Area Forecast Discussion
National Weather Service Lincoln IL

.DISCUSSION...
ISSUED 854 PM CST Wed Mar 5 2014

While the persistent band of light snow/flurries over the far
northern section of the forecast area has continued to weaken, it
is still hanging on to some degree. High pressure continues to
build into the forecast area at the surface, but weak upper level
jet forcing/mid level frontogenesis continue to drive the snow.
Tough to say exactly when the snow will stop completely (probably
soon), but it appears the threat of accumulation has ended.

Going forecast is in good shape overnight. Only plan on a few tweaks for
the latest nighttime trends.

.AVIATION...
ISSUED 1147 PM CST Wed Mar 5 2014

High pressure will dominate the weather across the central
Illinois terminals through the 06Z TAF valid time. This should
result in predominantly VFR conditions across the region, although
a few patches of MVFR cigs can`t be ruled out over the next few
hours. Easterly winds AOB 10 kts should prevail as well.
