TAIL END OF IDAHO/WESTERN MONTANA SHORTWAVE RIDING IN ON 60KT H2 JET
THIS AFTERNOON PROVIDING SOME LIFT ACROSS NWRN CORNER OF THE STATE.
LOW LEVEL MOISTURE STILL IN PLACE ACROSS MOST OF OUR NORTHCENTRAL AND
NORTHEAST ZONES WHERE POTENTIAL FOR ISOLATED STRONG STORMS WILL
PERSIST THIS EVENING. WIND RIVER BASIN ON SOUTHERN EDGE OF SHORTWAVE
AND WITH MOISTURE GRADUALLY ERODING...WE WILL BE HARD PRESSED TO SEE
MUCH ACTION THIS EVENING OUTSIDE OF SOME WIND.  ISOLATED STORMS
SHOULD STILL ROLL ACROSS FREMONT COUNTY THOUGH WITH A LITTLE MORE
ACTION POSSIBLE IN THE WIND RIVERS...ESPECIALLY NORTHERN PORTION.
PACNW TROUGH THEN APPROACHES MONDAY WITH DEVELOPING SURFACE LOW OVER
SOUTHERN MONTANA. WINDS SHOULD INCREASE IN MOST AREAS TOMORROW
AFTERNOON AND CONTINUE INTO THE EVENING. COLD FRONT SHOULD SWEEP
ACROSS THE NORTHERN ZONES TOMORROW EVENING AND INTO CENTRAL WYOMING
OVERNIGHT...SHIFTING WINDS TO THE NORTH OR NORTHEAST. A FIRE WEATHER
WATCH IS POSTED FOR ALL OFF SOUTHWEST AND WEST CENTRAL WYOMING
TOMORROW AFTERNOON AND EVENING AS MUCH DRIER AND BREEZY TO LOCALLY
WINDY CONDITIONS DEVELOP. DRIER MORE STABLE ARE BEHIND THE COLD FRONT
WILL GENERALLY CAP CONVECTION ON TUESDAY. ON WEDNESDAY...SOME
MOISTURE MAY TRY AND POOL EAST OF THE DIVIDE BUT IT STILL APPEARS
CONVECTION WILL BE LIMITED...IF IT OCCURS AT ALL. ISOLATED
THUNDERSTORMS IS ALL IM COMFORTABLE WITH FOR WEDNESDAY AFTERNOON.

UPPER RIDGE CONTINUES BUILDING OVER NEVADA DURING THE WEEK AND SEE
LITTLE CHANCE OF THUNDERSTORMS THURSDAY OR FRIDAY. ONLY EXCEPTION MAY
BE ACROSS THE FAR NORTH AS PASSING SOUTHERN CANADA SHORTWAVE PUSHES
ANOTHER COLD FRONT SOUTHWARD LATE IN THE DAY. THIS COULD SET THE
STAGE FOR MORE SIGNIFICANT CONVECTION IN DEVELOPING MOIST NORTHWEST
FLOW ALOFT NEXT WEEKEND. SURFACE HIGH PUSHES INTO MONTANA WITH
MOIST SOUTHEAST SURFACE FLOW AND GOOD DIRECTIONAL SHEAR FOR
POTENTIAL HAIL PRODUCING STORMS. ITS STILL A LONG WAY OFF BUT WORTH
KEEPING CHANCE POPS FOR DAYS 6 AND 7.

.RIW...NONE.
