SYNOPSIS...PLENTY OF MOISTURE AND A WEATHER DISTURBANCE WILL
COMBINE TO PRODUCE A THREAT OF SHOWERS AND THUNDERSTORMS WEDNESDAY
AND THURSDAY. HIGH PRESSURE WILL BUILD BACK IN ON FRIDAY FOR A
RETURN TO WARM AND DRY WEATHER THIS WEEKEND.

SHORT TERM...SHOWERS AND THUNDERSTORMS ARE DUMPING UP TO 3/4 INCH
OF RAIN AND PEA SIZED HAIL OVER MUCH OF OUR AREA. THESE STORMS ARE
BEING CAUSED BY A DEFORMATION ZONE SPLITTING OUR AREA FROM
NORTHEAST TO SOUTHWEST. THE ONLY EXCEPTION IS HUMBOLDT COUNTY
WHICH HAS LESS ACTIVITY. THESE STORMS WILL FIRE UP AGAIN THURSDAY
THOUGH DECREASED IN COVERAGE AND INTENSITY. ON FRIDAY THE
DEFORMATION ZONE WILL SHIFT EAST...LEAVING US WITH PARTLY CLOUDY
SKIES. WE STILL NEED TO KEEP AN EYE ON THE FLASH FLOODING
POTENTIAL IN EUREKA AND ELY.

LONG TERM...RIDGING ON FRIDAY AND SATURDAY WILL WARM TEMPERATURES
AND KEEP DRY CONDITIONS IN PLACE. SUNDAY AND MONDAY WILL SEE
FLATTENING OF THE RIDGE WITH TIGHTER GRADIENTS. FOR THIS REASON
WILL PLACE WINDY IN THE EXTENDED.

.EKO...NONE.
