AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PORTLAND OR 330 AM PDT TUE JUL 13 2004 .SYNOPSIS...AN UPPER LEVEL TROUGH OF LOW PRESSURE WILL REMAIN OVER THE NORTHEAST PACIFIC THROUGH THE NEXT SEVERAL DAYS...WITH SOUTHERLY FLOW OVER THE REGION. THE SOUTHERLY FLOW WILL BRING SEVERAL WEAK WEATHER SYSTEMS NORTHWARD OVER THE AREA...AND ONSHORE FLOW WILL KEEP TEMPERATURES CLOSE TO NORMAL THROUGH FRIDAY. CONDITIONS WILL REMAIN SOMEWHAT UNSTABLE OVER THE HIGHER ELEVATIONS FOR A CONTINUED THREAT OF AFTERNOON THUNDERSTORMS OVER THE CASCADES. THE UPPER TROUGH WILL APPROACH THE COAST...INCREASING THE CHANCES FOR PRECIPITATION THIS WEEKEND. && .DISCUSSION SHORT TERM...BUSY MORNING WITH THUNDERSTORMS MOVING NORTH OVER THE FORECAST AREA. DOPPLER HAS INDICATED SEVERE CONDITIONS SEVERAL TIMES WITH ONE CELL IN PARTICULAR...AND GROUND TRUTH FROM A LATE NIGHT SPOTTER BEARS OUT THE DOPPLER ALARMS. VORT MAX ASSOCIATED WITH CURRENT CONVECTION SHOULD LIFT ACTIVITY NORTH INTO WASHINGTON DURING THE MORNING HOURS...BUT MODELS CONTINUE TO SHOW INSTABILITY OVER THE CASCADES TODAY. FEEL THAT CHANCES ARE BEST OVER THE NORTHERN OREGON/SOUTHERN WA CASCADES FOR LATER IN THE AFTERNOON BUT WILL CONTINUE SLIGHT CHANCE ALONG THE CENTRAL CASCADES CREST AS WELL...CONFIDENCE ISNT ENOUGH TO REMOVE.
