LONG TERM...Sunday through Thursday

The weak upper level trough will slowly move across the Great Basin with differences in the positioning of the trough. A 30-50 percent chance of precipitation continues on Sunday before tapering off to 10-20 percent by Monday. The AI models have the trough further north than the rest of the ensembles which would keep precipitation going into Tuesday before the system moves east into Utah. Current forecast does not account for the AI solutions. Upper level ridging returns on Tuesday ahead of the next cold front that arrives on Wednesday. Current forecast POPs from the NBM and WPC are not high enough for Wednesday and Thursday with this trough moving inland.
