...DRY CONDITIONS WITH ABOVE NORMAL TEMPERATURES INTO NEXT WEEK...

.METEOROLOGICAL CONDITIONS (FRI AM - THU AM)...

High pressure is centered over the vicinity of the 4-Corners region 
and has expanded its reach westward over CA and NV this morning. At 
the same time...general troffing exists over the northeast Pacific 
extending from an upr low spinning near 50N/140W. Through the 
weekend...the area of high pressure will strengthen and reach near 
6000-meters at 500-mb while also drifting just a tad to the west. 
Over the northeast Pacific...the offshore low pressure system will 
rotate inland across BC and the Pacific Northwest...which may help 
keep temperatures in check just a bit over the far northern portion 
of the area on Sunday and Monday. Then for much of next week...the 
area of high pressure will continue to meander near the 4-Corners 
region...while a weaker disturbance moves toward Vancouver Island on 
Wednesday. This s/wv trof doesn/t look to have much impact on the 
area. Overall...through the upcoming week...expect temperatures to 
fluctuate anywhere from plus 5- to plus 15-degF over seasonal 
normals...except the immediate coast where marine influences will 
keep temperatures closer to average for this time of year.

Freezing levels currently running anywhere from 15000-feet near 
Crater Lake to 18500-feet near Point Conception will stay in this 
general range through much of the upcoming week.
