SATELLITE IMAGE SHOWS LOW CLOUDS CONFINED TO THE
ROGUE, ILLINOIS, SCOTT, KLAMATH RIVER, SHASTA VALLEYS, AND
PORTIONS OF THE UMPQUA BASIN THIS MORNING. THE LOW CLOUDS AND
NEVER BROKE OUT IN THE ILLINOIS AND ROGUE VALLEY YESTERDAY AND
IT'S POSSIBLE IT DOES NOT BREAK OUT AGAIN IN THESE AREAS TODAY,
BUT THERE'S ENOUGH EVIDENCE TO SUGGEST THE LOW CLOUDS SHOULD BURN
OFF EARLY THIS AFTERNOON AND HAVE TRENDED THE FORECAST IN THAT
DIRECTION. ALSO HAVE NOT SEEN ANY REPORTS OR WEB CAMS SHOWING FOG
AND HAVE REMOVED IT FROM THE FORECAST. THE EXCEPTION WILL BE IN
THE SCOTT AND SHASTA VALLEYS, WHERE FOG IS PRESENT, BUT THE FOG
SHOULD LIFT TO A LOWER OVERCAST TOWARDS MIDDAY.
IT WILL BE DRY TODAY THROUGH THE WEEKEND AND STRONG UPPER RIDGING
REMAINS IN PLACE. THIS MEANS A CONTINUATION OF DRY AND STABLE
CONDITIONS, THEREFORE WE WILL LIKELY HAVE A REPEAT OF LOW CLOUDS
AND PERHAPS FOG IN THE SAME AREAS AS THE LAST COUPLE OF DAYS.
