CLOUDY SKIES ACROSS THE REGION THIS EVENING WITH A FEW SHOWERS
OVER NORTHEAST NEBRASKA. THESE SHOWERS HAVE DEVELOPED ALONG A
WEAK BOUNDARY STRETCHING ALL THE WAY NORTHWEST TOWARD RAPID
CITY. THESE WILL CONTINUE TO MOVE NORTH-NORTHEAST. THE SYSTEM WE
ARE WATCHING MORE CLOSELY IS A STRONG UPPER-LEVEL TROUGH OVER
COLORADO. THIS WILL BRING THE SHOWERS FROM WESTERN KANSAS
NORTHEAST INTO EASTERN NEBRASKA AND WESTERN IOWA OVERNIGHT AS
THE CLOSED LOW WEAKENS AND GETS ABSORBED INTO A STRONGER UPPER-
LEVEL WAVE DROPPING SOUTH OUT OF ALBERTA/SASKATCHEWAN. RAINFALL
WILL CONTINUE ACROSS OUR AREA THROUGH THURSDAY MORNING ENDING
THROUGH THE AFTERNOON AS STRENGTHENING NORTHERLY WINDS BRING IN
DRY AIR.
THURSDAY NIGHT INTO EARLY FRIDAY WE ARE MONITORING THE POTENTIAL
FOR STRONG WINDS GUSTING 40 TO 50 MPH. AS THE WAVE MOVING OUT OF
CANADA PHASES WITH THE DECAYING SYSTEM OVER THE NORTHERN PLAINS,
WE SEE THE RIDGE OVER THE WEST COAST TRY AND ADVANCE. THIS LEADS
TO STRENGTHENING OF THE PRESSURE GRADIENT OVER THE GREAT PLAINS
BETWEEN THESE TWO SYSTEMS. A BROAD SWATH OF STRONG NORTHERLY
WINDS DEVELOPS OVER THE REGION INCLUDING EASTERN NEBRASKA AND
WESTERN IOWA. NBM GUIDANCE SHOWS AROUND A 60% CHANCE OF WINDS
GUSTING ABOVE 45 MPH OVER NORTHEAST NEBRASKA FRIDAY MORNING.
COULD START AS EARLY AS 3AM, BUT MORE LIKELY TOWARD 6AM THROUGH
11AM. WINDS WEAKEN GOING INTO FRIDAY AFTERNOON AS THE TROUGH
SHIFTS EASTWARD AND THE GRADIENT STARTS TO RELAX, THOUGH GUSTY
WINDS WILL LIKELY CONTINUE UNTIL AROUND 6PM.
WITH WINDS BECOMING CALM, CLEAR SKIES, AND A MUCH COOLER
CANADIAN AIR MASS IN PLACE, CONDITIONS WILL BE IDEAL FOR STRONG
RADIATIONAL COOLING OVERNIGHT FRIDAY INTO EARLY SATURDAY. WE
EXPECT TEMPERATURES TO FALL INTO THE LOW 30S WITH A FAIRLY
WIDESPREAD RISK FOR FROST. ONLY SPOTS THAT MIGHT NOT GET COOL
ENOUGH FOR FROST MAY BE IN OUR MORE URBAN AREAS OF OMAHA,
COUNCIL BLUFFS, AND LINCOLN.
AS THE RIDGE CONTINUES TO TREK EASTWARD ACROSS THE CENTRAL CONUS
OVER THE WEEKEND, WE'LL SEE SOUTHWESTERLY FLOW MOVE BACK IN
SATURDAY TRENDING TEMPERATURES WARMER OVER THE WEEKEND INTO
NEXT WEEK. MEANWHILE, THE UPPER-LEVEL PATTERN REMAINS ACTIVE. A
WEAK DISTURBANCE MOVES THROUGH ON MONDAY, THOUGH THERE WON'T BE
ENOUGH MOISTURE FOR MORE THAN AN INCREASE IN CLOUD COVER THROUGH
THE DAY. A STRONGER TROUGH DEEPENS ALONG THE WEST COAST EARLY
NEXT WEEK. THIS SYSTEM WILL STRENGTHEN SOUTHWEST FLOW AS IT
APPROACHES MIDWEEK BRINGING TEMPERATURES BACK INTO THE LOW-TO-
MID 70S FOR HIGHS ON TUESDAY AND WEDNESDAY. THIS SYSTEM BRINGS
OUR NEXT CHANCES FOR SHOWERS AND STORMS WEDNESDAY-FRIDAY NEXT
WEEK.
AVIATION /06Z TAFS THROUGH 06Z FRIDAY/
ISSUED AT 1155 PM CDT WED OCT 14 2026
MVFR TO IFR CONDITIONS WILL PREVAIL THROUGH THE MAJORITY OF THE
PERIOD, AS SHOWERS CONTINUE TO OVERSPREAD THE REGION. WHILE A
FEW RUMBLES OF THUNDER CAN'T BE RULED OUT, ANY WEAK STORMS
SHOULD BE FEW AND FAR BETWEEN. NORTHERLY WINDS WILL INCREASE
THURSDAY AFTERNOON AND EVENING AS SHOWERS MOVE OUT. EXPECT
SPEEDS OF 15 TO 20 KTS, WITH GUSTS UP TO 35 KTS POSSIBLE. LOWER
CEILINGS AND VISIBILITIES ARE EXPECTED TO IMPROVE TO VFR BY
AROUND 00Z THURSDAY EVENING.
