.KEY MESSAGES...

- A line of strong to severe storms is on track to cross from
  northwest to southeast across the full area between mainly 7PM

- The strongest storms will be capable of producing damaging
  wind gusts up to 60-70MPH. Though not the main concern, hail
  up to the size of quarters may also be possible.

- The next chance of precipitation (20-50%) does not come until
  Tuesday night for central Nebraska.

- Highs will range the 80s on Friday and Saturday, with a mini
  warm up heading into the start of the new week (upper 80s and
  90s).

.DISCUSSION...

Tonight...

Steady southerly winds gusting as high as 20MPH early this afternoon
have helped advect in a warmer and more humid airmass today (70s to
low 80s dewpoints). Despite the excessive cloud coverage for most of
the day so far, temperatures still look to remain mostly on track to
reach the mid 80s to low 90s for much of central Nebraska.
Temperatures across some north central Kansas locations and far
southwest Nebraska areas may peak as high as the mid to upper 90s
today. The main story, however, will be of the potential for severe
weather this evening.

An upper-level shortwave trough ejecting out from eastern
Colorado/Wyoming this afternoon has lead to some mid-level pressure
falls as well as some vorticity and cold air advection across the
region. The warming temperatures at the surface paired with cooling
aloft has helped increase instability/buoyancy (up to 2,000-
3,500J/kg of MUCAPE). A 1004mb surface low deepening across central
Nebraska this evening will help steer frontogenesis across central
Nebraska and central Kansas. A cold front emerging from this process
will in turn help develop a cluster of storms. Storms organizing
into a line this afternoon, will be expected to drive southeast
through much of the area between mainly 7PM and 1AM tonight. As of
2PM today, this line of storms looks to be already taking shape in
cherry county in Nebraska based on the latest radar reflectivity
returns and the agitated cumulus observed on satellite.

A few of these storms will have the potential to become strong to
severe with damaging winds being the primary concern. Given the
presence of modest deep layer shear (25-40MPH) with sufficient
instability and moisture, the base ingredients will be met for
severe storm characteristics. Though hail up to the size of quarters may
still be possible within a few of the stronger/taller storms, the
high freezing levels with more unfavorable mid-level lapse rates (5-
6C/km), should generally keep the hail threat more limited tonight.
In addition, though heavy downpours will be expected within several
of these storms (1.5-2" PWATS), given their fairly progressive
nature, the overall flooding threat should remain limited. The Storm
Prediction Center now includes the full area in a slight risk (level
2 of 5) for severe weather.


Friday through Wednesday...

Following the exit of the storms tonight, the forecast remains dry
until Tuesday night (20-50% chances for central Nebraska). This
drier pattern will come as southwest U.S. ridging expands northeast
into the Central Plains over the weekend. The surface low pulling
east and away on Friday will leave behind gusty northerly winds that
may peak as high as 30-45MPH during the afternoon. Meanwhile, drier
and relatively "cooler" temperatures with keep highs peaking in the
80s for both Friday and Saturday. Higher pressure eventually
settling back in over the weekend will lighten winds with
directions becoming southerly again by Sunday. The start of the new
week will bring warming temperatures once more with highs returning
back to the mid 80s and 90s.

Issued at 621 PM CDT Thu Jul 30 2026

For KGRI/KEAR Airports:

A line of strong to severe storms will impact both terminals
during the mid-evening hours...gradually tapering off around
31/05-31-07Z. Winds will then increase out of the north behind
the associated cold front after daybreak Friday, with gusts
30KTS+ possible aft 31/15Z. Expect temporary MVFR CIGS with
TSRAs to start this evening, with solid MVFR CIGS filling in
behind the storms overnight along with the possibility for some
MVFR VSBYS and light BR as well towards daybreak. CIGS should
clear during the mid to late afternoon hours with VFR conditions
returning to both terminals on or before 31/23Z.
