Area Forecast Discussion
National Weather Service Hastings NE
628 PM CDT Wed Apr 18 2018

.SHORT TERM...(This evening through Thursday)
Issued at 321 PM CDT Wed Apr 18 2018

Satellite and observations show stratus that continues to stream
into the northeast part of the forecast area this afternoon. The
southwest has a little sunshine, but there are some stratocumulus
across the area. Northwest winds will continue to be breezy this
afternoon.

A surface high to the north will settle into the area tonight. Winds
will gradually decrease during the late afternoon and drop off as
the sun goes down this evening. The skies should gradually clear out
but the northeast will linger longer into the evening. On Thursday,
the surface high moves off to the east and winds will turn to the
south and start to increase during the afternoon.

.LONG TERM...(Thursday night through Wednesday)
Issued at 321 PM CDT Wed Apr 18 2018

There is short wave ridging across the area Thursday night and dry
conditions are expected. An upper level low developing in the
southern Rockies will start to affect the area Friday. Models have a
few differences in the timing of the start of precipitation, but
there are enough similarities that the western part of the forecast
area should have precipitation start during the day, but wait until
evening before spreading to the eastern part of the forecast area.
This system is definitely warmer and expect it to be all rain
showers. The precipitation should continue across the area on
Saturday, finally moving out of the area Saturday night.

Sunday through Monday should be dry and a little warmer as another
short wave ridge moves through the area. Another upper level wave
moves into the area Monday night through Tuesday. This system is a
little weaker and the showers should be a little more hit and miss.
A surface high moves through Wednesday and brings dry and a little
warmer temperatures again.

.AVIATION...(For the 00Z KGRI/KEAR TAFS through 00Z Thursday)
Issued at 609 PM CDT Wed Apr 18 2018

VFR conditions are forecast through the TAF period. Wind speeds
will diminish tonight as the surface gradient relaxes as high
pressure builds south onto the Central Plains. Models suggest
the potential for intermittent low clouds and will need to monitor
in case lower heights materialize. As the surface high center
reaches northern Nebraska by morning, models also suggest the
potential for fog development mainly north of the terminals and
have not included in the TAFs attm. Light and variable winds late
tonight into Thursday will transition easterly in the aftn.
