SYNOPSIS
HIGH PRESSURE RETURNS THURSDAY INTO THE SATURDAY, WITH A DRIER
AND WARMER WEATHER. UNSETTLED WEATHER RETURNS TO THE REGION
NEXT WEEK.
DISCUSSION
TODAY THROUGH SATURDAY: TODAY IS COOL, DRY, AND BREEZY UNDER THE
INFLUENCE OF A HIGH PRESSURE RIDGE BUILDING IN THE PACIFIC
NORTHWEST. TEMPERATURES WILL PEAK IN THE UPPER 40S TO LOWER 50S.
DESPITE COOL TEMPERATURES, DEW POINTS IN THE 10S TO 20S ARE
RESULTING IN RHS AROUND 20-40%. THIS BUILDING RIDGE WILL BRING THE
RETURN OF ABOVE NORMAL TEMPERATURES (UPPER 50S) TOMORROW AND DRY
CONDITIONS WILL PERSIST THROUGH SATURDAY.
SUNDAY THROUGH THURSDAY: THERE IS GOOD AGREEMENT OF A SHORTWAVE
TROUGH BRINGING LIGHT MOUNTAIN SNOW TO THE MOUNTAINS, PRIMARILY IN
THE CASCADES SUNDAY NIGHT INTO MONDAY. AMOUNTS LOOK LIGHT AS PRE-
FRONTAL TEMPERATURES SUNDAY AFTERNOON ARE ABOVE FREEZING (WHICH IS
WHEN THE BEST PWATS AROUND 110-150% OF NORMAL ARE OVER THE
CASCADES). THERE IS SOME UNCERTAINTY OF THE TIMING OF THE FRONTAL
PASSAGE. IF THE TIMING OF THE FRONT WAS SLOWER INTO MONDAY MORNING
LIKE THE GFS, SNOW POTENTIAL INCREASES IN THE CASCADES.
PROBABILITIES FOR 2+" SUNDAY AFTERNOON THROUGH MONDAY AFTERNOON ARE
LOW FOR STEVENS PASS (35%) SO LITTLE IMPACTS ARE EXPECTED. THOSE
CHANCES DECREASE TO 25% FOR LOOKOUT PASS. WITH WESTERLY FLOW ALOFT,
CENTRAL AND EASTERN WA WILL BE IN THE RAIN SHADOW SUNDAY AND MONDAY.
NORTH IDAHO CAN EXPECT LIGHT BENEFICIAL RAINS AROUND 0.05" TO 0.25"
SUNDAY NIGHT THROUGH MONDAY AFTERNOON.
THE REST OF MONDAY THROUGH THURSDAY LOOKS UNSETTLED ESPECIALLY IN
THE MOUNTAINS. ENSEMBLE CLUTERS INDICATE NEARLY 80% OF MEMBERS
BRINGING ANOTHER SHORTWAVE TROUGH THROUGH THE REGION WEDNESDAY AND
THURSDAY, BRINGING BENFICIAL RAINS AND LIGHT MOUNTAIN SNOW. DB
