.SHORT TERM...VALID FOR FRI AND SAT...

THUNDERSTORMS FIRING OVER SOUTHERN AND EASTERN COUNTIES WHERE
HIGHER DEWPOINTS AND DEEPER BOUNDARY LEVEL MOISTURE LOCATED TODAY
TO THE EAST OF AN INVERTED SURFACE TROUGH. NO SIGNIFICANT
TRIGGERS APPARENT AT THIS TIME...BUT A WEAK IMPULSE NOTED ON
SATELLITE IMAGERY IS POPPING SOME WEAKER CONVECTIONS OVER
SOUTHWEST MOUNTAINS. WHILE THE CONVECTION IN WEST SHOULD STAY
RELATIVELY HIGH BASED...THIS FEATURE WILL WORK WITH DEEPER
MOISTURE OVER SOUTHERN AND EASTERN SECTIONS LATER TODAY TO PRODUCE
SOME STRONG THUNDERSTORMS. NAM DOES DEPICT A 300MB DIVERGENCE
TRACKING OVER OUR AREA ABOUT SAME TIME. WATCH ISSUED UNTIL 04Z FOR
THE SOUTHEAST INTO SHERIDAN COUNTY. HAVE ADJUSTED POPS ACCORDINGLY
AND WILL LINGER SLIGHT CHANCE INTO SOUTHEAST LATE.

RIDGE OF HIGH PRESSURE WILL BE BUILDING OVER REGION FRIDAY AND
INTO WEEKEND. THIS WILL PREVENT ANY SIGNIFICANT TRIGGERS ALOFT
FROM AFFECTING OUR FORECAST AREA. LOW LEVEL MOISTURE LOOKS
MARGINAL TO SUPPLY MUCH CONVECTION WITH SOUNDINGS INDICATING WEAK
CAPE IN WEST AND POSSIBLY CAPPED ENVIRONMENT IN EAST. DIFFERENTIAL
HEATING WILL PRODUCE SOME SHOWERS OVER HIGHER TERRAIN WEST LATE
EACH DAY. CONVECTION IN EAST A BIT MORE QUESTIONABLE...BUT ANY
THAT DOES DEVELOP MAY BE STRONG DUE TO SHEAR AND ELEVATED CAPE
OVER 1000 J/KG. WILL OPT TO KEEP POPS BELOW SEASONAL NORMS.
TEMPERATURES WILL BE IN THE 80S EACH DAY WITH SATURDAY LOOKING THE
WARMEST. BT

.LONG TERM...VALID FOR SUN...MON...TUE...WED...THU...

MEDIUM RANGE GUIDANCE ALL IN GOOD AGREEMENT THROUGH THE EXTENDED
PERIOD WITH WARM TEMPERATURES AND ISOLATED TO SCATTERED
THUNDERSTORMS THROUGHOUT THE PERIOD.

UPPER RIDGE SLIDES ACROSS THE REGION ON SUNDAY WITH WEAK SHORTWAVE
BRINGING A MORE ORGANIZED THREAT OF THUNDERSTORMS ACROSS THE AREA
ON SUNDAY NIGHT AND INTO SOUTHEAST MONTANA MONDAY. UPPER FLOW
BECOMES MORE ZONAL TUESDAY THROUGH THE END OF NEXT WEEK.
HOWEVER...UPPER HEIGHTS DO BUILD ACROSS THE AREA WHICH SHOULD LEAD
TO WARMER TEMPERATURES FOR MID TO LATE NEXT WEEK AND LESS
ORGANIZED THUNDERSTORM THREAT. ONLY MINOR CHANGES MADE TO THE
EXTENDED PERIOD TO SUPPORT COLLABORATION WITH OTHER OFFICES. MEIER

&&

.AVIATION...

VFR CONDITIONS WILL PREVAIL ACROSS THE REGION THROUGH FRIDAY MORNING.
ISOLATED THUNDERSTORMS ARE EXPECTED THROUGH THIS EVENING FROM
LIVINGSTON TO BILLINGS...AND MAY BECOME MORE NUMEROUS EAST OF A
SHERIDAN TO MILES CITY LINE. LOCALIZED MVFR CONDITIONS WILL
ACCOMPANY ANY STORMS THAT DO DEVELOP. MEIER
