BANDS OF MOISTURE AHEAD OF THE TROF AXIS ARE PRODUCING AREAS OF SHOWERS OVER PORTIONS OF SOUTHWEST..CENTRAL...AND NORTH CENTRAL MT BUT SUSPECT LITTLE PRECIPITATION IS ACTUALLY REACHING THE GROUND AT THIS TIME GIVEN LACK OF OBSERVED RAINFALL SO FAR AND THAT NUMEROUS STATIONS STILL HAVE RELATIVE HUMIDITIES NEAR/BELOW 50 PERCENT AS OF 3AM.

THERE ARE TWO OTHER MARKED CHANGES FROM EARLIER MODEL SOLUTIONS...LESS TOTAL RAINFALL AND A MUCH EARLIER END TO THE PRECIPITATION. SITES THAT DO SEE RAINFALL WILL LIKELY ONLY RECEIVE A TRACE TO A FEW HUNDREDTHS OF AN INCH...WITH ONE TO TWO TENTHS POSSIBLE IN THE CENTRAL MTN RANGES.

WARMEST TEMPERATURES LOOK TO OCCUR MONDAY THROUGH WEDNESDAY OF NEXT WEEK WITH AFTERNOON TEMPERATURES NEAR 80 DEGREES FOR MANY LOCATIONS. THE RIDGE BEGINS TO WEAKEN LATE WEDNESDAY AND THURSDAY AS UPPER LEVEL ENERGY BEGINS TO MOVE IN FROM THE PACIFIC.
