FORECAST IS ON TRACK AND NO CHANGES REQUIRED.
..STOPPKOTTE.. 07/08/2010
.PREV DISCUSSION... /ISSUED 0201 AM CDT THU JUL 08 2010/
...SYNOPSIS...
AN UPPER RIDGE WILL BUILD OVER THE WRN U.S. WITH WARM AIR SPREADING
NWD ACROSS THE GREAT BASIN AND INTO THE PACIFIC NW. ENOUGH MOISTURE
WILL BE PRESENT ALONG AN OLD FRONTAL BOUNDARY FROM NRN NV INTO NRN
CA FOR ISOLATED THUNDERSTORMS...SOME DRY. TO THE E...THE RIDGE OVER
THE ERN STATES WILL WEAKEN AS AN UPPER TROUGH MOVES EWD ACROSS THE
GREAT LAKES...AND A WEAK UPPER LOW DRIFTS WWD ACROSS THE WRN
ATLANTIC...BRINGING MOISTURE FOR THUNDERSTORMS INLAND.
...NRN CA INTO NRN NV...
CONDITIONS TODAY WILL BE SIMILAR TO YESTERDAY WITH ISOLATED TO
SCATTERED THUNDERSTORMS FORMING OVER THE SIERRA BY LATE
AFTERNOON...EWD ACROSS NRN NV WHERE A WEAK FRONT WILL REMAIN. THE
ISOLATED ACTIVITY OVER NRN NV WILL ALL BE DRY...BUT A BIT MORE
MOISTURE POINTS W MAY RESULT IN A MIXTURE OF WET AND DRY
STORMS...ESPECIALLY GIVEN SLOW STORM MOTIONS.
...AL/GA/CAROLINAS...
IT WILL BE VERY WARM OVER THE SERN STATES WITH HIGHS NEAR 100 OVER
GA AND SC. THIS WILL RESULT MIN RH IN THE 20 PERCENT RANGE BY
AFTERNOON AND LOW LEVEL LAPSE RATES WILL BE STEEP AND THE ATMOSPHERE
UNSTABLE. HOWEVER...WINDS WILL BE LIGHT. TO THE NE...ELY WINDS OFF
THE ATLANTIC WILL HELP RAISE MOISTURE LEVELS INTO THE
CAROLINAS...ESPECIALLY ERN NC AND VA...WHERE AFTERNOON THUNDERSTORMS
ARE EXPECTED. THESE STORMS WILL CONTAIN HEAVY RAIN AND ALSO VERY
GUSTY WINDS AT TIMES.

DAY 2 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0120 PM CDT THU JUL 08 2010
VALID 091200Z - 101200Z
...NO CRITICAL AREAS...
...NRN CA...SRN ORE...NRN NV...SRN ID INTO SW MT...
THUNDERSTORM ACTIVITY WILL INCREASE DURING THE AFTERNOON AND
SCATTERED TO WIDESPREAD THUNDERSTORMS ARE EXPECTED. ALONG THE
IMMEDIATE COASTAL RANGE OF NRN CA...STORMS WILL BE A MIX OF WET AND
DRY. ELSEWHERE...PW VALUES AROUND A HALF INCH WILL LEAD TO DRY
THUNDERSTORMS. HOWEVER...GIVEN SLOW STORM MOTIONS SOME WETTING RAIN
WILL BE POSSIBLE. FUEL CONDITIONS OVERALL REMAIN UNFAVORABLE FOR A
WIDESPREAD THREAT OF NEW FIRES SO WILL HOLD OFF FOR NOW ON ISSUING A
CRITICAL AREA FOR DRY LIGHTNING.
ASIDE FROM THUNDERSTORM ACTIVITY...DRY CONDITIONS WITH RH VALUES IN
THE 20 PERCENT RANGE AND LOCALLY TERRAIN ENHANCED WINDS AROUND 15-20
MPH WILL CREATE MARGINAL CRITICAL CONDITIONS IN THE COLUMBIA GORGE
AREA OF N CNTRL ORE.
..STOPPKOTTE.. 07/08/2010
.PREV DISCUSSION... /ISSUED 0205 AM CDT THU JUL 08 2010/
...SYNOPSIS...
AN UPPER RIDGE WILL REMAIN OVER THE W WITH MID LEVEL MOISTURE
SPREADING NWD BENEATH IT ACROSS THE GREAT BASIN AND INTO SRN
PORTIONS OF THE PACIFIC NW. WIDESPREAD WARM CONDITIONS WILL PERSIST
UNDER THE RIDGE...AND A LARGER AREA OF THUNDERSTORMS IS EXPECTED
COMPARED TO THE PREVIOUS FEW DAYS. TO THE E...A WEAK LEE TROUGH WILL
BE IN PLACE OVER GA AND SC FRI AFTERNOON WITH HOT AND DRY CONDITIONS
CONTINUING AND WITH LOCALLY GUSTY WINDS AHEAD OF A COLD FRONT.
...NRN CA...FAR SERN ORE...NRN NV...SRN ID...
MOISTURE WILL SPREAD NWWD BENEATH THE RIDGE ON FRIDAY. ISOLATED TO
SCATTERED STORMS ARE LIKELY IN THE SAME AREAS AS ON THUR...BUT ALSO
A BIT FARTHER N INTO OR/ID/WY. STEERING CURRENTS WILL REMAIN WEAK
ALOFT...THUS MANY STORMS WILL LIKELY PRODUCE RAIN. STILL...A
SIGNIFICANT NUMBER OF LIGHTNING STRIKES IS ANTICIPATED OVER A LARGE
AREA. MARGINAL FUEL CONDITIONS OVERALL MAY KEEP THE THREAT
SUB-CRITICAL ESPECIALLY ALONG AND N OF 42ND PARALLEL...BUT TRENDS
WILL CONTINUE TO BE MONITORED FOR THE NEED FOR A DRY THUNDER
CRITICAL FOR PORTIONS OF THE NRN GREAT BASIN.
...SERN GA...SC...
WITH A DEEPENING LEE LOW...SWLY WINDS OF 10-15 MPH ARE LIKELY ALONG
WITH HOT TEMPERATURES OF 95 - 100 AND MIN RH IN THE 30 PERCENT
RANGE. THIS WILL BE GOOD FOR MARGINAL FIRE WEATHER CONCERNS FOR A
FEW HOURS DURING THE AFTERNOON.
