...00z Aviation Update...

.SHORT TERM...(This evening through Friday)
Issued at 149 PM CDT Thu Jul 20 2017

Excessive heat continues this afternoon with temps in the middle
to upper 90s and heat indicies from 100-108. Scattered afternoon
cumulus are prevalent across the area. Temps will remain mild
overnight with some locations remaining near 80.

Upper level ridge continues to build over the area on Friday with
high temps similar to Today if not a degree higher. Dry weather
will continue through Friday.

.LONG TERM...(Friday Night through Thursday)
Issued at 149 PM CDT Thu Jul 20 2017

Saturday may end up being the hottest day of the year for most
locations and have trended up a degree or two for highs. Most
locations will see highs approaching 100. The upper level ridge
will be completely over are area and most locations will see
southwesterly winds which will help boost temps. Latest Drought
Monitor now has portions of our area in an abnormally dry category
which also means that the ground is getting drier and more
susceptible to warmer temps.

A front will make a run south late Saturday night and models are
suggesting precip chances will increase Sunday and into Monday.
Temps on Sunday could be a challenge given clouds/precip.
Therefore it is uncertain at this time whether Heat
Advisories/Warnings will be extended into Sunday. If clouds are
less and moisture pools ahead of the front then it would need to
be extended. This will become more clear as we get closer.

Cold front will make it just south of the area early next week
with additional scattered rain chances possible. Long range
forecast indicates hot temps coming back by mid to late next
week.
