.SHORT TERM...(Today and tonight)
Issued at 330 AM CDT Sat Apr 20 2019

Surface high pressure is over the region early this morning with
clear skies and light winds. Temperatures are currently in the
upper 30s to the lower 40s with lows still expected to drop into
the middle 30s to around 40 degrees with some lower 30s possible
in a few localized areas. Areas of frost are still expected this
morning. Will continue the Frost Advisory as is through 8AM this

After a cool start to the day temperatures will rebound nicely
this afternoon as highs top out in the lower 70s under mostly
sunny skies and generally light southerly winds.

Mild conditions will occur tonight into Sunday morning as lows
drop into the upper 40s to the middle 50s.

.LONG TERM...(Sunday through Friday)
Issued at 330 AM CDT Sat Apr 20 2019

Surface low pressure will move into the Plains on Sunday with
southerly winds increasing. Gusts over 30 mph will be possible at
times on Sunday, especially across southeastern Kansas and
western Missouri. The gusty southerly winds will help usher an
even warmer air mass into the area on Sunday, as highs warm into
the lower to middle 80s, under partly cloudy skies as clouds
increase from west to east during the day.

An upper level trough will move onto the west coast today then
dig south into the southwestern U.S. by Monday as it closes into
an upper level low. The low will then slowly shift to the east
through much of the week. The area will be in southwest flow aloft
through the week and will keep mild conditions in place across the
region as highs warm into the 70s and lows cool into the 50s each

Several upper level disturbances will move through the area at
times from Sunday night through the week ahead of the approaching
upper level system. These disturbances will bring chances for
showers and storms to the area at times. Showers and storms will
be possible each day, but we are not expecting continuous rain
during the period. This pattern is not really a good setup for
widespread severe weather or flooding. The main risk will be
lightning with any storms.


.AVIATION...(For the 12Z TAFS through 12Z Sunday morning)
Issued at 522 AM CDT Sat Apr 20 2019

VFR conditions will occur across the area today and tonight as
surface high pressure moves across the region. Winds will be out
of the northwest early this morning and slowly swing to the west
this afternoon, then the southwest this evening and tonight.
