SHORT TERM /THROUGH MONDAY NIGHT/

Issued at 320 PM CDT Sun Jun 7 2026

A low pressure system tracks across the northern Plains, bringing a greater severe risk north of the area. On the southern end of the larger system, a surface trough will track across the Panhandle this afternoon and evening, which will provide a source of lift for potential showers and thunderstorms. With the ongoing surface heating, still expecting around 1,500-2,000 J/kg of surface based CAPE across northwest Nebraska. However, deep layer shear remains relatively meager, generally on the order of around 25 knots, which may limit potential for more organized convection. Forecast soundings across the northwest suggest steep lapse rates, though, and fairly strong low level mixing. All of this points to a fairly marginal severe weather set up late this afternoon and evening, conditional on whether storms can form and remain somewhat isolated. A Marginal Risk (Level 1 of 5) for severe thunderstorms remains in effect for northwest Nebraska, with the main threats being large hail and severe wind gusts. With the expected low level mixing, believe strong thunderstorm wind gusts will be the main threat, but cannot rule out the potential for some isolated large hail should a stronger storm develop in the environment. Throughout the rest of the night, the surface trough may initiate some weaker showers and thunderstorms which are expected to track across the Sandhills. The severe risk remains low with any storms after midnight, with storms overnight mostly bringing rainfall across portions of the region.

With the larger system tracking across North Dakota, expecting the cold front associated with the system to track across the region on Monday, eventually stalling across the Sandhills. The cold front will be the catalyst for a greater severe weather threat Monday afternoon and evening across the region. Dewpoints are expected to climb into the upper 50s to lower 60s across eastern portions of the region, and potentially west into the Sandhills. Still a little uncertainty remains in how far west these higher dewpoints track, which will have impact on the exact scope of severe weather threats. Even with some uncertainty in dewpoints, SPC has issued a Slight Risk (Level 2 of 5) across portions of western and southwest Nebraska, with the rest of the region in a Marginal Risk for severe thunderstorms. However, stronger instability is still expected to develop across the region, especially across southwest Nebraska. In addition to the stronger instability, deep layer shear is expected to be on the order of around 50 knots. In this environment, supercell development will be possible along the frontal boundary, posing a risk for large hail and severe wind gusts. In addition to this, a tornado or two cannot be ruled out, especially across far southwest Nebraska in vicinity of the front. As the evening evolves, storms are expected to grow upscale into a more linear system, continuing the risk for severe wind gusts. These storms will also pose a risk for heavy rain, with CAM guidance suggesting amounts above an inch under more intense convection.

LONG TERM /TUESDAY THROUGH SUNDAY/

Issued at 320 PM CDT Sun Jun 7 2026

Tuesday, hot temperatures are expected across the region. Anomalous 850 mb temperatures build across the region, and a dry line tracks across the Sandhills. With the warm temperatures aloft and relatively low humidity across the region, expecting highs to push into the 90s across the region, with potential for some areas to reach the lower 100s. Latest probabilistic guidance suggests highs in the 90s are a near lock across the region, with a 70 percent chance of highs exceeding 95 degrees. There is still a suggestion of highs breaking 100, especially along and south of the Interstate 80 corridor, where there is a 40 percent chance of highs breaking 100.

With the highs pushing well above average on Tuesday and the dry line tracking east, very low humidity builds across western Nebraska. Across the eastern Panhandle into the western Sandhills, relative humidity values are expected to reach into the 10 to 20 percent range. Conditions will also be breezy on Tuesday, with sustained southwest winds around 20 to 30 mph and gusts up to 45 mph. With the combination of hot temperatures, very low humidity, and gusty winds, near critical to critical fire weather conditions are expected across western Nebraska, and as such, a Fire Weather Watch has been issued for Tuesday afternoon and evening. Adding some concern, thunderstorms may develop along a cold front and track across the northern Panhandle Tuesday evening. Given the dry environment, little precipitation is currently expected, which may introduce a risk for gusty erratic winds and lightning. Additionally, with the dry line in play and frontal passage, expecting very poor humidity recovery overnight, with humidity recovering around 40 to 50 percent. At this time, wind gusts are expected to end by late evening, which may limit overnight concerns. However, will continue to monitor this set up, as potential for fire weather appears quite high Tuesday afternoon into the evening.

Guidance continues coming into consensus for Wednesday, indicating cooler highs across most of the region, especially across the northwest. Highs are currently expected to range from the 80s to low 90s. Latest probabilistic guidance suggests around a 50 percent chance of highs breaking 90 on Wednesday, especially along and south of the Interstate 80 corridor and across portions of central and north central Nebraska. However, even with the cooler highs, very dry air remains across most of the region, and very windy conditions are expected to persist. Most of the area is expected to see afternoon humidity values less than 20 percent, with western Nebraska, southwest Nebraska, and the Sandhills in the 10 to 15 percent range. Strong westerly winds are expected, with sustained winds of 20 to 30 mph, and gusts in excess of 45 mph. The continued low humidity and gusty winds may lead to additional near critical to critical fire weather concerns across the region. Will continue to keep an eye on the forecast trends, as there is some question on how far the cold front pushes east, which may determine the extent of the impact.

Late week, temperatures are expected to return to the 80s across the region, remaining slightly warmer than seasonal average. For reference, our highs for mid June are typically around the lower 80s. Currently, conditions are expected to remain mostly dry and breezy, so could see continuing fire weather concerns late week. Though there is a slight chance of showers building in by the weekend, confidence remains on the lower side, given some uncertainty in the upper level pattern.

AVIATION /18Z TAFS THROUGH 18Z MONDAY/

Issued at 1227 PM CDT Sun Jun 7 2026

VFR conditions are expected to prevail today and tonight across western and north central Nebraska. Gusty southerly to southeasterly winds are expected to last through the afternoon, with strongest gusts across northern and western portions of the region. Winds are expected to remain gusty across western Nebraska into north central Nebraska overnight, though gusts are expected to diminish across southwest Nebraska overnight. Showers and thunderstorms are expected to develop across western Nebraska this evening, tracking to the east. While thunderstorm activity is expected to wind down before reaching KVTN, a few showers and thunderstorms may track across the Sandhills into the KLBF terminal. Confidence for thunderstorms is still on the lower side, so have left this PROB30 for now.

FIRE WEATHER

Issued at 320 PM CDT Sun Jun 7 2026

Near critical fire weather conditions are expected to continue across western Nebraska through the evening, largely driven by strong gusty winds and above average temperatures. A brief break is expected on Monday, as conditions become less breezy, and humidity remains above 30 percent.

Near critical to critical fire weather conditions return on Tuesday, especially across western Nebraska into the western Sandhills. As a dry line tracks across the region, very dry air will accompany well above average temperatures. Winds are expected to remain gusty on Tuesday, as well. With this combination, have opted to issue a Fire Weather Watch Tuesday afternoon into the evening. Humidity recovery remains poor overnight, though winds may become less gusty. Conditions appear favorable to continued fire weather concerns Wednesday afternoon as humidity remains poor, with gusty winds.
