SHORT TERM...TODAY THROUGH THURSDAY
SEASONAL TEMPERATURES AND
HIGH PRESSURE PERSIST TODAY ALLOWING FOR MILD WEATHER CONDITIONS.
AN AREA OF LOW PRESSURE WILL TRACK ONSHORE CALIFORNIA TOMORROW AND
PUSH MOISTURE EASTWARD INTO WESTERN IDAHO BY THE END OF THE DAY.
AS THE LOW SLOWLY PROGRESSES FURTHER EASTWARD, INCREASING MOISTURE
IS FORECAST ACROSS OUR AREA ON THURSDAY. EXPECT INCREASED CLOUD
COVER HOWEVER FORECAST MODELS CONTINUE TO KEEP MOST OF THE
PRECIPITATION ASSOCIATED WITH THIS LOW TO OUR SOUTH. A STRAY
RAIN/SNOW SHOWER CAN'T BE RULED OUT ALONG THE IDAHO BORDER WITH
UTAH. LATE THURSDAY INTO FRIDAY, THE LOW WILL HAVE TRACKED INTO
UTAH. THIS NOW WILL BE THE BEGINNING OF INCREASED CHANCES FOR
PRECIPITATION ACROSS SE ID. NP/GK
LONG TERM
FRIDAY THROUGH TUESDAY. MODELS CONTINUE TO BRING IN
PRECIPITATION FRIDAY WITH THE GFS MORE WIDESPREAD THAN THE
EUROPEAN MODEL. MODELS ROTATE CLOSED UPPER LOW NORTH WITH THE
FRIDAY SYSTEM AND FOR NOW DID NOT COMPLETELY BITE OFF ON IT BUT
DID RAISE PRECIPITATION CHANCES WITH SNOW LEVELS RISING TO 7
THOUSAND FEET. A SECOND PACIFIC SYSTEM BRINGS IN A CHANCE FOR MORE
PRECIPIATION OVER THE WEEKEND WITH SNOW LEVELS STARTING OUT AT
AROUND 7 THOUSAND FEET SATURDAY AND POTENTIALLY DROPPING TO 4500
TO 5000 FEET SUNDAY BEHIND A COLD FRONTAL PASSAGE. EXPECT HIGH
TEMPERATURES NEAR NORMAL FRIDAY AND SATURDAY THEN DROPPING BELOW
NORMAL SUNDAY. SHOULD HAVE DRY CONDITIONS IN SOUTHERLY FLOW MONDAY
AND TUESDAY WITH WARMING TEMPERATURES. GK
