Update...
issued at 1225 PM CDT Sat may 30 2015

Morning updates were mainly to refine for the sprinkles...also
clouds/clearing from the north...along with tweaks to the wind
forecast. Drier air is working in from the north with decreasing
clouds from north to south. Brisk north winds will gradually
decrease later this afternoon.

Short term...(today through monday)
issued at 319 am CDT Sat may 30 2015

Today

Regional radar showing some returns developing over the northern County Warning Area this
morning within pocket of subtle isentropic upglide...with lift being
aided as well via weak vorticity maximum aloft. Expect any isolated shower
activity though will be brief in nature as subsidence increases through
the morning hours. As for cloud cover...infrared imagery depicting back
edge just north of the County Warning Area. Per latest hrrr/rap13...cloud cover will
probably hang on tight at least through middle morning before gradual
clearing takes place from north to south. Otherwise...relatively cool
conditions today with highs topping out only in the middle/upper 60s.

Tonight through Monday

Surface high pressure ridge moves across the region tonight which
should allow skies to clear. Winds become southeast on Sunday with
high clouds increasing...with only marginally warmer temperatures in the
upper 60s/lower 70s. The models do hint at a very subtle upper
level wave moving out of the northern rockies which could bring
isolated showers to northeast Nebraska Sunday afternoon.

A secondary very subtle wave appears to move off the Front Range
Monday night...which will bring continued chances of mainly isolated
showers to eastern Nebraska...with very limited instability. That
could linger Monday morning...then dry for Monday afternoon. Lowered
previous forecast and kept readings in the upper 60s to lower 70s
given high degree of expected cloud cover.

Long term...(monday night through friday)
issued at 319 am CDT Sat may 30 2015

Yet another weak subtle wave appears to move out of the northern
rockies late Monday night and lingers through Tuesday which could
bring additional showers to the area...and with instability also
returning...should see more potential for thunderstorms by this
time as well. In fact...several more subtle waves will move across
the region through the remainder of the week with the area as the
slightly Flat Ridge remains in place across the plains. Temperatures also
return to slightly above normal with highs mostly in the lower 80s
by Wednesday and beyond.

Issued at 1225 PM CDT Sat may 30 2015

The MVFR ceilings over in the vicinity of the tafs now...so only have
an hour or so before VFR conditions prevail. Brisk north winds
12-16kt with gusts 20-26kt to decrease to 12kts or less after
20z...then light and variable tonight. Winds diminish with clear
skies. Some hint at a few low clouds or patchy fog...but did not
add at this time.
