EVENT...ELEVATED CONVECTION WITH APPROACHING FRONT TO THE COAST...
.
SATELLITE ANALYSIS AND TRENDS...ELEVATED CONVECTION WITH SLIGHT COOLING
TO TOPS AS FRONTAL BAND APPROACHES WA AND OREGON COASTS.  AMSU 06Z 15KM
AREAL AVERAGE INSTANTANEOUS RAIN RATES HAD MAXED OUT AT 0.5"-0.75"/HR
NEAR 45.5N/128.5W.  BUT INDIVIDUAL CONVECTIVE CELLS MOVING AT BETTER
THAN 30KTS WHICH WOULD MAKE IT ALMOST IMPOSSIBLE FOR THESE RATES TO BE
REALIZED AT THE COAST AND INLAND.  A QUARTER TO HAVE THESE RATES WOULD
BE MORE REALISTIC ESPECIALLY IN OLYMPICS. HEART OF THE CELLS WITH FRONT
MAKING IT TO THE NW CA/SW OREGON BORDER COAST BY 12Z...W CENTRAL OREGON
COAST ABOUT THE SAME TIME...NW OREGON COAST ABOUT 1130Z...11-1130Z
W WA COAST.  AND THEN 3-5 HOURS INTO THE CASCADES.  FOR THE MOST PART
140 MILES SEPARATES DISTANCE BETWEEN CENTER OF HIGHEST PW MOISTURE (NEAR
1.0") WITH FRONT AND EASTERN EDGE OF DRIER AIR (PWS OF AROUND 0.5")
IN BACK OF THE FRONT AND WITH MAIN UPPER LEVEL LOW LIFTING NORTH INTO E
GULF OF ALASKA...FLAT STRATOCU TO BE MORE PREVALENT FOR WEAK INSTABILITY
SHOWERS BEHIND THE FRONT AS WELL.   WILL CONTINUE TO MONITOR.
