NOT MUCH CHANGE FROM PREVIOUS FORECAST REGARDING FRONT FIRST HALF OF TUESDAY. KEEP THUNDER CHANCES IN THE MOUNTAINS WHERE BEST LOW LEVEL INSTABILITY WILL RESIDE. FOR TEMPS MONDAY...LEANED HEAVILY ON WARMER MEX GUIDANCE WITH UPPER 70S TO AROUND 80F DEPICTED IN THE LOWLANDS.

QPF WISE...THIS SYSTEM LOOKS TO CARRY AROUND A QUARTER OF RAIN POTENTIAL WITH IT. EVERY LITTLE BIT WILL BE WELCOMED THOUGH...PARTICULARLY IN THE N MOUNTAINS WHERE IT HAS BEEN UNUSUALLY VERY DRY OVER THE PAST FEW WEEKS.
