KEY MESSAGES

- Fire weather concerns continue through Wednesday.

- Cooler weather again Thursday behind a strong cold front.

- Potential for strong to perhaps severe thunderstorms returns to the area Saturday afternoon into Saturday night.

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 /00Z TAFS THROUGH 00Z WEDNESDAY/

Issued at 631 PM CDT Mon Jun 15 2026

VFR conditions will persist through the TAF period as upper level ridging remains in place. Some stronger winds early this evening will diminish after sunset giving way to winds under 10 knots through mid Tuesday morning. Southeast winds will gradually increase by late morning and through the afternoon with gusts up to 20 knots.

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.
