AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DENVER/BOULDER CO
757 PM MDT FRI AUG 28 2015

.UPDATE...
ISSUED AT 757 PM MDT FRI AUG 28 2015

JUST A FEW WEAK SHOWERS AND STORMS REMAIN OVER THE AREA...MAINLY
OVER PARK COUNTY. OTHERWISE SKIES ARE MOSTLY CLEAR ACROSS THE
STATE. CURRENT FORECAST CARRIES POPS THROUGH 10 PM WHICH LOOKS
GOOD. ONLY CHANGES PLANNED WILL BE TO ADJUST TO CURRENT TRENDS.

&&

.SHORT TERM...(THIS EVENING THROUGH SATURDAY)
ISSUED AT 246 PM MDT FRI AUG 28 2015

SOME WEAK SHOWERS OCCURRING OVER THE MOUNTAINS...ONLY ONE WITH
LIGHTNING SO FAR. STILL EXPECTING SCATTERED COVERAGE OF WEAK
SHOWERS/STORMS OVER THE MOUNTAINS THROUGH THE EARLY
EVENING...WITH A VERY LOW CHANCE OF RAIN EVERYWHERE ELSE. STILL
SOME LOWER VISIBILITIES IN SMOKE UPSTREAM OVER
WYOMING...VISIBILITIES MOSTLY AROUND 8-10 MILES BUT SOME SPOTS AS
LOW AS 5. NOT QUITE AS BAD AS LAST SATURDAY...BUT IT WILL LIKELY
GET A BIT WORSE IN OUR AREA TONIGHT BEFORE HOPEFULLY IMPROVING
LATER ON SATURDAY AS THE LOW TO MID LEVEL WINDS TURN AROUND TO
THE SOUTHWEST.

I DROPPED TEMPERATURES TONIGHT SLIGHTLY MAINLY OVER THE MOUNTAINS
WITH CLEARING AND DRY AIR...EXPECT ONLY A SMALL EFFECT IF ANY FROM
THE SMOKE.

SATURDAY LOOKS LIKE A NEARLY DRY DAY AS THERE IS BOTH LOW LEVEL
DRYING AND WARMING ALOFT. STILL MIGHT BE ENOUGH MOISTURE FOR SOME
WEAK MOUNTAIN SHOWERS...BUT PROBABLY LESS THAN TODAY AND MAINLY
SOUTH OF OUR AREA. FORECAST HIGHS ARE A LITTLE WARMER THAN
TODAY...MATCH GUIDANCE AND LOOK GOOD.

.LONG TERM...(SATURDAY NIGHT THROUGH FRIDAY)
ISSUED AT 246 PM MDT FRI AUG 28 2015

MODELS HAVE THE UPPER RIDGE AXIS STRETCHED SOUTHWEST TO NORTHEAST
OVER THE CWA AND PARTS FURTHER SOUTH FOR ALL FIVE PERIODS. LIGHT

HAVE A TAD OVER MEASURABLE RAINFALL OVER THE SOUTHWESTERN CWA
SATURDAY EVENING. THERE IS MORE OVER THE MOUNTAINS AND FOOTHILLS
LATE DAY SUNDAY...SAME FOR MONDAY AND THERE IS EVEN MINOR AMOUNTS
OVER THE WESTERN 2/3RDS OF THE PLAINS. FOR POPS...A BIT IN THE
MOUNTAINS SATURDAY EVENING...THEN 20-50%S LATE DAY SUNDAY AND LATE
DAY MONDAY. THERE WILL BE 10-20% POPS FOR THE PLAINS SUNDAY
EVENING AND LATE DAY MONDAY. FOR TEMPERATURES...SUNDAY`S HIGHS
