DISCUSSION
ISSUED AT 1039 PM MDT TUE SEP 29 2026
RAIN AND STORMS ASSOCIATED WITH THE REMNANTS OF POLO HAS MOSTLY
EXITED THE AREA BUT SOME LINGERING SHOWER ACTIVITY TONIGHT IS MOSTLY
ASSOCIATED WITH A LARGE UPPER LOW. THE CENTER OF THE UPPER LOW WILL
TREK EASTWARD THROUGH THE DAY WEDNESDAY BUT WILL ONLY BRING LIGHT
SHOWERY ACTIVITY TO THE AREA AS MUCH OF THE MOISTURE WILL BE PUSHED
OUT WHICH WILL ALSO KILL INSTABILITY. IN ADDITION, WINDS WILL BECOME
SLIGHTLY BREEZIER THAN WHAT WE'VE BEEN SEEING WITH WEST WINDS OF 15-
20 MPH. HEADING INTO THURSDAY, THE UPPER LOW WILL BE LIFTING OUT OF
THE SOUTHWEST CONUS AND INTO THE PLAINS BUT MODELS ARE CONSISTENTLY
TRYING TO SUGGEST SOME LINGERING ENERGY BEHIND THE TROUGH THAT MAY
OR MAY NOT PINCH OFF INTO IT'S OWN LOW. NOT MUCH TO SAY REGARDING
THE WEATHER RIGHT NOW HEADING INTO FRIDAY AND SATURDAY OTHER THAN
FRIDAY WILL BE SLIGHTLY BREEZY, CALM SATURDAY WITH CHANCES FOR LOW
END RAIN CHANCES FOR THE AREA MOUNTAINS, MORE PARTICULARLY FOR THE
SACRAMENTO MTNS. MORE BREEZY AFTERNOONS AHEAD FOR SUNDAY AND MONDAY.
