Area Forecast Discussion

.SHORT TERM...(Today and tonight)
Issued at 333 AM CST Sun Feb 25 2018

Temperatures out did models yesterday even with fresh snow. Full sun
in the afternoon allowed temperatures to rise into the mid 30s over
southwest Nebraska. High clouds to the west rounding the ridge and
moving across western Nebraska early this morning. They look pretty
dense but should move to the east through the morning with some
clearing in the afternoon especially north. Have gone with highs
around 40. Westerly down slope flow and ridge building east will
aid the warm up.

Tonight clear skies will allow temperatures to radiate out quickly.
Light southwesterly flow will help to keep temperatures from
bottoming out. Lows expected in the single digits along river
valleys and teens elsewhere.

.LONG TERM...(Monday through Saturday)
Issued at 333 AM CST Sun Feb 25 2018

Dry and seasonal conditions are expected the first half of this
week. An upper low will dig south along the west coast and be
centered across southern CA by Tuesday evening. West to southwest
flow aloft will dominate across the central portions of the
country ahead of this feature for the first half of the week. As
mentioned, temperatures will be seasonal with highs in the 40s and
lows in the teens to lower 20s.

The upper low will move northeast toward the central plains
Wednesday. Initially it will weaken as it crosses the Rockies, but
strengthen once again as it moves into the central Missouri
Valley Wednesday night. Models continue to indicate that most of
our immediate area will remain west of the precipitation
associated with the system. Will continue a slight chance across
eastern sections of the area Wednesday and Wednesday night, but as
it stands now this system appears to miss our area. Any shift
west could mean heavier precipitation, so we`ll keep a close eye
on it.

By weeks end a large long wave trough will encompass much of the
western third of the country. Southwest flow aloft on the eastern
periphery of the upper trough will keep conditions seasonal across
our region. Models do indicate the upper trough moves east toward
the central plains next weekend. Models differ on how the upper
trough evolves as it moves east. Weather conditions could be
unsettled next weekend, with at least some potential that a storm
system could evolve as the upper trough crosses the area.


.AVIATION...(For the 18Z TAFS through 18Z Monday afternoon)
Issued at 1139 AM CST Sun Feb 25 2018

Expect few to scattered cloud coverage across the next 24 hours as
high pressure dominates the weather pattern across the country.
Winds will be light from the west or southwest at under 10 KTS.
