.AVIATION...
Much less cumulus today compared to Sat Aftn and as a
result...much less in the way of convection to deal with. Will
watch isolated showers which have just recently developed in the
vicinity of the LFK terminal for the possible addition of a VCSH
or VCTS mention in the 00z TAF cycle but otherwise, should have
prevailing VFR conditions through the night and through the day
Monday. 

Cu field will again begin building near or shortly after 15z on
Mon but no ceilings are expected attm. The 12z NAM output is the
only model suggesting the likelihood of -TSRA in the vicinity of
the TXK/ELD terminals late in the TAF period on Monday so will
choose to leave out any mention of this weather for this cycle but
may need to include a mention for the 06z TAF package if more
model consensus indicates.

Look for light south to southwest winds overnight with speeds less
than 10kts. South to southwest winds will prevail near 6-10kts
areawide beyond 15z Monday.

Hazardous Weather Outlook For WINN County, LA

100 PM CDT Sun Jul 15 2018

 DAY ONE  This Afternoon and Tonight  

Isolated thunderstorms will be possible this afternoon during 
peak heating. Any thunderstorms that develop may produce gusty 
winds to near 25-30 MPH, brief heavy rainfall with amounts up to
one quarter of an inch, and deadly lightning. 

A more critical concern will be the heat with highs in the middle
to upper 90s. The hot temperatures when combined with the relative
humidity will produce heat indices from 105-110 degrees. Therefore,
a Heat Advisory is in effect until 7 PM this evening. Any amount 
of time spent outdoors should include frequent breaks in the shade
and adequate hydration to avoid any heat- related illnesses. Work
should also be done during the morning or early evening hours to 
avoid the hottest part of the day. Clothing should be light 
colored and loose- fitting as to allow your body to cool itself. 

 DAYS TWO THROUGH SEVEN  Monday through Saturday  

Isolated to scattered thunderstorms will be possible each day
Monday through Thursday, mainly across Southeast Oklahoma,
Southwest Arkansas, and Louisiana.

As an upper level ridge builds over the area, rain chances will
diminish and temperatures will gradually climb into the upper 90s
and low 100s by late week. Combined with the humidity, the hot
temperatures may result in heat index values well above 100 
degrees F across the entire Four State Region.

 SPOTTER INFORMATION STATEMENT  

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