KEY MESSAGES

- Critical fire weather conditions are expected Monday for the Panhandle into far western Sandhills where Red Flag Warnings are in effect.

- Warm and dry conditions are likely for most locations much of the upcoming week, prolonging fire weather concerns.

- More unsettled weather arrives by late week with increasing precipitation potential across the region.

SHORT TERM /THROUGH MONDAY NIGHT/

Issued at 303 PM CDT Sun Jun 14 2026

This afternoon, steady low stratus hung on across the Panhandle into southwest Nebraska. Temperatures have been held in check as a result with low to middle 60s. Further east, increasing breaks and eventually clear skies has allowed for temperatures to climb. Early afternoon readings range from upper 60s to lower 70s across the area. Even in the warmer areas, all values remain below normal for middle June though this cooldown will depart as quickly as it came.

For tonight...believe tonight will prove to be fairly cool across much of local area. Surface high pressure extending southeast along the lee of the northern Rockies will drift off the higher terrain and through western Nebraska during the overnight. Winds will lighten and become mostly variable as a result. Low-level moisture should be shunted south as a result with decreasing dew point values through the evening. Skies will gradually clear, with a window from after midnight to just prior to dawn Monday for optimal radiational cooling. Statistical guidance continues to hone in on middle to upper 30s for the west central Sandhills into the eastern Panhandle. This appears plausible given the overall setup and could occur prior to approaching high level clouds around sunrise Monday. Recent HRRR guidance supports the notion while painting values as low as 36-37F between Alliance and Hyannis while the NAM Nest is further north towards the Pine Ridge. HREF probabilities show reasonable spread with 40% potential anywhere in Sheridan County but a more focused bullseye in rural areas north of Antioch. The current forecast calls for lows bottoming out around 38F in the mentioned areas. While no extensive climatological sites exist in the immediate area, a quick look at the history from the Alliance Airport shows values colder than 45F on 06/15 have only occurred 5 times since 1997. This is certainly atypical of middle June forecast lows. Further south, more extensive cloud cover and possibly some light precipitation chances should promote a sharp warming gradient just south of the Platte River with upper 40s to lower 50s appear probable.

Monday/Monday Night...critical fire weather conditions appear likely for our western zones, with details regarding this found below in the Fire Weather discussion. Modest high pressure will settle southeast with south to westerly flow becoming established across the area. Within the enhanced northwesterly flow, a disturbance will dive southeast out of the Northern Plains and cross the Dakotas. Main upper-level dynamics will largely remain north and east of the area but a trailing cool front will quickly settle out of western South Dakota. Afternoon highs got a subtle boost across the area given favorable downsloping flow winds nearing 25 to 35 mph beneath warm h85 temperatures and favorable compressional warming with the advancing front. Winds will flip in the evening with the arrival of the front but fropa should remain dry. This is largely due to precipitable water values of 0.60" or less, or roughly 50-75% of normal for the time of year. Winds behind the front are not expected to be overly significant with a brief continuation of 20-25 mph gusts out of the north but quickly subsiding thereafter. Low temperatures should not be as chilly with values ranging from upper 40s to middle 50s.

LONG TERM /TUESDAY THROUGH SUNDAY/

Issued at 303 PM CDT Sun Jun 14 2026

Amplified northwest flow will continue much of the upcoming week. This will support largely dry conditions and when factored with general downsloping flow, above normal temperatures. Upper ridge to the west will relax some as another Pacific Northwest trough departs southwest Canada. This feature will pass through the Central Plains around Wednesday with a trailing cool front expected to knock temperatures down from upper 80s/middle 90s on Wednesday to upper 70s/lower 80s for Thursday. Precipitation potential will be stymied by the lack of greater atmospheric moisture though Chance PoPs (up to 30%) continue for our far northeast zones. Ridging will begin to build east by late week with approaching ridge axis towards Friday/Saturday. Breakdown begins promptly with broad troughing across the western CONUS. This allows southwesterly flow to return which is more supportive of richer moisture quality and greater precipitation potential. By late Saturday/early Sunday, a more pronounced mid-level disturbance should cross the central Rockies and bring some greater rainfall potential to the area. PoPs from the model blend climb to around 40% Saturday afternoon but increase further towards 60% Saturday night into early Sunday. Precipitation potential should continue into the following week and this should support cooler temperatures again with a return to 70s and lower 80s forecast by Sunday.

AVIATION /18Z TAFS THROUGH 18Z MONDAY/

Issued at 1246 PM CDT Sun Jun 14 2026

VFR conditions are expected through the forecast period.

Mid-level cloud cover will be prevalent through the next 24 hours but should remain at or above 7kft AGL. Breezy northwest winds will subside this evening, becoming more variable, before resuming out of the west by late morning on Monday.

FIRE WEATHER

Issued at 303 PM CDT Sun Jun 14 2026

Critical fire weather conditions are likely on Monday for western Nebraska with a Red Flag Warning in effect for Zone 204.

Behind departing high pressure, westerly downsloping flow should develop across much of the area by late morning. A modest trough across the Northern Plains coupled with weak surface high pressure now to the south and east will lead to a compressed pressure gradient and strengthening winds through the day. Increasing influence from approaching thermal ridging coupled with the westerly flow will support a warm up across the area. Forecast highs range from upper 70s to lower 80s which are fairly seasonable values for mid June. Trajectories suggest minimal airmass change ahead of the approaching from later in the day which support dew points holding in the middle 30s without considering the introduction of descending dry mid-level air which is suggested by most NWP solutions. The lingering uncertainty is timing of arrival of this drier air with an immediately prior to fropa arrival being advertised by NAM12/RAP solutions. This may delay the lowest humidity levels to later in the day with a fairly progressive dry air plume limiting time a single location sees critical levels (15% or less). Winds appear to be fairly reasonable confidence with expansive 80%+ probabilities for exceeding 25 mph gusts west of Highway 83 which appear to favor mid to late afternoon as well. This aligns with an approaching h7 speed max as the h7 shortwave enters eastern South Dakota. HREF and NBM probabilities show good agreement in painting 50%+ joint probabilities of > 15 mph winds (sustained) and < 20% minimum humidities and with this in mind, did upgrade the inherited Fire Weather Watch to a Red Flag Warning. Though portions of Zone 204 have seen rainfall surpluses in the past week, the spotty coverage and recent updates that fuels remain receptive in drier areas supports the upgrade. Duration and magnitude of humidity drop further east casts doubt on reaching Red Flag Warning criteria thus no additional headlines were issued. Frontal passage appears to favor late afternoon through early evening north to south. The frontal boundary does not appear particularly sharp so a more gradual versus abrupt wind shift appears probable. And while some increased gusts area possible for a brief period behind the departing front, duration appears to be limited to an hour or two before winds again subside quickly. Poor humidity recovery is expected Monday night with values only reaching the 50-65% range heading into Tuesday.

Fire weather concerns continue near daily this upcoming week with a return to above normal temperatures and lack of greater moisture in place. Critical conditions appear possible again each day Tuesday and Wednesday as temperatures return to the upper 80s to lower 90s. How much overlap we see of critical humidity and strong gusts remains somewhat in question. This is especially true on Wednesday, which appears to be one of the warmer days of the week, as another frontal boundary will settle through the area and recent trends have sped this up to a mid-afternoon passage which will hinder humidity drop. Confidence in precise timing remains limited so stay tuned. Following a slightly cooler day on Thursday, warmer temperatures return for Friday before a more unsettled pattern arrives for the weekend which could lead to the return of greater precipitation potential across the region.
