STILL BE AROUND TO A COUPLE OF DEGREES ABOVE CLIMATOLOGY. FAIRLY
ZONAL FLOW SETS UP AFTER THE COLD FRONTAL PASSAGE BEFORE A STRONG
RIDGE ONCE AGAIN BEGINS TO BUILD OVER THE NORTHWEST BY THURSDAY.

AND HIGH LEVEL CLOUDS FROM THE WEST TOWARD THE EAST. COLD FRONT
MOVING INTO SOUTHEAST OREGON BY LATE AFTERNOON/EARLY EVENING IS
ALREADY PRODUCING SCATTERED THUNDERSTORMS. THUNDERSTORMS HAVE THE

NEAR 7000 CFS FOR THE NEXT SEVERAL WEEKS. INFLOWS INTO THE RESERVOIR
SYSTEM ABOVE LUCKY PEAK DAM HAVE BEEN INCREASING SLOWLY EACH DAY
WITH WARMER TEMPS AND INCREASED FREEZING LEVELS. HOWEVER... COOLER
SUN TEMPS 5-7 DEGREES BELOW TODAY/S LEVELS AND LOWERING FREEZING
LEVELS WILL SLOW RESERVIOR INFLOWS SLIGHTLY EARLY IN WEEK. IN
ADDITION...LOW DEW POINT TEMPS AND LACK OF WETTING RAIN WILL HELP
DRY SOILS IN VALLEYS FOR INCREASED IRRIGATION DEMAND. THE BOTTOM
LINE IS THAT THE CURRENT WEATHER PATTERN WILL KEEP NORMAL SNOW MELT
PATTERN WITH A PEAK NOT EXPECTED UNTIL MID OR LATE MAY.
