Live Blog – 9 June 2009 (2:36 pm) – IOP start

Alrighty…

We left the debrief to start LMA training and then right into a LMA IOP over the DC LMA.  We were paid a visit by OS&T chief Don Berchoff

We then did some CASA training until things startewd initiating in DDC, ICT and OUN CWAs.  The southern most storms (OUN CWA) struggled against the cap so we opted against a PAR IOP and stuck with a MRMS IOP for DDC and ICT.

We had problems with the AWIPS server (load issues) but eventually got going.  Unfortunately, it was too late to capture the tornado E of the KDDC radar that V2 was on.

As of 0035z (10 June), we are relocalizing from DDC to TSA as storms enter Osage Co.  OK.

Outlook – 9 June 2009

Welcome to the MDT risk.  Today we are looking at two plays/IOPs today.  We’ll start off the day with LMA training and slide right into an LMA IOP over the DC domain.  We’ll break and re-evaluate with the initial idea of operating a MRMS IOP over the MDT risk along S KS.  However, we will switch to a CASA/PAR realtime IOP *if* significant storms develop in/near the CASA domain.

Looks like things are heating up…

Summary – 8 June 2009

Greg is stepping through the replay of tonight’s event comparing the HWT warnings with the NWS warnings.

First impressions with MRMS from the forecasters:

Bill – took a while to get used to MRMS data

All- liked the trending info

Daniel N. – interested in combining base data with MRMS data in a 4-panel.  Also found track info helpful in polygon issuance

Steve – MRMS data helpful particularly when storms went near/over radar.  Expressed concern about the difference between MRMS “X above Y” compared to single radar data and model soundings.  Found Rotationtracks quite usedul.

Discussion – usefulness of “X above Y” products when dual-pol comes along.  Will these become obsolete?  All agreed that this would be very useful in reanalysis

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)

Live Blog – 8 June 2009 (3:27 pm) – Week 6 Preview

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”.

Outlook – 8 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.)
