DAY 1 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0111 AM CDT FRI JUN 20 2008
VALID 201200Z - 211200Z
...NO CRITICAL AREAS...
...SYNOPSIS...
IN THE EAST...THE UPPER TROUGH WILL DOMINATE WHILE PORTIONS OF THE
SERN STATES WILL EXPERIENCE ANOTHER DAY OF CRITICALLY LOW RHS IN A
PREDOMINANT NWLY/WLY FLOW.
IN THE WEST...THE LOW SITUATED OFFSHORE OF BRITISH COLUMBIA WILL
BEGIN TO DEEPEN AND MOVE ONSHORE AS A JET AXIS DIGS INTO THE
BACKSIDE OF THE TROUGH. THIS WILL BEGIN A BREAKDOWN OF THE RIDGE
OVER THE PACIFIC NORTHWEST...AND ALLOW FOR SWLY WINDS TO OVERSPREAD
NRN CA/NV AND OR/WA/ID. IN CALIFORNIA...TWO SHORT WAVES MOVING INTO
THE COAST MAY SUPPORT DRY THUNDERSTORMS IN THE AFTERNOON.
...PORTIONS OF THE PACIFIC NORTHWEST...
THE LOW OFFSHORE OF BRITISH COLUMBIA WILL FINALLY BEGIN TO SHIFT
CLOSER TO THE COAST...OVERSPREADING SWLY WINDS ACROSS A LARGE AREA.
ALTHOUGH SUSTAINED WINDS WILL BE SOMEWHAT MARGINAL...STEEP LOW LEVEL
LAPSE RATES AND DEEP MIXING WILL PROMOTE GUSTY WINDS...ESPECIALLY ON
THE ERN SLOPES OF THE CASCADES. TEMPERATURES IN THE 80S TO 90S WITH
RELATIVE HUMIDITIES IN THE TEENS WILL BE COMMON.
...CALIFORNIA...
AROUND THE BASE OF THE TROUGH...TWO SHORT WAVES CAN BE SEEN
APPROACHING THE CALIFORNIA COAST...WITH EMBEDDED CONVECTION AND
OCCASIONAL LIGHTNING STRIKES OVER THE PACIFIC. THESE WAVES SHOULD
MOVE ONSHORE AT PEAK HEATING...PROVIDING LIFT IN CONCERT WITH
FAVORABLE UPSLOPE SUPPORT ALONG THE COASTAL MOUNTAINS. MID LEVEL
MOISTURE INCREASE SUPPORTED BY WV IMAGERY AND FAVORABLE LIFT WILL BE
CONDUCIVE FOR HIGH BASED THUNDERSTORMS THAT WILL THEN MOVE INTO THE
VALLEYS. INVERTED-V TYPE PROFILES WITH STEEP LOW LEVEL LAPSE RATES
IN PEAK HEATING WILL PRODUCE GUSTY AND ERRATIC WINDS BENEATH DRY
THUNDERSTORMS WHICH WILL AGITATE ANY ONGOING FIRES. LIGHTNING
STRIKES WILL BE CAPABLE OF STARTING ADDITIONAL FIRES.
...SWRN STATES...
HOT AND DRY CONDITIONS WILL CONTINUE UNDER AN UPPER RIDGE. STRONG
HEATING AND SURFACE TEMPERATURES INTO THE UPPER 90S TO NEAR 115 F
WILL ENHANCE FIRE THREAT IN RAIN PARCHED AREAS DESPITE LIGHT WINDS.
...INLAND SC/GA/AL/WRN FL PANHANDLE...
PREDOMINANT NWLY/WLY FLOW WILL ALLOW FOR THE DRIER AIR MASS TO
PERSIST FOR ONE MORE DAY AWAY FROM THE IMMEDIATE COASTS.
TEMPERATURES IN THE 80S AND LOWER 90S WILL ALLOW AFTERNOON RELATIVE
HUMIDITIES TO DROP INTO THE MID TO UPPER 20S...WHILE CLOSER TO THE
FL COAST RELATIVE HUMIDITIES NEAR 30 TO 35 WILL BE LIKELY. DESPITE
LIGHT WINDS...LACK OF RECENT RAINFALL AND DROUGHT CONDITIONS ACROSS
A LARGE PORTION OF THE SOUTHEAST WILL ENHANCE THE FIRE THREAT.

DAY 2 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0214 AM CDT FRI JUN 20 2008
VALID 211200Z - 221200Z
...NO CRITICAL AREAS...
...SYNOPSIS...
IN THE WEST...A NEGATIVELY TILTED TROUGH WILL FINALLY SHIFT
ONSHORE...OVERSPREADING STRONGER SWLY WINDS ACROSS PORTIONS OF THE
PACIFIC NORTHWEST. DRY THUNDERSTORMS WILL BE POSSIBLE IN THE
AFTERNOON CREATING GUSTY AND ERRATIC WINDS. ACROSS THE SWRN
STATES...HOT AND DRY CONDITIONS WILL PERSIST ONCE AGAIN WITH
TEMPERATURES INTO THE LOW 100S TO NEAR 115 DEGREES F.
IN THE EAST...UPPER TROUGHING WILL DOMINATE ONCE AGAIN...ALTHOUGH
RELATIVE HUMIDITIES WILL RECOVER ACROSS THE SERN STATES. THIS WILL
LIMIT THE FIRE DANGER.
...WA/OR/WRN ID/NRN CA/NV...
DOUBLE BARREL LOW SEEN ON SATELLITE IMAGERY THIS MORNING OFFSHORE OF
THE BRITISH COLUMBIA/PAC NW COAST WILL FINALLY SHIFT ONSHORE AND
BECOME MORE NEGATIVELY TILTED BY SATURDAY/DAY 2. SWLY JET AXIS AND
MID LEVEL MOISTURE WILL OVERSPREAD THE AREA AT PEAK AFTERNOON
HEATING. TEMPERATURES INTO THE MID TO UPPER 80S AND LOWER 90S WILL
ALLOW RELATIVE HUMIDITIES TO DROP INTO THE TEENS ACROSS A WIDESPREAD
AREA...WHILE STEEP LOW LEVEL LAPSE RATES AND DEEP MIXING WILL
PROMOTE GUSTY WINDS AT THE SURFACE. GIVEN INCREASE IN MID LEVEL
MOISTURE WHICH IS SUPPORTED BY WV IMAGERY THIS MORNING...AND
MARGINAL INSTABILITY...DRY THUNDERSTORM DEVELOPMENT WILL BE POSSIBLE
IN THE AFTERNOON. ANY STORMS THAT DO DEVELOP IN GREATER MOISTURE
HAVE THE POTENTIAL TO BE SOMEWHAT LONGER LIVED GIVEN FAVORABLE DEEP
SHEAR PROFILES AND STRONG MID LEVEL FLOW. INVERTED-V TYPE PROFILES
WILL SUPPORT GUSTY AND ERRATIC WINDS NEAR THESE THUNDERSTORMS WHICH
MAY AGITATE ONGOING FIRES...WHILE LIGHTNING STRIKES MAY IGNITE
ADDITIONAL FIRES.
...SWRN STATES...
ANOTHER DAY OF HOT AND DRY CONDITIONS WILL PERSIST ACROSS THE SWRN
STATES WITH HIGH HAINES INDICES. TEMPERATURES WILL CLIMB OVER 100
DEGREES UP TO NEAR 115 IN LOWER VALLEYS. ALTHOUGH WINDS WILL BE
SOMEWHAT MARGINAL...GUSTY NLY WINDS MAY BE POSSIBLE THROUGH THE
VALLEYS OF SRN CA IN THE AFTERNOON.
