On Tuesday overnite into Wednesday a week clipper system will move through the area bringing, light rain fall totals and a few inches of snow down to the mountain passes.
After this system passes a large upper level high develops just to the west of us keeping us dry and models are showing it hanging on until around next Thursday
the image below shows the 12z GFS-WRF 500mb chart showing the high pressure on Thursday
watch as it continues on to Saturday
Along with it this will also bring very high snow levels up to around 7,000-8,000ft
The image below has the 18z GFS showing 850mb (5,000ft) temps
Temps are over 8c in the cascades
during this time a low level high develops to the east of us giving us light east winds, these winds will cause an inversion (warmer above then below) so daytime highs will only be in the 40s. While the lows in outlying areas will be down into the low 20s
