.PREV DISCUSSION... /Issued 337 PM CDT THU JUL 21 2016/

DISCUSSION...
Hot and humid weather continues under expansive upper ridge. Heat
index values between 105 and 110 have been observed again and only
marginally lower readings expected Friday as dew points mix out a
little more, but actual temps rise above 100 in parts of eastern
OK. Heat advisory in effect Friday will be expanded to cover all
of the forecast area, though northwest AR counties may fall just
short. Any thunderstorm potential very limited through Saturday.

Ridge still expected to break down and retrograde just enough
early next week to allow a weak cold front to surge close enough
to raise the overall probability of storms next week, especially
Mon/Tue when flow aloft becomes more northwesterly. This will also
provide a limited amount of relief from the heat.
