AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BOISE ID
303 AM MST SUN DEC 16 2012

.SHORT TERM...TODAY THROUGH MONDAY...SIGNIFICANT WINTER STORM
TO IMPACT THE MOUNTAINS TONIGHT THROUGH MONDAY. WINTER STORM
WARNING HAVE BEEN ISSUED FOR OUR NORTHERN ZONES.

AT 09Z...COLD FRONT NEAR BAKER CITY AND ROME AND IS ON SCHEDULE TO
REACH BOISE AROUND 5 AM MST. PRE-FRONTAL BAND OF SNOW SHOWERS JUST
EAST OF MOUNTAIN HOME AND WILL CONTINUE TO PUSH EASTWARD EXITING
THE FORECAST AREA BY 4 AM MST. RADAR SHOWING A FEW SNOW SHOWERS
ACROSS THE AREA THOUGH NO ADDITIONAL SNOWFALL IS EXPECTED. AS OF 2
AM MST...THE BOISE AIRPORT MEASURED 0.5 INCHES OF SNOW. WILL
EXPIRE CURRENT WINTER WEATHER ADVISORIES ON TIME.

A BRIEF BREAK IN THE PRECIPITATION LATER THIS MORNING AS THE NEXT
STRONGER SYSTEM QUICKLY APPROACHES THE COAST. THIS SYSTEM WILL
BRING SIGNIFICANT SNOWFALL AND WIND TO THE MOUNTAINS BEGINNING
TONIGHT. ASSOCIATED WARM FRONT REACHES OUR SOUTHERN ZONES AROUND
18Z TODAY BACKED BY STRONG 170 KTS UPPER JET AND SIGNIFICANT
MOISTURE PLUME. WARM FRONT QUICKLY PUSHES NORTH TONIGHT WITH
INCREASING SOUTHWEST WINDS SETTING THE STAGE FOR A SIGNIFICANT
OROGRAPHIC SNOW EVENT IN THE WEST CENTRAL AND BOISE MOUNTAINS...AS
WELL AS BAKER COUNTY...UPPER WEISER RIVER AND CAMAS PRAIRIE. EXPECT
6 TO 10 INCHES OF SNOW AT MCCALL WITH OVER A FOOT SNOW ON BANNER
SUMMIT FROM SUNDAY NIGHT THROUGH MONDAY. BREEZY SOUTH-
SOUTHWESTERLY WINDS WILL CAUSE BLOWING AND DRIFTING SNOW
ESPECIALLY DURING THE OVERNIGHT PERIOD WHEN THE SNOW RATIOS WILL
BE HIGH /LESS MOISTURE CONTENT IN THE SNOW/. AS FOR BAKER
COUNTY...BELIEVE THE BAKER VALLEY WILL BE SHADOWED THROUGH MUCH
OF THE EVENT HOWEVER...HIGH ELEVATION ROADS WILL SEE WINTER STORM
CONDITIONS. TREASURE VALLEY WILL BE SHADOW THROUGH MUCH OF THE
EVENT FOR LITTLE TO NO PRECIPITATION EXCEPT WITH THE WARM FRONTAL
PASSAGE BETWEEN 5 PM AND 8 PM TONIGHT. SOUNDING PROFILES SUGGEST
PRECIP TYPE WILL START OUT AS SNOW THEN BECOME A MIX OF RAIN AND
SNOW ENDING AS ALL RAIN. LIGHT SNOW ACCUMULATION IN GRASSY AREAS
/LESS THAN HALF AN INCH ACCUMULATION/ INITIALLY...MELTING BY LATE
EVENING WILL HAVE MINIMAL IMPACT FOR TRAVEL. THIS WILL BE THE BEST
CHANCE FOR PRECIPITATION IN THE TREASURE VALLEY. HEAVY SNOW FOR
NORTHERN ZONES CONTINUES THROUGH MONDAY SLOWLY TAPERING OFF MONDAY
AFTERNOON WITH A WEAK COLD FRONTAL PASSAGE. PLEASE SEE WINTER
WEATHER PRODUCTS /WSWBOI/ FOR MORE DETAILS ON THIS EVENT.

.LONG TERM...MONDAY NIGHT THROUGH SATURDAY...COLDER AIR WILL FUNNEL
INTO THE REGION MONDAY NIGHT AS A COLD FRONT DRAPED ALONG THE ID/NV
BORDER PUSHES SOUTHWARD. SNOW SHOWERS WILL LINGER MONDAY
NIGHT...ESPECIALLY ALONG THE NEVADA BORDER WHERE LIGHT SNOW
ACCUMULATIONS ARE POSSIBLE. AN UPPER TROUGH FOLLOWS IN BEHIND THE
FRONT TUESDAY FOR COLDER TEMPERATURES AND A CHANCE OF SNOW SHOWERS.
THE TROUGH PUSHES EAST TUESDAY NIGHT FOLLOWED BY A WARM FRONT AND
UPPER RIDGING ON WEDNESDAY. PRECIP WILL BE IN THE FORM OF SNOW WITH
THE WARM FRONT...ALTHOUGH STILL NOT SURE AT THIS TIME AS TO AMOUNT
OF QPF SINCE THE ECMWF SHOWS LITTLE QPF WHILE THE GFS SHOWS SOME
MODEST AMOUNTS. FOR NOW WILL FORECAST A CHANCE OF SNOW SHOWERS
FOCUSED TO THE NORTH AND WEST OF THE TREASURE VALLEY. FOR THE
REMAINDER OF THE WEEK...MODELS STILL AGREE ON A GULF OF ALASKA LOW
PRESSURE SYSTEM DIGGING OFF THE PACNW COAST. PREVIOUSLY...THE MODELS
KEPT OUR AREA UNDERNEATH A RIDGE BUT THE LATEST RUNS HAVE TRENDED TO
A SOLUTION OF MOIST SOUTHWEST FLOW ACROSS THE AREA. THIS FLOW WOULD
FAVOR OROGRAPHIC PRECIP OVER THE MTNS WITH LESSER AMOUNTS IN THE
VALLEYS. IT STILL APPEARS THAT TEMPS WILL BE SLIGHTLY ABOVE NORMAL.

&&

.AVIATION...BAND OF IFR CONDITIONS IN SNOW WILL EXIT TO THE EAST BY
12Z. HOWEVER...EXPECT SCATTERED VALLEY MVFR CONDITIONS IN RAIN/SNOW
SHOWERS AND NUMEROUS IFR-MVFR CONDITIONS IN MTN SNOW SHOWERS THIS
MORNING. WIDESPREAD IFR CONDITIONS IN SNOW WILL MOVE BACK INTO SE
OREGON THIS AFTERNOON WHILE SCATTERED VALLEY/NUMEROUS MVFR
CONDITIONS IN SNOW SHOWERS CONTINUE IN SW IDAHO. SURFACE WINDS TO 15
KNOTS WITH WESTERLY WINDS ALOFT TO 30 KTS AT 10K FEET MSL.
