What a difference a day makes!  Sunday’s model runs indicated a strong cold front on Saturday but recent models prog this feature to move through the area on Monday, especially the ECMWF.  This appears due to the handling of the northern jet stream and a shortwave trof progged to drop southeast out of Canada at the end of the period.  The ECMWF is likely the better solution, but lucky for me the strong cold front is at D8.

There isn’t much to talk about this week.  Semi-permanent ridge will remain in-place across the eastern Pacific again this week allowing for moderate temperatures and Friday looks very nice across the state.  Several shortwave trofs will move across the state but none of them are expected to have enough moisture to cause any problems.  As such, the drought continues and see little relief in-sight.  GFS total QPF (384 hr) looks very low.

Followed NAM MOS through Thursday and GFS Friday/Saturday.  I did go with OUN on Sunday to account for a possible backdoor cold front.  I’m not believing the GFS’s surface pattern, but going with lower temperatures isn’t a bad thing.  If the ECMWF verifies, Monday will be colder.  GFS 384 hr run shows the eastern Pacific ridge to remain in-place the entire period.  At this point I see no reason to go with POPs but I’m not stupid enough to go all pops zero either.
