AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE POCATELLO ID
331 AM MDT SUN AUG 11 2013

.DISCUSSION...CURRENT WATER VAPOR IMAGERY SHOWS AN UPPER LEVEL LOW
OFF THE OREGON COAST SLOWLY LIFTING NORTH. THIS IMAGERY ALSO
SHOWS AN DRY SSW DRY SLOT MOVING OVER EXTREME SE IDAHO. MODELS
CONTINUE TO SHOW ISOLATED TO SCATTERED THUNDERSTORMS OVER THE
CENTRAL MOUNTAINS. EXPECT SMALL HAIL AND OUTFLOW WINDS OF AROUND
40 MPH IN AROUND THUNDERSTORMS. LOOK FOR DRY CONDITIONS AND BREEZY
WINDS FOR THE REST OF OUR AREA TODAY. EXPECT TEMPERATURES ABOVE
NORMAL FOR TODAY.

MONDAY THE PACIFIC LOW DRIFTS NORTH OVER VANCOUVER ISLAND. LOOK
FOR A REPEAT OF AFTERNOON THUNDERSTORMS OVER THE CENTRAL MOUNTAINS
IN SOUTH SOUTHWEST FLOW. WINDS WILL REMAIN BREEZY BUT LIGHTER THAN
SUNDAY.

TUESDAY THE PACIFIC LOW MOVES NORTH. HOWEVER MODELS CONTINUE TO
SHOW INSTABILITY IN SOUTHWEST FLOW BRINGING THUNDERSTORMS OVER THE
CENTRAL MOUNTAINS. WINDS ARE STILL SLIGHTLY ELEVATED BUT WILL BE
LIGHTER THAN MONDAY.

WEDNESDAY AND THURSDAY HIGH PRESSURE RIDGING STRENGTHENS OVER THE AREA
BRINGING DRIER CONDITIONS AND RELATIVELY LIGHT WINDS. EXPECT
TEMPERATURES WELL ABOVE NORMAL PARTICULARLY ON THURSDAY.

BY FRIDAY LOOK FOR ELEVATED WINDS AND AFTERNOON THUNDERSTORMS
CHANCES TO RETURN AS A SYSTEM APPROACHES FROM THE PACIFIC
NORTHWEST AND MONSOONAL MOISTURE CREEPS UP FROM THE SOUTH.
SATURDAY EXPECT BREEZY TO MODERATE WINDS AND MOUNTAIN
THUNDERSTORMS AS A SYSTEM MOVES THROUGH THE AREA.

.AVIATION...A LOW PRESSURE SYSTEM WAS NOTED LIFTING NORTH ALONG THE
OREGON COAST THIS MORNING WITH A DRY SSW FETCH OVER SE IDAHO.
NUMERICAL MODELS CONTINUE TO HIGHLIGHT THE POTENTIAL FOR AFTERNOON
THUNDERSTORM ACTIVITY NORTH OF A SUN VALLEY TO MACKAY LINE. FAIRLY
DRY AND BREEZY CONDITIONS ARE ANTICIPATED SOUTH OF THIS LINE TODAY.

HUSTON

.FIRE WEATHER...A LOW PRESSURE SYSTEM WAS NOTED LIFTING NORTH ALONG
THE OREGON COAST EARLY THIS MORNING WITH A FAIRLY DRY
SOUTH-SOUTHWEST FETCH LIFTING INTO SE IDAHO. NUMERICAL MODELS
CONTINUE TO SUGGEST THE POTENTIAL FOR THUNDERSTORM ACTIVITY NORTH OF
A SUN VALLEY TO MACKAY LINE TODAY WHILE DRY AND BREEZY CONDITIONS
ARE ANTICIPATED SOUTH OF THIS LINE TO THE UTAH BORDER. THUS...RED
FLAG WARNINGS HAVE BEEN POSTED FOR THUNDERSTORM POTENTIAL ACROSS
FIRE ZONE 475 THIS AFTERNOON/EVE AND GUSTY WINDS/LOW HUMIDITY FOR
FIRE ZONES 422 476 410 427 AND 413. THE UPPER LOW IS EXPECTED TO
DRIFT FURTHER NORTH TO A POSITION OFF VANCOUVER ISLAND MONDAY.
TRAILING DISTURBANCES IN THE SOUTH-SOUTHWEST FLOW ARE EXPECTED TO
HELP TRIGGER AFTERNOON CONVECTION ACROSS THE SALMON MOUNTAIN REGION
ONCE AGAIN MONDAY AFTERNOON. THERE IS A BIG QUESTION AT THIS TIME AS
TO THE AMOUNT OF COVERAGE EXPECTED. BOTH THE GFS AND NAM MODELS
PLACE THE STRONGEST ACTIVITY ALONG A LINE FROM CNTRL OREGON TO
HAMILTON MONTANA CONSISTENT WITH THE LOW MOVING FURTHER NORTH. THE
NAM MODEL HOWEVER...IS FLASHING FAIRLY WIDESPREAD COVERAGE WHICH
INCLUDES THE CENTRAL IDAHO FWX ZONES 475 AND A GOOD PORTION OF 422
AND 476 MONDAY AFTERNOON/EVE. LIKE THE IDEA OF THE FOCUS SHIFTING
FURTHER NORTH BUT WILL CONTINUE TO EVALUATE POTENTIAL FOR ONGOING
CONVECTIVE WARNINGS ACROSS THE CENTRAL MOUNTAINS. BY TUESDAY...A
PACIFIC LOW BEGINS TO MOVE TOWARD THE NW COAST WHILE THE FAIRLY
UNSTABLE SW FLOW PATTERN CONTINUES ACROSS THE CNTRL MOUNTAINS INTO
WRN MONTANA. AS THE LOW APPROACHES THE COAST WEDNESDAY...THE RIDGE
EXPANDS FURTHER NORTH ACROSS THE IDAHO PANHANDLE AND WRN MONTANA
POSSIBLY PROVIDING A BREAK FROM THUNDERSTORM ACTIVITY THROUGH AT
LEAST THURSDAY. BY FRIDAY...THE TROUGH SWINGS INTO THE COAST WITH
INCREASING SW FLOW ALOFT ACROSS IDAHO AND A BREAK DOWN OF THE 500MB
RIDGE WHICH MEANS INCREASING WIND AND INSTABILITY AND LIKELY AN
INCREASE IN FIRE ACTIVITY. FOR THE SECOND NIGHT IN A ROW...THE GFS
IS FLASHING A DRY FRONTAL PASSAGE SOMETIME SATURDAY
AFTERNOON/EVENING. HUSTON
