End Of Day Look At Morning WRF Forecasts - 19 December

By 4 pm MST this afternoon some clouds were starting to come in from the southwest - above.

Forecasts of total precipitation through 8 am MST on Saturday the 21st - WRF-NAM above and WRF- GFS below. The GFS version appears to be wetter than the NAM version, particularly over eastern Pima County and across north-central Arizona.

 The QPF forecast from NWS Tucson this morning appears a bit wetter than either of the model forecasts - below.

Finally, below is the surface forecast from the WRF-GFS valid at 10 am MST tomorrow morning - looks like a fairly dismal start to the day.
