300 AM MDT MON JUN 19 2006

.SHORT TERM...TODAY THROUGH WEDNESDAY NIGHT
WIDESPREAD SCATTERED SHOWERS AND THUNDERSTORMS ARE PARADING
NORTHEAST ACROSS CENTRAL WYOMING AS A SERIES OF SMALL DISTURBANCES
IN THE INCREASING SOUTHWEST FLOW AHEAD OF THE STRONG APPROACHING
PACIFIC SHORTWAVE TROUGH HELP INCREASE NOCTURNAL DYNAMICS EARLY THIS
MORNING. THIS SHORTWAVE WILL BE EJECTED EAST BY A CLOSED LOW NOW
MAKING LAND-FALL ALONG THE SOUTHERN BRITISH COLUMBIA COAST. THE
SHORTWAVE WILL BE TRACKING EAST ACROSS WYOMING EARLY THIS EVENING.
VERY DRY AND WINDY CONDITIONS HAVE PROMPTED THE ISSUANCE OF A RED
FLAG WARNING FOR SOUTHERN AND CENTRAL WYOMING FOR THIS AFTERNOON.
NORTH OF THE OWL CREEK MOUNTAINS AND EAST OF THE CASPER ARCH
DYNAMICS WILL BE MORE FAVORABLE FOR WETTER STRONGER THUNDERSTORMS
FOR THIS AFTERNOON AND EVENING AS LIFTED INDICES OF -3...670 CAPES
AND PW AMOUNTS OF OVER ONE INCH HELP INITIATE STRONGER DEVELOPMENT.
STRONG QG FORCING IS PROGGED FOR MONTANA TODAY BRUSHING FAR
NORTHERN WY. THE NAM IS A LOT SLOWER WITH THE ASSOCIATED WEAK COLD
FRONT SO HAVE KEPT ISOLD POPS THROUGHOUT THE AREA UNTIL MIDNIGHT
TONIGHT TO ACCOUNT FOR THIS UNCERTAINTY. OTHERWISE ENDED THE POPS
RATHER ABRUPTLY FROM SOUTHWEST TO NORTHEAST THIS EVENING TO ACCOUNT
FOR THE STRONG SUBSIDENCE AND DRYING BEHIND THIS SHORTWAVE. STORMS
SHOULD TEND TO CONCENTRATE ALONG THE RESULTANT DRY LINE TODAY. SPC
HAS THE NORTHERN HALF OF OUR CWA IN A SLIGHT RISK TODAY. ONCE THE
SUBSIDENCE AND CONFLUENT FLOW ENSUE THE WEATHER WILL BECOME MORE
BENIGN. TUESDAY WILL ONLY FEATURE ISOLD POPS IN THE AFTERNOON IN THE
NORTHWEST AS THE CLOSED LOW ITSELF OPENS UP AND EJECTS EAST ACROSS
NORTHERN MT. AFTER HIGHS IN THE LOW 90S IN PORTIONS OF NATRONA COUNTY
TODAY...HIGHEST TEMPS WILL COOL TO THE MID TO UPPER 80S IN THE
WARMEST AREAS EAST OF THE DIVIDE BY TUESDAY. SHOULD SEE SOME RATHER
CHILLY LOW TEMPS REACHING FREEZING OR A LITTLE BELOW IN THE
WESTERN VALLEYS AND BASINS BEHIND THIS FRONT TUE AND WED NT WITH
FAIRLY GOOD RADIATIONAL COOLING.

.LONG TERM...THURSDAY THROUGH MONDAY
WEAK DISTURBANCE STILL EXPECTED TO MOVE ACROSS MONTANA ON THURSDAY
PUSHING A COLD FRONT SOUTH INTO NRN WYOMING. COMBINATION OF THIS
BOUNDARY WITH SOME MOISTURE AND WEAK INSTABILITY IS STILL WORTH
ISOLATED THUNDERSTORMS. ON FRIDAY...A RETURN FLOW OF MOISTURE MAY
SET UP ACROSS THE ERN ZONES LEADING TO LATE DAY CONVECTION ALONG THE
MOISTURE DISCONTINUITY...ESPECIALLY WITH POTENTIAL FOR WNW TO NW
FLOW AND FAVORABLE SHEAR PROFILE. SAME COULD HAPPEN ON SATURDAY BUT
AFTER COLLABORATION WILL LEAVE IT DRY FOR NOW. ON SUNDAY...MONSOONAL
MOISTURE COULD BEGIN EDGING AROUND THE DESERT SOUTHWEST HIGH. WILL
BROADBRUSH THE SOUTHWEST AREA WITH ISOLATED THUNDERSTORMS FOR SUNDAY
AND THE ENTIRE AREA ON MONDAY. HARD TO TELL YET HOW MUCH MOISTURE
WILL MOVE NORTH AROUND THIS UPPER HIGH SINCE ITS NOT POSITIONED
OPTIMALLY NEAR THE 4-CORNERS.
