SYNOP:
Today and Tuesday will be dry with a warming trend. For Wednesday into early Friday, a trough of low pressure to the north will direct a flow of subtropical moisture into southwest California bringing periods of precipitation with higher snow levels. There is the potential for the precipitation to be heavy at times from late Wednesday into Thursday. A trough of low pressure to the north may continue chances for generally lighter precipitation for the weekend into early next week.

NWS LAS VEGAS SYNOP– (NORTH & EAST OF COUNTY)
Temperatures will be well below normal today under mostly sunny skies. There will be a slight warm up on Tuesday under increasing high clouds. Moisture associated with our next system will reach the southern Sierra Nevada Tuesday night. The moisture will continue to stream eastward across the region Wednesday and Thursday with good chances of mountain snow and valley rain.
