.SHORT TERM /THROUGH WEDNESDAY NIGHT/...
Issued at 336 PM CDT Mon Jun 15 2026

Red Flag Warning is on track across the Panhandle and western
Sandhills through early this evening. Gusty west to northwest winds
will continue late this afternoon then quickly decrease early this
evening.

Surface high pressure will slider southward overnight and be
centered across central Nebraska by Tuesday morning. With the dry
air and light winds, another cool night can be expected with lows in
the upper 40s and lower 50s.

Surface low pressure deepens across western SD during the day
Tuesday ahead of a strong shortwave diving southeastward toward the
Northern Plains. The surface low will deepen as it moves eastward
across SD overnight, and a 989mb center should be located across
eastern SD by sunrise Wednesday morning. Only meager moisture return
is expected Tuesday night ahead of the low, and little in the way of
any precipitation is expected with the deeper moisture and
instability remaining to our south. A strong Pacific cold front will
move from west to east across the area late Tuesday night into
Wednesday as the surface low shifts to the east. Deep boundary layer
mixing behind the front will promote stronger winds aloft mixing to
the surface through the day Wednesday. Area sounding profiles
support northwest wind gusts 40-45 mph through the day. Humidity
will be low, and fire weather headlines will likely be needed. See
the fire weather section below for further details.

.LONG TERM /THURSDAY THROUGH MONDAY/...
Issued at 336 PM CDT Mon Jun 15 2026

Surface high pressure settles into the area Thursday with winds
decreasing and cooler temperatures, with highs in the mid 70s to
lower 80s A long wave trough moves onto the west coast and into
the Intermountain west by Saturday morning. Return southerly
flow will develop Friday as surface low pressure deepens across
northeast CO. Higher theta-e air will begin to move northward
Friday night, with surface dew points rising into the 60s
Saturday. As the low pressure deepens through the day Saturday,
low-level flow will back to the southeast across southwest
Nebraska. High instability and adequate shear will provide the
potential for severe storms with any late afternoon development.
Supercells would likely be the mode early on, transitioning to
possible MCS development during the evening as a strong
southerly low-level jet continues to advect moisture northward
into the area.

.AVIATION /18Z TAFS THROUGH 18Z TUESDAY/...
Issued at 1229 PM CDT Mon Jun 15 2026

VFR conditions are expected to prevail over the next 24 hours.
Breezy winds will develop over the next few hours and persist
through the evening, with northwest to westerly winds of 10 to 15
knots and gusts up to 30 knots across the area. Winds will gradually
diminish this evening into the overnight hours, with west to
northwest winds around 5 knots expected by late tonight. Some broken
mid to upper level cloud cover will move across the area this
afternoon and evening into the overnight period.

.FIRE WEATHER...
Issued at 336 PM CDT Mon Jun 15 2026

Critical to near-critical conditions are expected each day through
Wednesday for much of western and central Nebraska.

Monday afternoon/evening...later today, a frontal boundary will
settle south out of South Dakota and lead to a wind shift to
northwesterly and then northerly. Speeds should briefly increase in
the wake of this frontal boundary. Arrival ranges from 5pm MDT in
the north to closer to 9pm MDT in the south. Gusts may climb to
around 25-30 mph for an hour or so before subsiding to less than 15
mph for much of the overnight. As winds lighten, they should again
become more variable with a slight persistence of westerly
direction. Humidity recovery will be poor overnight, particularly
across the southern Panhandle into southwest Nebraska, where values
may struggle to reach 60 percent.

Tuesday...near-critical to critical conditions are again likely for
the western Sandhills and eastern Panhandle. Westerly winds will
strengthen again beneath enhanced mid-level northwesterly flow.
Approaching thermal ridge from the west will bolster temperatures
off the surface and support very warm afternoon highs. Early morning
cloud cover should decrease in coverage slightly during the
afternoon but skies should remain partly cloudy in the afternoon.
With gusty west winds, mixing heights should push to around 10-12kft
AGL. Beneath a belt of stronger flow at h7 (~5-7kft AGL),
unidirectional low level flow will support afternoon gusts reaching
25 to 30 mph. Forecast highs will be warmer than Monday with values
in the middle 80s to near 90F for areas west of Highway 83. These
are approximately 5-10F above normal for middle June. Incoming air
originating from the higher terrain will support critical humidity
levels in Zone 204 with values in the 15-20% range for western zones
206, 208, and 210. Have maintained a Fire Weather Watch for Zone 204
given active Red Flag Warnings for Monday with likely need to update
later on. Will need to consider an extension to include the
overnight hours given especially poor humidity recovery of 40-55%
west of Highway 83 (55-70% east). Winds overnight will also back to
the south as a moderate low-level jet forms. Winds just off the
surface should increase to around 35-45 knots. This will keep winds
gusty overnight and play a large role in the poor humidity recovery.

Wednesday...critical fire weather conditions appear likely for much
of central and western Nebraska, largely driven by anticipated
magnitude of wind gusts. An approaching mid-level disturbance
will cross South Dakota and drag a cool front south into western
Nebraska. Recent trends have been to speed up the arrival of
this feature and as a result, daytime high temperatures have
fallen. That said, an influx of dry air beneath strong flow
aloft will support ample mixing allowing humidity to fall into
the 15-25% range. As flow off the surface continues to
strengthen, the deep mixing will tap into the belt of h7 flow of
40+ knots. As a result, wind gusts should climb to 40 to 45 mph
with the strongest north of the Platte River system. Daytime
highs will range from upper 70s in the north to lower 90s in the
far south. This is in an airmass characterized by dew points
falling into the 30s. Though humidity may be more marginal, the
expected magnitude of gusts drives the concern for the fire
conditions. Local partners have suggested that fuels continue to
green up but could still carry in the right conditions,
particularly stronger wind days. Should the current forecast
remain on track, headlines will be necessary to cover this
threat. Wind gusts should peak in the late morning/early
afternoon and only gradually subside into the evening. This may
prolong concerns well into the evening hours with potential for
humidity recovery to be hampered.
