"Chance drizzle"

       My weather source on the web had an upcoming prediction today which reminded me of my  grandmother.  It was brief, appearing in this chart-like form:

                      Today                                       Tonight
       
                      Sunny                                    Chance Drizzle


I could hear it spoken with my Grandmother's slightly broken English,  Yiddish intonation, and especially that marker of her Eastern European or Russian Jewish background in word choice--"chance drizzle"-- minus any preposition, peculiar to look at, but perfectly understandable, especially to me.
