Tornado in Nevada, June 27, 2004

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ELKO NV
1230 PM PDT SUN JUN 27 2004

.SYNOPSIS...HIGH PRESSURE WILL CONTINUE TO BRING WARM TEMPERATURES TO
THE GREAT BASIN THROUGH NEXT WEEK. AFTERNOON HEATING COMBINED WITH
MOISTURE ALOFT WILL BRING A SLIGHT RISK FOR AFTERNOON AND EVENING
THUNDERSTORMS THROUGH THE WEEK...MAINLY ACROSS WESTERN AND NORTHERN
NEVADA.
&&

.DISCUSSION...CONVECTION A LITTLE SLOWER TO START OFF TODAY WITH
MORE EXTENSIVE CLOUDS EARLIER THIS MORNING INHIBITING HEATING.
THUNDERSTORMS HAVE FORMED OVER SOUTHERN ZONES OVER PAST HOUR OR TWO.
THIS MORNINGS SOUNDING VERY SIMILAR TO YESTERDAY MORNINGS...THOUGH
JUST A BIT MORE MOIST AND UNSTABLE. NO SIGNIFICANT CHANGES MADE TO
THE FORECAST. CWA REMAINS BETWEEN TROF JUST OFF CALIFORNIA COAST AND
BROAD RIDGE TO OUR NORTHEAST.

IMMEDIATE CONCERN WILL BE ANY STRONG STORMS THIS AFTERNOON AND
EVENING. WV IMAGERY SHOWS WEAK VORT/SHORTWAVE JUST SOUTH OF CWA
MOVING SLOWLY NORTHWARD. INITIATION OF CONVECTION OVER SOUTHERN CWA
SEEMS TO BE ON NORTHERN EDGE OF THIS FEATURE. BEST CHANCE AGAIN
TODAY APPEARS TO BE ELKO COUNTY WITH CAPES OVER 1000 J/KG AND LI/S
OF -2 TO -3C. BEST LOW LEVEL CONVERGENCE IS SOUTH OF THE AREA THAT
HAS THE BEST INSTABILITY...SO THIS COULD INHIBIT CONVECTION
SLIGHTLY. HOWEVER...WITH APPROACHING VORT...HIGH INSTABILITY OVER
NORTHEAST CWA AND GOES DPI SHOWING LI/S NEAR -3C AND PW APPROACHING 1
INCH OVER SOME AREAS OF ELKO COUNTY...LIKELY TO BE SOME STRONG SLOW
MOVING STORMS WITH LOCALIZED HEAVY RAIN.

FOR TOMORROW...CONVECTIVE FOCUS WILL BE ACROSS THE NORTHERN CWA
AGAIN. SOME INSTABILITY REMAINS OVER SOUTHERN CWA...SO INCREASED
POPS SLIGHTLY THERE. FOR REMAINDER OF SHORT TERM...DECREASING
CHANCES OF PRECIP WITH BEST POSSIBILITY NEAR NORTHERN AND NORTHWEST
CWA. MODELS IN DECENT AGREEMENT IN EXTENDED PERIOD. UPPER LOW DRIFTS
SLOWLY EAST TOWARD END OF WEEK. HAVE CONTINUED TO BROAD BRUSH LOW
POPS...MAINLY WEST AND NORTH.

.LKN WATCHES/WARNINGS/ADVISORIES...NONE
