AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE POCATELLO ID
212 PM MDT MON SEP 5 2011

.SHORT TERM...MOISTURE CONTINUES TO SPREAD INTO OUR REGION AS
UPPER TROUGH OF LOW PRESSURE IS LIFTING OUT OF CALIFORNIA. CLOUD
COVER THIS AFTERNOON HAS KEPT TEMPERATURES A BIT LOWER THAN
FORECAST WHICH HAS DIMINISHED THUNDERSTORM DEVELOPMENT. CLEARING
IN NORTHEAST NEVADA WILL ALLOW SOME WARMING ALONG IDAHO / NEVADA /
UTAH BORDERS SO BETTER CHANCE OF LATE AFTERNOON DEVELOPMENT THERE.
OVERNIGHT INSTABILITY TO INCREASE AS LOW LIFTS OUT SO EXPECT SOME
ISOLATED THUNDERSTORMS OVER MOST AREAS. ON TUESDAY FOCUS WILL BE
IN THE SOUTHEAST HIGHLANDS AND THEN DRY OUT ON WEDNESDAY WITH
BRIEF HIGH PRESSURE RIDGING.

AS FAR AS IMPACTS...THE AMOUNT OF PRECIPITABLE WATER COMING INTO
THE AREA MAY AID IN SOME LOCALIZED DOWNPOURS. AREAS THAT HAVE
BURNED THIS SUMMER MAY BE SUSCEPTIBLE TO FLASH FLOODING AND WE
WILL MONITOR THIS.

.LONG TERM...FOR THE REST OF THE WEEK A RIDGE OF HIGH PRESSURE
BUILDS ALONG THE CANADIAN BORDER WHILE A SUB-TROPICAL FETCH BEGINS
TO SET UP ACROSS THE GREAT BASIN WHICH WILL EVENTUALLY TRANSPORT
MOISTURE AND INSTABILITY BACK INTO THE AREA WITH AFTERNOON
THUNDERSTORMS POSSIBLE THROUGH THE WEEKEND.  PRESTON

&&

.AVIATION...WIDESPREAD UPPER LEVEL CLOUD COVER HAS SUPPRESSED FURTHER
-TSRA ACTIVITY WITH VERY LIGHT SHOWERS SO FAR. THE CONVECTIVE
BUILD-UPS HAVE PRODUCED SOME WEAK GUSTY OUTFLOW AT KBYI AND EXPECT
THAT TO CONTINUE WITH MORE RADAR ECHOES UPSTREAM FOR THAT AIRDROME.
KPIH WILL ALSO HAVE SHOWERS AND THUNDERSTORMS CLOSE ENOUGH TO
WARRANT VICINITY REMARKS.  RAIN FALL AMOUNTS SHOULD CONTINUE VERY
LIGHT AND SEE NO IMPACT OTHER THAN LIGHTNING AND GUSTY OUTFLOW.
EXPECT CLEARING AFTER 06/09Z OF THE CIRRIFORM CEILING.  OUTSIDE OF
-TSRA AND -SHRA ACTIVITY...WIND WILL CONTINUE LIGHT.  KIDA AND KSUN
WILL LIKELY ESCAPE MOST OF THE CONVECTIVE THREAT.  MESSICK

&&

.FIRE WEATHER...LIGHTNING HAS BEEN SLOW TO DEVELOP BUT STILL
EXPECTING SOME TONIGHT AS WEAK LOW PRESSURE MOVES THROUGH NORTHERN
UTAH AND SOUTHERN IDAHO.  DISPATCH CENTERS VERIFIED FUEL CONDITIONS
FOR THEIR RESPECTIVE AREAS...THUS HAVE ISSUED LIGHTNING RED FLAG
WARNING ONLY FOR ZONE 412.  WILL ALSO CONTINUE RED FLAG WARNING FOR
HAINES INDEX OF 6 IN THE SALMON-CHALLIS NF ZONES.  THE FORECAST
AFTER WED NIGHT HAS A LOW CONFIDENCE AS THE UPPER LEVEL PATTERN IS
VERY WEAK.  CURRENTLY...GUIDANCE INDICATES VERY LITTLE CHANCE OF AN
UPPER LEVEL LOW CENTERED OVER SOUTHERN CALIFORNIA OF ENTRAINING
MOIST UNSTABLE AIR NORTHWARD AND INTO THE NORTHERN GREAT BASIN UNTIL
SUN.  HOWEVER...JUST YESTERDAY IT WAS DOING THAT BY FRI NIGHT.  THE
MOIST UNSTABLE AIR COULD PRODUCE LOCALLY HEAVY DOWNPOURS AND
MODERATE LIGHTNING ACTIVITY LEVELS DURING THE WEEKEND.  THE CURRENT
LOW IS BRING SOME MOISTURE TO BRING RELIEF TO THE VERY POOR
RECOVERIES...AT LEAST IN THE ZONES SOUTH OF THE SNAKE RIVER TONIGHT.
OUTSIDE OF THUNDERSTORM ACTIVITY...WIND WILL CONTINUE LIGHT EVEN
WITH THE LOW MOVING THROUGH TONIGHT.  MESSICK

&&

.PIH WATCHES/WARNINGS/ADVISORIES...
RED FLAG WARNING UNTIL 6 PM MDT THIS EVENING IDZ475-476.

RED FLAG WARNING FROM 6 PM THIS EVENING TO MIDNIGHT MDT TONIGHT
BELOW 6000 FEET FOR THE IDZ412.
