AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE POCATELLO ID
1257 PM MDT THU SEP 5 2013

.DISCUSSION...THE UPPER LOW MOVING INTO SE OR THIS AFTN CONTINUES
TO STREAM MONSOON MOISTURE INTO ID. MORNING CONVECTION HAS MOVEF
OUT OF THE AREA...AND AFTERNOON CONVECTION IS EXPECTED TO START UP
AND SPREAD ACROSS SE ID CONTINUING INTO THE EARLY EVE. PW VALUES
AGAIN RUNNING ABOVE 1 INCH...SUPPORTING THE THREAT OF HEAVY RAIN
WITH THUNDERSTORMS. THE UPPER LOW MOVES SLOWLY NE TO CENTRAL WA ON
FRI...AND THIS WILL PUSH MUCH OF THE MOISTURE OFF TO THE N AND E
OF ID. ONLY EXPECTING SCATTERED SHOWERS AND TSTMS IN THE EASTERN
HIGHLANDS ON FRI AND SAT AND LESS COVERAGE ON SUNDAY. BY SUN NIGHT
THE UPPER LOW MOVES TO THE N CENTRAL MT. THIS WILL TAKE THE PRECIP
OUT OF THE AREA ENTIRELY...WITH UPPER RIDGING TAKING OVER AND
KEEPING THE AREA DRY THROUGH THURSDAY. HEDGES

&&

.AVIATION...MORNING SHOWERS AND THUNDERSTORMS ARE BEGINNING TO MOVE
OUT OF THE AREA WITH SKIES GENERALLY CLEARING SOMEWHAT.
HOWEVER...THIS WILL ACT TO DESTABILIZE THE ATMOSPHERE AND WILL GIVE
WAY TO MORE ORGANIZED CONVECTION THIS AFTERNOON. STORMS THIS
AFTERNOON WILL BE WELL DEVELOPED AND COULD PRODUCE STRONG OUTFLOW
WINDS. AIRMASS WILL STABILIZE LATE TONIGHT AND BRING MORE SETTLED
WEATHER TO THE AREA. HINSBERGER

&&

.FIRE WEATHER...CONCERN FOR THIS AFTERNOON AND EVENING WILL BE
TWO-FOLD...A CONTINUED FLASH FLOOD THREAT ACROSS THE AREA AND THE
SEVERE WEATHER POTENTIAL AS INDICATED BY THE SLIGHT RISK HIGHLIGHT
FROM SPC. MOISTURE WILL CONTINUE TO STREAM INTO THE AREA FROM THE
SOUTHWEST AHEAD OF AN UPPER LOW OVER THE OREGON COASTAL WATERS.
HEAVY RAINFALL MAY PRODUCE MUDSLIDES AND/OR DEBRIS FLOW OVER RECENT
BURN AREAS. THE UPPER LOW IS EXPECTED TO SLOWLY ADVANCE INLAND AND
SHOULD BE LOCATED OVER EASTERN WASHINGTON FRIDAY NIGHT. THIS SHOULD
HELP INTRODUCE SOME DRIER AIR TO THE CENTRAL MOUNTAINS HEADING INTO
THE WEEKEND...BUT MOISTURE WILL REMAIN OVER THE SOUTHEASTERN
HIGHLANDS THROUGH SUNDAY AS THE UPPER LOW CONTINUES EASTWARD. MODELS
SUGGEST A MUCH DRIER WEATHER PATTERN STARTING NEXT WEEK AS RIDGING
BUILDS BACK INTO THE AREA. EXPECT TO SEE LOWER HUMIDITY NEXT WEEK AS
A RESULT.  HINSBERGER
