910 PM MDT THU JUN 26 2008

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

ENERGY EXTENDING INTO THE AREA ASSOCIATED WITH A STRONG WAVE
MOVING INTO CENTRAL SASKATCHEWAN IS TRIGGERING ISOLATED CONVECTION
MAINLY OVER THE MOUNTAINS. A FEW AREAS OF OF CONVECTION ARE TRYING
TO FORM OVER THE PLAINS BUT AIRMASS DRIED OUT THIS AFTERNOON
BEHIND A WEAK FRONT AND MOST CONVECTION IS NOT MAKING IT DUE TO
ENTRAINMENT. HAVE DRIED OUT THE WESTERN ZONES THIS EVENING AND
HAVE KEPT THUNDERSTORMS FOR THE EASTERN ZONES BUT DO NOT EXPECT
SEVERE WEATHER. RAISED OVERNIGHT LOW TEMPERATURES A FEW DEGREES AS
SOME CLOUD COVER SHOULD KEEP MINIMUMS FROM FALLING MUCH UNTIL
AFTER MIDNIGHT. NORTHWEST FLOW ALOFT SHOULD ALLOW A CLEANER
AIRMASS TO BE OVER THE AREA TOMORROW SO WITH LESS CALIFORNIA SMOKE
OVER THE REGION COULD SEE TEMPERATURES WARM A BIT HIGHER THAN
FORECAST BUT WILL NOT UPDATE AT THIS TIME. BORSUM

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

EXTENDED FORECAST IN GOOD SHAPE RESULTING IN ONLY A FEW TWEAKS
WITH THIS ISSUANCE. STRONG RIDGE STILL EXPECTED TO MOVE OVER THE
NORTHERN ROCKIES THIS WEEKEND AND CONTINUE INTO NEXT WEEK. RIDGE
WILL BE MORE CENTERED OVER THE CENTRAL PORTIONS OF THE STATE
SUNDAY RESULTING IN SUBSIDENCE AND DRY CONDITIONS. HOWEVER...BY
MONDAY AND ESPECIALLY TUESDAY...THE RIDGE AXIS SHIFTS A BIT
WESTWARD. THIS WILL ALLOW FOR A FEW DISTURBANCES ALONG THE
PERIPHERY OF THE RIDGE TO MOVE ACROSS THE FORECAST AREA. WILL
CONTINUE WITH A SLIGHT THUNDERSTORM CHANCE MONDAY AFTERNOON
THROUGH THURSDAY WITH A SLIGHTLY BETTER CHANCE TUESDAY NIGHT AND
WEDNESDAY NIGHT AS POSSIBLY A STRONGER WAVE MOVES ACROSS THE
FORECAST AREA.

TEMPERATURES WILL BE HOT THROUGH THE PERIOD WITH READINGS IN THE
UPPER 80S TO LOWER 90S EACH DAY. AS THE PREVIOUS DISCUSSION
MENTIONED...WARMUP TO HOT TEMPERATURES MAY BE A BIT DELAYED DUE
TO AN EASTERLY SURFACE WIND...AS WELL AS INCREASED
MOISTURE/CLOUDS AND POSSIBLE THUNDERSTORM ACTIVITY. HOOLEY
