Hazardous Weather Outlook For UNION County,AR

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.
