  .SYNOPSIS...Cold morning low temperatures will quickly warm for a 
  very nice Sunday across the area. Expect much lighter winds for 
  Sunday. Warming temperatures are in store for the week with 
  continued chilly mornings.  
   
  && 
   
  .DISCUSSION...Light winds, clear skies, and a very dry airmass in 
  place over Northern Arizona have allowed temperatures to cool  
  rapidly as expected this morning. Some of our traditional cold  
  spots like Bellemont and Tusayan have cooled to around 19F as of 2 
  AM. Expect to see temperatures drop a few more degrees over the  
  next couple of hours with many other locations dropping into the  
  low to mid 20s along the high terrain.  
   
  Temperatures will warm back up into the mid 60s across the high 
  terrain and to mid to upper 70s across the valleys for Sunday. The 
  low that brought us the extreme winds will begin to lift  
  northward through the day Sunday. With the low still to our north, 
  afternoon west to southwest breezes will still occur.These will  
  be much lighter than we have seen the past two days. With  
  temperature around 10 degrees warmer than yesterday and much  
  lighter breezes, it should be a great Sunday to get outdoors.  
   
  A ridge will build in across the area through the midweek with 
  quiet weather and warming temperatures expected. As a very dry  
  airmass looks to stay in place for the next few days with clear  
  nights forecast, expect continued. Be sure to cover sensitive 
  vegetation and be sure to shelter animals inside.
