THE LOW OFF THE OREGON COAST GETS MOVED INTO THE SOUTHERN REGION OF
THE FORECAST AREA. THURSDAY NIGHT AND FRIDAY AS THE UPPER LOW DIGS
DOWN THE CALIFORNIA COAST...A 700 MB LOW DEVELOPS OVER CENTRAL IDAHO
AND TRACK NORTHEAST. THIS WILL BRING ANOTHER ROUND OF SHOWERS TO THE

DAY FOR US AS RIDGE PUMPS UP AHEAD OF NEXT TROF DIGGING OVER PACNW
COAST. WILL TAKE PRECIP OUT FOR SUNDAY. PROGS NOW FAVOR THE LOW
CUTTING OFF OVER NRN CALIFORNIA ON MON/TUE WITH ONLY MODEST COOLING
FOR US. STILL LOOKS POTENTIALLY WET EARLY NEXT WEEK AS MODELS HINTING
