CLEX-9 October 9th, 2001 Operations

Synopsis

• The CLEX-9 forecast team has decided to stand by operations for Tuesday, October 9th.
  
  
• Weather Forecast (made on 10/8/01):

            Weather for tomorrow looks favorable for clouds over North Platte.  
            Our biggest concerns are with precipitation and overlaying cirrus 
            clouds.  The morning update crew will be dealing with both of these 
            concerns.  An upper level system is moving into the NP area from the 
            NW bringing in weak PVA early on tomorrow.  Another weak disturbance 
            is moving in from the SW but should end up south and east of our target 
            area.  If the NW weather disturbance comes in weak, then conditions 
            should be ripe for mid-level cloud sampling....
  
            Longer term:  Wednesday looks potentially good as this upper level 
            disturbance looks to still be in the NP area.  Surface precip might still 
            be an issue.  We will have to see how the models update tomorrow.  The 
            next weather disturbance looks to move into the region on Thursday/Friday 
            (not sure about the timing) and again has good potential (as of now) for 
            cloud cover.  The longer term MRF (and ECMWF) has the central US under a 
            large region of low pressure (centered over the Great Lakes) which has been 
            a very favorable pattern for mid-level cloud cover formation in the past.  
            Looks like an active week ahead for CLEX-9!

  Morning Update (made at 3:30 MDT on 10/9/01): 
  
            The CLEX-9 forecast team has decided to stand down operations for Tuesday, 
            October 9th. The lack of any non-precipitating target clouds within our 
            region of interest prompted this stand down decision.

Aircraft Operations

• No UW King Air Operations

North Platte, NE Ground Operations

• Summary: Test operations were performed
• Ground Instrument Status:

              The NOAA microwave radiometer is not archiving data.  
              This has been the case since 10/08/2001 at about 1500 
              GMT.  John Davis spoke with Brad Orr and we were unable 
              to correct the problem over the phone.  NOAA personnel 
              will arrive on Thursday and hopefully be able to provide 
              a quick fix.   The radiometer system does appear to be 
              reading out correct values, so I can provide a report 
              on if liquid is being detected by the system.  No other 
              major glitches to report..... John
