MAINE WAS STILL NOT IN A DROUGHT AT THE END OF JUNE. CALCULATED 
SOIL MOISTURE FROM THE CLIMATE PREDICTION CENTER (CPC) REMAINS 
ELEVATED THROUGHOUT MAINE. EVAPORATION AT CARIBOU THROUGHOUT THE

RAINFALL FOR JULY. NORMAL JULY LOW TEMPERATURES FOR THE REGION ARE
55 TO 60 DEGREES AND NORMAL HIGH TEMPERATURES ARE UPPER 70S TO 
AROUND 80 DEGREES.
