Marine Weather and Tide Forecast for Cozad, NE

DISCUSSION
Issued at 334 PM CDT Tue May 20 2025

Today through Thursday...

Breezy conditions are expected to stick around for the next few hours as northwest winds peak between 25 to 35 mph, occasionally gusting as high as 40 to 45 mph. Winds will quickly drop off through the rest of the evening, becoming 10-15 mph overnight. Besides the winds, PoPs for Wednesday afternoon have come up some (up 5-10%) to 15-25% as a few scattered brief showers with a few pop up thunderstorms could slide into parts of the area. Confidence remains on the lower end to the potentially limited coverage of these storms.

Temperatures will remain on the chilly side for the next two nights (mid 30s to mid 40s) from the help of mostly clear skies and a northwest to northerly persisting cool air advecting flow. Isolated to patchy areas of frost may be possible for a few lower lying areas primarily across Valley as well as far northwestern parts of Dawson, Sherman and Greeley counties Thursday morning. Highs for Wednesday and Thursday will top off in the upper 60s to mid 70s, generally as warm as it will get before at least Tuesday.

Synoptically, surface pressure will continue to raise as the low exits eastward, allowing winds to settle down (10-20 mph), remaining out of the northeast to northerly direction. Gusts in the afternoon could still peak up to 25 mph Wednesday. The mid-to-upper level jet will flatten out (zonal pattern), hugging the KS/NE state line through Thursday. A few upstream short-wave trough disturbances will begin to brew across the Western U.S., bringing a few precipitation chances with it into the holiday weekend.

Friday into next week...

A more consistent trend in the global models (GFS/ECMWF) within the last few runs show a signal for multiple rounds of precipitation over the extended weekend. The first wave of precipitation could arrive as early as Friday morning (30-55%) followed by a lull in the later afternoon and early overnight hours. A broader and more consistent coverage of precipitation (45-60%) returns Saturday and Sunday, with fluctuating off-and-on chances ahead of a more pronounced secondary system.

A few thunderstorms could be mixed in, though the severe potential remains questionable given the currently projected lower than ideal instability (CAPE values < 1,000J). The better potential would lie towards the south where both dewpoints and instability may be higher.
Despite an elongated period of PoP chances, this event will likely not be considered what one would call a washout. We await more details that can add more confidence to our forecast amounts within the next few days.

Temperature-wise, things are favored to stick just a hair below normal (75-78 degrees) as highs plateau across the low 60s to mid 70s through next Tuesday. Winds should primarly range between 10 to 20 mph, starting southeasterly Friday afternoon and slowly turning towards the northeast by Sunday.
