AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE RIVERTON WY
1153 AM MDT FRI JUN 5 2015

.PREV DISCUSSION... /ISSUED 305 AM MDT FRI JUN 5 2015/

.SHORT TERM...FRIDAY THROUGH SUNDAY NIGHT

AN INTERESTING EVENING AT THE HUMBLE RIVERTON WEATHER ABODE LAST
NIGHT AS A LOW LEVEL JET MOVED IN AND SPAWNED SOME NASTY
THUNDERSTORMS THAT DROPPED PING PONG BALL SIZE HAIL ACROSS PORTIONS
OF FREMONT AND HOT SPRINGS COUNTY. CONVECTION IS STILL ONGOING BUT
HAS WEAKENED AS IT MOVES NORTHEAST INTO THE BIG HORN BASIN. AS FOR
TODAY...CONTINUITY LOOKED REASONABLE SO WE MADE ONLY A FEW CHANGES
TO TIMING TO PUSH OFF THE START OF THE CONVECTION A FEW HOURS THIS
AFTERNOON. THE LATEST CONVECTIVE OUTLOOK HAS NOT CHANGED MUCH WITH
MUCH OF THE AREA EAST OF THE DIVIDE IN THE MARGINAL AREA AND AREAS
EAST OF THE BIG HORN RANGE IN THE SLIGHT RISK. WE CONTINUE TO HAVE
THE FRONT ACROSS THE AREA AS A FOCUSING MECHANISM. MODELS ARE
SHOWING OVER 2000 J/KG OF CAPE ACROSS NORTHERN AREAS OF THE AREA
WITH LIFTED INDICES FALLING AS LOW AS MINUS 9. IN ADDITION...THERE
WILL BE SOME JET ENERGY AS A JET STREAK MOVES IN FROM THE NORTH AND A
SHORTWAVE APPROACHING FROM THE SOUTHWEST. AS A RESULT...WE LEFT THE
SEVERE WORDING IN THE FORECAST FOR AREAS EAST OF THE DIVIDE. THE
BEST CHANCE OF STRONGER STORMS MAY BE ACROSS NORTHERN WYOMING...BUT
EVERYONE EAST OF THE DIVIDE WILL HAVE A CHANCE. CONVECTION SHOULD
SUBSIDE LATER TONIGHT BUT NOT END. THE OTHER THREAT IS FOR FLOODING
WITH SATURATED SOILS IN MANY LOCATIONS. AS A RESULT...WE WILL
CONTINUE THE FLASH FLOOD WATCH AS IS.

AS FOR SATURDAY...THE RISK FOR SEVERE WEATHER SHOULD DECREASE A BIT
AS INCREASED CLOUD COVER AND LOWER TEMPERATURES SHOULD DROP
INSTABILITY A BIT. HOWEVER...THE ATMOSPHERE WILL REMAIN RATHER MOIST
AS EASTERLY FLOW CONTINUES ACROSS THE AREA. PRECIPITABLE WATER
VALUES ACTUALLY CLIMB A BIT WITH VALUES APPROACHING AN INCH ACROSS
MANY OF THE LOWER ELEVATIONS EAST OF THE DIVIDE. SO THE MAIN THREAT
MAY SHIFT TO HEAVY RAIN FOR THIS DAY.

SUNDAY ALSO LOOKS LIKE A RATHER UNSETTLED DAY WITH MORE CLOUDS AND
SHOWERS. FLOW LOOKS TO TURN MORE NORTH TO NORTHEAST WHICH WILL COOL
TEMPERATURES A FEW MORE DEGREES. THIS WILL ALSO STABILIZE THE
ATMOSPHERE A BIT MORE SO THE RISK OF SEVERE WEATHER SHOULD CONTINUE
TO DROP AS WELL. THE MODELS ARE ALSO SHOWING SOME DRIER AIR TRYING
TO PUNCH INTO NORTHERN WYOMING SO THERE IS A CHANCE THERE COULD BE A
HALFWAY DECENT DAY UP THERE. NEVERTHELESS...IT SHOULD BE A BIT DRIER
THAN SATURDAY.

.LONG TERM...MONDAY THROUGH FRIDAY

THE GFS MODEL HAS UNSETTLED WEATHER LINGERING ON MONDAY WHILE THE
ECMWF IS MUCH DRIER. WILL KEEP A LOW CHANCE OF SHOWERS AND STORMS
ON MONDAY INTO MONDAY NIGHT. ON TUESDAY AFTERNOON AND NIGHT ISOLATED
SHOWERS AND STORMS LOOK TO OCCUR OVER THE NORTH AND MOST MOUNTAINS.
A WEAK WEATHER SYSTEM MOVES THROUGH ON WEDNESDAY. THIS WILL HELP
GENERATE MORE SHOWERS AND THUNDERSTORMS ACROSS THE AREA WEDNESDAY
AFTERNOON AND NIGHT. THURSDAY AND FRIDAY ALSO LOOK UNSETTLED WITH
SHOWERS AND ISOLATED THUNDERSTORMS OVER MUCH OF THE REGION. HIGH
TEMPS WILL BE SEASONABLY WARM MONDAY THROUGH WEDNESDAY...THEN
SLIGHTLY COOLER THURS AND FRI AS MORE CLOUDS WILL WE PRESENT.

.AVIATION.../18Z ISSUANCE/

SHOWER AND THUNDERSTORM COVERAGE WILL STEADILY INCREASE THIS
AFTERNOON...WITH MANY TERMINALS SEEING THE POTENTIAL FOR SHOWER
ACTIVITY BY 20Z TODAY. SOME THUNDERSTORMS MAY BE
STRONG...PRODUCING PERIODS OF HEAVY RAINFALL...STRONG WIND...AND
LARGE HAIL. THE HEAVY RAIN AND POTENTIAL FOR HAIL MAY RESULT IN
PERIODS OF MVFR TO IFR CONDITION AT AREA TERMINALS...ESPECIALLY
AFTER 21Z THIS AFTERNOON. SHOWERS AND THUNDERSTORMS WILL REMAIN
PRESENT THROUGH AT LEAST 04Z- 07Z SATURDAY. ACTIVITY WILL THEN
START TO WEAKEN...WITH THUNDERSTORM COVERAGE DIMINISHING THROUGH
THE REMAINDER OF THE FORECAST PERIOD.

.FIRE WEATHER...

FIRE DANGER SHOULD REMAIN LOW THROUGH THE WEEKEND. A FRONTAL
BOUNDARY WILL REMAIN ACROSS WYOMING AND DISTURBANCES MOVING THROUGH
THE AREA WILL KEEP THE CHANCE OF SHOWERS AND THUNDERSTORMS IN THE
FORECAST THROUGH SUNDAY WITH THE BEST CHANCES ON FRIDAY AND
SATURDAY. OTHER THAN FIRE STARTS THROUGH LIGHTNING STRIKES...AND
ERRATIC BEHAVIOR WITH GUSTY WINDS..FIRE BEHAVIOR SHOULD BE
RELATIVELY TAME.
