HIGH PRESSURE WILL KEEP THE REGION SUNNY INTO
SATURDAY. MOISTURE INCREASES ON SUNDAY OVER EASTERN NEVADA FOR
SCATTERED SHOWERS AND POSSIBLE THUNDERSTORMS, CONTINUING THROUGH
TUESDAY.
SHORT TERM
TONIGHT THROUGH SATURDAY.
ALTHOUGH NOT DISCERNIBLE, FORECAST AREA REMAINS ON THE BACK SIDE
OF UTAH CLOSED LOW CIRCULATION, MEANING LIGHT DRY NORTHERLY FLOW
PREVAILS. UTAH CLOSED LOW IS EXPECTED TO SHEAR EASTWARD ON FRIDAY,
BUT BLOCKING PATTERN OVER THE WEST COAST STATES PERSISTS THROUGH
THE SHORT TERM, WITH A HIGH OVER LOW PATTERN (RIDGE OVER THE
PACIFIC NORTHWEST AND SPINNING LOW ALONG THE SOCAL COAST). IN THE
SHORT TERM, HIGH PRESSURE OVER THE PACIFIC NORTHWEST BRINGS DRY
SUBSIDENT AIR INTO NEVADA.

THE SOCAL LOW DRIFTS TOWARD NEVADA AND DRAWS UP MOISTURE INTO EAST
CENTRAL NEVADA BEGINNING SATURDAY NIGHT, BUT BECOMES MORE
PROMINENT ON SUNDAY THAT AFFECTS EASTERN NEVADA. BY SUNDAY
AFTERNOON AND EVENING, SCATTERED SHOWERS WILL AFFECT AREAS SOUTH
AND EAST OF THE RUBY MOUNTAINS WITH A GOOD PORTION OF WHITE PINE
COUNTY RECEIVING SOME SHOWERS. WITH THE BLOCKING PATTERN OVER THE
WESTERN STATES, THE UPPER LOW WILL BE SLOW TO GET KICKED OUT OF
THE REGION. AT THIS TIME, TIME FRAME OF DEPARTURE COULD BE TUESDAY
EVENING OR WEDNESDAY. UNSETTLED WEATHER FOR EASTERN NEVADA MAY
PERSIST INTO TUESDAY. FOR AREAS WEST OF ELKO AND EUREKA, MOSTLY
DRY WEATHER CAN BE EXPECTED WITH POSSIBLE LIGHT SHOWERS OVER THE
HIGHER TERRAIN.
BLOCKING PATTERN COULD BREAK DOWN BY NEXT WEDNESDAY OR THURSDAY
WITH THE MAIN WESTERLIES PUNCHING ACROSS THE PACIFIC NORTHWEST.
PACIFIC MOISTURE STREAMS ACROSS WASHINGTON AND OREGON INTO IDAHO,
BUT SOME OF THIS MOISTURE SKIRTS ACROSS THE NORTHERN FRINGE OF
