.SHORT TERM /THROUGH SATURDAY/...
Issued at 350 AM CDT Thu May 9 2024

A weakening area of upper level low pressure is drifting southward
into Nebraska this morning. Cumulus clouds will rapidly form this
morning as the boundary layer warms beneath cold air aloft (-2C at
H7). Isolated to scattered showers will develop...and there is a
small amount of CAPE present by midday continuing through this
afternoon. Will continue the mention of isolated thunder this
afternoon. Flow aloft is quite weak so any storm will likely be
short lived. Otherwise a cool day is expected, especially across
western/northwest Nebraska where more cloud cover will limit highs
to the upper 50s.

The upper low essentially splits by Friday. Part of the energy
drifts southwest and becomes cutoff across the southwest U.S., with
the rest of the energy being absorbed into a fast southeastward
moving shortwave diving across the Great Lakes Region. The
shortwave across the Great Lakes will drive a weak Pacific cold
front southeast through the area. Actually, it won`t be colder
behind this front Friday as we will loose the cloud cover. Highs
should range from the mid 60s to lower 70s.

The southwest U.S. upper low begins to drift into Colorado Saturday.
Subtle upper level ridging develops across the southern into the
central plains ahead of this feature. Temperatures will warm to
above average as a result, with mid 70s common area wide.

.LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...
Issued at 350 AM CDT Thu May 9 2024

Upper level low pressure pushes through Colorado toward western
Kansas Sunday. Some moisture return occurs Saturday night into
Sunday with surface dew points rising into the lower 50s. Conditions
become somewhat unstable by Sunday afternoon and should see a few
scattered showers/thunderstorms develop across the area. The better
chances are across southern/southwest Nebraska in closer proximity
to the upper low. Flow aloft is weak and severe weather looks
unlikely with this system. The upper low tracks across Kansas Monday
with continued precipitation chances, especially across southern
portions of the area. Tuesday the upper low drifts east of the area
while a shortwave dives southeast across the northern plains. A cold
front associated with this could bring a round of convection to the
area Tuesday evening.

Above average temperatures are expected Sunday through Tuesday with
highs well into the 70s. Wednesday will cool back to near normal
behind the cold front with highs mid 60s to lower 70s.

.AVIATION /00Z TAFS THROUGH 00Z FRIDAY/...
Issued at 1145 PM CDT Wed May 8 2024

Mostly quiet aviation conditions are expected over the next day.
Stronger winds will develop during the afternoon on Thursday, but
should remain below 20 knots. Another round of light rain showers
are expected once again across northern Nebraska on Thursday
afternoon. Any impacts should be minimal and brief. Any isolated
showers across northern Nebraska will dissipate after sunset with
VFR conditions returning to the region.
