CORRECTED WATCH LINE

.SHORT TERM...
VERY ISOLATED SHALLOW CONVECTION HAS LASTED ALL NIGHT OVER THE GREAT
BASIN WHICH HAS PRODUCED SOME GUSTY OUTFLOW WINDS AND EVEN A TRACE
OF RAIN AT KNFL. THIS CONVECTION WAS ASSOCIATED WITH A THETA-E RIDGE
RAPIDLY BUILDING INTO THE AREA AND LIFT PROVIDED BY THE WEAK LOW
OVER THE CENTRAL CALIFORNIA COAST. THE CONVECTION OVERNIGHT HAS
HELPED TO MOISTEN THE MID LEVELS WHICH IS ALSO BEING AIDED BY SELY
FLOW ADVECTING MOISTURE INTO THE AREA. INSTABILITY IS ONLY MARGINAL
BUT WITH EXTRA LIFT PROVIDED BY THE LOW CANNOT RULE OUT
THUNDERSTORMS FROM ANY PORTION OF THE CWA LATER TODAY. BELIEVE THAT
CONVECTION WILL FIRST DEVELOP OVER NRN WASHOE AND PERSHING COUNTIES
LATER THIS MORNING WHERE MOISTURE TONGUE AND PVA IS GREATEST. PRECIP
IN THESE STORMS IS MOST LIKELY TO BE MIXED...RAIN IS POSSIBLE UNDER
THE CORE WITH DRY LIGHTNING ON THE FRINGES. ALSO SLOW CELL MOVEMENT
DUE TO LIGHT STEERING WINDS WILL KEEP RAINFALL LIMITED...SO DECIDED
TO GO WITH A FIRST PERIOD FIRE WEATHER WATCH FOR DRY LIGHTNING IN
THOSE AREAS. AS DIURNAL HEATING INCREASES THIS AFTERNOON...ISOLATED
SHOWERS WILL DEVELOP OVER THE MAJORITY OF THE CWA WITH THE GREATEST
COVERAGE OVER MONO AND MINERAL COUNTIES WHERE THE BEST MOISTURE AND
SURFACE CONVERGENCE IS. STILL TORN ON NOCTURNAL STORMS TONIGHT OVER
THE FAR SRN OR ERN PORTIONS OF THE CWA WHERE PV UNDULATION/UPPER
LEVEL FRONT COULD CAUSE ENOUGH DIVERGENCE ALOFT TO KEEP THINGS
GOING. WILL LET DAY SHIFT DECIDE ON CONVECTION FOR 06-12Z TONIGHT.

SWLY FLOW ALOFT INCREASES SLIGHTLY OVER THE NRN ZONES SUNDAY WHICH
MAY BEGIN TO DRY THEM OUT. ELSEWHERE...STILL CANT RULE OUT AFT/EVE
SHOWERS AND THUNDERSTORMS. ONCE AGAIN THE INSTABILITY IS ONLY
MARGINAL...SO BEST CHANCES WILL BE OVER MONO/MINERAL COUNTIES WHERE
CONVERGENCE/DIVERGENCE COUPLET IS GREATEST. A SHORTWAVE MOVING INTO
THE PACNW SUNDAY NIGHT INTO MONDAY FURTHER INCREASES THE DRIER SWLY
FLOW OVER THE NRN HALF OF THE CWA. THIS WILL LIMIT ANY CHANCES FOR
CONVECTION MONDAY TO THE TYPICAL HIGHWAY 50 CONVERGENCE ZONE. JORDAN

&&

.LONG TERM...TUESDAY THROUGH FRIDAY...
MEDIUM RANGE MODELS ARE CONSISTENT IN BRINGING AN UPPER TROUGH
ACROSS THE CWA WEDNESDAY INTO THURSDAY. AS SHOWN YESTERDAY THE
HEIGHTS REMAIN QUITE HIGH WITH THIS SYSTEM AS DYNAMICS AND
PRECIPITATION STAY NORTH OF NV. BREEZY TO WINDY CONDITIONS AHEAD OF
AND WITH THE TROUGH TUESDAY AND WEDNESDAY AFTERNOONS WILL COMBINE
WITH LOW RELATIVE HUMIDITIES TO CREATE SOME FIRE WEATHER CONCERNS.
ON THURSDAY AND FRIDAY THE TROUGH LIFTS NORTHEAST AND HIGH PRESSURE
REBUILDS ACROSS THE SIERRA AND WESTERN NV. TEMPERATURES WILL DIP
BELOW NORMAL WEDNESDAY AND THURSDAY THEN REBOUND RAPIDLY ON FRIDAY.
