NORTHWEST WINDS HAVE DEVELOPED THIS AFTERNOON, WITH THE
STRONGEST OBSERVATIONS OF GUSTS UP TO AROUND 30 MPH FOUND MAINLY
IN NORTH CENTRAL NORTH DAKOTA. WINDS ARE EXPECTED TO WEAKEN

DISCUSSION
ISSUED AT 250 PM CST WED FEB 26
CURRENTLY, SURFACE HIGH PRESSURE LOCATED IN UTAH, IS INFLUENCING
THE NORTHERN GREAT PLAINS. ALOFT, A RIDGE IS BUILDING IN THE
WESTERN CONUS. TODAY WILL BE WARMER THAN YESTERDAY WITH MOSTLY
SUNNY SKIES.
THURSDAY THE RIDGE FLATTENS OUT OVER THE NORTHERN
PLAINS AS A CLIPPER SYSTEM MOVES IN THURSDAY EVENING. THURSDAY
WILL BE OUR WARMEST DAY WITH THE RIDGE SLIDING SLIGHTLY EAST.
WE WILL SEE HIGHS IN THE LARGELY IN THE 50S SOUTH AND WEST OF
THE RIVER. WITH THIS CLIPPER, A COLD FRONT PASSAGE WILL ALSO
OCCUR FRIDAY MORNING. THIS WILL CRATE A SLIGHT CHANCE OF SNOW IN
THE NORTHEAST ALONG THE FRONT. WINDS WILL ALSO BE VERY STRONG.
A STRONG PUSH OF COLD AIR ALONG THE FRONT AND THE PRESSURE
GRADIENT OFF THE LOW WILL CREATE THESE WINDS. THE CHALLENGE WITH
THIS IS THE FACT THAT THE COLD PUSH OF AIR AND TIGHT PRESSURE
GRADIENT LOOKS ONLY STRONG FOR A FEW HOURS. FOR THIS REASON WE
HAVE NOT PUT OUT A WATCH OR ADVISORY YET. THE STRONGEST WIND
PUSH LOOKS TO OCCUR BETWEEN 12Z AND 18Z, MAINLY IN THE JAMES
RIVER VALLEY. SLIGHTLY COOLER AIR WILL MOVE IN, BUT STILL A
LITTLE ABOVE AVERAGE, ON THE BACK SIDE OF THE CLIPPER THROUGH
SATURDAY. LOW TEMPERATURES IN THE NORTHEAST COULD BE SINGLE
DIGITS SATURDAY MORNING.
SUNDAY THE RIDGE REFORMS, ALLOWING THE 20 DEGREE ABOVE AVERAGE
TEMPERATURES TO RETURN THROUGH MONDAY. IN THIS NORTHWEST FLOW,
MULTIPLE LITTLE WAVES WILL MOVE THROUGH, LEADING TO CHANCES (30
PERCENT) OF RAIN EARLY NEXT WEEK. MONDAY THE FLOW COULD TURN
SOUTHWEST WITH SOME MORE SHORTWAVES. HIGHS AFTER MONDAY WILL DIP
AGAIN BACK TO THE 30S, WHICH IS STILL AROUND AVERAGE.
AVIATION /00Z TAFS THROUGH 00Z THURSDAY/
ISSUED AT 945 PM CST WED FEB 26 2025
VFR CEILINGS AND VISIBILITY ARE ANTICIPATED AT ALL TERMINALS

WINDS WILL GENERALLY DIMINISH THROUGH THE EVENING AND OVERNIGHT
INTO MONDAY. WITH A CLIPPER SYSTEM PASSING THROUGH THE NORTHERN
PLAINS THROUGH THE END OF THE WORKWEEK, WINDS ARE EXPECTED TO
TURN TO THE WEST-SOUTHWEST AND STRENGTHEN THROUGH THE DAY
THURSDAY, BECOMING GUSTY WITH SPEEDS UP TO 20 MPH AND GUSTS UP
TO 30 MPH BY THE END OF THE TAF PERIOD. ALONG WITH THIS, LLWS IS
EXPECTED TO DEVELOP ACROSS THE NORTH BY THE MID THURSDAY AFTERNOON,
