Rebooted the px1 server about 45 minutes ago due to load issues. Each team had to restart their WeatherCase Browsers to allow the notification to work properly.
Storms have generally moved out of the GRR CWA (though some echoes remain) and into the DTX CWA. Warnings for DTX continue.
Gail Hartfield has just joined us and we threw her into the WDSSIIB team (DTX) since they are the most active.
We’ll wrap up in about 30 minutes.

DTX feed went down from abour 2223z to 2250z. This affected WDSSIIB (Steve/Bill), though they didn’ catch it immediately since the MRMS data continued to update. DTX has since returned.
WDSSII (Daniel/Dan) are trying a 4-panel setup with “All-Tilts” REF, “All-Tilts” VEL, MESH and another MRMS product. They also inquired about the biased corrected MESH.
Steve just noticed that the MESHB values he is looking at is lower than the regular MESH. (less than half inch)

Greg is showing some of the MRMS products on the AWIPS display to the forecasters. We are going to run an IOP for Michigan. We have sectorized to GRR and DTX.
Daniel (N.) and Dan (M.) are running the WDSSIIA over GRR and Bill and Steve are the WDSSIIB team (DTX).
We are analyzing as of 2220z.

This is the last week of the HWT. Forecasters are:
Bill Ward (HNL), Daniel Nietfeld (OAX), Gail Hartfield (RAH), Steve Keighton (RNK), and Dan Miller (DLH)
Gail had a delayed flight and will be arriving into OKC around 6 pm.
The overall weather outlook this week has a stalled front drapped across OK. This should provide good potential for the Central OK observing platforms (PAR/CASA/LMA). We will examine the potential for severe weather outside of C OK for MRMS simply to avoid being too “Okla-centric”.
Kevin Manross (EWP Weekly Coordinator, 8-12 June 2009)
There is a shortwave trough entering the Great Lakes region from the west. Additionally, there is a broad jet streaming from the SW US to the upper MS valley. At the surface, there is a cold front extending from the SW Great Lakes area SW through OK and into the southern TX PH.
There appear to be three potential plays today. 1) NE CO (DCV), 2) SW OK into the Abilene, TX area, and 3) the Southern Great Lakes area. Area #2 has greatest potential for (large) hail, and area #3 appears to have greatest tornado potential.
Forecasters are going through their training on WDSSII as well as PAR and MRMS. We will break at 4 pm and evaluate whethar to begin and IOP (and for which area), or to try and sneak in CASA training. (LMA training will wait until tomorrow.)

End of IOP. Storms in the RAH CWA are rapidly trending down and leaving the CWA. Since we started before 4 this afternoon, we’ll call it a day. Discussion follows…
Used the MESH and RotationTracks for intensity trends more than location. Storms today didn’t really deviate much. Tracks helped to narrow warning areas. There was some question regarding the usability of the Lightning forecast products in their current form. Color table may need to be adjusted.
Scott – liked trends a lot. Found them to be quite useful and informative.
Gino :: trends seem “black boxish” right now, so confidence is low. Relies more on based data. Worried about false peeks and whether to trust the intensity diagnostic. Good SA tool and for “post analysis”. Likes Reflectivity at -20C
Suggestion :: VIL (or a Reflectivity sum product) above -20.
Slider capability for product values, similar to how we adjust isosurfaces.
Products in GoogleEarth were very popular. Most agreed that they would be useful in SA.
Trends were helpful in discriminating between “similar” looking storms. Trends were also useful in warning decision making.
Kevin Manross (EWP IT Coordinator)
Talking with Tom (WDSSIIB) for a moment. Due to the technical difficulties that we’ve been having (and may be stabilized for the time being), Tom is just now starting to use the MRMS gridded info. He has been looking at the RotationTracks, MESH, and Reflectivity at -20C.
Kevin Manross (EWP IT Coordinator)
Both teams (WDSSIIA :: Gino/Jeff & WDSSIIB :: Tom/Scott) have been issuing warnings despite the MRMS grids not auto-updating in AWIPS. They have relied on base data analysis, along with suplementing MRMS grids/trends via GoogleEarth.
We are still focusing on RAH, with storms entering an ubstable environment fromthe west of the CWA. Greg is troubleshooting the notification of the MRMS grids in AWIPS.
Kevin Manross (EWP IT Coordinator)
Finally! We got everything up and running for an IOP in the RAH area. We have two teams operating in the same CWA.
WDSSIIA :: Gino and Jeff
WDSSIIB :: Tom and Scott

Dave and Ryan have updated their storms. For their southern storm, hey have two cells encompassed by one threat area. An issue they struggled with in this approach is that they felt that the differing updrafts had different probabilities.
Dave said that it is tough to track so many updrafts, even if he was more comfortable with the software.
Dave and Ryan have traded off at 0037z – Ryan is now drawing polygons.
