.PREV DISCUSSION... /ISSUED AT 312 AM /

SYNOPSIS...LOW PRESSURE COMBINED WITH A MOIST AIR MASS WILL BRING
WIDESPREAD SHOWERS AND ISOLATED TO SCATTERED THUNDERSTORMS TO THE
AREA THROUGH FRIDAY NIGHT. LOCALLY HEAVY RAIN IS LIKELY...WITH FLASH FLOODING
POSSIBLE. WARMER AND DRIER WEATHER IS EXPECTED OVER THE WEEKEND.
STARTING MONDAY...BREEZY AND DRY IS ANTICIPATED DURING THE UPCOMING WEEK.

SHORT TERM...TODAY THROUGH FRIDAY. RADAR THIS MORNING HAS BEEN
ACTIVE IN THE EAST...WITH ECHOS MAINLY OVER SOUTHWEST ELKO COUNTY.
LIGHT TO MODERATE RAIN...WITH A LIGHTNING STRIKE OR TWO...IS SEEN
IN THIS AREA. THE AREA OF SHOWERS AND THUNDERSTORMS IS MOVING WEST
AND SOUTH. WHITE PINE COUNTY COULD ALSO BE GETTING LIGHT
RAIN...BUT RADAR BEAM IS OVERSHOOTING.

AN UPPER LEVEL LOW SPINNING OVER THE AREA HAS BEEN RESPONSIBLE FOR
THE RAIN AND THUNDERSTORMS. SOME LOCATIONS IN WHITE PINE COUNTY
HAVE REPORTED VERY ROBUST AMOUNTS OF ONE HALF TO ONE INCH OF
RAINFALL OVER THE PAST DAY. THE UPPER LEVEL SYSTEM WITH A VERY
MOIST AIR MASS WILL CONTINUE TO PROVIDE THE AREA WITH MORE
PRECIPITATION. MODELS CONTINUE TO SHOW THE LOW SLOWLY MOVING
NORTHWARD...TAKING UP A POSITION SOMEWHERE IN ELKO COUNTY BY LATE
THIS AFTERNOON. MODELS ARE SHOWING CAPE VALUES OF 300 TO 700
J/KG...ALONG WITH SLOW STORM MOTIONS OF 5 TO 10 KNOTS AND CORFIDI
VECTOR MAGNITUDES OF O TO 5 KNOTS. LIFTED INDICES REMAIN BELOW
ZERO OVER THE ENTIRE FORECAST AREA...WITH K INDICES BETWEEN
35-40C. ALL OF THESE VALUES POINT TOWARDS SLOW MOVING AND/OR
TRAINING CELLS THAT COULD PRODUCE PERIODS OF LOCALIZED HEAVY RAIN.
THE FLASH FLOOD WATCH HAS BEEN EXTENDED IN TIME THROUGH 0700 UTC
ON SATURDAY...OR MIDNIGHT SATURDAY MORNING. POP GRIDS LOOKED GOOD
AND ONLY MADE MINOR ADJUSTMENTS. AFTERNOON HIGHS TODAY ARE
EXPECTED TO AGAIN BE ON THE COOL SIDE...EXCEPT FOR MAYBE HUMBOLDT
COUNTY WHERE A LITTLE MORE SUN WILL BRING HIGHS IN THE LOW 80S.

THE UPPER LEVEL IS NOT EXPECTED TO GO VERY FAR AND WILL WOBBLE
AROUND NORTHERN NEVADA THROUGHOUT THE NIGHT. AS A RESULT...UNSETTLED
CONDITIONS WILL CONTINUE THIS EVENING INTO TOMORROW MORNING...AND HAVE
LEFT ISOLATED THUNDERSTORMS WITH RAIN OVER THE FORECAST AREA. SOME
STORMS COULD PRODUCE HEAVY RAIN AS THE INGREDIENTS DON'T CHANGE
MUCH. OVERNIGHT LOWS WILL BE WARM DUE TO A MOIST ATMOSPHERE AND
EXTENSIVE CLOUD COVER.

FOR FRIDAY...UPPER LEVEL LOW WILL BE POSITIONED SOMEWHERE IN
NORTHEAST NEVADA AND NORTHWEST UTAH. THE ATMOSPHERE WILL CONTINUE
TO REMAIN RICH IN MOISTURE AND UNSTABLE...WITH PRECIPITABLE WATER
VALUES OF AROUND 0.80 TO ONE INCH AND LIFTED INDICES BELOW ZERO.
K-VALUES CONTINUE TO REMAIN ROBUST WITH VALUES IN THE MID TO UPPER
30C RANGE...AND CORFIDI VECTOR MAGNITUDES WILL BE WEAK. THE BEST
CAPE VALUES ARE FORECAST TO BE IN ELKO AND WHITE PINE COUNTIES.
THE MAIN THREAT LOCALIZED MODERATE TO HEAVY RAIN CONTINUES FOR THE
EASTERN HALF OF THE FORECAST AREA. THE SUN ANGLE IS PRETTY HIGH
STILL...SO ANY HEATING WILL HELP US TO DESTABILIZE RAPIDLY.
OVERALL...HIGH TEMPERATURES WILL RUN NEAR TO JUST ABOVE NORMAL.

LONG TERM...FRIDAY NIGHT THROUGH NEXT WEDNESDAY. THE LOW PRESSURE
THAT HAS BROUGHT PLENTIFUL RAIN TO THE REGION WILL BE MOVING EAST OF
THE AREA WITH LINGERING SHOWERS AND THUNDERSTORMS ACROSS THE EASTERN
HALF OF THE CWA THROUGH SATURDAY. SUNDAY A TRANSITORY RIDGE WILL
MOVE ACROSS THE GREAT BASIN WARMING TEMPERATURES SEVERAL DEGREES AND
BRINGING DRIER WEATHER. MONDAY A COLD FRONT WILL SWEEP ACROSS THE REGION AS
AN UPPER LEVEL TROUGH DIPS ACROSS NORTHERN NEVADA. THIS FRONT WILL
BE DRY WITH SOME HIGH CLOUDS POSSIBLE AND A BIT BREEZY WITH THIS
SYSTEM. BY TUESDAY WESTERLY FLOW WILL DOMINATE THE REGION HOWEVER
MODELS DIFFERENCES START TO EMERGE WITH ECMWF BRINGING ANOTHER COLD
FRONT ACROSS THE AREA EARLY ON WEDNESDAY WHILE THE GFS IS SLOWER
BRINGING THE COLD FRONT THROUGH ABOUT 18 HOURS LATER THAN ECMWF.
TEMPERATURES WILL CONTINUE TO BE ABOVE NORMAL THROUGH THE PERIOD
EVEN WITH THE COOLING TREND EARLY NEXT WEEK.

AVIATION...VFR CIGS AND VIS WILL PREVAIL NEXT 24 HOURS AT MOST
TERMINALS...HOWEVER MVFR AND IFR CIGS AND OCCASIONALLY LOWERED VIS IS
POSSIBLE AT KELY AS SHOWERS AND THUNDERSTORMS REMAIN IN THE AREA.
THIS ACTIVITY SHOULD BE LESS FREQUENT AT KEKO KWMC AND KTPH WITH
LESS THREAT OF LOWERED CIGS/VIS. THUNDER IS POSSIBLE MAINLY THIS
AFTERNOON AND EVENING WITH 30 TO 40 PERCENT CHANCES AT ALL
TERMINALS.

FIRE WEATHER...LOOK FOR WIDESPREAD RAIN SHOWERS AND ISOLATED
TO SCATTERED THUNDERSTORMS TODAY AND FRIDAY. A SLOW DRYING
OUT PERIOD IS EXPECTED DURING THE WEEKEND. BREEZY CONDITIONS
ARE POSSIBLE NEXT WEEK WITH DRIER CONDITIONS.
