Today through sunday:
high temperatures today will be about 10f to 15f cooler as a cold
front and northwesterly winds advected a cooler airmass into the
area yesterday. Northwesterly winds will diminish as a surface
ridge moves across the Central Plains. Cloud cover will also
diminish through the day and we should see some sunshine by the
afternoon.

As the surface ridge moves east into Iowa this afternoon, flow
will return to the southwest this evening. Strong warm air
advection from the southwest combined with clear skies Saturday
should lead to temperatures near or above 50f for much of the
area. Low level moisture and cloud cover will lead to about the
same temperatures on Sunday.

Monday through thursday:
on Monday, a low pressure system currently visible on water vapor
about 500 miles west of the West Coast is forecasted to impact the
area. A strong trough will bring an Arctic cold airmass into the
Midwest. The cold front could lead to some light snow in far
northeast Nebraska (wayne, Niobrara, Neligh, crofton) Monday
morning with totals less than an inch. Strong winds behind the
front could result in wind chills at or below 0f. It is likely
that the high temperatures Monday will occur at midnight. Cold air
advection will result in temperatures dropping throughout the day.
The high temperatures Tuesday will range from 30f in southwest
Nebraska down to 20f in northeastern Nebraska. Temperatures
should rebound after Tuesday as the trough that moves through the
area into the East Coast becomes less amplified. Outside of the
chance for snow early Monday morning, the forecast is looking
mostly dry.
