AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
600 AM CDT Tue Apr 15 2014

...Update to Aviation...

.SHORT TERM...(Today and Tonight)
Issued at 305 AM CDT TUE APR 15 2014

Unseasonably cold temperatures and a clear sky prevailed across
the region early Tuesday morning providing ideal conditions for
viewing the lunar eclipse. An axis of surface high pressure shifting
eastward from the Plains will build over the Ozarks today
providing plenty of sunshine and light winds. This will result in
milder but still relatively cool temperatures.

The surface high will shift to the east tonight allowing a
southerly wind to develop especially from southeastern Kansas into
central Missouri. Winds will remain light much of the night
across south central Missouri and the eastern Ozarks which will
allow for better raditional cooling and colder temperatures. A
Frost Advisory will be issued for portions of south central
Missouri and eastern Ozarks late tonight.

.LONG TERM...(Wednesday through Monday)
Issued at 305 AM CDT TUE APR 15 2014

The southerly flow will increase Wednesday as the surface pressure
gradient strengthens ahead of a front developing over the Plains.
This along with plenty of sunshine will push temperatures toward
normal mid April levels.

A shortwave trough will track eastward across the Rockies into the
Plains Thursday as the associated front sags southeastward.
Clouds will be on the increase Thursday with some light rain
developing from the west late in the day. Moisture quality will be
lacking with this system but expect areas of light rain to develop
across the region Thursday night. The shortwave and associated
front will move off to the east on Friday with any lingering rain
ending in the morning at most locations.

Upper level ridging will result in warmer temperatures again on
Saturday. However the next upper level trough within the
progressive upper pattern will arrive Sunday. Moisture transport
into this system again looks marginal but scattered showers are
expected Sunday into Sunday night.
