Isolated Mountain Storms Eastern Arizona


Residual low-level moisture will support some isolated mountain thunderstorms over eastern Arizona. Above is 12 UTC WRF-NAM forecast of radar echoes valid at 3 pm MST this afternoon. We were in Phoenix yesterday, and there were visually impressive thunderstorms, in the distant northeast to east, during the late afternoon and evening. The models forecast a repeat today as a weak, 500 mb, short wave moves across the state. Further drying is forecast after today, Below is the 06 UTC WRF-NAM forecast of PW valid at 10 pm next Monday night - significant PW is pushed far south to Sinaloa and lower latitudes, so several very nice days on tap here.
