.PREV DISCUSSION... /issued 341 PM CDT Fri Jul 21 2017/

SHORT TERM...
(Tonight and Saturday)

More dry and hot weather is expected the next 24 to 30 hours.  An
upper level high pressure ridge still centered over the Mid
Mississippi Valley continues to keep a sinking upper level airmass
over the area. Daytime heating will form scattered low clouds, but
none are expected to break the cap of stability caused by this high
pressure area aloft. Rain chances of 5 to 10 percent are expected on
Saturday across central and eastern counties, this is more
indicative of more cumulus clouds that will not cause rain than
anything else, but a brief, isolated renegade shower is not
impossible on Saturday afternoon. Models indicate a very hot Friday
afternoon continuing the heat through Saturday with high
temperatures close to or at 100 degrees. Models indicate light to
moderate south or southeast surface winds in daytime hours that will
weaken to less than 10 mph after sunset. Low temperatures Saturday
morning will be mostly in the mid 70s, except in the Big Country
where they are expected to be in the upper 70s.

LONG TERM...
(Saturday night into Friday)

Mainly and and dry conditions are expected into next week.
However, isolated showers and thunderstorms are possible Sunday
and Monday as the upper ridge weakens temporarily. Highs will be
mainly in the mid and upper 90s with lows in the lower to mid 70s.
Lows toward the middle of next week may creep into the upper 70s
north of I-20.
