DISCUSSION
ISSUED AT 235 PM CST TUE NOV 19 2024
THE STRONG LOW PRESSURE SYSTEM THAT MOVED THROUGH YESTERDAY IS
CURRENTLY STALLED OVER NORTHERN MINNESOTA, WITH A STRONG
PRESSURE GRADIENT GENERATING NORTHWESTERLY WINDS ACROSS EASTERN
NEBRASKA. THE STRONGEST WINDS ARE CLOSER TO THE LOW IN SOUTH
DAKOTA AND SOUTHWEST MINNESOTA, WHERE WIND ADVISORIES AND HIGH
WIND WARNINGS ARE IN EFFECT. TOMORROW (WEDNESDAY) WE'RE GOING
TO SEE THIS LOW STRETCH A BIT MORE SOUTHEAST BEFORE EXITING
EASTWARD, EXPANDING SOME OF THOSE STRONGER WINDS SOUTHEAST INTO
NORTHEAST NEBRASKA WHICH COULD SEE WINDS TO 50 MPH. ELSEWHERE
CROSS THE AREA, WINDS GUSTING TO 35 TO 40 MPH WILL BE LIKELY.
WITH NORTHWESTERLY WINDS ADVECTING IN COOLER, DRY AIR OVER THE
NEXT FEW DAYS, WE'LL SEE TEMPERATURES TREND DOWNWARD WITH HIGHS
ONLY IN THE 40S ON WEDNESDAY AND UPPER 30S TO LOW 40S ON
THURSDAY. WINDS WILL BE RELAXING THURSDAY INTO FRIDAY, ALLOWING
FOR EFFICIENT RADIATIONAL COOLING. THIS WILL DROP OVERNIGHT LOWS
INTO THE UPPER TEENS TO MID 20S ACROSS OUR AREA FRIDAY MORNING.
GOING INTO THE WEEKEND, WE'LL SEE A WEAK RIDGE BUILDING IN WITH
A RETURN OF SOUTHERLY FLOW AHEAD OF OUR NEXT SYSTEM THAT ARRIVES
SUNDAY. THIS WILL LEND TOWARD A RETURN OF ABOVE NORMAL
TEMPERATURES JUST IN TIME FOR WEEKEND ACTIVITIES. A DRY COLD
FRONT WILL SHIFT WINDS TO THE NORTHWEST ON SUNDAY BRINGING BACK
IN COOLER TEMPERATURES FOR EARLY NEXT WEEK.
THOSE MAKING PLANS FOR THANKSGIVING TRAVEL WILL WANT TO WATCH
THE LATTER HALF OF NEXT WEEK. MODELS HAVE BEEN IRRITATINGLY
INCONSISTENT WITH THE DETAILS OF THE FORECAST THAT FAR OUT, BUT
ENSEMBLES DO SHOW SOME POTENTIAL FOR WINTRY PRECIP SOMETIME
WEDNESDAY-FRIDAY. WITH SO MUCH UNCERTAINTY, SNOW LOVERS DON'T
GET YOUR HOPES TOO HIGH JUST YET.
