DISCUSSION
ISSUED AT 319 PM CDT THU OCT 30 2025
TODAY THROUGH SATURDAY:
WATER VAPOR IMAGERY THIS AFTERNOON FEATURES A POTENT MID/UPPER
TROUGH CONTINUING TO SPIN OVER THE EASTERN CONUS WHILE NORTHWESTERLY
FLOW CONTINUES TO USHER A MID-LEVEL VORTICITY MAXIMUM FROM
SASKATCHEWAN/MANITOBA INTO THE UPPER MISSISSIPPI VALLEY. A COLD
FRONT ASSOCIATED WITH THAT DIVING VORT MAX HAS HELPED SWEEP
THIS MORNING'S FOG AND LOW STRATUS OUT, ALLOWING WESTERLY TO
NORTHWESTERLY WINDS TO GUST ACROSS CENTRAL NEBRASKA WHERE
SUNSHINE AND DEEPER MIXING HAVE BEEN IN PLACE LONGER WHILE
SCATTERED CLOUDS CONTINUE ACROSS FAR EASTERN NEBRASKA AND IOWA.
STEEPER LOW-LEVEL LAPSE RATES HAVE ALLOWED FOR SOME RETURNS TO
SHOW UP IN THE DEEPER CLOUD FIELDS, EVAPORATING QUICKLY AND
RESULTING IN VIRGA TO BE VISIBLE UNDERNEATH TALLER CLOUDS. WINDS
WILL SLOW THIS EVENING BUT SHOULD NOT FALL TO ZERO OVERNIGHT --
KEEPING ADDITIONAL MENTIONS OF FOG OUT OF THE FORECAST. WITH
LAST NIGHT'S FREEZE AND PREVIOUS COOLER NIGHTS SO FAR THIS
SEASON, WE'VE ENDED THE ISSUANCE OF FROST/FREEZE WATCHES,
WARNINGS AND ADVISORIES FOR THE SEASON.
HIGH TEMPERATURES WILL BE TRENDING LOWER FOR FRIDAY AND SATURDAY AS
THE EASTERN TROUGH RELOADS WITH THE DIVING VORT MAX AND ALLOWS FOR
THE AXIS OF THE JET STREAM TO MOVE SOUTH OF THE FORECAST AREA. CAMS
AND MODEL SOUNDINGS HAVE BEEN HINTING AT ADDITIONAL STEEP LAPSE
RATES DEVELOPING/MOVING IN FRIDAY EVENING THROUGH SATURDAY MORNING
WITH JUST ENOUGH MOISTURE TO BE ON THE LOOKOUT FOR FLURRIES WITH NO
ACCUMULATIONS EXPECTED. AS OF RIGHT NOW, THE MOSTLY LIKELY PLACE TO
SEE ANY FLAKES FLY WILL BE ACROSS FAR NORTHEAST NEBRASKA WHERE LESS
EROSION OF THE LOW-LEVEL MOISTURE IS EXPECTED TO TAKE PLACE.
SUNDAY AND BEYOND:
WITH THE LONGWAVE TROUGH EXITING TO THE EAST OF THE AREA EARLY
SUNDAY, EASTERN NEBRASKA AND IOWA WILL BE IN FOR A PATTERN CHANGE AS
THE BUILDING RIDGE TO THE WEST PUSHES WARMER CONDITIONS EASTWARD.
EXPECT HIGHS TO CLIMB INTO THE 60S SUNDAY FOR EASTERN AND CENTRAL
NEBRASKA WITH THE EXPECTATION THAT THEY SPREAD EASTWARD MONDAY
THROUGH THE WEEK. MODELS STRUGGLE TO OUTPUT ANY PRECIPITATION
WITH ANY MID-LEVEL IMPULSE THAT PASSES THROUGH THE ZONAL FLOW,
WITH OUR NEXT CHANCE FOR MEANINGFUL PRECIPITATION COMING IN THE
FORM OF A DEEPENING SHORTWAVE TROUGH THAT ARRIVES FRIDAY INTO
SATURDAY THAT APPEARS TO BE RAIN AT THIS TIME.
AVIATION /00Z TAFS THROUGH 00Z SATURDAY/
ISSUED AT 605 PM CDT THU OCT 30 2025

THE OVERNIGHT HOURS. A FEW HIGHER LEVEL CLOUDS WILL BEGIN
MOVING IN AGAIN FRIDAY MORNING. NORTHWEST WINDS THIS EVENING
WILL SHIFT TO THE WEST-NORTHWEST AROUND 02-04Z, BECOMING
NORTHWESTERLY AGAIN AFTER SUNRISE.
