.SHORT TERM...(Today and tonight)
Issued at 350 AM CST Sat Feb 25 2017

Patches of arctic fog have formed across the Wrn Sandhills this
morning. Cameras from NDOR suggests the fog forms and dissipates vs
forming a solid deck. The RAP and HRRR models suggest the fog will
dissipate by mid morning with modest mixing.

H850mb temperatures rise a few degrees today but still remain below
0C. A check on the GFS high cloud procedure suggests a continuation
of cirrus with solid moisture in the 500-300mb layer. High
temperatures today have been marked down a few degrees below the

Tonight...another piece of Pacific high pressure will build into Wrn
Neb. This in combination with snow cover...cirrus indicated in the
GFS and very low precipitable water (less than 0.15 inches) would
support lows in the single digits to zero across the Sandhills.
Winds tonight are a bit stronger suggesting less radiational cooling
and no fog potential.

.LONG TERM...(Sunday through Friday)
Issued at 350 AM CST Sat Feb 25 2017

Temperatures remain cool and below normal through
Thursday...temperatures warm back into the mid 40s to 50s Friday.
Did lower temperatures a bit on Monday to account for fresh snow
pack across the northern and eastern part of the forecast area,
where greatest snow amounts were seen. Main forecast concern this
period is the potential for precipitation early Tuesday morning as a
weak shortwave moves through. At this time it looks like the
precipitation will mostly be in the form of light snow. The rest of
the forecast period will remain dry.
