.SHORT TERM /THROUGH WEDNESDAY NIGHT/...
Issued at 304 PM CDT Tue Jun 24 2025

Thunderstorm chances tonight and severe potential is the main
forecast challenge over the next 12 to 18 hours. There are two
areas of concern for thunderstorm development late this
afternoon into the evening hours. The first area is over the
higher terrain of northeastern Colorado and far southeastern
Wyoming. The second area of concern is over far southwestern
Nebraska in the vicinity of a northward advancing warm front.
The thunderstorm and severe threat with the latter area will be
highly conditional. If development can be realized, believe
there will be a decent threat for thunderstorms, some severe
with damaging winds, large hail and a tornado or two. With
steering winds being from the south-southwest and the warm front
being oriented from east to west, storms which migrate north of
the boundary, have a decent potential to produce large hail.
This activity, if it materializes, will eventually get absorbed
by storms which have initiated over the front ranges of Colorado
and southeastern Wyoming. With the first area of convective
development (northeastern Colorado and Wyoming), large hail will
be the initial threat, mainly west of the forecast area. As
this activity tracks east and merges with the possible storms
over southwestern Nebraska, the severe threat will be more of a
strong straight line wind issue. After the merger, convection
will track to the northeast, traversing the forecast area into
the early overnight hours. On Wednesday, a quasi-stationary
frontal boundary will remain anchored across the central
Sandhills. With afternoon heating and little to no cap noted,
showers and thunderstorms should develop quickly during peak
heating. Convection and storm mode on Wednesday appears "messy"
per the latest CAM solns from this morning. Deep layer shear is
on the order of 25 to 30 KTS Wednesday afternoon, so if any lone
storms can develop, we could see a strong storm or two.
However, at this time, the severe threat appears fairly marginal
ATTM. As for highs on Wednesday, with the warm front being
anchored over the central and northern Sandhills, highs will
range from the upper 70s in the northwest to middle 80s in the
southeast.

.LONG TERM /THURSDAY THROUGH TUESDAY/...
Issued at 304 PM CDT Tue Jun 24 2025

Precipitation will lift east of the area Thursday morning. A
more zonal pattern will set up across the central and northern
CONUS Thursday into Thursday night leading to dry conditions
across the area. A northern stream disturbance will force a
frontal boundary into the Dakotas Friday night. Though the main
threat for storms appears north of the area, couldn't rule out a
stray storm over northern Nebraska Friday night. Also, the
latest severe weather outlook for day 4 has a 15 percent severe
risk over north central Nebraska. Better chances for more
widespread thunderstorms appears on Saturday as the northern
stream trough forces a frontal boundary through the forecast
area. After Saturday, low amplitude westerly or west-
northwesterly flow will continue into early next week. This will
lead to a continued threat for isolated to scattered showers
and thunderstorms each day. Temperatures will be seasonal with
highs generally in the middle 80s.

.AVIATION /00Z TAFS THROUGH 00Z THURSDAY/...
Issued at 631 PM CDT Tue Jun 24 2025

Areas of MVFR and IFR will continue through at least Wednesday
morning across portions of northern Nebraska. In addition an
area of showers and thunderstorms will move across the area this
evening into the overnight hours. Variable and gusty winds can
be expected in and near any thunderstorm activity.
