SOUTHWEST IDAHO/SOUTHEAST OREGON AREA FORECAST DISCUSSION 
NATIONAL WEATHER SERVICE BOISE IDAHO
220 PM MDT WED JUL 18 2001

BROAD TROF REMAINS ANCHORED OVER THE PACIFIC NORTHWEST WITH A SERIES 
OF WEAK EMBEDDED IMPULSES ROTATING THRU THE BASE OF THE TROF. THE 
STRONGEST OF THESE IS FORECAST TO AFFECT THE FORECAST AREA LATE 
THURSDAY AFTERNOON/ AND THURSDAY NIGHT WITH SCATTERED 
SHOWERS/THUNDERSTORMS FAVORING NORTHERN LOCATIONS. ANOTHER AREA TO 
WATCH WILL BE OVER THE NEVADA/IDAHO BORDER WHERE CONVECTIVE 
INSTABILITY IS INCREASING. OVERALL, EXPECT NOTHING MORE THEN 20/30 
POPS IN ANY AREA DURING THE NEXT TWO DAYS. MAIN STORY CONTINUES TO 
BE THE VERY COOL AND PLEASANT CONDITIONS OVER THE AREA WITH MOST 
LOCATIONS ENJOYING MID DAY READINGS IN THE 60S AND 70S. WITH A 
REINFORCING SHOT OF COOL AIR DROPPING SOUTHEAST ON THE NEXT WAVE 
THURSDAY, CONTINUED COOL AIR EXPECTED THROUGH SATURDAY IN THIS 
TROFFY COOL PATTERN. 

EXTENDED...WILL HAVE A CHANCE OF SHOWERS AND COOLER THAN NORMAL FOR 
SATURDAY AND SUNDAY AS TROF FINALLY BEGINS TO SLOWLY LIFT OUT. A 
RETURN TO MORE SEASONABLE WARM AND DRY WEATHER ARRIVES LATE SUNDAY 
AND RUNS THROUGH NEXT WEEK.  

.BOI...NONE.
