AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ELKO NV
634 AM PDT WED APR 28 2010

.SYNOPSIS...WINDS WILL CONTINUE TO BE GUSTY ACROSS EASTERN NEVADA THROUGH
THIS MORNING. RAIN AND SNOW SHOWERS WILL REDEVELOP THIS AFTERNOON.
UNSETTLED WEATHER MAY LAST INTO EARLY NEXT WEEK AND TEMPERATURES
WILL BE COOLER THAN NORMAL.
&&

.UPDATE...WILL LET THE HIGH WIND WARNING FOR EXTREME EASTERN ELKO
COUNTY EXPIRE AS SCHEDULED AT 7AM PDT. WINDS ARE GENERALLY IN THE
BREEZY TO WINDY CATEGORY BUT HAVE DIMINISHED TO BELOW WARNING
CRITERIA. THERE IS THE POSSIBILITY FOR AN ADDITIONAL WIND EVENT
LATE THURSDAY ACROSS EASTERN NEVADA AS ANOTHER SURFACE LOW DIVES
SOUTH FROM IDAHO PRODUCING A FAVORABLE NORTH/NORTHWEST FLOW WITH A
TIGHTENED PRESSURE GRADIENT.

OTHERWISE SCATTERED SHOWERS CONTINUE ACROSS ELKO COUNTY IN THE
VICINITY OF ELKO AND SPRING CREEK INCLUDING THE RUBY MOUNTAINS
WITH LIGHT ACCUMULATIONS ON THE HIGHER HILLS AND VERY LITTLE IN
THE VALLEYS...AS TEMPERATURE HOVER NEAR THE FREEZING MARK THIS
MORNING. WILL SEE REDEVELOPMENT OF BREEZY WINDS FOR MOST AREAS
TODAY. SCATTERED TO NUMEROUS RAIN AND SNOW SHOWERS WILL ALSO REDEVELOP AS
THE DAY WEARS ON.
&&

.PREV DISCUSSION... /ISSUED AT 347 AM /

SYNOPSIS...WINDS WILL CONTINUE TO BE GUSTY THROUGH EARLY THIS MORNING
AS RAIN AND SNOW SHOWERS BEGIN TO FILL IN BEHIND THE COLD FRONT. UNSETTLED
WEATHER IS ON TAP AGAIN DURING THE DAY TODAY THROUGH THE REMAINDER OF
THE WEEK AND AFTERNOON TEMPERATURES WILL BE COOLER THAN NORMAL. &&

SHORT TERM...TODAY THROUGH FRIDAY. WINDS CONTINUE TO SLOWLY
DIMINISH ACROSS MOST VALLEY LOCATIONS THIS MORNING. A HIGH WIND
WARNING REMAINS IN EFFECT FOR EASTERN ELKO COUNTY ZONE 33 THROUGH
7AM PDT/8AM MDT. THE FRONT MOVED THROUGH WENDOVER ABOUT 05Z AND
WINDS BRIEFLY DIMINISHED BEFORE REGAINING STRENGTH. WINDS ARE
CURRENTLY GUSTING IN THE 30S AT WENDOVER HOWEVER POST-FRONTAL
WINDS COULD STILL PUNCH THROUGH HIGH WIND CRITERIA. SHOWER
ACTIVITY WILL INCREASE AS THE WINDS CONTINUE TO DIMINISH THIS IN
THE EARLY MORNING HOURS. RADAR IS INDICATING MOST OF THE ACTIVITY
IS OVER NORTHERN ELKO COUNTY HOWEVER AREAL COVERAGE IS EXPANDING
EASTWARD THROUGH SOUTHWEST/SOUTH-CENTRAL ELKO COUNTY ATTM. RAIN
BEGAN CHANGING OVER AROUND 1130PM AT EKO LAST EVENING WITH
TEMPERATURES IN THE MID 30S. SNOW ACCUMULATIONS SHOULD BE LIGHT
OVERNIGHT...WITH UP TO TWO INCHES POSSIBLE IN THE VALLEYS AND
HIGHER AMOUNTS ABOVE 6500 FEET.

MODELS SEEM TO VERY SIMILAR IN SOLUTION ON THE LATEST RUN. THE
MAIN TROUGH AXIS FROM WHICH THE CURRENT STRONG COLD FRONT EMANATED
WILL MOVE FROM ITS PRESENT LOCATION THROUGH WASHINGTON/OREGON TO
NEAR THE 4-CORNERS AREA BY FRIDAY AFTERNOON. THIS SLOW MIGRATION
WILL LEND ITSELF TO UNSETTLED WEATHER FOR THE GREAT BASIN THE
ENTIRE PERIOD. THE NORTHWEST TO NORTH UPPER FLOW TRANSITION WILL
KEEP FEEDING COLD AIR INTO THE FORECAST AREA. TEMPERATURES TODAY WILL
BE VERY COLD FOR THIS TIME OF YEAR WITH 700 MB TEMPERATURES AROUND
-10C TO -13C. HOWEVER DAYTIME TEMPERATURES MAXING OUT AROUND 40
SHOULD HELP WARD OFF DAYTIME SNOW ADVISORIES AT LOWER ELEVATIONS
THE NORTHERN MOUNTAINS COULD SEE SEVERAL INCHES OF NEW SNOW
TODAY BUT SEE NO CONCERN ATTM. THURSDAY AND FRIDAY...AS THE LOW
CENTRALIZES OVER EASTERN MONTANA THEN THE DAKOTAS...SHOWERS SHOULD BECOME
MORE SCATTERED AND THERE IS QPF DISCREPANCY BETWEEN THE MODELS AS
THE FLOW TURNS NORTH.

AS FAR AS WINDS GO...WITH THE UPPER JET FLOW DIGGING SOUTH OF THE
AREA...TONOPAH SHOULD BE WINDY FROM THE NORTH TODAY BUT DO NOT
ANTICIPATE HIGH WINDS FOR AN EXTENDED PERIOD ATTM. FOR
WENDOVER...A SURFACE FEATURE DIVING SOUTH THROUGH IDAHO INTO
EASTERN NEVADA THURSDAY EVENING MAY PRODUCE SOME POTENTIAL
ADVISORY WINDS FOR SEVERAL HOURS BUT TOO UNCERTAIN ATTM.

LONG TERM...FRIDAY NIGHT THROUGH NEXT WEDNESDAY. THE LONGWAVE
PATTERN FOR THIS FORECAST PERIOD WILL COMMENCE WITH AN UPPER LEVEL
RIDGE BUILDING INTO THE WEST. HOWEVER ON TUESDAY...A PACIFIC LOW
WILL ENCROACH UPON THE GREAT BASIN...FLATTENING OUT THE
RIDGE...RESULTING IN ZONAL FLOW ACROSS NORTHERN NEVADA. TWO DISTINCT
VORT LOBES WILL BE EMBEDDED WITHIN THIS UPPER LEVEL TROF...THE FIRST
PRIMARILY IMPACTING IDAHO AND THE SECOND...TAKING A MORE SOUTHERLY
TRAJECTORY ...CARVING ITS WAY ACROSS NORTHERN NEVADA. THIS SECOND
SHORTWAVE IS EXPECTED EARLY NEXT WEDNESDAY. THE MODELS ARE NOT IN
SYNC REGARDING THE TIMING OF THIS UPPER LEVEL DISTURBANCE. THE GEM
AND THE ECMWF ARE IN ONE CAMP...WHILE THE GFS AND DGEX ARE IN
ANOTHER CAMP...HEDGED AFTER 156 HRS. WHAT IS CERTAIN IS THAT THE
SECOND IMPULSE WILL BE ABLE TO BRING MOISTURE DEEPER INTO NORTHERN
NEVADA...IN PARTICULAR ELKO AND HUMBOLDT COUNTIES...AND AT THIS TIME
EXPECT MOST OF THE QPF NORTH OF I-80...AND FOR THIS SYSTEM TO
PREDOMINATELY BE A RAIN EVENT...WITH SNOW ABOVE 6800 FEET.

AVIATION...CURRENTLY AT 10Z OR 3AM...SURFACE DATA REVEALS THAT THE
LOW-LEVEL PRIMARY BOUNDARY IS EXITING THE EASTERN PORTION OF THE
CWA...MEANWHILE...THE TAIL END OF THE UPPER LEVEL JET IS STILL OVER
CENTRAL NEVADA. THE STRONGEST WINDS FROM THIS EVENT HAVE MOVED OUT
OF THE SILVER STATE...ALTHOUGH GUSTY CONDITIONS WILL REFORM OVER
PORTIONS OF THE SILVER STATE WEDNESDAY AFTERNOON. RADAR DATA
INDICATE THAT THERE ARE SEVERAL SMALL BANDS OF PRECIPITATION MOVING
THROUGH THE AREA...BUT SIGNIFICANT RAIN/SNOW ACTIVITY IS NOT
EXPECTED AT THE TAF SITES. CEILINGS WILL GRADUALLY IMPROVE.
