NORTHERN GREAT BASIN FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ELKO NV
220 PM PDT WED SEP 12 2001

.SYNOPSIS...THE LOW PRESSURE SYSTEM OVER NORTHERN CALIFORNIA
WILL CONTINUE TO MOVE TOWARDS THE NORTHEAST. THIS WILL RESULT IN A
DECREASE IN SHOWERS AND THUNDERSTORMS TONIGHT. ON THURSDAY ONLY A FEW
LINGERING SHOWERS WILL OCCUR NEAR THE IDAHO AND OREGON BORDERS.
ANOTHER LOW PRESSURE SYSTEM WILL BRUSH THE FAR NORTH MONDAY AND
TUESDAY FOR A SMALL THREAT OF SHOWERS.

.DISCUSSION...UPPER LOW CENTERED NEAR SACRAMENTO WILL CONTINUE TO
MOVE TOWARDS THE NORTHEAST. THIS WILL ALLOW DRIER AIR WORKING
AROUND THE BASE OF THE SYSTEM TO MOVE INTO NORTHERN AND EAST CENTRAL
NEVADA RESULTING IN A DECREASE IN SHOWERS AND THUNDERSTORMS TONIGHT.
ON THURSDAY ENOUGH LINGERING MOISTURE AND INSTABILITY WILL CONTINUE
ACROSS THE FAR NORTH FOR ISOLATED SHOWERS AND THUNDERSTORMS. SHORT
WAVE NEAR 35N/145W WAS INITIALIZED TOO WEAK BY ALL THE MODELS. IF
THIS SYSTEM DIGS FAR ENOUGH SOUTH IT COULD DRAW UP SOME MOISTURE FROM
TROPICAL STORM IVO INTO OUR FORECAST AREA OVER THE WEEKEND. WILL
HAVE TO WAIT TO SEE HOW THIS DEVELOPS. FOR NOW WILL GO ALONG WITH THE
MODEL IDEA OF BRINGING THIS SHORT WAVE INTO NORTHWEST NEVADA ON
SATURDAY WITH ONLY ENOUGH MOISTURE FOR PARTLY CLOUDY SKIES. MODELS
BRUSH THE NORTH WITH ANOTHER SHORT WAVE IN THE MONDAY/TUESDAY TIME
FRAME SO WILL CONTINUE WITH A SLIGHT CHANCE OF SHOWERS IN THE FAR
NORTH.
