SYNOPSIS

Issued at 312 AM CST Sat Nov 22 2025

H5 analysis tonight had a split flow regime across the CONUS. Broad west to east flow extended from British Columbia, east to the Canadian Maritimes. Within this flow, a shortwave trough was located along the Saskatchewan/Manitoba border with a closed low located along the Ontario/Quebec border. A trough extended south of this feature into the eastern Great Lakes. Further south, a decent shortwave trough was located over central Missouri. Further west, a closed low was located approximately 300 miles southwest of San Diego. At the surface tonight, high pressure was located over south central Nebraska. Winds were gradually turning to the southwest and were under 10 MPH. Skies were generally mostly cloudy to cloudy south of a line from Oshkosh to O'Neill. North of this line, skies were partly cloudy to clear. Temperatures as of 2 AM CT ranged from 35 degrees at Ogallala to 44 degrees at North Platte.

SHORT TERM /THROUGH SUNDAY/

Issued at 312 AM CST Sat Nov 22 2025

Conditions will be relatively quiet across the forecast area over the next 36 hours. Surface high pressure will continue to build south of the area into Kansas before sunrise into the morning hours. Winds will shift from the southwest to west by mid morning. This will force drier air into the forecast area from the west, and will end the threat for fog in the south and southeastern forecast area by daybreak. Clouds will also shift south and east of the area today as the surface high builds into Kansas and Oklahoma. With westerly winds in place and mainly sunny skies today, highs will reach into the upper 50s to around 60 across the area. A second surface high will build into the Sandhills overnight tonight. This will lead to light winds, and with clear skies in place, lows will reach into the mid to upper 20s across the area. Currently, the latest HRRR and NAM12 surface visby products, keep the greatest threat for fog well off to the south of the forecast area. This is also supported by the latest SREF ensemble visibility forecast which has the best threat for fog over Kansas into Missouri. That being said, will forgo mention of fog for tonight with this forecast package. Sunday will start out dry and mostly clear. Highs will reach into the upper 50s to around 60 with increasing southerly winds toward the latter half of the day. An upper level low, will cross northern Arizona, entering central Colorado by 00z Monday. Mid and high level cloudiness will increase late Sunday afternoon across southwestern Nebraska, however, current forecast trends keep this cloudiness south of the area until after peak heating, so the inherited temp forecast appears on track.

LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/

Issued at 312 AM CST Sat Nov 22 2025

The upper level low will track from central Colorado into southwestern Nebraska and northwestern Kansas Sunday night. Beginning Sunday evening, the threat for precipitation will increase across southwestern Nebraska. This threat will spread to the northeast into the overnight, persisting through the first half of Monday. Forecast QPF's are light with this system and the latest NBM ensembles indicate less than a 50% chance for QPF>0.10" and less than a 20% chance for QPF>0.20". By Monday afternoon, conditions will dry out over the western half of the forecast area. Highs will reach the middle to possibly upper 50s over far southwestern areas. By Monday night, a northern stream low and trough will track across southern Canada. This will force a strong cold front through the forecast area Monday night. Behind the front, there is some mid level forcing which tracks across South Dakota on Tuesday leading to light snow. Some of this snow may eventually approach the NE/SD state line Tuesday afternoon. The NBM forecast initialized some slight chance pops over far northern areas Tuesday afternoon and this seems plausible given the latest deterministic GFS and EC solns. The pattern will amplify across the CONUS midweek with a broad trough of low pressure in the east and ridging in the west. Northwesterly flow across the central CONUS will lead to dry, but cool, conditions across the forecast area through Friday. Daily highs will be mainly in the 40s with some 30s in the northeastern forecast area.
