DISCUSSION
ISSUED AT 1250 AM CST SAT NOV 22 2025
A VERY DIFFUSE FRONT SHOULD MOVE OFF THE COAST THIS MORNING AND BRING
AN END TO SCATTERED SHOWERS, ISOLATED THUNDERSTORMS AND AREAS OF
FOG. TEMPERATURES WILL BE SLIGHTLY LOWER THAN THEY HAVE BEEN THE
PAST SEVERAL DAYS, BUT STILL ABOVE SEASONABLE NORMS. THAT SAID,
DEWPOINTS AND CORRESPONDING RH'S SHOULD BE ON A DOWNWARD TREND...AT
LEAST INTO LATER ON SUNDAY WHEN SOUTHEAST WINDS RESUME AND BEGIN
DRAWING GULF MOISTURE BACK INTO THE REGION.
UPPER LOW OFF THE CA/BAJA COAST WILL LIFT INTO THE PLAINS EARLY
NEXT WEEK. LOOKS LIKE A SIMILAR TRAJECTORY OF THE LAST ONE,
WHEREAS THOUGH WE'LL SEE SOME HIGHER PW'S AROUND THE REGION,
OVERALL INSTABILITY DOESN'T LOOK VERY IMPRESSIVE AND THE PRIMARY
FORCING/DYNAMICS SHOULD BE SITUATED TO OUR NORTH. BUT WITH INCREASING
LARGE SCALE LIFT, WE'RE LOOKING FOR A BAND OF SHOWERS AND
ISOLATED TSTMS MAKE THEIR WAY INTO THE REGION MONDAY AFTERNOON AND
INTO TUESDAY.
RIDGE GRADUALLY AMPLIFIES TO OUR WEST AND FLOW ALOFT WILL
TRANSITION FROM THE SW TO THE NW...WHICH SHOULD ALLOW THE NEXT
COLD FRONT TO PUSH THROUGH TUESDAY NIGHT INTO WED MORNING...MAKING
WAY FOR NICE THANKSGIVING WX AND TEMPERATURES CLOSER, AND PROBABLY
EVEN BELOW, WHAT WOULD BE EXPECTED THIS TIME OF YEAR. 47

BUT WILL GRADUALLY BECOME N-NW AS THE FRONT SAGS FURTHER SOUTHWARD
