We had a good discussion regarding last night’s events.  We started off with reviewing the GOES-R verification from CIMSS, actually for operations on the 7th and then the 8th.  We then moved to the MRMS review which prompted a good discussion on the use of divergence fields – particularly storm top divergence.  Chris showed a satellite div/vort field that is being jointly developed by CIMSS and NSSL via Bob Rabin.

As for today’s operations: We had hoped that we could perform realtime pGLM analyses using the NAL domain.  Early convection had suppressed that hope (excuse the pun) momentarily, but as the day continues, new/re development appears to be likely in the OHX/HUN areas which is advantageous to pGLM ops.

We begin our first full day with a debrief/discussion from last night’s activities.  Dan D., Frank A., Pat S. Andy T. and Dan N. led off with a good discussion focusing on some of the merged grids as well as some discussion on polygon orientation.  The participants provided several good suggestions for products and product improvement.

We followed up with a discussion on today’s activities.  SPC has outlined a focused area in E KS, and we will plan out operations there.  We were hoping to get a good look at the GOES-R products, but there is considerable cirrus limiting the usability of that product in that area.  We have cheated out floater domain to provide some overlap to the W where the cirrus are less, and as I type, the UWCI product is lighting up over the TX PH. Also, a TOR watch has been issued for E KS.

Frank and Pat are running through an archive case for GOES-R / pGLM / LMA, while Dan, Dan and Andy are taking a look at the realtime GOES-R products.

We may take a 30 minute dinner break -or- start into MRMS/GOES-R ops (and do dinner in shifts) immediately after the archive case since we are expecting early initiation.

Today we start week 8 of the 2010 EWP.  Our visitors are Frank Alsheimer (WFO Charleston, SC), Dan Darbe (WFO Atlanta/Peachtree City, GA), Daniel Nietfeld (WFO Omaha, NE), Pat Spoden (WFO Paducah, KY), and Andy Taylor (Norman, OK).

We will start with training the forecasters on the new products they will see.  Training will start with GOES-R products (CI & Overshooting Tops-Thermal Couplet), followed immediately by LMA/GLM training.  We will take a break an then do MRMS training likely followed by observing realtime products to get the forecasters used to looking at the data.

Regarding today’s outlook.  There is a large slight risk area across the Central & High Plains stretching west across the WY/CO border and terminating in the northern half of Utah.

There is not strong confidence in getting much in the way of SVR in the OK domain today (the best chance of SVR among all the possible domains).  We will likely run our Introductory IOP in our Floater Domain and likely set that near NE CO/SW NE / SE WY where there is currently an MD as this entry is being typed.
