KEY MESSAGES

- Moderate confidence in below freezing temperatures tonight which will result in widespread freeze conditions.

- High confidence in a return to critical fire conditions on Saturday as dry and breezy conditions return.

- Elevated to potentially critical fire weather conditions possible Monday through Wednesday, along with highs in the low to mid 80s.

- Increasing confidence that higher humidity late Wednesday into Thursday ahead of an approaching storm system will bring an increased chance for showers and thunderstorms.

SHORT TERM /THROUGH SUNDAY/

Issued at 310 PM CDT Fri Apr 17 2026

Some light precipitation is showing up on radar across northwest Nebraska this afternoon. Looking at the latest observations, little to no precipitation is actually making it to surface and the snow that does isn't causing too many impacts at this time. The biggest impact will be some reduced visibility due to the falling snow. Precipitation is expected to continue shifting to the southeast throughout the afternoon, but will slowly begin to dissipate as it approaches the US-83 corridor. Therefore, any accumulations or impacts will be mainly confined to the northwest/Pine Ridge region.

As the snow diminishes by late afternoon, clouds will also begin to scatter out, becoming mostly clear by late evening. This clearing will help to promote some abnormally cold temperatures tonight, at least abnormal from what we've been seeing the last few weeks. Clear skies, light winds, and cold air advection pushing into the region will all combine to create a favorable environment for temperatures to drop well into the low to mid 20s across the entire region tonight. With confidence remaining high in these chilly temperatures overnight, have gone ahead and upgraded the freeze watch to a freeze warning. Along with the chilly temperatures, widespread frost is expected across areas primarily south of Highway 2 and in the freeze warning area which could impact early season crop growth/plants, damage to outside plumbing and irrigation, and create a dangerous environment for livestock. Those with any of the previous concerns should take precautions to protect pipes, outdoor animals, and plants.

Heading into the weekend, a dry forecast is expected across all of Nebraska as upper level ridging builds in across the western US and surface high pressure starts to build into the Plains. Temperatures will remain below normals on Saturday with highs only rising into the 50s, maybe hitting 60 degrees across extreme southwest Nebraska. Low temperatures on Saturday night will be chilly once again, but a few degrees warmer than Friday night. At this time, no freeze headlines are in effect, but they may be necessary as overnight lows still drop into the mid 20s across the forecast area. High temperatures will continue on a warming trend into Sunday, returning back above normal (low 60s) for most locations. Highs will range from the low 60s in the O'Neill area up to the mid 70s in southwest Nebraska.

LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/

Issued at 310 PM CDT Fri Apr 17 2026

Upper level ridging will build across the region Sunday night. By Monday, the ridge will begin to break down as a shortwave moves north of the region. Ridge breakdowns across the area often correlate with increased fire weather conditions, which appears to be the case Monday. 850mb temperatures are expected to reach 15 to 20 C by Monday afternoon, supporting highs into the 80s across most of the area. Gusty southwesterly winds behind the dryline, combined with relative humidity values in the 10 to 15 percent range, will promote elevated to potentially critical fire weather conditions by Monday afternoon. This will continue to be monitored in future forecast updates.

On Tuesday, the ridge will expand and shift poleward, with the core of the upper level ridge remaining just west of the area. This will again support highs in the low to mid 80s Tuesday afternoon. Relative humidity values may fall as low as 10 to 20 percent, but with winds generally remaining around 10 to 15 mph, the fire weather threat should remain lower compared to Monday. However, with continued dry conditions in place, any increase in wind speeds stronger than currently forecast, would lead to greater fire weather concerns.

Heading into Wednesday, the ridge axis will begin shifting east as a southern stream trough moves into the western United States. This trough will promote lee cyclogenesis east of the Rockies, leading to increasing southerly flow across the Central Plains. Winds will be stronger on Wednesday, but dewpoints rising into the upper 40s to low 50s could help limit fire weather concerns.

From Wednesday night into Friday, this upper level disturbance is forecast to eject into the region. With improving moisture return and greater large-scale ascent ahead of the system, there is an increasing chance for showers and thunderstorms Thursday afternoon into the Thursday night. Current guidance suggests the main system moves into the region sometime between Thursday into Friday, with a fairly significant associated surface low. The timing, track, and intensity of this system will be important in determining the potential for better precipitation chances across the area. With this system being about a week out, uncertainty remains regarding thunderstorm and precipitation chances. At this time, the GEFS is somewhat more favorable for precipitation across the area, while the EPS model guidance keeps better precipitation chances farther east. Given recent trends this winter into this spring, with the heavier precipitation often ending up east of the area, confidence in widespread precipitation remains limited. Stay tuned for future forecast updates as model guidance continues to resolve the uncertainties with this system over the next several days.

AVIATION /00Z TAFS THROUGH 00Z SUNDAY/

Issued at 625 PM CDT Fri Apr 17 2026

Light rain and snow continue to move east-southeast and should weaken over the next couple of hours. Gusty northwest winds will continue but should weaken through the evening. Low ceilings associated with the precipitation will improve, with VFR conditions returning by late evening and continuing through the remainder of the period. Winds will increase once again Saturday morning into the afternoon, with northwest winds of 15 to 25 kts and gusts up to 35 kts.

FIRE WEATHER

Issued at 310 PM CDT Fri Apr 17 2026

Critical fire weather concerns are expected to return on Saturday as RH values drop and winds increase. Humidity will drop to below 15 percent for much of the region with some locations across south central Nebraska dropping to near 12 percent. Northwesterly wind gusts up to 35 mph are anticipated across the region. A Red Flag Warning is now in effect from late Saturday morning through early evening due to these strong winds, lower RH values, and cured fuels ready to burn. Overnight RH values will only recover to 45 to 55 percent south of I-80 and only into the 55 to 65 percent elsewhere. Humidity values drop back into the 10 to 15 percent range, with some locations dropping below 10 percent on Sunday. Despite winds being lighter on Sunday, some near-critical to critical fire conditions are still expected as temperatures start to warm and afternoon RH drops. Conditions are not expected to improve through next week as warm and dry weather persists and precipitation remains minimal. Expect continued near-critical to critical conditions through at least the middle of next week.
