    I have done something like this for achieving this task:

    in header file(.h)

    @interface RDViewController : UIViewController{
        UIImage *image ;
    @property (strong, nonatomic) IBOutlet MKMapView *mapView;
    @property (strong, nonatomic) IBOutlet UIActivityIndicatorView *activityIndicator;
    @property (strong, nonatomic) IBOutlet UIImageView *imageView; 

    in .m file

    @implementation RDViewController
    @synthesize mapView;
    @synthesize activityIndicator;
    @synthesize imageView;
    - (void)viewDidLoad
     NSURL *url = [NSURL URLWithString: 
        MapOverlay * mapOverlay = [[MapOverlay alloc] initWithImageData:[NSData dataWithContentsOfURL:url] withLowerLeftCoordinate:CLLocationCoordinate2DMake(21.652538062803, -127.620375523875420) withUpperRightCoordinate:CLLocationCoordinate2DMake(50.406626367301044, -66.517937876818)];
        [mapView addOverlay:mapOverlay];
        [super viewDidLoad];
        // Do any additional setup after loading the view, typically from a nib.
    - (void)viewDidUnload
        [self setImageView:nil];
        [self setMapView:nil];
        [self setActivityIndicator:nil];
        [super viewDidUnload];
        // Release any retained subviews of the main view.
        // e.g. self.myOutlet = nil;
    - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
        // Return YES for supported orientations
        return YES;
    #pragma Mark - MKOverlayDelgateMethods
    - (MKOverlayView *)mapView:(MKMapView *)mapView viewForOverlay:(id <MKOverlay>)overlay {
        MapOverlay *mapOverlay = overlay;
        MapOverlayView *mapOverlayView = [[MapOverlayView alloc] initWithOverlay:mapOverlay];
        return mapOverlayView;

    You need investigate MapKit overlays (MKOverlay). In your case you will be creating a MKPolygon.

    You will need to create an array of MKMapPoints from your weather radar data, then create a MKPolygon from these points and add it your map as an overlay.

    There is a sample Apple project called HazardMap which does something very similar to what you are trying to do, except in this case it is using earthquake data.

    Also check out the WWWDC 2011 presentation “Visualizing Information Geographically with MapKit”. Around the 30 minute mark they start talking about Overlays.

    Hope this helps.
