SLIGHTLY DRIER AIR WILL MOVE IN BRIEFLY OVERNIGHT BEFORE MOISTURE INCREASES AGAIN FOR WEDNESDAY INTO THURSDAY. .DISCUSSION...MADE NUMEROUS CHANGES TO THE FORECAST PACKAGE BASED ON ONGOING ACTIVITY IN THE NORTH. SOME HEALTHY AREAS OF CONVECTION SOME SPOTS. LATEST AVN SHOWS A WEAK VORT LOBE CLIPPING THE EXTREME NORTH THIS MORNING IN SOUTHWEST FLOW...LIKELY HELPING CONVECTION IN THE NORTH. PLENTY OF MOISTURE AND INSTABILITY IN PLACE FOR MOST OF THE DAY THOUGH WE SHOULD GRADUALLY DRY OUT FROM WEST TO EAST TONIGHT. EXPECT THIS MORNINGS CONVECTION ACROSS THE NORTH TO SLOWLY MOVE OFF TO THE EAST BUT LEAVE PLENTY OF RESIDUAL MOISTURE IN PLACE TO HELP GET CONVECTION GOING AGAIN THIS AFTERNOON...JUST SO LONG AS SUBSIDENCE BEHIND MORNING SHORT WAVE DOESNT CAP IT. 12Z RUC FORECASTS QUITE LOW LIFTED INDICES ACROSS THE AREA BY 00Z...AS LOW AS -6 OVER UINTAS.

WE SHOULD SEE ACTIVITY EARLY THIS EVENING ALTHOUGH DRYING SHOULD MOVE IN OVERNIGHT WITH THE HIGH BUILDING OVERHEAD BY WEDNESDAY MORNING. MOISTURE WILL INCREASE AGAIN WEDNESDAY INTO THURSDAY AS THE HIGH SHIFTS EAST AND PULLS MOISTURE IN FROM THE SOUTH. AT THE SAME TIME THE MODELS ARE STILL ADVERTISING A SHORT WAVE MOVING THROUGH THURSDAY...ONE THAT ROTATES AROUND THE SOUTHERN EDGE OF THE HIGH AND GETS CAUGHT UP IN SOUTHWEST FLOW.
