KEY MESSAGES

- Warming trend through Monday with highs in the low to mid 80s in the lower elevations. Cooler temperatures towards the mid to late week.

- Next possible weather system pushing towards the end of the week, with chances of mountain showers going up.

- Light diurnal winds prevail, with the exception of breezy winds in the Cascade gaps Tuesday and Wednesday.

DISCUSSION

Zonal/slight ridging continues to prevail the area, continuing the dry and clear pattern and will continue to do so through the next couple of days. The warming trend continues through Monday when highs peak in the low to mid 80s across the lower elevation areas. Winds will be mostly light and variable with diurnal winds with the exception of breezy winds developing in the Cascade gaps Tuesday and Wednesday.

Our next weather maker will occur in the late part of this week as a trough/shortwave off British Colombia pushes into the PacNW (30-50% chance). Models struggle how to handle the system as we get close to the weekend, as there's not a concise conclusion with clusters and guidance on timing and strength of the trough. Confidence is rather low (10-30%) that the lower elevation areas will see precipitation, while higher confidence is placed on the mountain regions (50-70% chance) by Friday and Saturday. For more in-depth with the clusters, 27% of members want to bring a wet pattern in the lower elevations by Friday afternoon with a stronger trough advertised, while that number jumps to around 70% for the areas in the mountains. Still time to monitor this system, but not expecting any significant impacts with this system at the time with plenty of time to monitor for any evolving details over the next few days.

AVIATION /12Z TAFS THROUGH 12Z MONDAY/

VFR conditions prevail through the period with light and variable winds. Dry conditions prevail with SKC to SCT conditions through the period. No CIG or VIS issues expected.
