Area Forecast Discussion
National Weather Service North Platte NE
637 PM CDT Mon Jul 7 2025

.KEY MESSAGES...

- An Enhanced Risk (Level 3 of 5) for severe thunderstorms
  across all of western and north central Nebraska late this
  afternoon and evening. Winds gusts in excess of 75 mph, hail
  larger than 2 inches in diameter, heavy rainfall, and a few
  tornadoes are all possible.

- Additional thunderstorms are possible Wednesday and Thursday,
  with the potential for some to be strong to severe. A
  Marginal Risk (Level 1 of 5) for severe storms across all of
  western and north central Nebraska for Wednesday, with the
  equivalent of a Slight Risk (Level 2 of 5) across most of the
  region on Thursday.

- Temperatures warm up through mid week. A cold front tracking
  through the region brings temperatures back below normal late
  week into the early weekend.

.SYNOPSIS...
Issued at 334 PM CDT Mon Jul 7 2025

A low pressure system is observed over south central South Dakota,
with a warm front bisecting Nebraska. A cold front is observed
across northern Nebraska. This places most of western and north
central Nebraska firmly within a warm sector this afternoon, with
steady moisture advection out of the southeast. In fact, we are
already observing dewpoints in the mid 60s, pushing into the low 70s
across portions of the region. Clear skies throughout the morning
have allowed for sufficient daytime heating, and instability has
been building across the region. A 500 mb trough is positioned just
north of the Nebraska-South Dakota border, providing upper level
support and enhanced deep layer shear. In short, the environment is
primed for severe convection this afternoon and evening.

&&

.SHORT TERM /THROUGH TUESDAY NIGHT/...
Issued at 334 PM CDT Mon Jul 7 2025

The Enhanced Risk (Level 3 of 5) remains in place over portions of
southwest into north central Nebraska, with a SLight Risk (Level 2
of 5) covering the rest of the North Platte County Warning Area. As
of early this afternoon, we are already observing attempts at
convection along the frontal boundaries, and believe it is a matter
of hours before stronger cells develop. Forecast soundings continue
to indicate ample CAPE with hodographs pointing to strong shear
across the region. Tend to agree with convective modes suggested in
CAM guidance this morning, indicating a greater supercell threat
across north central Nebraska, with a more linear threat across
western Nebraska.

For the supercell threat across north central Nebraska, certainly
believe all severe hazards are in play. Sufficient deep layer shear
should allow for discrete convection, and CAPE profiles suggest the
potential for large hail to develop in the more intense updrafts. In
fact, these cells still show potential for hailstones up to 2 inches
in diameter or greater. As low level shear is enhanced along an
intensifying low level jet tonight, cannot rule out the potential
for tornadoes as well. These cells are expected to track southeast,
remaining in north central to central Nebraska. As for the more
linear threat out west, storms are expected to develop along the
cold front, and quickly undergo upscale growth into an MCS. The MCS
brings the greatest threat for severe wind gusts across the region,
with gusts potentially exceeding 75 mph. While there may be some
hail threat with the MCS, this should mostly be limited to hail up
to 1 inch in diameter. Given the expected low level shear vectors,
still think that there is a tornado threat along the line,
especially late afternoon and early evening. As the evening
progresses, believe the tornado threat begins to wane and the wind
threat increases.

Also worth mentioning, is that CAMs have been in pretty strong
agreement on these two sectors of storms eventually coming together
over central and north central Nebraska. With the slower moving
supercells followed by the line of storms, this could potentially
bring some very heavy rainfall into portions of central and north
central Nebraska. This may lead to some localized flooding,
particularly in low lying areas. Long story short, stay weather
aware this evening, as there could be a multitude of threats across
the region.

As for tomorrow, ridging begins to develop across North Dakota,
helping to usher in a dry forecast. There is a slight chance for
some showers and thunderstorms across the northern Sandhills Tuesday
evening , however, this remains less than a 20 percent chance. Highs
climb into the mid to upper 80s across the region, which is pretty
typical for this time of year. Lows drop into the 60s overnight,
with skies remaining mostly clear.

&&

.LONG TERM /WEDNESDAY THROUGH MONDAY/...
Issued at 334 PM CDT Mon Jul 7 2025

Upper level ridging continues Wednesday morning, with a ridge
breakdown starting in the afternoon and evening. A shortwave tracks
across the northern Plains, along with a surface system.
Temperatures get quite warm on Wednesday, with highs in the 90s and
dewpoints again into the 60s. This will begin to build instability
across the region, and may provide the fuel for a few strong
thunderstorms. Will be keeping an eye on forecast trends for
Wednesday, as the severe potential increases. In fact, we are in a
Day 3 Marginal Risk (Level 1 of 5) across all of western and north
central Nebraska. At this time, the exact threats are still
uncertain, though hail and winds seem to be more likely.

For Thursday, an upper level trough tracks across Montana, bringing
a cold front across the region Thursday evening. Again, we see warm
temperatures and high dewpoints throughout the day, building
instability across the region. With the better forcing along the
cold front, there is a better chance for severe weather Thursday
afternoon and evening. the Storm Prediction Center has expanded
their 15% outlook, which is the equivalent of a Slight Risk, across
more of the region Thursday afternoon and evening. Again, will be
worth keeping an eye on forecast trends to solidify exact threats,
location, and timing.

After the cold front passes through the region, we get some cooler
temperatures across the region Friday and Saturday, with highs in
the low to mid 80s. With the upper level pattern remaining on the
active side, cannot completely rule out some additional rainfall to
kick off the weekend. As the jet stream lifts north again, the
pattern favors a return to warmer temperatures Sunday into Monday.

.AVIATION /00Z TAFS THROUGH 00Z WEDNESDAY/...
Issued at 635 PM CDT Mon Jul 7 2025

There will be a threat for thunderstorms in the vicinity of the
KLBF terminal from 01z to 05z this evening. Storms may be
capable of producing wind gusts to 45 KTS along with 3 miles of
visibility with moderate to possibly heavy rain. Skies will
then gradually clear out overnight with a few to scattered
clouds ranging from 20000 to 25000 FT AGL Tuesday morning into
Tuesday afternoon. At the KVTN terminal, expect scattered to
broken clouds around 20000 FT AGL into Tuesday morning. Skies
will then clear thereafter. There is a small threat for
thunderstorms through 02z this evening and will handle this with
a vcts and a tempo group.
