1126 AM CDT Sun Jul 23 2017

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

.DAY ONE...This Afternoon and Tonight...

The upper low over the Gulf coast remains in play today with
another good sea breeze push inland. Scattered showers and
thunderstorms over much the area this afternoon will be capable
of producing gusty winds to 30 MPH, deadly lightning and brief
heavy rainfall. An isolated storm may produce damaging winds as
storms develop on outflow boundaries from previous storms.

.DAYS TWO THROUGH SEVEN...Monday through Saturday...

The pattern aloft that has brought this recent chance for
rainfall will linger to some extent into the work week as another
upper disturbance over Northern Mississippi drifts our way in the
Tropical Easterlies for early in the work week. Rain chances will
start to taper off as the upper ridge returns, suppressing the
chance for rain in the Four State Area mid to late week with
daytime highs climbing back into the middle to upper nineties.
This will likely mean more heat advisories for the late week.

.SPOTTER INFORMATION STATEMENT...

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

produce heat indices between 105 and 110 degrees. Please exercise

the possibility of heat related illness.

There is also a Marginal Risk of severe thunderstorms today and

After slightly cooler conditions on Monday courtesy of clouds and
precipitation chances, very warm and humid conditions will return to
the area. High temperatures are expected to climb well into the 90s
