INTO WESTERN NV AND ID/SOUTHWEST MT FOR DRY THUNDERSTORMS...
...CRITICAL FIRE WEATHER AREA FOR INTERIOR SOUTHERN CA/SOUTHERN
NV...
...CRITICAL FIRE WEATHER AREA FOR CENTRAL/EASTERN UT AND NORTHERN AZ
FOR DRY THUNDERSTORMS...
...CRITICAL FIRE WEATHER AREA FOR CENTRAL/EASTERN WA AND NORTHEAST
ORE INTO NORTHERN ID/NORTHWEST MT...
...SYNOPSIS...
POTENTIALLY ACTIVE FIRE WEATHER DAY ANTICIPATED TODAY ACROSS A LARGE
PORTION OF THE WESTERN STATES. PROMINENT UPPER RIDGE OVER THE
WESTERN STATES WILL BEGIN TO WEAKEN...LARGELY OWING TO A
SHORTWAVE TROUGH CROSSING THE WESTERN CANADIAN PROVINCES. AN UPPER
LOW CROSSING NORTHERN CA IS EXPECTED TO INDUCE DRY THUNDERSTORMS
ACROSS THE CA SIERRAS/ORE CASCADES INTO ID/WESTERN MT. OTHER MAINLY
DRY THUNDERSTORMS ARE LIKELY ACROSS PORTIONS OF CENTRAL/EASTERN UT
AND NORTHERN AZ.
...CRITICAL FIRE WEATHER AREA - CA SIERRAS AND CENTRAL/EASTERN ORE
INTO WESTERN NV AND ID/SOUTHWEST MT...
PRIMARY CONDITIONS: DRY THUNDERSTORMS AND HOT/DRY CONDITIONS
WITH SUFFICIENT MID LEVEL MOISTURE AND LARGE SCALE FORCING FOR
ASCENT...AN UPPER LOW CROSSING NORTHERN CA IS EXPECTED TO YIELD
ISOLATED TO SCATTERED DRY THUNDERSTORMS THIS AFTERNOON/EVENING
FROM THE CA SIERRAS AND CENTRAL/EASTERN ORE INTO WESTERN NV AND
ID/SOUTHWEST MT. AMIDST HOT/DRY CONDITIONS...NEW FIRE STARTS ARE
LIKELY GIVEN THE HIGH LIGHTNING IGNITION EFFICIENCIES. A HOT/DEEPLY
MIXED BOUNDARY LAYER WILL PROMOTE STRONG DOWNDRAFTS...WITH
GUSTY/ERRATIC WINDS NEAR ANY THUNDERSTORMS.
...CRITICAL FIRE WEATHER AREA - INTERIOR SOUTHERN CA/SOUTHERN NV...
PRIMARY CONDITIONS: VERY HOT/DRY CONDITIONS WITH GUSTY WINDS
ON THE SOUTHEAST/EASTERN PERIPHERY OF THE UPPER LOW ACROSS NORTHERN
CA...AN ENHANCED BELT OF MID LEVEL FLOW AND AMPLE PRESSURE GRADIENT
WILL SUPPORT BROAD SCALE GUSTY SOUTH/SOUTHWEST WINDS FROM INTERIOR
CA INTO SOUTHERN NV TODAY. TEMPERATURES WILL REMAIN QUITE HOT...WITH
NEAR RECORD HIGH TEMPERATURES AGAIN POSSIBLE...AS WELL AS VERY LOW
RH VALUES IN THE SINGLE DIGITS. IN ADDITION...A FEW STRAY DRY
THUNDERSTORMS CANNOT BE RULED OUT ACROSS PORTIONS OF INTERIOR
SOUTHERN CA/SOUTHERN NV.
...CRITICAL FIRE WEATHER AREA - CENTRAL/EASTERN UT AND NORTHERN
AZ...
PRIMARY CONDITIONS: DRY THUNDERSTORMS
AS MID LEVEL MOISTURE CONTINUES TO GRADUALLY DEVELOP WESTWARD
THROUGH THE FOUR CORNERS REGION...MAINLY DRY THUNDERSTORMS ARE AGAIN
LIKELY ACROSS CENTRAL/EASTERN UT AND NORTHERN AZ THIS
AFTERNOON/EVENING. WITH LIMITED RAINFALL...NEW LIGHTNING IGNITIONS
ARE POSSIBLE...IN ADDITION TO STRONG/GUSTY WINDS IN ASSOCIATION WITH
THUNDERSTORM DOWNDRAFTS.
...CRITICAL FIRE WEATHER AREA - CENTRAL/EASTERN WA AND NORTHEAST ORE
INTO NORTHERN ID/NORTHWEST MT...
PRIMARY CONDITIONS: HOT/DRY CONDITIONS AND GUSTY WINDS
AS THE UPPER RIDGE BREAKS DOWN...MODERATELY STRONG/GUSTY WINDS ARE
LIKELY EAST OF THE ORE/WA CASCADES INTO NORTHERN ID/NORTHWEST MT AS
A COLD FRONT ADVANCES EASTWARD ACROSS THE REGION. IN ADDITION TO THE
COLD FRONTAL PASSAGE/GUSTY WINDS...RECORD OR NEAR RECORD HEAT IN
SOME LOCATIONS AND CRITICALLY LOW RH VALUES WILL FURTHER COMPOUND
THE HEIGHTENED FIRE DANGER.

0514 AM CDT FRI JUL 06 2007
VALID 071200Z - 081200Z
...CRITICAL FIRE WEATHER AREA FOR CA SIERRAS/SOUTHEAST ORE/SOUTHERN
ID/WESTERN WY AND MUCH OF NV/UT FOR DRY THUNDERSTORMS...
...CRITICAL FIRE WEATHER AREA FOR INTERIOR SOUTHERN CA/SOUTHERN
NV...
...SYNOPSIS...
WESTERN STATES UPPER RIDGE WILL CONTINUE TO WEAKEN...WITH NEARLY
ZONAL WESTERLIES BECOMING ESTABLISHED ACROSS THE NORTHERN TIER OF
STATES. AS ONE OR MORE SUBTLE SHORTWAVE TROUGHS PIVOT AROUND THE
FLATTENING UPPER RIDGE...SCATTERED MAINLY DRY THUNDERSTORMS ARE
AGAIN EXPECTED ACROSS THE CA SIERRA INTO THE GREAT BASIN AND
ADJACENT INTERMOUNTAIN WEST.
...CRITICAL FIRE WEATHER AREA - CA SIERRAS/SOUTHEAST ORE/SOUTHERN
ID/WESTERN WY AND MUCH OF NV/UT...
PRIMARY CONDITIONS: DRY THUNDERSTORMS AND HOT/DRY CONDITIONS
SIMILAR TO FRIDAY...SCATTERED MAINLY DRY THUNDERSTORMS ARE EXPECTED
ON SATURDAY FROM THE CA SIERRAS/SOUTHEAST ORE INTO MUCH OF NV/UT AND
SOUTHERN ID/WESTERN WY. A WEAK UPPER LOW WILL CONTINUE TO PIVOT
AROUND THE FLATTENING UPPER RIDGE...AND AMPLE LARGE SCALE ASCENT/MID
LEVEL MOISTURE WILL BE SUPPORTIVE OF SCATTERED MAINLY DRY
THUNDERSTORMS GIVEN A HOT/DEEPLY MIXED BOUNDARY LAYER. WITH DROUGHT
CONDITIONS IN MOST AREAS AND RECENT RECORD/NEAR RECORD HEAT...HIGH
LIGHTNING EFFICIENCIES SUGGEST NEW FIRE STARTS ARE A DISTINCT
POSSIBILITY. IN ADDITION...GUSTY/ERRATIC DOWNDRAFT WINDS CAN BE
EXPECTED IN VICINITY OF ANY THUNDERSTORMS.
...CRITICAL FIRE WEATHER AREA - INTERIOR SOUTHERN CA/SOUTHERN NV...
PRIMARY CONDITIONS: HOT TEMPERATURES/LOW RH AND GUSTY WINDS
GIVEN THE FLATTENING UPPER RIDGE...TEMPERATURES MAY BE SLIGHTLY
COOLER ACROSS THE REGION ON SATURDAY...HOWEVER GENERAL PERSISTENCE
OF HOT TEMPERATURES AND VERY LOW RH VALUES SUPPORTS A CONTINUANCE OF
A CRITICAL FIRE RISK ACROSS PORTIONS OF INTERIOR SOUTHERN CA AND
SOUTHERN NV. EXTREME DROUGHT EXISTS ACROSS MOST OF THIS REGION...AND
MODERATE/GUSTY WINDS ARE AGAIN EXPECTED SATURDAY.
