i have a question regarding BECOMING.
Ex. BECMG 0204, so there will be a gradual change from 02 to 04
my question is does the condition stay the same after 04 until there is another change or would it go back to the previous condition before 02?

BECMG indicates a gradual change in the weather. So a gradual change will commence at 02 and be complete by 04. After 04 the original weather will have been replaced by the weather described after BECMG. Those new conditions will persist until the end of the validity period or until another change is indicated. Nowadays the times will include the date. So, assuming it was the 15th of the month, the change you describe will be written as BECMG 1502/1504.
