AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ELKO NV
207 AM PDT FRI JUN 28 2013

.SYNOPSIS...RECORD BREAKING HEAT WILL CONTINUE THROUGH EARLY NEXT
WEEK AS A STRONG HIGH PRESSURE SYSTEM SITS OVER THE WESTERN UNITED
STATES. ENOUGH MOISTURE MAY SEEP IN TO TRIGGER SOME ISOLATED DRY
THUNDERSTORMS FOR THE NEXT FEW AFTERNOONS.

&&

.SHORT TERM...TODAY THROUGH SATURDAY.

MAINLY CLEAR SKIES AROUND THE LKN CWFA THIS MORNING AND VERY
MILD. THERE ARE STILL A FEW REMNANT BUT DISSIPATING CLOUDS SHOWING
UP ALOFT OF THE HIGHWAY 50 CONVERGENCE ZONE. LIGHTING OVER THE
SIERRAS EXTINGUISHED AROUND MIDNIGHT. THERE IS A TIGHT SURFACE
PRESSURE GRADIENT OVER NORTHERN UTAH THE IS PRODUCING NORTHERLY
WIND GUSTS TO 20 MPH AT KENV AND TEMPERATURES HELD IN THE MID 80S
WELL AFTER MIDNIGHT. OTHERWISE WINDS ARE ALMOST NON-EXISTENT
EXCEPT FOR THE SOUTHERLY DRAINAGE AT ELY. TEMPERATURES AS OF 1 AM
PDT ARE GENERALLY RANGING FROM 65 TO 75. THE MODELS REMAIN IN
AGREEMENT FOR THE SHORT TERM.

AN EXCESSIVE HEAT WARNING IS IN EFFECT FOR MOST ZONES...EXCEPTIONS
BEING THE RUBY MOUNTAINS AND NORTHERN ELKO COUNTY. HIGH PRESSURE
WILL BEGIN ITS RETROGRADE MOVEMENT TO THE WEST WHILE AMPLIFYING.
AS THE RIDGE AXIS ALIGNS OVER AZ/UT...THE FLOW AROUND THE HIGH
WILL SEND A SURGE OF HEAT FAR INTO THE CWFA. H7 TEMPS ARE
PROJECTED ABOVE 20C...A VERY RARE OCCURRENCE...HOWEVER MODELS HAVE
BEEN PERSISTENT WITH THIS ASPECT. ISOLATED THUNDERSTORMS ARE
EXPECTED TO DEVELOP AND WILL PROBABLY BE LIMITED TO HIGHER
ELEVATIONS AS CLOUDS DEVELOP OVER THE MOUNTAIN PEAKS.
TODAY...PRIOR TO CENTRAL HIGH PRESSURE REACHING THE UT/NV BORDER...THE PW
VALUES WILL BE ABOVE .7...WITH SOME DRYING EXPECTED SATURDAY. THUS
TODAY MAY BE THE BEST CHANCE FOR THUNDERSTORM ACTIVITY. HUMBOLDT
COUNTY WILL NOT LIKELY SEE ANY TS ACTION. HIGH TEMPERATURES IN THE
VALLEYS WILL GENERALLY RANGE FROM 95 TO 105.

.LONG TERM...SATURDAY NIGHT THROUGH NEXT THURSDAY. AN INTENSE HEAT
WAVE WILL CONTINUE ACROSS NEVADA SUNDAY THROUGH TUESDAY. RECORD HIGH
TEMPERATURES, BOTH AFTERNOON HIGHS AND MORNING LOWS, WILL CONTINUE.
THE PROLONGED NATURE OF THE HOT TEMPERATURES WILL PLACE SIGNIFICANT
STRESS ON LIVESTOCK, PETS, AND VEGETATION. 700 MB TEMPERATURES HOVER
NEAR 20-22C SUNDAY THROUGH TUESDAY, WITH MOST VALLEYS REACHING
99-109 DEGREES EACH DAY. SOME MODEL GUIDANCE IS EVEN HOTTER THAN
THIS, FORECASTING RIDICULOUS NUMBERS SUCH AS 115 NEAR BATTLE
MOUNTAIN AND NEAR 120 IN THE HOTTEST PARTS OF NYE COUNTY. BELIEVE
THESE MODELS ARE OVERDONE WITH THE HEAT, BUT SUFFICE IT TO SAY THE
HEAT WILL BE DANGEROUS FOR THOSE THAT DON'T RESPECT IT. 00Z ECMWF
REMAINS CONSISTENT SLOWLY RETROGRADING THE IMMENSE UPPER HIGH
NORTHWESTWARD ACROSS THE GREAT BASIN. MOISTURE AND INSTABILITY WILL
BE EMBEDDED WITHIN THE ANTICYCLONE'S CIRCULATION, SO THE CHANCE OF
CONVECTION WILL NOT BE ZERO, BUT IT WILL NOT BE GREAT EITHER.
MAINTAINED ISOLATED MAINLY DRY THUNDERSTORMS IN THE FORECAST EACH
AFTERNOON AND EVENING. FOR ANY CONVECTION THAT MANAGES TO FORM,
MEANINGFUL RAINFALL IS NOT EXPECTED, JUST VIRGA AND GUSTY OUTFLOWS.

WEDNESDAY AND THURSDAY...COMPUTER MODELS REMAIN CONSISTENT
FORECASTING THE UPPER HIGH AND HEAT WAVE TO COLLAPSE QUICKLY.
RAPIDLY FALLING HEIGHTS WILL ALLOW HIGH TEMPERATURES TO RETURN TO
MUCH MORE BEARABLE LEVELS. IN ADDITION, 00Z ECMWF SUGGESTS
CONVECTION OPPORTUNITIES WILL INCREASE BY NEXT THURSDAY, BUT KEPT
THUNDERSTORM COVERAGE CAPPED AT ISOLATED FOR NOW. BT

&&

.AVIATION...VFR/SKC THROUGH 18Z. AFTER 18Z, INTENSE HEAT WILL FUEL
INSTABILITY AND ISO/SCT -TSRA 18-04Z. CONVECTION WILL FAVOR THE
HIGHER TERRAIN AND MOVE SLOWLY, THUS DIRECT AFFECTS ON THE TERMINALS
SHOULD BE MINIMAL. INCLUDED A VCTS/CB MENTION AT KEKO/KELY/KWMC WITH
A 20% CHANCE OF CONVECTION AFFECTING KEKO, 15% KELY, AND 10% KWMC.
KTPH WILL STAY DRY. EXTENSIVE CUMULUS FIELD NEAR 12K FT AGL NEAR
KEKO/KELY BY 00Z. ANY -TSRA WILL BE HIGH-BASED AND PRODUCE GUSTY
OUTFLOW WINDS TO 40 KTS. BT

&&

.FIRE WEATHER...HIGH PRESSURE WILL BRING HOT AND DRY CONDITIONS TO
NORTHERN NEVADA THROUGH THE PERIOD. MODELS ARE SHOWING A SLIGHT
INCREASE IN THE MID-LEVEL MOISTURE FOR FRIDAY AFTERNOON. HAVE KEPT
ISOLATED DRY THUNDERSTORMS IN THE FORECAST WITH A SLIGHT INCREASE
IN AREAL COVERAGE. BEST CHANCES FOR DRY THUNDERSTORMS FRIDAY AFTERNOON
WILL BE IN FIRE ZONES 454...455...AND 457. STORM MOTION WILL
GENERALLY BE IN THE 5 TO 10 KNOT RANGE. ANOTHER ROUND OF ISOLATED
DRY THUNDERSTORMS ARE EXPECTED FOR SATURDAY AFTERNOON AS
WELL...WITH STORM MOTIONS AGAIN BEING IN THE 6-12 KNOT RANGE. THE
RIDGE AXIS WILL GRADUALLY SHIFT WEST FROM SUNDAY THROUGH EARLY
NEXT WEEK...WITH ISOLATED DRY THUNDERSTORMS POSSIBLE EACH
AFTERNOON...MAINLY OVER THE HIGH TERRAIN.
