Area Forecast Discussion
National Weather Service North Platte NE
345 PM CDT Wed Mar 29 2017

.SHORT TERM...(This evening through Thursday)
Issued at 344 PM CDT Wed Mar 29 2017

The wrap-around rain and drizzle across Ncntl and Swrn Neb should 
slowly move east tonight. The forecast uses the HRRR models and RAP 
model. This rain is associated with lower level moisture and support 
from the upper low across KS. 

Most of the short range models show fog forming across the Sandhills 
tonight. The RAP model indicates dry air moving in at the 850-500mb 
layer and this would promote radiational cooling given the clearing 
skies and light winds that are expected to develop tonight. Areas 
east of highway 83 remain in the wrap-around clouds overnight. 
Clearing is expected from west to east Thursday afternoon across the 
Ncntl Neb.

The forecast uses blended guidance plus bias correction. The wet 
ground appears to limit lows tonight to a few degrees above the 
straight guidance numbers. Highs Thursday rise into the upper 40s 
east to around 60 west where mostly sunny skies are expected. 

.LONG TERM...(Thursday night through Wednesday)
Issued at 344 PM CDT Wed Mar 29 2017

Friday will be a transition day in between systems, as upper level 
ridging briefly builds over the area ahead of the next system that 
will dig southeast to near the four corners by Friday evening. By 
Friday afternoon clouds will be on the increase, with rain likely 
developing across portions of the Panhandle and southwest Nebraska 
Friday night. The center of the upper level low pressure system will 
very slowly meander it's way into northern New Mexico Saturday. 
Ahead of the system deep southerly flow aloft will draw moisture 
northward, with rain once again expected through Saturday from the 
western half of Nebraska, southward through Oklahoma and Texas. 

Sunday could see a lingering shower or two as the system moves into 
the plains from New Mexico and weakens. There is yet another system 
that arrives Tuesday into Wednesday, this too appears quite vigorous 
with more rain and perhaps some wet snow. All in all beneficial 
moisture will continue to accumulate the next several days.

.AVIATION...(For the 18Z TAFS through 18Z Thursday afternoon)
Issued at 1233 PM CDT Wed Mar 29 2017

Showers will remain in the vicinity of KLBF, KBBW and KONL 
through late this afternoon, but thereafter ceilings will 
gradually lift into the evening. Dryness in the mid levels may 
promote the development of fog at KVTN and other north central 
Nebraska terminals overnight as winds go light, but fog should be
absent across southwest Nebraska. Overall forecast confidence is
good due to strong model agreement.
