SHORT TERM...WEAK SURFACE COLD FRONT FROM THE NORTHWEST HAS NOT
COOLED TEMPS BUT NORTHWEST WINDS HAVE INCREASED...ESPECIALLY ON THE
IDAHO SIDE...DUE TO THE ASSOCIATED SHORT WAVE TROUGH ALOFT.  WINDS

MODEL TRIES TO MAKE A CASE FOR SOME ISOLATED CONVECTIVE SHOWERS IN

.SHORT TERM...TONIGHT THROUGH MONDAY. THE LATEST SATELLITE IMAGERY
CONTINUED TO SHOW A DEEP LOW PRESSURE SYSTEM OVER SRN COLORADO WHICH
WAS LIFTING SLOWLY NNE WITH TIME. FURTHER NORTH...A DISTURBANCE WAS
SHEARING EAST THROUGH WRN CANADA. NUMERICAL MODELS WERE SHOWING THE
LOW LIFTING INTO THE NW KANSAS BORDER SATURDAY WITH ASSOCIATED
MOISTURE ROTATING WESTWARD INTO THE WYOMING BORDER REGIONS WHILE THE
SYSTEM TO OUR NORTH CONTINUED TO SHEAR EAST THROUGH CANADA WHICH WAS
A SIGNIFICANT DEVIATION FROM PREVIOUS RUNS. THUS HAVE MAINTAINED A
SLIGHT CHANCE MENTION OF SHOWERS ALONG THE WYOMING BORDER SATURDAY.
A BROAD TROUGH DEVELOPS ACROSS THE MID-WEST WHILE A RIDGE REMAINS
POSITIONED ALONG THE COAST SUNDAY/MONDAY. UNDER THE DIRTY NW
FLOW...THE GFS WAS SHOWING A WEAK THREAT OF SHOWER ACTIVITY ALONG
THE WYOMING BORDER WHEREAS THE NAM WAS PRIMARILY DRY. THE GFS IS
TYPICALLY TOO GENEROUS WITH PRECIPITATION UNDER THESE FLOW REGIMES
AND THUS HAVE MAINTAINED A SLIGHT CHANCE MENTION OF PRECIPITATION
ALONG THE BORDER. AFTER COOLING SUNDAY...TEMPERATURES REMAIN
SEASONABLE THROUGH MONDAY. HUSTON

.LONG TERM...TUESDAY THROUGH SATURDAY. WARM TEMPERATURES AND HIGH
PRESSURE ON TUESDAY WILL GIVE WAY TO A DEVELOPING STORM SYSTEM WHICH
WILL IMPACT A LARGE PORTION OF THE WESTERN US THROUGH THE REST OF
THE WEEK.  FIRST OPPORTUNITY FOR SHOWERS AND ISOLATED THUNDERSTORMS
EXPECTED ON WEDNESDAY WITH INCREASING CONFIDENCE THROUGH FRIDAY FOR
WIDESPREAD SHOWERS AND ISOLATED THUNDERSTORMS.  LOWERING FREEZING
LEVELS WILL ALLOW MID AND HIGHER MOUNTAIN SNOW ACCUMULATION THURSDAY
AND FRIDAY.  OVERALL FIRST PART OF THE WEEK NICE..THE SECOND HAVE
STORMY.  TOO EARLY TO ANTICIPATED HOW MUCH LIQUID MOISTURE TO EXPECT
BUT SINCE THIS STORM HAS TIME TO DRAW IN PACIFIC OCEAN AIR EXPECT
HIGHER POTENTIAL FOR TOTAL PRECIPITATION AMOUNTS OVER ONE HALF TO
ONE INCH THROUGH THE ENTIRE LENGTH OF THE STORM.  FINAL IMPACT FROM
THE DEPARTING STORM ON SATURDAY AND PROBABLY MORE LIKELY INTO SUNDAY
IS POSSIBILITY FOR FREEZING TEMPERATURES PUTTING A DAMPER ON SPRING

TROUGH OR FRONTAL PASSAGE. 10 MB NORTHWEST-SOUTHEAST PRESSURE
GRADIENT ACROSS THE REGION ON SATURDAY FAVORS BREEZY CONDITIONS

.SHORT TERM...TODAY THROUGH SUNDAY NIGHT. UPPER LEVEL LOW IN
SOUTHERN ROCKIES VAST ENOUGH TO PERHAPS BRING SOME INSTABILITY AND
SHOWER ACTIVITY ON SAT AFTERNOON...BUT OTHERWISE TOO DRY TO DO
MUCH ELSE DURING THIS PERIOD AS THE LOW SLOWLY SLIDES EASTWARD AND
HIGH PRESSURE AT THE WEST COAST KEEPS THE FORECAST AREA IN DRY
NORTH-NORTHWESTERLY FLOW. EXPECT NEARLY CLEAR SKIES WITH THE
EXCEPTION OF SAT/SAT NIGHT. THIS WILL MEAN LARGE TEMPERATURE
SWINGS WITH TEMPERATURES GETTING ABOVE NORMAL FOR HIGHS AND NEAR
NORMAL FOR LOWS EXCEPT SUN NIGHT...WHEN THE NORTHERLY FLOW WILL
BRING IN COLDER THAN NORMAL LOWS...MANY BELOW FREEZING. NOT MUCH
EXPECTED IN THE WAY OF WIND UNDER HIGH PRESSURE.  MESSICK

.LONG TERM...MONDAY THROUGH FRIDAY. A RIDGE OF HIGH PRESSURE WILL
PRODUCE DRY WEATHER ACROSS THE REGION ON MONDAY. A LARGE BUT SLOW
MOVING LOW PRESSURE SYSTEM WILL APPROACH THE WEST COAST ON TUESDAY.
MODELS SHOW SOME MOISTURE WORKING INTO THE REGION TUESDAY
AFTERNOON...PERHAPS PRODUCING A FEW ISOLATED SHOWERS. THE LOW WILL
MOVE ONSHORE ON WEDNESDAY AND PUMP MORE MOISTURE INTO THE REGION
RESULTING IN BETTER CHANCES FOR ISOLATED TO SCATTERED SHOWERS.
MODELS SHOW SOME INSTABILITY SO A FEW RUMBLES OF THUNDER ARE
POSSIBLE AS WELL. BEST CHANCES FOR SHOWERS ARE THURSDAY AND FRIDAY
AS THE LOW MOVES FURTHER INTO THE GREAT BASIN AND A COLD FRONT
APPROACHES THE REGION. MODELS SHOW THIS FRONT MOVING THROUGH THE
REGION ON THURSDAY WHICH WILL BRING COOLER TEMPS AND CONTINUED
