AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ST LOUIS MO
231 AM CDT Mon Jul 21 2014

.SHORT TERM:  (Through Late This Afternoon)
Issued at 221 AM CDT Mon Jul 21 2014

Mercury will rise a few more degrees today compared to yesterday
as influence of the surface ridge across the Ohio River Valley
weakens and is replaced by southerly flow.

.LONG TERM:  (Tonight through Sunday)
Issued at 221 AM CDT Mon Jul 21 2014

Beginning to feel like a broken record here, but didn`t really
make many changes to the forecast. Models continue to be in good
agreement with a few seasonably "hot" days early this week thanks
to the upper level ridge nosing into the Midwest, followed by
cooler temperatures the second half of the week as the flow once
again becomes northwest aloft. The transition will be marked by a
cold front and chance of thunderstorms Tuesday night and Wednesday
across the area.

The front will move back into the CWA by this weekend with chances
of thunderstorms littering the extended forecast as northwest flow
shortwaves interact with this frontal boundary. Temperatures should
slowly return to normal with highs in the middle to upper 80s this
weekend.

.AVIATION:  (For the 06z TAFs through 06z Monday Night)
Issued at 1123 PM CDT Sun Jul 20 2014

High pressure slowly shifts east through the forecast. Southerly
wind pick up just a bit with afternoon cumulus the highlight. Some
morning fog possible at SUS and CPS, but current temp/dew pt
spreads are 5 - 10 degrees more tonight so will leave out.

Specifics for KSTL: VFR with light southerly wind.
