An Upper Level Low Pressure Trough (Shaded “U” shape with arrows) slides eastward to our northeast. Surface and upper level high pressure take over for  while. Toward the weekend we see increased Zonal Airflow (west to east) across Oregon. The graphics for days 1-3  show a frontal system approaching from the north. The graphics for Days 3-7  show a frontal system moving down from the north Tuesday, and still another frontal system coming from the northwest Thursday moving through Thursday night.

ADVISORIES:

• A RED FLAG WARNING IS IN EFFECT UNTIL 11 PM TONIGHT FOR THE CENTRAL MOUNTAINS OF OREGON AND THE LOWER COLUMBIA BASIN OF OREGON AND THE EAST SLOPES OF THE NORTHERN OREGON CASCADES.
• A FIRE WEATHER WATCH IS IN EFFECT FROM THIS AFTERNOON THROUGH THIS EVENING FOR GUSTY WINDS AND LOW RELATIVE HUMIDITY FOR THE EAST SLOPES OF THE CENTRAL OREGON CASCADES, THE EAST SLOPES OF THE NORTHERN OREGON CASCADES, THE CENTRAL MOUNTAINS OF OREGON, AND THE LOWER COLUMBIA BASIN OF OREGON.
• A FIRE WEATHER WATCH IS IN EFFECT FROM SUNDAY AFTERNOON UNTIL SUNDAY EVENING FOR THE WESTERN KLAMATH NATIONAL FOREST, THE KLAMATH BASIN, THE FREMONT-WINEMA NATIONAL FOREST, THE SOUTH CENTRAL OREGON DESERT INCLUDING THE BLM LAND IN EASTERN LAKE AND WESTERN HARNEY COUNTY.
• A HEAT ADVISORY IS IN EFFECT THROUGH 11 PM MONDAY FOR CENTRAL DOUGLAS COUNTY.
• A HEAT ADVISORY IS IN EFFECT UNTIL 10 PM TODAY FOR THE FOOTHILLS OF THE NORTHERN BLUE MOUNTAINS OF OREGON, THE FOOTHILLS OF THE SOUTHERN BLUE MOUNTAINS OF OREGON, AND CENTRAL OREGON.
• AN EXCESSIVE HEAT WARNING IS IN EFFECT THROUGH 11 PM TUESDAY FOR EASTERN CURRY COUNTY, JOSEPHINE COUNTY, AND JACKSON COUNTY.

HEALTH ADVISORIES:

• A RECREATIONAL HEALTH ADVISORY IS IN EFFECT FOR ALL OF LAKE BILLY CHINOOK. THE LAKE IS LOCATED ABOUT 12 MILES WEST OF MADRAS, OREGON. WATER MONITORING HAS CONFIRMED THE PRESENCE OF CYANOBACTERIA AND THE TOXINS THEY PRODUCE IN THE METOLIUS, DDSCHUTES, AND CROCKED RIVER ARMS OF LAKE BILLY CHINOOK. THE CYNOTOXIN CONCENTRATIONS FOUND CAN BE HARMFUL TO HUMANS AND ANIMALS. PEOPLE SHOULD AVOID SWIMMING AND HIGH-SPEED WATER ACTIVITIES LIKE WATER SKIING OR POWER BOATING IN AREAS OF THE LAKE WHERE CYNOTOXINS ARE IDENTIFIED. ALTHOUGH TOXINS ARE NOT ABSORBED THROUGH THE SKIN, PEOPLE WHO HAVE SKIN  SENSITIVITIES MAY EXPERIENCE A PUFFY RED RASH AT THE AFFECTED AREA. DRINKING WATER DIRECTLY FROM THE LAKE IS ESPECIALLY DANGEROUS. TOXINS V=CANNOT BE REMOVED BY ANY TECHNIQUE.
• A PERMANENT HEALTH ADVISORY REMAINS IN EFFECT FOR THE SOUTH UMPQUA RIVER BAR. POOLS IN THE BEDROCK ALONG THE RIVERS EDGE ARE KNOWN TO DEVELOP BLUE-GREEN ALGAE (CYANOBACTERIAL) BLOOMS THAT CAN BE HARMFUL TO PETS AND PEOPLE IF ACCIDENTAL INGESTION OCCURS. SIGNS HAVE BEEN POSTED ALONG SEVERAL ACCESS AREAS ALONG THE  RIVER.
