.SHORT TERM...(THIS EVENING THROUGH WEDNESDAY)
ISSUED AT 223 PM MDT TUE APR 7 2015

SATELLITE AND OBS SHOWING RETREAT OF STRATUS TO THE FAR NE CORNER
WITH CLEARING ELSEWHERE. TEMPERATURES WILL BEGIN A GRADUAL REBOUND
INTO THE LOWER 60S BUT DROPPED HIGH TEMPS ACROSS THE PLAINS A FEW
DEGREES DUE TO THE SLOW START. SKIES WILL CLEAR OVERNIGHT BRINGING
TEMPERATURES DOWN INCREASING SATURATION THAT WILL ALLOW FOR
ANOTHER ROUND OF LOW STRATUS AND FOG WITH HELP FROM MOIST SE FLOW.
THERE IS SOME QG LIFT OVERNIGHT THAT COULD AID IN LIGHT DRIZZLE
OVER THE FAR NE CORNER INTO EARLY WEDNESDAY.

FOR WEDNESDAY A LEE SIDE SURFACE TROUGH WILL ALLOW FOR THE
CONTINUED DRIER SW FLOW THAT WILL DOWNSLOPE OFF THE PALMER KEEPING
THE SOUTHERN COUNTIES WARMER THEN FURTHER NORTH AS SEEN IN
PREVIOUS DAYS. THE SW WINDS WILL INCREASE ACROSS THE MOUNTAINS AND
SOUTHERN PLAINS THROUGH THE DAY WITH HELP FROM AN APPROACHING
UPPER TROUGH UPSTREAM AND A JET OVERHEAD. SHOWERS WILL INCREASE
OVER THE MOUNTAINS DURING THE AFTERNOON THEN MOVE OVER THE PLAINS
INTO THE EVENING HOURS. THERE IS SOME INSTABILITY OVER THE NE
CORNER WITH DECENT DEWPOINTS AND UPPER LEVEL QG SUPPORT SO HAVE
INCLUDED A SLIGHT CHANCE OF THUNDERSTORMS FOR THAT AREA WITH
RAINSHOWERS ELSEWHERE.

.LONG TERM...(WEDNESDAY NIGHT THROUGH TUESDAY)
ISSUED AT 225 PM MDT TUE APR 7 2015

THE MODELS ARE ALL PRETTY CONSISTENT REGARDING THE TROUGH CROSSING
THE CWA WEDNESDAY NIGHT. MODEST QG ASCENT IS EXPECTED THROUGH
AROUND 06Z WITH STRONG SUBSIDENCE OVERSPREADING THE AREA BEHIND
THE TROUGH THEREAFTER. CONSEQUENTLY BEST POPS WILL BE IN THE
EVENING WEDNESDAY...DECREASING OVERNIGHT AND INTO THURSDAY
MORNING. NORTHWEST FLOW IMPINGING ON THE HIGH COUNTRY WILL KEEP
THE THREAT OF OROGRAPHIC PRECIPITATION GOING UP THERE THROUGH
THURSDAY BUT COVERAGE SHOULD BE ON THE DECREASE THROUGHOUT THE DAY.
MINIMAL UPSLOPE IS PREDICTED EAST OF THE MOUNTAINS...WHICH COMBINES
WITH THE SUBSIDENCE TO LOWER PRECIPITATION CHANCES THERE. WINDS
WILL BE RATHER STRONG WITH AND BEHIND THE TROUGH SO A BLUSTERY AND
COOL DAY IS IN STORE FOR THURSDAY.

AFTER THE TROUGH GOES BY A RATHER BENIGN PATTERN SETS UP OVER THE
CENTRAL ROCKIES BRINGING GENERALLY DRY AND SEASONAL TO ABOVE
NORMAL TEMPERATURES TO THE AREA THROUGH AT LEAST SATURDAY.

THERE ARE SOME HINTS OF A WEAK SYSTEM COMING OUR WAY SATURDAY
NIGHT AND SUNDAY BUT IT DOES NOT LOOK TERRIBLY THREATENING AT
THIS POINT.
