...18Z AVIATION UPDATE...
.SHORT TERM...(Today and Tonight)
It was a warm and humid night over extreme southeast Kansas and
the Missouri Ozarks. Temperatures struggled to cool out of the
middle 70s, under mostly clear skies and light winds.
A frontal boundary had stalled across southern Missouri overnight,
helping to collect and pool humidity. Dew points were running in
the middle 70s.
For today, a summertime high pressure system will expand into the
region from the southwest, setting the stage for some oppressive
Look for highs to warm into the low to mid 90s in most locations
today. Heat indices will range from 103 to 109 over areas along
and west of a line from Cassville to Warsaw. Therefore a Heat

Another humid night is expected headed into early Saturday
morning. Lows will only fall into the low to mid 70s. We could
observe a cluster of thunderstorms approach the Ozarks from the
northwest tonight. Will need to monitor the Nebraska and Kansas

through at least Tuesday.
By Wednesday, the GFS suggests that the summer high will begin to
break down, allowing a surface front to approach from the north.
This mid week frontal system will be our next organized chances
The GFS has been persistent with strengthening the summer high
over the western conus toward late next week. This would bring
cooler temperatures and increased chances for scattered

VFR conditions will prevail for the TAF period. Some high clouds
will traverse the area this afternoon. Very small chance of a
shower or storm this afternoon and evening but confidence and

overnight at BBG. Winds will remain light throughout the period.
