AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RIVERTON WY
233 PM MDT THU SEP 12 2013
.SHORT TERM...TONIGHT AND FRIDAY
VERY SLOW MOVING UPPER LOW OVER WRN UTAH WILL ONLY DRIFT VERY SLOWLY
NWD OVER THE NEXT 24 HOURS WITH THE TROPICAL AIRMASS REMAINING OVER
THE AREA. THE ORGANIZED SHORTWAVE THAT PRODUCED SIGNIFICANT RAIN
OVER OUR CENTRAL ZONES LATE LAST NIGHT INTO THIS MORNING IS DRIFTING
NWD ATTM INTO THE ABSAROKA MOUNTAINS AND SRN BIGHORN BASIN. IN THE
SOUTHWEST...BUILDING CAPE WILL RESULT IN WIDELY SCATTERED TO
SCATTERED THUNDERSTORMS WITH THE POTENTIAL FOR HEAVY RAIN INTO THE
EVENING HOURS. A FEW STORMS COULD ALSO FORM IN CENTRAL WYOMING AND
SHEEPHERDER BURN SCAR ON CPR MOUNTAIN WILL HAVE TO BE WATCHED
CLOSELY INTO THE EVENING HOURS. ISENTROPIC UPGLIDE WILL CONTINUE
INTO THE EARLY EVENING BEFORE WANING AND BECOMING QUITE WEAK OR
NON-EXISTENT BY FRIDAY MORNING. THERE IS ALSO A POTENTIAL SHORTWAVE
FORMING OVER SWRN WYO THAT MAY FOCUS CONVECTION THROUGH THE EVENING
HOURS. ON FRIDAY...WE LOSE OUR UPSLOPE EAST OF THE DIVIDE AND
ISENTROPIC UPGLIDE BUT WE TRANSITION TO MORE INSTABILITY ACROSS THE
ENTIRE AREA WITH MORE HEATING POTENTIAL. THE MOUNTAINS WILL BE
SUSCEPTIBLE TO THUNDERSTORMS WITH HEAVY RAIN WITH A FEW HEAVY
RAINERS ACROSS THE LOWER ELEVATIONS TOO.
.LONG TERM...FRIDAY NIGHT THROUGH THURSDAY
...WET AND UNSETTLED THROUGH THE WEEKEND WITH SOME DRYING EXPECTED
ON MONDAY...
AN UPPER LOW CONTINUES TO LIFT NORTHEAST FRIDAY NIGHT INTO THE
DAKOTAS. THE LATEST MODEL RUNS STILL OPEN THE LOW UP AS A TROUGH
DIPS INTO SOUTHERN CANADA. THE MAIN DIFFERENCE THAT THE MODELS
ACTUALLY AGREE ON IS THAT THE LOW TIGHTENS UP AGAIN IN SOUTHEASTERN
MONTANA ON FRIDAY EVENING AS A SHORT WAVE AND ASSOCIATED VORT MAX
MOVE THROUGH. PRECIPITATION CHARACTER TURNS MORE CONVECTIVE ON
FRIDAY AS A MORE ORGANIZED WAVE MOVES THROUGH...ALONG WITH SOME WAA
AT THE SURFACE INCREASES INSTABILITY SOMEWHAT.
MODELS CONTINUE TO INDICATE A WEAK COLD FRONT PUSHING SOUTH ACROSS
THE FORECAST AREA SATURDAY. THE COMBINATION OF THIS UPPER LOW...COLD
FRONT...AND WEAK INSTABILITY WILL RESULT IN A DECENT CHANCE OF
MORE RAIN...ESPECIALLY EAST OF THE DIVIDE WHERE SOME LOW LEVEL
UPSLOPE FLOW WILL MAINTAIN A DECENT SUPPLY OF MOISTURE. ISOLATED TO
SCATTERED CONVECTION IS EXPECTED AGAIN SUNDAY WITH THIS WEAK
TROUGHINESS REMAINING OVER THE AREA...BUT COVERAGE IS EXPECTED TO BE
LESS THAN WHAT OCCURS SATURDAY/SATURDAY NIGHT.
GLOBAL MODELS SHOW AN UPPER LOW...OPENING UP AND SWINGING ACROSS
THE PACIFIC NORTHWEST SUNDAY/SUNDAY NIGHT IN RESPONSE TO A STRONG
UPPER LOW IN THE GULF OF ALASKA SLIDING SOUTHEAST. THIS LEAD TROUGH
WILL FINALLY KICK THE UPPER LOW AWAY FROM THE COWBOY STATE. THE MAIN
UPPER LOW/TROUGH IS EXPECTED TO BE NEAR THE PACIFIC NORTHWEST
COASTAL REGION MONDAY WHILE WARM AND DRY SOUTHWEST FLOW SETS UP OVER
THE INTERMOUNTAIN WEST. LATEST MODEL RUNS ARE ACTUALLY BEGINNING TO
AGREE FAIRLY WELL FOR THIS FAR OUT THAT THE LEAD TROUGH WILL
PROGRESS EASTWARD AND BEGIN TO AFFECT THE NORTHERN ROCKIES BY
TUESDAY EVENING. THE MAIN DIFFERENCE IS THAT THE GFS HOLDS BACK A
STRONGER CLOSED LOW OFF THE WASHINGTON COAST THROUGH WEDNESDAY NIGHT
AND THEN SETTING THE INTERMOUNTAIN WEST UP INTO MORE PROGRESSIVE
WESTERLY FLOW WHILE THE EUROPEAN PLACES A MORE AMPLIFIED RIDGE OVER
THE COWBOY STATE...WHICH WOULD BE DRIER AND WARMER THAN THE GFS
SOLUTION.
.AVIATION.../00Z ISSUANCE/
A VERY MOIST STORM SYSTEM WILL KEEP WIDESPREAD SHOWERS AND SOME
THUNDERSTORMS ACROSS MUCH OF THE AREA THROUGH FRIDAY. THE MOST
CONCENTRATED AREA WILL BE ONE BAND FROM THE WIND RIVER MOUNTAINS
TO THE ABSAROKA MOUNTAINS WHERE IFR CONDITIONS AND WIDESPREAD
MOUNTAIN OBSCURATIONS WILL CONTINUE INTO THIS EVENING. DEVELOPING
THUNDERSTORMS WILL PRODUCE WIDELY SCATTERED TO SCATTERED THUNDERSTORMS
TO AREAS ALONG AND WEST OF THE DIVIDE THIS AFTERNOON AND EVENING
WITH MVFR CONDITIONS TO LCL IFR AND MOUNTAIN OBSCURATION.
PARTIAL CLEARING BEHIND THIS BAND OF PRECIPITATION WILL LIKELY
RESULT IN AREAS OF IFR FOG DEVELOPING ACROSS SOUTHWEST AND CENTRAL
WYOMING TONIGHT...ESPECIALLY VCNTY KRKS-KLND.
.FIRE WEATHER...
THE WEATHER WILL CONTINUE UNSETTLED THROUGH THE WEEKEND. THE THREAT
OF HEAVY RAIN AND THUNDERSTORMS IN THE MOUNTAINS WILL CONTINUE
THROUGH FRIDAY WITH SCATTERED TO WIDESPREAD SHOWERS AND A FEW
THUNDERSTORMS ACROSS THE LOWER ELEVATIONS. THERE WILL BE A CONTINUED
CHANCE OF SHOWERS AND A FEW THUNDERSTORMS SATURDAY AND SUNDAY WITH
SOME WIDESPREAD UPSLOPE RAIN EAST OF THE DIVIDE LATE SATURDAY INTO
SATURDAY NIGHT. A SOMEWHAT DRIER AIRMASS WILL MOVE IN MONDAY INTO
TUESDAY BUT WITH INCREASING SOUTHWEST FLOW.

Flash Flood, Lincoln
- When
- September 12, 4:45 PM MST to 7:00 PM MST
- Where
- Lincoln County, 0.55 mi SE of La Barge to 5.15 mi W of La Barge
- Cause
- Heavy Rain
- Property damage
- $1.5 million
- Reported by
- Law Enforcement
- Coordinates
- 42.265, -110.192
Heavy rain from thunderstorms brought flooding and mudslides in, and to the south of, LaBarge. The flooding damaged 20 homes located mainly in the southwest portion of the town. Much of the flooding was confined to basements of homes and at least one church. High water scoured the channel of Birch Creek at the north end of town and exposed water and sewer pipes.
To the south of town, approximately four separate large channels along with many smaller rivulets flooded US Highway 189 between mileposts 77 and 81. The Wyoming Highway Patrol reported a mudslide near milepost 78 around Muddy Creek at 1651MST. Farther north near Names Hill another small canyon deposited mud and rock across the highway and onto private land. Five homes were damaged in the county, one of which was declared a total loss. Multiple sections of fence line were either washed away or completely buried by debris. Mud and rock plugged culverts along the highway and also buried culvert inlets. This set the stage for additional flooding across US Highway 189 over the course of the next several days.
- Flash Flood
- Flooding that begins within six hours of the rain that causes it, or of a dam or levee failure or ice jam release, often with deadly speed.
