AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BOISE ID
209 PM MDT TUE JUN 3 2025
SHORT TERM...TONIGHT THROUGH THURSDAY NIGHT
THE FORECAST AREA WILL REMAIN UNDER THE INFLUENCE OF DRY
NORTHWEST FLOW AS A STRONG UPPER LEVEL RIDGE REMAINS SITUATED
OFF THE COAST WHILE AN UPPER TROUGH EXTENDS FROM THE NORTHERN
PLAINS ACROSS THE GREAT BASIN. THE PRESSURE GRADIENT WILL RELAX
TOMORROW RESULTING IN CONSIDERABLY LESS WIND WHILE TEMPERATURES
BEGIN AN UPWARD TREND. OTHER THAN SOME PASSING HIGH CLOUDS AND
DIURNAL CUMULUS OVER THE HIGHER TERRAIN, MOSTLY SUNNY/CLEAR
CONDITIONS WILL PREVAIL.
LONG TERM...FRIDAY THROUGH TUESDAY
A STRONG UPPER LEVEL
RIDGE WILL BUILD INTO THE NORTHWEST REGION FRIDAY AND THROUGH
THE WEEKEND. THIS RIDGING IS EXPECTED TO BRING CONSIDERABLY HOT
TEMPERATURES ACROSS THE AREA LATER IN THE WEEKEND FROM SUNDAY TO
MONDAY, WITH A 5- 10% CHANCE OF 100 DEGREE HIGH TEMPERATURES IN
THE LOWER VALLEYS FOR BOTH DAYS. ON MONDAY AND TUESDAY, LONG-
RANGE GUIDANCES GENERALLY INDICATE A WEAK TROUGH MOVING ONTO THE
NORTHWEST COAST. THERE IS CONSIDERABLE UNCERTAINTY OVER THE
TIMING AND MAGNITUDE OF THIS TROUGH EARLY NEXT WEEK, BUT CURRENT
GUIDANCES PROJECT A SLIGHT (10- 20%) CHANCE OF AFTERNOON
SHOWERS AND THUNDERSTORMS TO THE AREA ON MONDAY AND TUESDAY,
MOSTLY IN HIGHER ELEVATIONS. BREEZY AFTERNOON WINDS ARE
GENERALLY EXPECTED THROUGHOUT THE LONG-TERM PERIOD.
