CLEX-9 October 18th, 2001 Operations

Synopsis

• The CLEX-9 forecast team has decided to stand by all operations for Thursday, October 18th.
  
  
• Weather Forecast (made at 1500 MDT 10/17/01):

  
            Mission Forecast: The upper level ridge over the Rockies today is expected 
            to give way to a trof bringing some PAC moisture along.  The associated sfc 
            front is expected to pass LBF Thursday morning and the hopes for this mission 
            are to sample the clouds near this front.  Subsidence behind the front will 
            quickly clear the area of significant clouds, hence the earlier mission time.
  
  
            Weather Outlook:  On Friday, NW’erly winds will dominate as the upper level 
            trof continues to progress eastward and a ridge builds back over the Rockies.  
            The opportunity for some moisture to work its way over the ridge towards LBF 
            in NW’erly flow is good.  The timing of this scenario has potential to mesh with 
            the 1800Z Terra overpass.

  Morning Update (made at 0300 MDT 10/18/01): 
  
            The CLEX-9 morning forecast team has decided to stand down all operations 
            today (17 October 2001).  
  
            The upper-level cloud deck moved through this morning and did not show any signs 
            of having mid-level clouds associated with it that would be of interest for a 
            morning CLEX-9 mission.  John Davis reports mostly clear conditions over North 
            Platte (with only high cirrus present).  
  
            The next band of moisture from an approaching upper level trough should start 
            advecting into our target region later today/tonight.  Will have to see how the 
            models handle the upper level dynamics associated with this next system....
