DISCUSSION
ISSUED AT 1201 PM CST SAT NOV 22 2025
A SHORTWAVE IS NOW MOVING EAST OF THE FA ALLOWING FOR DRY CONDITIONS
THROUGH THE REMAINDER OF THE WEEKEND. SFC HIGH PRESSURE WILL
BEGIN TO BUILD IN FROM THE WEST TONIGHT INTO SUNDAY, WITH
VISIBLE IMAGERY ALREADY SHOWING SKIES CLEARING ACROSS THE NORTH.
THE BOUNDARY LAYER WILL QUICKLY DECOUPLE TONIGHT WITH
RADIATIONAL COOLING, SUPPORTING PATCHY FOG THAT CAN BECOME
LOCALLY DENSE. GIVEN RESIDUAL WET GROUND CONDITIONS, MODEL
GUIDANCE MAY NOT BE AGGRESSIVE ENOUGH WITH THE POTENTIAL FOR FOG
DEVELOPMENT INTO SUNDAY MORNING.
THE REST OF SUNDAY WILL FEATURE AMPLE SUNSHINE WHILE MONDAY WILL
START OFF DRY WITH INCREASING CLOUDS AHEAD OF THE NEXT SYSTEM. HIGHS
WILL RANGE FROM THE UPPER 50S TO LOWER 60S BOTH DAYS. BY MONDAY
AFTERNOON, A 500 MB LOW CURRENTLY OVER THE SW CONUS WILL APPROACH
FROM THE CENTRAL PAINS AS A SHORTWAVE. INCREASING PVA COMBINED WITH
A WEAK AREA OF SFC LOW PRESSURE OVER EASTERN KANSAS AND WESTERN
MISSOURI WILL SUPPORT RAIN CHANCES MONDAY AFTERNOON INTO
TUESDAY MORNING. AS A SECONDARY AREA OF LOW PRESSURE DEVELOPS
OVER MINNESOTA, THERE STILL REMAINS SOME DISAGREEMENT AMONG
MODEL GUIDANCE IN HOW QUICKLY THE PRIMARY SYSTEM WEAKENS TUESDAY
MORNING. THE GENERAL ENSEMBLE CONSENSUS IS FOR 0.25 TO 0.75
INCHES OF QPF FROM NORTHWEST TO SOUTHEAST, WITH LOCALLY UP TO
1.00 INCH NEAR THE TN BORDER.
AFTER THE STORM SYSTEM CLEARS TUESDAY, A BROAD 500 MB TROUGH DIGS
ACROSS THE FA THROUGH THE LATTER HALF OF THE WEEK WITH A RIDGE OF
SFC HIGH PRESSURE BUILDING IN FROM CANADA. MUCH COOLER
TEMPERATURES 5 TO 10 DEGREES BELOW NORMAL CAN BE EXPECTED
THROUGH THANKSGIVING ALONG WITH TRANQUIL CONDITIONS. THE NEXT
CHANCE OF PCPN HOLDS OFF UNTIL THE FOLLOWING WEEKEND WHEN
ANOTHER FRONT IS PROGGED TO APPROACH IN THE SUNDAY TO MONDAY
PERIOD. UNLIKE THE FIRST SYSTEM, THERE MAY BE MORE MOISTURE AND
INSTABILITY TO WORK WITH ALONG A TIGHT BAROCLINIC GRADIENT.
