607 AM CDT Wed Jul 18 2018

 DAY ONE  Today and Tonight  

Isolated thunderstorms will be possible this afternoon and
tonight, mainly across Southeast Oklahoma, Southwest Arkansas, and
North Louisiana. Any thunderstorms that develop may produce gusty
winds, brief heavy downpours, and deadly lightning.

Additionally, hot temperatures, when combined with the relative 
humidity, will produce heat index values from 100 to 105 degrees

 DAYS TWO THROUGH SEVEN  Thursday through Tuesday  

As an upper level ridge builds over the area, rain chances will 
diminish and temperatures will gradually climb into the upper 90s 
and lower 100s by late this week through the weekend. When
