SYNOPSIS...A VERY MOIST LOW PRESSURE SYSTEM OVER THE REGION WILL
CONTINUE TO PRODUCE SHOWERS AND THUNDERSTORMS WITH POCKETS OF
HEAVIER RAINFALL ESPECIALLY ACROSS NORTHERN NEVADA THROUGH
THURSDAY. AS WE APPROACH THE WEEKEND THE AREA WILL BECOME DRIER
WITH ISOLATED THUNDERSTORMS ACROSS NORTHERN NEVADA MAINLY NORTH OF
INTERSTATE 80.

SHORT TERM...TONIGHT THROUGH THURSDAY. ISOLATED TO SCATTERED
THUNDERSTORMS ARE FORMING ACROSS THE CWA MAINLY WHERE SOME HEATING
HAS OCCURRED. CAPE WILL APPROACH 1000 TO 1500 J/KG WHERE SOME
HEATING IS OCCURRING WITH PW'S UP TO 1.25" ACROSS NORTHERN NEVADA WITH PW'S
AROUND .75". THESE STORMS ARE VERY EFFICIENT RAIN PRODUCERS SO
AREAS OF FLASH FLOODING ARE POSSIBLE. OPTED TO NOT EXTEND FLASH
FLOOD WATCH FOR TOMORROW ALTHOUGH SOME LOCALIZED AREAS ACROSS
NORTHERN NEVADA COULD RECEIVE HEAVY RAIN AND SOME FLASH FLOODING BUT DID
NOT THINK THREAT WAS HIGH ENOUGH TO WARRANT A WATCH. TONIGHT THE
LOW PRESSURE SYSTEM WILL MEANDER ACROSS NORTHERN NEVADA WITH
RAINSHOWERS AND A FEW LIGHTNING STRIKES POSSIBLE WITH POCKETS OF
HEAVIER RAIN MAINLY ACROSS NORTHERN ELKO COUNTY AND HUMBOLDT
COUNTY.

WEDNESDAY THE LOW PRESSURE WILL STILL HANG TOUGH ACROSS NORTHERN
NEVADA WITH AREAS OF HEAVIER RAINFALL AND ISOLATED TO SCATTERED
THUNDERSTORMS WITH PW'S OF AN INCH OR BETTER TO CONTINUE ACROSS
NORTHERN NEVADA WITH PW'S OF .50 TO .75" ACROSS CENTRAL NEVADA
WHERE LESS SHOWERS AND THUNDERSTORMS ARE EXPECTED.

THURSDAY THE LOW PRESSURE TROUGH WILL FINALLY BEGIN TO PUSH EAST
WITH BEST CHANCE OF THUNDERSTORMS ACROSS NORTHEAST NEVADA IN ELKO
COUNTY. PW'S WILL BE SLIGHTLY ABOVE .75 IN NORTHEAST NEVADA WITH
LOWER PW'S ELSEWHERE SO THUNDERSTORMS WILL BE LESS LIKELY ACROSS
FAR WESTERN AND SOUTHERN PARTS OF THE CWA AS THE AIRMASS DRIES AND
BECOME MORE STABLE.

LONG TERM...THURSDAY NIGHT THROUGH TUESDAY. SHORT WAVE ENERGY AND
INSTABILITY WILL BRING A THREAT OF THUNDERSTORMS TO NORTHERN NV
THROUGH THE WEEKEND. DIFFERENCES CROP UP BETWEEN THE GFS/EURO MONDAY
AND TUESDAY WHICH WILL HAVE AN IMPACT ON THE SENSIBLE WEATHER. GFS
HOLDS ON TO SOME MOISTURE AND INSTABILITY ACROSS NORTHEAST NV MONDAY
WHILE THE EURO BRINGS A SLUG OF MOISTURE INTO NORTHERN AND CENTRAL
NV FROM THE SOUTH AROUND FOUR CORNERS HIGH. THE GFS WAITS UNTIL
TUESDAY TO BRING UP THIS MOISTURE BY WHICH TIME THE EURO PUSHES THE
MOISTURE EAST OF NEVADA.

AVIATION...A VERY MOIST AIRMASS WILL BRING NUMEROUS SHOWERS AND
SCATTERED THUNDERSTORMS TO NRN NV THROUGH THIS EVENING. CONDITIONS
WILL DROP TO MVFR UNDER THE HEAVIER SHOWERS. ACROSS CENTRAL NV
ISOLATED SHOWERS AND THUNDERSTORMS COULD IMPACT THE KELY TERMINAL
THROUGH 03Z.

FIRE WEATHER...WIDESPREAD SHOWERS AND ISOLATED TO SCATTERED THUNDERSTORMS
WITH WETTING RAINS WILL CONTINUE ACROSS NORTHERN NEVADA WITH DRIER
AIR MOVING INTO CENTRAL NEVADA AS WE APPROACH WEDNESDAY. BY THE
WEEKEND MUCH DRIER CONDITIONS EXPECTED WITH ISOLATED THUNDERSTORMS
ACROSS NORTHERN NEVADA MAINLY NORTH OF INTERSTATE 80.
