NEGATIVELY TILTED TROUGH BEGINS TO MOVE INLAND SUNDAY NIGHT WITH MODELS SHOWING QUITE A BIT OF MOISTURE AND UPWARD FORCING. WILL CONTINUE TO FORECAST AT LEAST LIKELY POPS OVER THE ENTIRE FORECAST AREA UNDER THIS SCENARIO ALTHOUGH IT LOOKS LIKE THE BEST PRECIPITATION WILL BE SOUTH. STILL SOME UNCERTAINTY HOW MUCH PRECIPITATION WILL FALL WITH THIS SYSTEM AS PRECIPITABLE WATER VALUES NOT VERY IMPRESSIVE. WILL HOLD OFF ON ISSUING ANY WATCHES OR ADVISORIES FOR NOW BUT SPRING MOUNTAINS COULD END UP WITH A PRETTY DECENT AMOUNT OF SNOW IF THINGS COME TOGETHER JUST RIGHT. TROUGH AXIS MOVES TO NEAR THE CA/NV BORDER MONDAY WHICH SHOULD RESULT IN DECREASING CHANCES OF PRECIPITATION FOR THE WESTERN PART OF THE FORECAST AREA. STILL LOOKING AT A DECENT AMOUNT OF MOISTURE WRAPPING UP INTO AZ AND MUCH OF SOUTHERN NV THOUGH SO WILL KEEP LIKELY POPS THERE.
