The letter was dated last Thursday, and it's Tuesday. The letter might not have reached the lawyer's desk until yesterday, and he might not even have read it yet, if he's in the middle of a trial or if he's on vacation. I'm not sure from your question whether the letter went to the judge from your lawyer, or from your lawyer to the judge, but I'd give you the same answer, either way.
If you have a lawyer in a pending case, you should absolutely not contact the judge directly in any way. It's improper, and all you will succeed in doing is at least annoying both the judge and your lawyer.
