.SHORT TERM...VALID FOR WED AND THU...

ACTIVE NIGHT TONIGHT AS COLD FRONT PUSHES ACROSS AND UPPER LOW
BEGINS TO MOVE OVER AREA.

TONIGHT...CONVECTION ALREADY FIRING OVER WESTERN MONTANA AS 50
KNOT SOUTHWEST WINDS AT MID LEVELS PUSHES INTO WESTERN ZONES.
PROFILES HERE WILL SUPPORT PULSING STORMS...SOME HAIL AND WIND...SO WILL
CONTINUE THIS IN THE ZONES. IN EASTERN ZONES...PROFILE A BIT MORE
SUPPORTIVE FOR POSSIBLE ORGANIZED CONVECTION AS TROUGH PUSHES INTO
DAKOTAS. WILL PROBABLY BE A SHORT WINDOW OF OPPORTUNITY FOR SEVERE
THERE TROUGH PUSHES EAST. LATER TONIGHT...AFTER MIDNIGHT...UPPER
TROUGH AND A STRONG WAVE ROTATING AROUND IT PUSHES INTO WESTERN
THEN INTO BILLINGS AREA LATE TONIGHT. WAVE VERY STRONG AND SHOULD
FIRE AREA OF SHOWERS AND THUNDERSTORMS ACROSS WESTERN HALF OF
COUNTY WARNING AREA OVERNIGHT. HAVE RAISED POPS TO LIKELY AND
HIGHER FROM BILLINGS AND WEST FOR THIS. THE STRONG COLD FRONT
SHOULD PUSH INTO EASTERN ZONES BY 12Z AND WILL BE ACCOMPANIED BY A
FEW HOURS OF GUSTY WINDS.

WEDNESDAY...UPPER TROUGH MOVES ACROSS SOUTHERN CANADA WITH COLD
POOL ALOFT. MID LEVEL JET MAX PUSHES INTO EASTERN MONTANA AS FRONT
MOVES INTO DAKOTAS. EASTERN ZONES AND FAR SOUTH MAY HAVE A RISK OF
SEVERE WITH A HIGH SHEAR LOW CAPE SITUATION SETTING UP. WILL LEAVE
ANY MENTION OF THIS OUT FOR NOW AND LET MIDNIGHT SHIFT FINE TUNE.
HAVE KEPT A BROADBRUSH OF MID SCATTERED POPS GOING FOR THIS.

WEDNESDAY NIGHT...PATTERN BEGINS TO DRY OUT. ANOTHER SHOT OF COLD
AIR PROGGED BY BOTH NAM/GFS TO PUSH ACROSS EASTERN ZONES FOR SOME
WINDY/BREEZY CONDITIONS...BUT OVERALL DRYING.

THURSDAY...UNSEASONABLY COOL BUT DRY DAY AS UPPER LOW TRACKS
SLOWLY OFF TO THE EAST. HAVE RAISED WINDS TO WINDY WITH FAIR
LINKAGE WITH THE NORTHWEST FLOW ALOFT. RASCH

.LONG TERM...VALID FOR FRI...SAT...SUN...MON...TUE...

THE MEDIUM RANGE MODELS CONTINUE TO BE IN FAIRLY GOOD AGREEMENT
IN THE EXTENDED PERIODS. THE RECENT RUNS OF THE GFS80 ARE SHOWING
SOME INCONSISTENCY IN THE EXACT POSITION OF THE UPPER RIDGE...BUT
THE GENERAL IDEA EXPRESSED BY THE MODELS IS FOR A TROUGH ALONG
THE PACIFIC COAST...THEN A RIDGE OVER MONTANA...AND THE STRONGER
EXITING SYSTEM OVER LAKE WINNIPEG. THE EXTENDED FORECAST IS IN
GOOD SHAPE...AND HAVE MADE VERY FEW AND MINOR CHANGES FOR
COORDINATION TODAY. THE NEXT SYSTEM WHICH WILL PRODUCE ANY
CHANCES FOR PRECIPITATION ACROSS THE FORECAST AREA STILL LOOKS ON
TRACK FOR MOVING ACROSS THE AREA MONDAY AFTERNOON AND EVENING.
TEMPERATURES FOR MONDAY WILL REMAIN A SIGNIFICANT CHALLENGE UNTIL
BETTER TIMING CAN BE DETERMINED FOR THE FRONTAL PASSAGE. AT THIS
TIME...THE SLOWER GFS SOLUTION WOULD LIKELY PRODUCES HIGHS IN THE
LOWER 90S...WHILE THE FASTER EUROPEAN WOULD PRODUCE HIGHS IN THE
MID 70S. THE CURRENT FORECAST REMAINS A GOOD COMPROMISE WITH THIS
FORECAST PACKAGE. MODELS AGREE BETTER ON TEMPERATURES IN THE 70S
FOR TUESDAY BEHIND THE FRONT. WILL ALSO LEAVE THE CHANCES FOR
PRECIPITATION ALONE AS THE SYSTEM MOVES IN STARTING MONDAY.
