Issued at 352 AM CDT Sun Sep 22 2024 At 3 am CDT, a cold front was analyzed across south central Kansas through northwest Kansas. A closed upper low was located over Colorado. Scattered light rain showers were ongoing across northeast Colorado into far southwest Nebraska. Temperatures ranged from 41 at Gordon to 57 at Ogallala. && .SHORT TERM /THROUGH MONDAY/... Issued at 352 AM CDT Sun Sep 22 2024 A positively tilted upper low centered over Colorado early this morning will become stretched across south central Nebraska this afternoon. This will support showers chances today mainly across Chase, Hayes and Frontier County, with a slight chance as far north as I80. Skies will remain mostly cloudy across the south today, with skies becoming mostly sunny across north central Nebraska. Raised highs today to the upper 60s north central to the low to mid 60s southwest. Tonight, skies will become clear. A ridge of surface high pressure will extend from Wisconsin and Iowa back through central and eastern Nebraska and western Kansas. A light and variable wind across central and southwest Nebraska with a light southwest wind to develop across the northwest Sandhills. Favorable radiational cooling will drop widespread lows in the upper 30s to near 40. Colder temperatures as low as 35-36 degrees expected across portions of the southeast panhandle, into west central and southwest Nebraska. Went with the colder NBM 25th percentile for lows. Even so, the probability for lows below 36 degrees remain below 50 percent. Have continued the mention for patchy frost, but the need for a Frost Advisory remains unlikely. Monday, will see a nice warmup ahead of an upper trough moving into the Dakotas. This will bring a weak cold front into the northwest Sandhills late afternoon. Highs to reach into the upper 70s near and west of a Valentine through Ogallala line to near 72 across the far southeastern zones. Sunny skies, except for afternoon clouds increasing across the northwest Sandhills. && .LONG TERM /MONDAY NIGHT THROUGH SATURDAY/... Issued at 352 AM CDT Sun Sep 22 2024 The upper trough will drop southeast across Nebraska Monday night. This continues to support a slight chance for showers across the west. may lead to a small threat for precipitation in western portions of the forecast area. Sprinkles are possible further east across the remainder of the forecast area. Tuesday through Saturday, a dry forecast is likely as a cutoff low develops and persists over the mid and lower Mississippi Valley and an upper ridge builds into the Central and Northern Plains. Temperatures may remain near normal in the low to mid 70s across the southeastern zones, to above normal in the upper 70s/lower 80s across the west and northwest. This is due to the influence of the cutoff low forecast to persist across the mid and lower Mississippi Valley. Lows will generally be in the upper 40s to lower 50s which is slightly above normal for this time of year. && .AVIATION /18Z TAFS THROUGH 18Z MONDAY/... Issued at 1233 PM CDT Sun Sep 22 2024 Skies will gradually clear this evening at the KLBF and KVTN terminals. In the meantime, expect broken ceilings around 15000 FT AGL at the KLBF terminal and 20000 FT AGL at the KVTN terminal through mid evening.
