An interesting scenario coming up, with moisture remnants of previous hurricane Patricia move up as a extratropical everyday low pressure system.
There are big differences in the models here, with the GFS cranking out an inch or more of (much needed) rain, but with the NAM model having the moisture and heavy rain missing us and moving to our west. The NAM has high pressure blocking the rain and keeping the low pressure to our west.
With the NWS and TV forecasters predicting heavy rain for Wednesday, this will be a good test of the NAM vs GFS models for precipitation in the upcoming winter. In such similar discrepancies last winter, the drier NAM model was the winner. We’ll see.
The NAM model’s QPF values were more accurate than the GFS, with total precipitation less than 0.8 inches. Something to keep in mind with upcoming winter storms.
