No, the sentence "It's cold today, remember to bring your jacket" is not a run-on sentence.
A run-on sentence occurs when two or more independent clauses are joined together without proper punctuation or conjunctions. In this case, we only have one independent clause, "It's cold today," followed by a dependent clause, "remember to bring your jacket." The two clauses are correctly joined by using a comma to separate them. So, it is not a run-on sentence.
Yes it is it would be better if two sentences :)
