325 am CDT Sat Apr 25 2015

Short term...(today through Monday afternoon)
issued at 323 am CDT Sat Apr 25 2015

Isolated to scattered showers and thunderstorms will likely
continue across the southern County Warning Area through the morning hours as weak
upper level energy wobbles around the northern plains. Due to the
moist easterly flow...stratus currently over the County Warning Area is likely to
stick around through the day...and because of the cloud
cover...temperatures are likely to be cooler...mainly in the 50s
and 60s across the region.

An upper ridge then develops over the region...with a high
amplitude long wave trough setting up further west. The result
appears to be clear and dry conditions across the eastern
County Warning Area...and cloudy with on and off rain showers possible across the
west. It isnt until Monday that the trough begins to move
east...dragging a front across the County Warning Area. Rain chances are possible
along the front...with best chances appearing to be across the
northern County Warning Area...although quantitative precipitation forecast at this point looks fairly light.
Temperatures rise back into the 60s and 70 for Sunday and Monday.

Long term...(monday evening through friday)
issued at 323 am CDT Sat Apr 25 2015

An upper trough will work its way across the region Monday night
bringing some showers. By Tuesday surface high pressure settles in and
an upper ridge begins to shift into the northern plains. This will
keep the weather pattern mostly dry through Friday. Another low
pressure system may move through the Dakotas Friday night and
Saturday. Models differ on the timing and extent of this system
but have some slight chance probability of precipitation in the forecast for now.

Temperatures will rise through the period...especially under the
upper ridge. Highs may top out near 80 by the end of the week
depending on cloud cover.


Aviation...(for the 06z tafs through 06z Saturday night)
issued at 1240 am CDT Sat Apr 25 2015

terminals. Ceilings may break up during the afternoon Saturday. Winds
will generally be out of the east to northeast.
