Short term...(today and tonight)
issued at 217 am CDT Sat Oct 25 2014

Dissipation of fog and cloud trends the primary focus today.
Beyond this attention turns to temperatures.

07z nephanalysis shows weak trough moving through the region.
Ahead of it...low clouds and fog continue...while to the west of
it better mixing with northwest winds and drier air are rapidly
clearing skies. Only caveat to this is band of middle cloud reaching
from Montana/ND down into SD/MN. This will move into the area this
morning.

Cold advection will offset ample sunshine today...with highs
topping out from the upper 50s to middle 60s.

Long term...(sunday through friday)
issued at 217 am CDT Sat Oct 25 2014

Long wave ridging across the region for the weekend...shifts east
as a significant trough that is currently along the Continental U.S. West
Coast moves across The Rockies and into the upper Midwest to start
the week. Initial surge of warm advection and isentropic lift
should help fuel showers and a few thunderstorms from central Minnesota
into WI Sunday night. Best chances look to lie along and north of
the I-94 corridor. A brief dry period looks likely Monday morning
as the main warm advection Wing moves north. But the cold front
will sweep in later Monday and Monday night. Temperatures look to
be quite mild in the warm sector...with highs reaching the lower
70s across Iowa and southern WI.

Trough shifts east Tuesday with the associated surface cold front
also moving through. Temperatures will fall back to near or even
slightly below normal to complete the week. In fact...another
reinforcing surge of cold air looks to invade by Friday...with
highs only in the 40s.

issued at 630 am CDT Sat Oct 25 2014

Call to klse tower this morning indicating more or less shallow
ground fog occurring for the most part with ASOS indicating LIFR
1/4sm fog vv002 conditions. Look for these conditions to continue
through 1330z...then lifting as mixing begins in the lower
boundary layer after sunrise. Otherwise...plan on VFR condition
for the rest of the period at klse and krst as high pressure
builds into the region.
