Add an extra cost based on cart items weight to Woocommerce shipping rates

I have the code following placed in functions.php

function shipping_weight_fee( $cart ) {      if ( is_admin() && ! defined( 'DOING_AJAX' ) )          return;            $extraFee  = 0;      $total_weight = 0;        // Loop though each cart item      foreach ( $cart->get_cart() as $cart_item ) {          // Get product id          $product_id = $cart_item['product_id'];            // Get weight          $product_weight = $cart_item['data']->get_weight();            // NOT empty           if ( ! empty( $product_weight )  ) {              // Quantity              $product_quantity = $cart_item['quantity'];                // Add to total              $total_weight += $product_weight * $product_quantity;          }      }        if ( $total_weight > 10 ) {                    $extraFee = 20;      }  }  add_action( 'woocommerce_cart_calculate_fees', 'shipping_weight_fee', 10, 1 );  

How can I get $extraFee from first code snippet to work in following code: I tried with global but it does not work. I believe the second code runs first but I am not sure.

add_filter( 'woocommerce_package_rates', 'custom_shipping_costs', 20, 2 );  function custom_shipping_costs( $rates, $package ) {            foreach( $rates as $rate_key => $rate ){          // Excluding free shipping methods          if( $rate->method_id != 'free_shipping'){                // Set rate cost              $rates[$rate_key]->cost +=  $extraFee + 3;            }      }      return $rates;  }  

Please help, thank You!
