Narrative:

While on an EMS flight to ZZZ1 to drop off the patient and transport to abc hospital I contacted approach for approval to fly into the class B airspace. I was given a code and was in contact with approach with heading and altitude reporting. While approaching the bridge I noticed that the WX that was being reported was not what I was encountering. WX reported was 1300 ft scattered; 1800 ft scattered; 2200 ft overcast with 10 mi; both at ZZZ1 and ZZZ2. There was this line of clouds just prior to the bridge. I descended to attempt to fly underneath the layer of clouds to stay VFR. At 500 ft MSL I entered the cloud bank and was IMC. I transition to the instruments and continued to fly straight ahead on a heading of 170 degrees. I contacted approach and informed them that I just went IMC and I needed radar vector to VFR conditions. Approach said maintain heading and continue to climb to VFR conditions or do I want an ILS approach to ZZZ1. I informed approach that I'm a VFR helicopter in IMC and that I would like vectors to known VFR conditions. Approach said continue to climb and report VFR on top. At 1650 ft MSL; approach asked me to turn to a heading of 270 degrees for jet traffic off of ZZZ2. I requested to maintain my heading of 170 degrees until I was VFR. The controller turned the traffic away from us and we continued to climb to 2500 ft MSL where we were VFR on top. I continued to climb to 3500 ft MSL with the approval of approach. The flight continued in VFR condition to ZZZ1 where I landed without any further problems. Callback conversation with reporter revealed the following information: pilot reported that he is an instrument rated ATP pilot.

Title: THE PLT OF AN EMS VFR HELI EXPERIENCED IMC CONDITIONS AND REQUESTED VECTORS ABOVE THE CLOUD DECK TO VMC.

Narrative: WHILE ON AN EMS FLT TO ZZZ1 TO DROP OFF THE PATIENT AND TRANSPORT TO ABC HOSPITAL I CONTACTED APCH FOR APPROVAL TO FLY INTO THE CLASS B AIRSPACE. I WAS GIVEN A CODE AND WAS IN CONTACT WITH APCH WITH HEADING AND ALT RPTING. WHILE APCHING THE BRIDGE I NOTICED THAT THE WX THAT WAS BEING RPTED WAS NOT WHAT I WAS ENCOUNTERING. WX RPTED WAS 1300 FT SCATTERED; 1800 FT SCATTERED; 2200 FT OVERCAST WITH 10 MI; BOTH AT ZZZ1 AND ZZZ2. THERE WAS THIS LINE OF CLOUDS JUST PRIOR TO THE BRIDGE. I DSNDED TO ATTEMPT TO FLY UNDERNEATH THE LAYER OF CLOUDS TO STAY VFR. AT 500 FT MSL I ENTERED THE CLOUD BANK AND WAS IMC. I TRANSITION TO THE INSTRUMENTS AND CONTINUED TO FLY STRAIGHT AHEAD ON A HEADING OF 170 DEGS. I CONTACTED APCH AND INFORMED THEM THAT I JUST WENT IMC AND I NEEDED RADAR VECTOR TO VFR CONDITIONS. APCH SAID MAINTAIN HDG AND CONTINUE TO CLB TO VFR CONDITIONS OR DO I WANT AN ILS APCH TO ZZZ1. I INFORMED APCH THAT I'M A VFR HELI IN IMC AND THAT I WOULD LIKE VECTORS TO KNOWN VFR CONDITIONS. APCH SAID CONTINUE TO CLB AND RPT VFR ON TOP. AT 1650 FT MSL; APCH ASKED ME TO TURN TO A HDG OF 270 DEGS FOR JET TFC OFF OF ZZZ2. I REQUESTED TO MAINTAIN MY HDG OF 170 DEGS UNTIL I WAS VFR. THE CTLR TURNED THE TFC AWAY FROM US AND WE CONTINUED TO CLB TO 2500 FT MSL WHERE WE WERE VFR ON TOP. I CONTINUED TO CLB TO 3500 FT MSL WITH THE APPROVAL OF APCH. THE FLT CONTINUED IN VFR CONDITION TO ZZZ1 WHERE I LANDED WITHOUT ANY FURTHER PROBS. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: PLT RPTED THAT HE IS AN INSTRUMENT RATED ATP PLT.
