PREV DISCUSSION
SHORT TERM...TONIGHT THROUGH SUNDAY NIGHT...A WEAK WAVE TODAY
IS CARRYING A BAND OF CLOUDS THROUGH. PRECIPITATION UNLIKELY,
THOUGH VIRGA IS POSSIBLE AT ALTITUDE IN THE BAND. THE CLOUDS
SLIGHTLY REDUCED OUR WARMING TODAY, DROPPING THE TEMPERATURE
FORECAST FOR THE NEXT FEW DAYS. EITHER WAY, HIGH PRESSURE WILL
CONTINUE TO BUILD AND THIS WEEKEND WILL STILL BE HOT AND DRY.
HIGH TEMPS REACH ABOUT 15 DEGREES ABOVE NORMAL, WITH AFTERNOON
MINIMUM RHS IN THE TEENS FOR VALLEYS AND LOW 20S FOR MOUNTAINS.
LONG TERM...MONDAY THROUGH FRIDAY... THE UPPER LEVEL RIDGE AXIS
WILL PASS OVERHEAD MONDAY, ALLOWING SW FLOW ALOFT TO MOVE INTO
THE AREA. MONDAY AND TUESDAY SHOULD BE THE HOTTEST DAYS AT
AROUND 15 DEGREES ABOVE NORMAL. THERE IS A CHANCE OF SHOWERS
AND A SLIGHT CHANCE OF THUNDERSTORMS IN SE OREGON MONDAY NIGHT.
TUESDAY AND TUESDAY NIGHT, WITH THE SW FLOW WELL-ESTABLISHED
AND A SHORTWAVE TROUGH APPROACHING, THERE IS A BETTER OF SHOWERS
AND THUNDERSTORMS AREAWIDE. THIS CHANCE EXTENDS INTO WEDNESDAY
MAINLY ON THE IDAHO SIDE AS THE SHORTWAVE MOVES THROUGH EARLY
IN THE DAY, AND REMAINS THERE THURSDAY AND FRIDAY. MODELS SHOW
ANOTHER SHORTWAVE OR TWO MOVING THROUGH THURSDAY AND/OR FRIDAY,
BUT CONFIDENCE IS NOT HIGH CONCERNING THE TIMING. TEMPERATURES
WILL DECREASE AFTER TUESDAY, WITH READINGS AROUND 10 DEGREES
ABOVE NORMAL WED, THEN FALLING TO JUST 2-4 DEGREES ABOVE NORMAL
THURSDAY AND FRIDAY.
