.SHORT TERM...(Today and Tonight)
Cloud cover and precipitation was breaking out over eastern Kansas
and northern Missouri early this morning. This area was on the
northeast periphery of a summertime high that failed to expand
into the Ozarks like the models were suggesting.
Therefore, our heat headlines could be in jeopardy of not
verifying if convective trends continue to increase through the morning

For tonight, thunderstorms can not be ruled out as there are some
convective signals present, particularly in central Missouri. Look
for overnight lows struggling to cool out of the mid to upper 70s.
.LONG TERM...(Monday through Saturday)
We still think the summer high will finally expand over southern

of our next cold front. This feature will trigger our next decent
chances for showers and thunderstorms Wednesday into Thursday.
Temperatures will cool back into the 80s for Thursday and Friday.

the western United States for next weekend. Therefore the Ozarks
will experience near normal or slightly below normal temperatures,
with low chances for showers and thunderstorms next Saturday and

Issued at 645 AM CDT SUN JUL 26 2015
For the KSGF/KJLN/KBBG tafs: VFR conditions are expected. Similar
conditions to the past 24 hours are expected with a warm front
north of the area. An unstable air mass is in place and
thunderstorms are possible but it`s hard to determine timing and
placement. Overall better chances will be north and northeast of
the taf sites.
