Area Forecast Discussion

.SHORT TERM...(tonight through Saturday)
Issued at 243 PM CDT WED SEP 28 2016

Quiet weather continues in the short term with the upper low to
our east continuing to spin across the Ohio Valley. The western
edge of the clouds have affected western Iowa today, The big
question is how far west the moisture associated with the clouds
can move west overnight, and whether any clouds would develop from
that. Will mainly have clouds impacting western Iowa, with not
much development across eastern NE.

Another cool night tonight in the 40s and again Thursday night. Highs
Thursday again in the upper 60s, but then lower 70s for Friday and
Saturday. Could see a few more mid/high clouds Saturday, but dry
weather continues with light winds through the period.

.LONG TERM...(Saturday night through Wednesday)
Issued at 243 PM CDT WED SEP 28 2016

Weak ridging across the Plains early in the period. ECMWF still
hints at a weak disturbance possible underneath the ridge Sunday
into Sunday night, but the GFS has backed off off on any precip.
Will maintain slight chance pops that were already in the forecast
but confidence is low. Then southwesterly flow develops aloft,
with breezy southerly surface flow. This should help boost temps
back into the 75-80 range Monday into Tuesday. Rain chances back
into the forecast Monday night into Tuesday, then Tuesday night
into Wednesday as a cold front moves into the area. Cooler
Wednesday behind the front with temps back to normal in the lower
70s.

Issued at 647 PM CDT WED SEP 28 2016

Satellite imagery and obs show moisture around fl040-050 over Iowa
with variable sct-ovc conditions. Low level flow from the
northeast should continue to advect this moisture westward into
eastern Nebraska. For now will mention scattered deck due to the
patchy nature of the clouds forecast by the rap and see how much
the clouds break up after sunset. Some patchy fog possible
Thursday am for an hour or so and included a mention at koma around
12z with light and variable winds.-- End Changed Discussion --
