.DISCUSSION...
ISSUED 235 PM CST Tue Mar 4 2014
Forecast concerns today is the light pcpn Wednesday, another
system for the weekend, and an added minor front on Tuesday.

SHORT TERM...Tonight through Thursday night.
Morning upper air data shows a complex weather system in the
northern plains and Rockies. Upper wave into MT this morning to be
moving to the southeast, with another wave moving through UT. The
entire pattern will be tracking east southeast overnight, somewhat
phased, bringing a developing of overrunning light snow into IA
tonight, then tracking into northern half of IL Wed. The southern
wave appears to have a better chance of development, as it tracks
into KS and OK, which appears to pull energy from the northern
wave. The result will be only light snow for the northern half of
IL with minor amounts, the most being around an inch in the
northern parts of the CWA.

LONG TERM...Friday through Tuesday.
Progressive westerly upper flow begins the extended periods, with
another weak cold front to move through the region Friday night.
Temperatures now have warmed enough that the chance of pcpn has to
now be a mixture of rain/snow. Pcpn amounts though should be light,
as system is relatively weak.

Another weak front on Monday night into Tuesday will bring chance of
rain to region.

.AVIATION...
ISSUED 600 PM CST Tue Mar 4 2014

A clipper system will pass mainly north of the central Illinois
terminals on Wednesday. Predominantly VFR conditions are anticipated
through the 00Z TAF valid time. VFR cigs should develop later
tonight and linger through Wednesday. KPIA & KBMI stand the best
chance of seeing MVFR cigs, but given recent model trends, will
carry low end VFR for now. Can`t rule out a few flurries either
Wednesday, but they should be few and far between. Light winds
tonight will trend easterly around 10 kts on Wednesday.
