AREA FORECAST DISCUSSION...UPDATE
NATIONAL WEATHER SERVICE RIVERTON WY
1141 AM MDT SAT JUN 28 2014

.SHORT TERM...TODAY THROUGH MONDAY NIGHT

WARMER AND WINDY TODAY WITH CLEARING SKIES ACROSS MOST OF THE
FORECAST AREA...WITH SOME SHOWERS AND THUNDERSTORMS POSSIBLE ACROSS
THE NORTH WHERE A SHORT WAVE MOVING ACROSS MONTANA COULD CLIP THE
NORTHERN MOUNTAINS...THE BIGHORN BASIN AND JOHNSON COUNTY.
ELSEWHERE...RISING HEIGHTS AND SWIFT WESTERLIES WILL DRAW IN DRIER
AND WARMER AIR FROM THE GREAT BASIN. STEADY 15 TO 25 MPH WINDS WILL
BE COMMON ACROSS THE FORECAST AREA WITH 20 TO 30 MPH WINDS EXPECTED
ACROSS THE I80 CORRIDOR. THIS TREND CONTINUES FOR SUNDAY WITH
SLIGHTLY WARMER TEMPERATURES AND RISING HEIGHTS ACROSS THE FORECAST
AREA...COULD BE ENOUGH TO STRIP SHOWERS OUT OF THE FORECAST ACROSS
THE NORTH AS WELL.

MONDAY IS A LITTLE LESS CERTAIN...IT DEFINITELY LOOKS COOLER AGAIN
AS ANOTHER WAVE DROPS SOUTH OUT OF CANADA BUT THE AMOUNT OF MOISTURE
THAT COMES WITH IT IS IN QUESTION...IT LOOKS TO BE ON THE DRY SIDE
AT THIS TIME WITH COOL UPSLOPE FLOW BEHIND A COLD FRONT POTENTIALLY
SQUEEZING OUT SOME SHOWERS LATE MONDAY.

.LONG TERM...TUESDAY THROUGH SATURDAY

COOL...MOIST AND SLIGHTLY UNSTABLE NW FLOW REMAINS ACROSS EASTERN
WYOMING ON TUESDAY WHILE UPPER RIDGE OVER INTERMOUNTAIN WEST BUILDS
INTO WESTERN WYOMING.  SLIGHT CHANCES OF THUNDERSTORMS INTRODUCED
OFF THE EAST SLOPES OF THE BIG HORNS AND DOWNWIND ALONG WITH COOLING
HIGH TEMPERATURES A FEW DEGREES.  TUESDAY LOOKS LIKE THE LAST DAY WE
WILL SEE HIGHS IN THE 70S FOR AWHILE AS SUMMERTIME UPPER RIDGE
EXPANDS OVER THE ROCKIES AND SOUTHERN/CENTRAL PLAINS WEDNESDAY
THROUGH INDEPENDENCE DAY.  ECMWF OPERATIONAL SHOWS UPPER LOW ALONG
THE BRITISH COLUMBIAN COAST SHEARING INTO ALBERTA/SASKATCHEWAN BY
INDEPENDENCE DAY WHILE THE GFS KEEPS THE UPPER LOW OFF THE COAST
WITH SHORTWAVES EJECTION NORTH OVER STRONGER DOWNSTREAM RIDGE.  GFS
AND ECMWF ENSEMBLE MEANS A BETTER MATCH WITH THE GFS.

THUS...FEW CHANGES TO GOING FORECAST WITH WARMING TREND WEDNESDAY
AND THURSDAY WITH CENTRAL BASIN HIGHS MOSTLY IN THE 90-95F RANGE
THURSDAY AND INDEPENDENCE DAY.  LEE SIDE TROUGH/DRYLINE MEAN
POSITION WILL BE N-S NEAR INTERSTATE 25...THEN EXTENDING WESTWARD
INTO THE BIG HORN BASIN.  THE BETTER MOISTURE AND INSTABILITY WILL
BE TO THE NORTH AND EAST OF THIS BOUNDARY WHERE ISOLATED
THUNDERSTORMS WILL BE CAPABLE OF PRODUCING HEAVY DOWNPOURS AND HAIL.
ANY THUNDERSTORMS THAT FORM TO THE SOUTH AND WEST IN THE DRIER AIR
WILL BE PRIMARILY HIGH-BASED...LESS RAIN/MORE WIND.

NO MAJOR CHANGES TO THIS OVERALL MORE SUMMER-LIKE PATTERN EXPECTED
OVER THE FOURTH OF JULY WEEKEND.
