to South Central Texas will be minimal. The winds across the
eastern half of the CWA will become northerly to northeasterly
Sunday but only 10 to 15 mph. Slight chance POPs will reach our
extreme eastern counties with only minor rainfall totals. However, if
the track moves to the west it will bring more significant impacts
to our CWA. It is important to keep track of the forecast from NHC
since it will influence our forecast. One other impact from Cristobal
may be strong subsident warming Monday and Tuesday when high
temperatures will reach 100 across most of the CWA. Record highs are
possible Tuesday.
