AREA FORECAST DISCUSSION...UPDATED AVIATION
NATIONAL WEATHER SERVICE ST LOUIS MO
701 AM CDT Wed Oct 22 2014

.SHORT TERM:  (Through Late This Afternoon)
Issued at 429 AM CDT Wed Oct 22 2014

Broad surface ridge extending from the upper Great Lakes into the
Ozarks will bring the FA another sunny and dry autumn day.
Intensification of ridge over the past 24 hours has brought a bit
of cooler air to the region, which should result in afternoon
temps about 5 degrees cooler than those of yesterday.

.LONG TERM:  (Tonight through Tuesday)
Issued at 429 AM CDT Wed Oct 22 2014

There is a chance of rain showers from late tonight through
tomorrow afternoon as a trough swings through the northern US.
Instability still looks very limited across central and
northeastern MO, therefore no thunder is currently forecast.

Warming trend still looks on track for Friday through Sunday due
to an upper ridge building overhead. Sunday looks particularly
warm because surface winds will have turned southerly to
southwesterly around the back side of an elongated surface high.
Another low pressure system will approach the region early next
week, bringing a chance of rain from Monday through Tuesday.
