Dry But With Some Winds

View of Catalinas before sunrise shows high, thin clouds overhead this morning. The cirrus is coming in off the Pacific from weak disturbance west of southern California and Baja, as per IR below from 7:50 am MST.

The 06 UTC forecast from the WRF-GFS at Atmo (above) indicates a windy day for Christmas Eve - wind forecast above is valid at 9:00 am tomorrow morning.

Plumes from the GEFS at 06 UTC last night shown here: QPF above indicating dry until chances for sprinkles near end of year - sprinkles tomorrow now gone from current forecasts; 10-m wind speeds below are much weaker than the WRF forecasts for tomorrow - so will be interesting to observe which model is closer to what happens.

Plume for T indicate slight cooling tomorrow due to a weak front coming by. Rapid warming then until marked cooling next Tuesday and Wednesday.
