Narrative:
Our dispatcher, dispatched us with no mention of the intensity of the rain associated with a cold front passing through eastern half of PA. We encountered heavy rain and constant moderate, after bordering on severe, turbulence. The radar was only depicting light to moderate rain in any direction. After landing in philadelphia, the captain wrote up the radar as not functioning properly and talked again to dispatch, who released us to allentown with no mention of potentially hazardous conditions. They arranged for us to take another airplane, one which we felt had a good radar. The wind shifted from 120 degrees to 290 degrees at phl and now with a good radar we departed, thinking the front was now east of philadelphia and any lingering cells could be avoided. We again encountered heavy rain, moderate to close to severe turbulence and not much depiction on the radar. After landing at abe we found our dispatcher had again dispatched us for our next leg to baltimore. The captain however 'pressed' the dispatcher for an exact explanation of their ground based radar depiction and after 10 mins and 2 calls pried enough out of him to realize we had been dispatched 3 times into almost solid level 3 rain with embedded level 4 and level 5 cells. Needless to say, we did not depart until all WX had moved to the east. Our company puts a lot of pressure on dispatch to get all flts out on time. Also, I don't think our dispatchers understand the significance of what they see on their radar screens nor do they understand the limitations of airborne radar due to attenuation. So I believe it is a fear of delaying or canceling a flight that tends to keep our dispatchers from 'volunteering' too much information. If we would have known the extent of the WX, we would have easily understood our radar problem and would have probably refused dispatch on first leg.

Title: FO COMPLAINT REGARDING THE AIRLINE MGMNT POLICY AND DISPATCHER ATTITUDE OF DISPATCHING PAX FLTS INTO SEVERE WX CONDITIONS WITHOUT PROVIDING ADEQUATE INFO TO THE FLCS.
Narrative: OUR DISPATCHER, DISPATCHED US WITH NO MENTION OF THE INTENSITY OF THE RAIN ASSOCIATED WITH A COLD FRONT PASSING THROUGH EASTERN HALF OF PA. WE ENCOUNTERED HVY RAIN AND CONSTANT MODERATE, AFTER BORDERING ON SEVERE, TURB. THE RADAR WAS ONLY DEPICTING LIGHT TO MODERATE RAIN IN ANY DIRECTION. AFTER LNDG IN PHILADELPHIA, THE CAPT WROTE UP THE RADAR AS NOT FUNCTIONING PROPERLY AND TALKED AGAIN TO DISPATCH, WHO RELEASED US TO ALLENTOWN WITH NO MENTION OF POTENTIALLY HAZARDOUS CONDITIONS. THEY ARRANGED FOR US TO TAKE ANOTHER AIRPLANE, ONE WHICH WE FELT HAD A GOOD RADAR. THE WIND SHIFTED FROM 120 DEGS TO 290 DEGS AT PHL AND NOW WITH A GOOD RADAR WE DEPARTED, THINKING THE FRONT WAS NOW E OF PHILADELPHIA AND ANY LINGERING CELLS COULD BE AVOIDED. WE AGAIN ENCOUNTERED HVY RAIN, MODERATE TO CLOSE TO SEVERE TURB AND NOT MUCH DEPICTION ON THE RADAR. AFTER LNDG AT ABE WE FOUND OUR DISPATCHER HAD AGAIN DISPATCHED US FOR OUR NEXT LEG TO BALTIMORE. THE CAPT HOWEVER 'PRESSED' THE DISPATCHER FOR AN EXACT EXPLANATION OF THEIR GND BASED RADAR DEPICTION AND AFTER 10 MINS AND 2 CALLS PRIED ENOUGH OUT OF HIM TO REALIZE WE HAD BEEN DISPATCHED 3 TIMES INTO ALMOST SOLID LEVEL 3 RAIN WITH EMBEDDED LEVEL 4 AND LEVEL 5 CELLS. NEEDLESS TO SAY, WE DID NOT DEPART UNTIL ALL WX HAD MOVED TO THE E. OUR COMPANY PUTS A LOT OF PRESSURE ON DISPATCH TO GET ALL FLTS OUT ON TIME. ALSO, I DON'T THINK OUR DISPATCHERS UNDERSTAND THE SIGNIFICANCE OF WHAT THEY SEE ON THEIR RADAR SCREENS NOR DO THEY UNDERSTAND THE LIMITATIONS OF AIRBORNE RADAR DUE TO ATTENUATION. SO I BELIEVE IT IS A FEAR OF DELAYING OR CANCELING A FLT THAT TENDS TO KEEP OUR DISPATCHERS FROM 'VOLUNTEERING' TOO MUCH INFO. IF WE WOULD HAVE KNOWN THE EXTENT OF THE WX, WE WOULD HAVE EASILY UNDERSTOOD OUR RADAR PROB AND WOULD HAVE PROBABLY REFUSED DISPATCH ON FIRST LEG.
