359 AM MDT THU JUN 3 2010

.DISCUSSION...
THURSDAY THROUGH SATURDAY...A SHORTWAVE SYSTEM WITH ASSOCIATED
COLD FRONT WILL MOVE ACROSS THE AREA EARLY THIS MORNING CAUSING
WIDESPREAD SHOWERS AND A SLIGHT DROP IN TEMPERATURES FOR TODAY.
SHOWERS SHOULD DISSIPATE QUICKLY BEHIND THE FRONT AS IT PASSES OVER
THE REGION. WINDS WILL INCREASE BEHIND THE FRONT TODAY AND THROUGH
THE AFTERNOON. SOME LOCATIONS FAVORED FOR STRONG WINDS MAY HAVE
OBSERVATIONS THAT NEAR HIGH WIND WARNING CRITERIA...HOWEVER SHOULD
BE OUTLIERS AS THE CONDITIONS ACROSS THE AREA REMAIN BELOW HIGH
WIND WARNING CRITERIA. FRIDAY TEMPERATURES WILL CONTINUE TO REMAIN
A SLIGHTLY BELOW SEASONAL AVERAGES WITH WINDS AGAIN INCREASING
DURING DAYTIME HEATING. WINDS WILL NOT BE NEARLY AS STRONG.
HOWEVER WITH DECENT UPPER LEVEL SUPPORT FROM AN EXIT REGION OF A
JET STREAK...ALONG WITH DIURNAL HEATING AND THE CONTINUATION OF
THE MOIST FLOW...THERE WILL BE THE POSSIBILITY OF SOME ISOLATED
SEVERE THUNDERSTORMS. FRIDAY AFTERNOON AND EVENING ACROSS THE
AREA. SATURDAY CONDITIONS WILL BE SLIGHTLY CALMER AS WINDS
CONTINUE TO DIMINISH...HOWEVER AFTERNOON SHOWERS AND THUNDERSTORMS
REMAIN A POSSIBILITY DUE TO DAYTIME HEATING OF THE UNSTABLE MOIST
FLOW. SUK

SATURDAY NIGHT THROUGH THURSDAY...A STRONG WESTERLY JET WITH ZONAL
FLOW ALOFT WILL PREVAIL ACROSS THE NORTHERN ROCKY MOUNTAIN REGION

MOUNTAINS. THE NEXT SHORTWAVE TROUGH PUSHES INTO THE STATE SUNDAY
AFTERNOON WITH SCATTERED SHOWERS AND A FEW THUNDERSTORMS EXPECTED
OVER THE PLAINS SUNDAY NIGHT THROUGH MONDAY. MEDIUM RANGE MODEL
SOLUTIONS DIVERGE BY MID WEEK...BUT RECENT VERIFICATION STATS
SUGGEST THAT THE GFS SOLUTION SHOULD BE SUPERIOR DURING THIS TIME
FRAME SO HAVE TRENDED THE FORECAST IN THIS DIRECTION. GFS BEGINS TO
BUCKLE THE FLOW ALOFT ON TUESDAY WITH A DECENT RIDGE AXIS FORMING
OVER MONTANA BY THURSDAY. WITH THIS SOLUTION HAVE BUMPED UP
TEMPERATURES AND LOWERED THE CHANCE OF PRECIPITATION BELOW
CLIMATOLOGY. MPJ
