SHORT TERM
(THIS EVENING THROUGH WEDNESDAY NIGHT)
ISSUED AT 249 PM CST TUE NOV 19 2024
COOLER WEATHER RETURNS TO THE FOUR STATE REGION STARTING THIS WEEK
AS A FRONTAL BOUNDARY ARRIVES TOMORROW. ONGOING TROUGHING ACROSS
THE UPPER GREAT PLAINS WILL SHIFT EASTWARD INTO THE MIDWEST
THROUGH THE MIDDLE OF THE WEEK, WITH THE BOTTOM OF THE TROUGH AXIS
VEERING MID-LEVEL FLOW FROM SOUTHWESTERLY, TO ZONAL, THEN TO
NORTHWESTERLY WITH THE ATTENDANT FRONTAL BOUNDARY AND POST-FRONTAL
AIR MASS USHERED IN. THIS WILL ALLOW FOR NORTHWESTERLY WINDS AND
NEAR-TO-BELOW NORMAL TEMPERATURES TO ARRIVE TOMORROW WITH
MAXIMUMS/MINIMUMS IN THE MID-TO-UPPER 60S/UPPER 30S TO LOWER 50S,
RESPECTIVELY. /16/.
LONG TERM
(THURSDAY THROUGH NEXT MONDAY)
ISSUED AT 249 PM CST TUE NOV 19 2024
DRY AND NEAR-SEASONABLE CONDITIONS WILL CONTINUE THROUGH MOST OF
THE WEEKEND BEFORE WARMER WEATHER RETURNS. THIS IS DUE TO LARGE-
SCALE RIDGING, EMERGING FROM THE INTERMOUNTAIN WEST, THAT
WEAKENS/FLATTENS ACROSS THE AREA BY SUNDAY, WHILE SURFACE RIDGING
SHIFTS EAST OF THE MISSISSIPPI RIVER VALLEY ALLOWING FOR MORE
ROBUST SOUTHERLY WINDS. SUBSEQUENT MOISTURE ADVECTION WILL BOOST
TEMPERATURE MAXIMUMS/MINIMUMS FROM NEAR-NORMAL TO WELL ABOVE
NORMAL WITH UPPER 70S/LOWER 80S AND LOW-TO-MID 60S AS THE MIDDLE
OF NEXT WEEK (AND THE NEXT CHANCE OF PRECIPITATION) APPROACHES.
