DISCUSSION

Issued at 201 PM CDT Mon Jun 15 2026

Today and Tomorrow:

Broad troughing over the eastern two-thirds of the CONUS is evident in afternoon water vapor imagery, with ridging continuing to hold over the Pacific Coast. A ridge of high surface pressure rules over our weather today, with westerly winds and dry weather making for a beautiful day to be outside. Highs will top out in the upper 70s to low 80s, with only a few gusts to 20-25 mph expected this afternoon, primarily across northeast Nebraska. A frontal system is inbound for the late evening/overnight hours, that will really struggle to amount to much more than a sprinkle or two across far northeast Nebraska and northwest Iowa thanks to measly instability and moisture as it passes.

Tomorrow will see temperatures increase, with southwesterly to westerly winds developing during the morning hours as a warm front takes shape to the west. Strong warm air advection and lift near the front itself will try to spur on some afternoon showers and a stray rumble of thunder, but chances for any meaningful, widespread rainfall remain low.

Wednesday and Beyond:

Wednesday continues to be of concern on a few fronts: the heat, storm chances, and potential fire danger across northeast Nebraska. Temperatures in the upper 80s to low 90s will be the peak of heat over the next 7 days, with the edge of it being taken off by the passage of a front that helps scour out moisture and increase winds locally. Those winds are expected to gust to 35-45 mph, with humidity values being low enough to drive very high to potentially extreme fire danger across northeast Nebraska during the afternoon hours. That passing front will also help drive shower/storm chances to the northeast, and later in the afternoon to the southeast. The timing of the front will make it difficult for any severe threat to linger very long during the afternoon hours before it slips to the southeast of the area. It appears that the storms that do from will quickly grow upscale, muting the upwards potential for hazards while still keeping everything on the board before they move out.

Winds will take a bit to calm down but once they do, a beautiful day in the upper 70s to just over 80 degrees will carry us into the end of the week. Highs do trend upwards Friday/Saturday, with a more summer-like feel to the day-to-day forecast -- including increasing potential for late evening/overnight storms plowing eastward from the High Plains.

AVIATION /18Z TAFS THROUGH 18Z TUESDAY/

Issued at 1158 AM CDT Mon Jun 15 2026

VFR conditions are forecast through the next 24 hours, with westerly winds starting to gusts to 20 kts near KOFK, with speeds of 15-20 kts anticipated at KOMA/KLNK later this afternoon. Winds will once again slow tonight, shifting southwesterly before increasing in speed out of the northwest before sunrise tomorrow as a wind shift passes through. Short- term models suggest that we may have some light rain chances (20%) pass through with or shortly behind the wind shift, but they will remain out of the TAFs until confidence increases.
