.SHORT TERM...(This evening through Friday)
Issued at 334 PM CST Thu Dec 14 2017
Precipitation Ending...The rain showers/sprinkles will gradually 
come to an end from northwest to southeast later this afternoon 
into early this evening as the upper trough exits the area. Can 
not rule out a few wet snowflakes before the precipitation ends, 
but certainly not a big deal. 
Temperatures...
Tonight...The clouds will gradually scatter out some later
this evening making for a mostly clear night with decreasing
winds. Consequently, expect good radiational cooling tonight
behind the departing storm system and lows ranging from the upper
teens to lower 20s. Decided to go with the cooler model guidance
for tonight's lows.
Friday...We expect upper level ridging across the rockies and 
high plains with warmer air moving into our area aloft and at the
surface with downsloping west southwesterly surface winds.
Therefore we expect a nice warm up on Friday from those cold
morning lows to highs around 50 east to the mid and upper 50s
southwestern zones.
.LONG TERM...(Friday night through Thursday)
Issued at 334 PM CST Thu Dec 14 2017
Saturday...We will start to see the beginning of a pattern change
with an upper trough over the western states on Saturday. We will
see a cold front track through our forecast area late in the day 
or Saturday night allowing most areas to squeak out a nice day
with highs in the 50s. If the cold air arrives early these highs
might be too warm. It is expected to be a dry frontal passage.
Sunday...It appears that any moisture with this next system will
split us with some rain chances southeast of our forecast area and
snow chances to the northwest. Models have been trending more this
way. Therefore, we are calling for a cool but dry day. Highs will
should still be near normal in the upper 30s to lower 40s.
Monday-Wednesday...We see a return to weak ridging over the
western states on Monday that transitions east into the plains on
Wednesday making for a dry and warm few days with highs back into
the upper 40s and 50s.
Thursday...This is really when the entire larger upper pattern
will likely begin to change with colder air just starting to move
in. We expect to see a deepening trough across the western and
central states that should become a more persistent feature. For 
this reason, the 8 to 14 day forecast is calling for colder than 
normal temperatures, which can get down right brutal this time of 
year and at least an increased chance of storm systems on the 
plains.

VFR conditions will prevail through the period. That said...plenty
of lower clouds near 5KFT is visible in Satellite imagery and 
being observed at KGRI and sites just north of the terminals at 
this time. Expect BKN cloud cover to spread across the both
terminals through early Friday morning...with CIGS improving to 
above 12Kft during the morning hours. Overnight...northwesterly 
winds will gradually shift and become southwesterly by midday
Friday as a surface trough passes to the northwest.
