237 PM CDT Mon Apr 28 2025

.KEY MESSAGES...

- A Slight Risk (Level 2 of 5) for severe thunderstorms across
portions of north central Nebraska this afternoon and evening. The
primary severe weather concerns will be large hail, with a
secondary threat for damaging wind gusts.

- Another appreciable chance for showers and thunderstorms Wednesday
afternoon and evening. Severe potential appears low at this time.

- Temperatures gradually warm from near seasonal to above seasonal
late this week into the weekend.

.SHORT TERM /THROUGH TUESDAY NIGHT/...
Issued at 236 PM CDT Mon Apr 28 2025

A secondary cold front will continue to drop south across the region
this afternoon and evening, bringing the potential for showers and
thunderstorms across western and north central Nebraska. Better
moisture remains available north of Highway 2, with afternoon
dewpoints in the 40s to low 50s. South of Highway 2, dewpoints
remain much lower, in the low 30s. Cumulus development, including
some showers and thunderstorms are already underway across portions
of western Nebraska and is expected to continue and intensify ahead
of the cold front. CAPE values are much more substantial across
eastern Nebraska, ahead of the primary cold front. However, there is
a suggestion of CAPE values in excess of 1,000 J/kg pooling over
portions of north central Nebraska, mainly along the Highway 183 and
Highway 281 corridors. The HRRR remains quite consistent today,
suggesting initial cell development supportive of supercells across
this portion of north central Nebraska. GIven the suggested higher
cloud base with these cells, and suggested inverted V patterns in
the lowest 2 km, believe the main severe threat will be large hail,
with a secondary threat of damaging wind gusts. This is further
backed by the SPC Slight Risk (Level 2 of 5) across portions of
north central Nebraska this afternoon. Have trended PoPs up in the
short term across north central Nebraska through this evening. As
the cold front pushes through, expect a quick end to precipitation
this evening as storms track further east.

Tonight, though showers and thunderstorms track out of the region,
the skies remain fairly cloudy. With the front pushing through, went
ahead and lowered lows tonight by a few degrees, as inherited
temperatures were sitting on the higher end of guidance. Skies begin
to clear out around sunrise, giving way to a mostly pleasant
Tuesday. Highs climb into the mid 60s, with no precipitation
expected. Winds may become slightly breezy behind the front,
however, should remain mostly under 20 mph through the afternoon
across the region. Skies remain partly cloudy overnight, with lows
into Wednesday morning dropping into the upper 30s.

&&

.LONG TERM /WEDNESDAY THROUGH SUNDAY/...
Issued at 236 PM CDT Mon Apr 28 2025

As an upper level trough pushes through the region on Wednesday,
another surface level disturbance is expected to track through the
region, bringing another chance of showers and thunderstorms
Wednesday afternoon and evening. Will need to monitor the potential
for a strong system across the southern Plains, which may limit some
of our moisture advection into the region. Afternoon CAPE looks to
be fairly low across the region on Wednesday, generally under 1,00
J/kg. Upper level winds also appear to be fairly weak, limiting
shear potential for more organized convection. Will be monitoring
short term forecast trends in case conditions change, but as of now,
not expecting storms on Wednesday to reach severe criteria.

As the trough exits the region, an upper level ridge tracks over the
region for a bit. An upper level low begins to develop across the
Desert Southwest, however, there is a bit of uncertainty in timing
for when this ejects over the Southern Plains.  For now, slight
chances of precipitation are in the forecast for this weekend,
mainly due to the uncertainty in the track of the upper level low.
There is some agreement in cluster analysis placing the low over the
southern Plains on Monday, potentially bringing our next chances for
rain. However, with this pattern developing, expecting that
temperatures remain near seasonal to slightly above seasonal mid to
late week, becoming above average by the weekend. For reference, our
average highs in North Platte are in the mid to high 60s for early
May. The current forecast calls for temperatures late week in the
upper 60s to lower 70s. By the weekend, we could see temperatures in
the upper 70s, with some suggestion of lower 80s. However, a lot will
depend on how the upper level pattern develops over the next few
days.

.AVIATION /18Z TAFS THROUGH 18Z TUESDAY/...
Issued at 1245 PM CDT Mon Apr 28 2025

Main aviation concern in the immediate short-term the threat for
convection to impact both terminals followed by expansive low-
stratus tonight introducing MVFR and possibly IFR conditions.

This afternoon, watching scattered cumulus develop across much
of the Sandhills ahead of increasing rain and thunderstorms
further northwest. Expect this activity to be the immediate
concern, particularly for VTN, where low-end VFR conditions are
likely and eventual thunderstorm activity will likely encroach
on the terminal by late afternoon. For now, held off on direct
impacts until closer to 28/23z (6pm CDT) with increasingly
degraded flight conditions through the evening behind a
progressive cool front. For LBF, believe potential thunderstorm
impacts could be greater though coverage will likely remain
scattered. Because of this, elected to cover with a tempo group
for now and will monitor trends/obs later to amend as necessary.

Behind the front, low stratus will be expansive across the area
and have maintained inherited MVFR conditions to both terminals
for much of the evening and overnight hours. Can't rule out
brief periods of IFR and potentially LIFR conditions but
confidence in including this into prevailing categories is too
low at this time. Expect conditions to slowly improve through
daybreak on Tuesday for all area terminals.
