AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RIVERTON WY
241 PM MDT SUN JUL 21 2013

.SHORT TERM...TONIGHT THROUGH MONDAY

SATELLITE IMAGERY IS SHOWING A MAINLY CLEAR SKY ACROSS MOST OF THE
COUNTY WARNING AREA THROUGH NOON. THE EXCEPTION ARE SOME CUMULUS
CLOUDS OVER THE USUAL SPOTS LIKE THE BIG HORN RANGE AND PORTIONS OF
THE ABSAROKAS. CONTINUITY HAD A ISOLATED SHOWERS AND THUNDERSTORMS
ACROSS THOSE AREAS INTO THE EARLY EVENING AND WE LEFT THIS IN
ALTHOUGH MOST AREAS WILL BE DRY. ELSEWHERE...ESPECIALLY WEST OF THE
DIVIDE...IT LOOKS TO BE THROUGH TONIGHT. ANY ISOLATED SHOWERS AND
THUNDERSTORMS EAST OF THE DIVIDE SHOULD END THIS EVENING. AS FOR
MONDAY...IT LOOKS TO BE A SIMILAR DAY TO SUNDAY ALTHOUGH WITH EVEN
LESS CONVECTION. I CAN NOT RULE OUT A STRAY THUNDERSTORM OVER THE
NORTHERN BIG HORN RANGE BUT THE COVERAGE IS SO SMALL WE DECIDED TO
LEAVE IT OUT OF THE FORECAST FOR NOW. IT LOOKS TO BE ANOTHER HOT DAY
WITH ABOVE NORMAL TEMPERATURES ACROSS THE AREA. WESTERLY BREEZES
WILL ONCE AGAIN BLOW ACROSS SOUTHERN WYOMING WITH ANOTHER AFTERNOON
OF NEAR CRITICAL TO CRITICAL FIRE CONDITIONS LOOKING FAIRLY LIKELY.

.LONG TERM...MONDAY NIGHT THROUGH SUNDAY

FROM WEST TO EAST...MODEST RIDGE/TROF PATTERN ACROSS CONUS
TODAY...BECOMING MORE AMPLIFIED AS THE WEEK PROGRESSES. SO WARM/HOT
AND DRY FOR THE MOST PART THROUGH AT LEAST MID WEEK. WED...POSSIBLE
WEAK MOISTURE RETURN BEGINS...SO VERY LOW END POPS AROUND
CWA...MAINLY IN THE EAST. THURS...INDICATIONS FOR MORE IN THE WAY OF
MOISTURE RETURN...HOWEVER LR MODEL DIFFERENCES WITHIN THE BOUNDARY
LAYER DO NOT EXUDE CONFIDENCE IN THIS SCENARIO AND MAY BE SOMEWHAT
SLOWER TO PROCEED THAN MODELS ARE INDICATING...SO CUT BACK A BIT ON
THE HIGH HOPES FOR MOISTURE THIS DAY. HOWEVER... THURSDAY COULD BE
SLIGHTLY MORE INTERESTING IF PROGGED JET POSITIONS
HOLD...PARTICULARLY THROUGH FRIDAY. AS A MATTER OF FACT...FRIDAY AND
SATURDAY MAY VERY WELL BE THE PAY-OFF DAYS FOR PRECIP...WITH ALL
MODELS POINTING TOWARDS A TREND FOR A BETTER UPPER LEVEL RIDGE AND
SFC THERMAL LOW SET-UP FOR ALLOWING MOISTURE FROM THE SOUTH INTO OUR
REGION. WILL ASSESS THIS POSSIBILITY MORE CLOSELY AS WEEK
PROGRESSES.

OTHERWISE...TEMPERATURES ALSO TREND JUST SLIGHTLY LOWER...MOSTLY
THROUGH THE ACTION OF BETTER CHANCES FOR INCREASED MOISTURE AND
CLOUDS.

&&

.AVIATION.../00Z ISSUANCE/

VFR CONDITIONS WILL PREVAIL THROUGH 00Z MONDAY. A DRIER AIRMASS WILL
THEN PREVAIL OVER THE AREA THIS EVENING .  A STRAY SHOWER OR
THUNDERSTORM WILL BE POSSIBLE MAINLY EAST OF I-25 UNTIL AROUND 2Z.
WINDS WILL TREND SIMILAR TO SATURDAY WITH W-NW SFC WINDS AT 10-20KTS
WEST OF THE DIVIDE PRIMARILY THROUGH 02Z MONDAY. WINDS WILL LIGHTEN
AS THE ATMOSPHERE DECOUPLES TONIGHT. TOMORROW LOOKS TO BE A MAINLY
DRY DAY FOR ALL TAF SITES. A WESTERLY BREEZE WILL DEVELOP ACROSS
SOUTHERN WYOMING...ESPECIALLY AROUND KRKS AFTER 18Z.
&&

.FIRE WEATHER...

FIRE WEATHER CONDITIONS WILL GRADUALLY IMPROVE TONIGHT AS
TEMPERATURES FALL...RELATIVE HUMIDITY RISES AND WINDS LIGHTEN.
HOWEVER...THE MINIMUM RELATIVE HUMIDITY WILL BE IN THE UPPER SINGLE
DIGITS BOTH MONDAY AND TUESDAY AFTERNOON ACROSS THE LOWER ELEVATIONS
OF THE SOUTHERN HALF OF WYOMING. WINDS WILL BECOME BREEZY ONCE AGAIN
ON MONDAY AFTERNOON SO CRITICAL FIRE CONDITIONS WILL BE A
POSSIBILITY ONCE AGAIN FOR MONDAY AFTERNOON.
