...18z Aviation Forecast Update...
.SHORT TERM...(Today and tonight)
Issued at 234 AM CDT Thu Jul 12 2018
Temperatures, heat index values, and scattered thunderstorms will
again be the main concerns in this period. In collaboration with
other offices we will be expanding the heat advisory, adding a
few counties and extending the advisory through Saturday.
An upper level high will be centered just north-east of the area
through tonight. Will go fairly close to a persistence forecast
with highs mostly in the mid-upper 90s. High resolution models do
generate some scattered afternoon/early evening convection over
southeast KS and far western/sw MO counties where higher dew
points and resultant higher instability is progged.
A deep afternoon mixed layer may mix down some drier air/dew
points especially over the eastern cwfa so heat index values could
be lowered in some areas. Typically if that happens, the sfc
temperatures tends to over achieve (higher) than forecast in the
dry air. In any case, the revised heat advisory area reflects
where we feel most confident that the heat index will reach
100-105 deg F for the next few days into the weekend with possible
cumulative effects/impacts on those susceptible to hot and humid
weather.
.LONG TERM...(Friday through Wednesday)
Issued at 245 AM CDT Thu Jul 12 2018
Overview: The overall forecast trend looks to be somewhat cooler
with better overall rain chances early next week. We are not
looking at any major frontal passages, so cooler temperatures will
be driven by clouds/tstms rather than a big wholesale air mass
change.
Friday-Monday: The heat advisory will be ongoing early in this
period, but some changes to the overall upper level pattern will
hopefully bring slightly cooler weather early next week as the
upper level ridge is suppressed to the south and southwest by the
southern extent of the mid latitude westerly flow. A weak and
diffuse sfc front will try to move into the area by late Sunday-
Monday-Monday night with increased rain/tstm chances.
Tuesday-Wednesday: Weak sfc high pressure moving into the Midwest
and OH Vly may limit (but not eliminate) rain chances by Tuesday-
Wednesday. Confidence is lower in forecast guidance by this time.

.AVIATION...(For the 18Z TAFS through 18Z Friday afternoon)
Issued at 1123 AM CDT Thu Jul 12 2018
VFR conditions will continue with high pressure in control of the
weather pattern. There could be a couple widely scattered storms
developing this afternoon across southern Missouri. Have mentioned
VCTS and CB for the BBG TAF until 00z. Otherwise fair to mostly
clear skies along with light southerly to southeasterly winds can
be expected.
