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...

Heat index values near 105 are expected again this afternoon, so
take precautions to prevent heat related injuries. At the same
time, isolated to perhaps scattered showers and thunderstorms
will be developing this afternoon. Some of these storms could
produce gusty winds, frequent lightning, and brief, heavy
downpours. Overnight, new thunderstorm activity from the north
along a cold front may move into the area by daybreak. Otherwise,
no other hazardous weather is expected at this time.

.DAYS TWO THROUGH SEVEN...Wednesday through Monday...

Thunderstorms will become more widespread into midweek as the cold
front slowly moves South of I-20 briefly and then lifts back
northward.

In addition, the remnant of tropical depression Harvey is over
the Yucatan Peninsula now and will move across the Western Gulf
of Mexico, regaining storm status and then making landfall on the
Texas coastal bend. Harvey is forecast to move northeastward into
our area early this weekend. Preliminarily, widespread rainfall
amounts of two to four inches are expected, with higher amounts
possible. These amounts could increase as the track forecast comes
into better focus.

.SPOTTER INFORMATION STATEMENT...

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

This Hazardous Weather Outlook is for South-Central Texas..

.DAY ONE...Today And Tonight.

Locations generally along and east of Interstate 35 and along the
Rio Grande will see afternoon heat index values of 102 to 107
degrees again today. Prolonged exposure to the heat and exertion
outdoors without proper hydration and other precautionary actions
may result in heat related illness.

.DAYS TWO THROUGH SEVEN...Wednesday through Monday.

Elevated heat index values will continue along and southeast of
the Balcones Escarpment and along the Rio Grande Wednesday, with
peak values ranging from 102 to 107 degrees during the afternoon
hours.

We are monitoring the remnants of what was Tropical Storm Harvey,
currently located across the western Caribbean Sea. Conditions are
favorable for re-development into a tropical cyclone over the next
5 days. There remains considerable uncertainty on where this
system will track through the southwest Gulf of Mexico and what,
if any, impacts occur in South Central Texas. If moisture from
the system makes it up into South Central Texas there will be a
potential for heavy rainfall Friday through Sunday. Check back
frequently through the week for updates.
