SHORT TERM.../Tonight through Sunday Night/

Broad UA ridging centered across east TX and LA has resulted in
rather dry and hot conditions today, thus evident by this aftn
temps in the 90s and subsequently heat indices ranging from 94-105
degrees. The Shreveport Regional airport reached the 100 degree
mark yesterday aftn, and would not be surprised if happens again
today. As such, be sure to take the necessary precautions to stay
cool if outdoors by drinking plenty of water, wearing light-
colored and light-weighted clothing and taking frequent breaks in
the shade. A mild night is in store with overnight temps only
falling into the 70s. Concurrently the center of the UA ridge will
commence to shift westward to across east and southeast TX and
promote slight southwest flow aloft. A shortwave trough
progressing east-northeast across the Northern Plains will send
down a cold front that will settle in across the Central Plains.
The result will be scattered showers and thunderstorms that will
affect OK and with the flow aloft, could near southeast OK
tomorrow morning. No hazardous weather is expected. Persistence
will be the rule in regards to daytime temps tomorrow /upper 90s
to 100 degree temps/ as the influence of the nearby UA ridge
maintains its grip across the FA.

Lingering frontal boundary and embedded impulses within the flow
aloft may once again aid in generating scattered showers and
thunderstorm across OK tomorrow night, and could once again near
southeast OK and perhaps southwest AR /due to the ensuing southwest
flow aloft/. /29/

LONG TERM.../Monday through Saturday/

Upper ridge to continue retrograding wwd early in the upcoming work
week, as a TUTT moving along the nrn Gulf coast begins to intrude
from the e. This will provide some palpable relief from the weekend
heat and also bring some decent rain chances to us, especially for
areas s of I-20, through Wednesday. If we are able to see
widespread, diurnally enhanced convection as the low passes /as the
Euro in particular is indicating/, high rainfall rates possibly
leading to isold flooding, will be possible.

Another TUTT right on the heels of the early-week TUTT will fully
force the upper ridge well n of us and bring continued heat relief,
with blended output indicating very near-normal temps through the
end of the pd. In addition, chances for convection associated with
the passing disturbance will carry through the remainder of the
fcst. /12/

This Hazardous Weather Outlook is for portions of south central
Arkansas, southwest Arkansas, north central Louisiana, northwest
Louisiana, southeast Oklahoma, east Texas and northeast Texas.

.DAY ONE...Today and Tonight...

Very hot, humid, and dry conditions are expected again areawide
this afternoon, as temperatures climb into the upper 90s to near
100 degrees. When combined with the humidity, afternoon heat
indices will range from 100 to 105 degrees. If you must be
outside, remember to take frequent breaks and drink plenty of
water.

.DAYS TWO THROUGH SEVEN...Sunday through Friday...

Very hot, humid, and dry conditions will continue Sunday and
Monday, with temperatures climbing into the mid 90s to near 100
degrees each day. When combined with the humidity, afternoon heat
indices will range from 100 to 105 degrees. However, scattered
showers and thunderstorms will increase by Tuesday and Wednesday
with an approaching upper level disturbance from the east, which
will result in slightly cooler temperatures and the potential for
much needed rainfall. While this disturbance will exit the region
into Central Texas Wednesday afternoon, isolated to scattered
showers and thunderstorms will remain possible Thursday and
Friday especially over East Texas and North Louisiana as
additional upper level disturbances move into the region from the
east.

.SPOTTER INFORMATION STATEMENT...

Activation of emergency managers, amateur radio operators, and
storm spotters, will not be needed through tonight.
