AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ST LOUIS MO
224 AM CDT Thu Mar 26 2015

.SYNOPSIS:
Issued at 216 AM CDT Thu Mar 26 2015

Light rain will continue to move east and be exiting the CWA this
morning. Threat of flash flooding has ended and will be canceling
the watch early with the forecast this morning. Temperatures
continue to drop through the 40s with steady cold advection, but
clearing and some welcome sunshine should help this afternoon.

.SHORT TERM: (Through Saturday)
Issued at 216 AM CDT Thu Mar 26 2015

A pattern more indicative of winter takes hold across the center and
eastern CONUS to end the work week and begin the weekend.
Temperatures will remain below normal through Saturday as deep
longwave trof digs all the way south to the Gulf Coast. Several
shortwaves rotating through on northwest flow aloft will provide
chances of some light precipitation. The first chance tonight into
Friday morning appears to stay mainly west of the CWA, but for
consistency with neighboring offices have included some slight
chance POPs across central Missouri. The second shortwave, appears
to have a little more "juice" with it and have increased POPs for
the western CWA Friday night and Saturday morning. Atmosphere is
cold enough that some snow may fly in the sky, but accumulation
should remain limited thanks to warm ground temperatures. You know,
my Uncle Carl always told me that it always snows one last time
every spring on the budding/blooming forsythia (bush with yellow
flowers in the spring), and to this day that rule of thumb has held
true. So, to keep tradition alive, I regrettably have a mention of
snow in the forecast. Lets hope it is the last time this spring!

CVKING

.LONG TERM: (Sunday through Wednesday)
Issued at 216 AM CDT Thu Mar 26 2015

Temperatures generally warm during the extended as upper levels
go zonal across the CONUS next week. Appears that two weak cold
fronts will bring a chance of rain Sunday and Sunday night and
showers and thunderstorms to the area Wednesday/Wednesday night.
