AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE POCATELLO ID
300 AM MST FRI DEC 25 2009

.SHORT TERM...TODAY THROUGH MONDAY.
STRATUS STILL THE MAIN SHORT TERM FORECASTING PROBLEM. STILL
PERSISTING IN PORTIONS OF THE SNAKE PLAIN AND EASTERN HIGHLANDS
BUT NOT AS WIDESPREAD EARLY THIS MORNING AS LAST TWO MORNINGS.
GENERALLY THINK THE STRATUS WILL CONTINUE TO DISSIPATE THROUGH
TONIGHT AS DOWN SLOPE FLOW IN SNAKE PLAIN BECOMES MORE ENTRENCHED
THROUGH THE PERIOD. AS STATED THIS IS MOST DIFFICULT PROBLEM AS
THE STRATUS HAVING BIG IMPACT ON LOW TEMPERATURE FORECASTS AS
WELL. FLOW ALOFT TRANSITIONS FROM STRONG NORTHERLY TO
NORTHEASTERLY THEN EAST BY SATURDAY AS UPPER HIGH DEVELOPS IN
SOUTHERN ALBERTA. SEE NO THREAT OF PRECIPITATION THROUGH MONDAY
OTHER THAN SOME FLURRIES OUT OF WHAT STRATUS REMAINS THROUGH TOMORROW.
TEMPERATURES WILL REMAIN GENERALLY BELOW SEASONAL NORMALS. 
GK

.LONG TERM...MONDAY NIGHT THROUGH FRIDAY.

FLOW TURNS MORE ZONAL NEXT WEEK WITH SEVERAL SHORTWAVE SYSTEMS 
COMING ASHORE. ALTHOUGH NONE APPEAR TO BE TOO SIGNIFICANT. MODELS 
WERE HINTING AT A STRONGER SYSTEM ARRIVING LATE NEXT WEEK HOWEVER 
THE 00Z EUROPEAN HAS BACKED OFF. STILL MAINTAIN SOME HIGHER CHANCES 
FOR LATE NEXT WEEK...BUT DID COME DOWN SOME. 

&&

.AVIATION...LOW STRATUS AND AREAS OF FOG ARE EXPECTED TO HANG AROUND 
THE SNAKE PLAIN TODAY. KIDA WILL HAVE THE MOST PROBLEMS AS THEY ARE 
DEEPER INTO THE MOISTURE. KBYI AND KPIH WILL BE ON THE EDGE TODAY.

&&

.PIH WATCHES/WARNINGS/ADVISORIES...
NONE.
