Narrative:

While descending to enter the hold for weather; the left hp high light illuminated; and then went out after a few seconds while the captain was still getting her manual out of her flight bag. The light then illuminated again and stayed on. The captain and I went through the non normal checklist while holding; which included closing the left hp and bleed and determining if there were any unusual smells or temperatures in the aircraft. The captain contacted the flight attendant; who said nothing was unusual in the back. The procedure ends with us landing at the nearest suitable airport. We asked ATC for priority to be released from the hold in order to get to destination faster due to a problem with our air conditioning. We contacted dispatch and maintenance and told them of our plan to continue to destination since we were only about 50 miles away. Since everything on the aircraft appeared normal; our left bleed was shut and ATC released us quickly from the hold we did not feel it was necessary to declare an emergency or go to another airport. We continued and landed without incident.
