GA and test pilots in AWDE engaged in discussion on the experimental AWT products.

Day Three in the Testbed

Participants in AWDE collaborate with AWT via NWS Chat and a live video feed

Participation from a research meteorologist and TFM subject matter expert led to a collaborative discussion with AWT on the CAWS products that were issued throughout the day with CCFP overlays. Participants also offered feedback on the experimental long-range and TAF products.

Day Two in the Testbed

Tuesday in the AWDE CPAC included participants with TFM backgrounds as well as GA pilots. Feedback was given on the long range experimental products, C&V and TAF products, as well as CAWS and new versions of the CCFP.

2016 AWT Summer Experiment is Underway

The Aviation Weather Testbed's 2016 Summer Experiment started this week with participants from across the county. This summer's experiment includes a test of cloud and visibility grid collaboration, new AWIPS2 convective SIGMET production tools, and experimental guidance including new versions of the CCFP.

Experimental CAWS 004 issued for low turb over southern CA

Collaborative Aviation Weather Statement 004
NWS Aviation Weather Center Kansas City MO
1919 UTC Mon 22 Feb 2016

Weather: Turbulence
Valid: 1919-0100Z

ARTCCs affected: ZLA
Terminals affected: KLAX, KPHX

SUMMARY: Moderate to severe turbulence expected over S CA thru 23Z

DISCUSSION: Moderate to severe turbulence with isolated severe pockets are expected over S ZLA thru 01Z. NE flow will contribute to a moderate Santa Ana wind event with low level turb expected below FL100.

A SIGMET is unlikely at this point, an additional CAWS is also unlikely.

Valid: 1800-2000Z

ARTCCs affected: ZAU, ZMP, ZOB
Terminals affected: KDTW, KMKE, KMDW, KORD

SUMMARY: Possible SEV icing over Great Lakes.

DISCUSSION: Moderate to occasional severe icing is expected over the Great Lakes with highest potential for severe from eastern WI, northern IL, and western Lower MI. This may impact arrivals/departures for KDTW, KMKE, KMDW, and KORD. A SIGMET is possible in the hatched area. Conditions will slowly shift east-northeastward into central lower MI and weaken after 20Z.

Moderate turbulence is most likely from FL360-270 with severe possible from FL340-290. Conditions are moving eastward and are likely to continue over the Mid-Atlantic coastline after 20Z.

...Additional CAWS are likely in this region...
