Forecaster comments from EWP blog...
The synthetic WRF run at 05082012 at 0Z correctly predicted several
upper level features and mesoscales features correctly for the afternoon
of 05082012. The following 4 images show synthetic WRF images of IR
(upper left), WV (upper right), and 10.35u-12.3u IR Band Difference
(lower left). Looking at the WV imagery you can see an upper low over
the U.S. Southwest as well as an upper trough over the upper Midwest.
In the IR and WV imagery you can see convection occurring from AZ to NM
to TX to CO to Old Mexico. In the brighter white areas of IR, you can
see low level cloud cover. In the Band Difference image, you can see
the area of best moisture and “hot spot” for convective initiation in
the southern tip of TX and into Mexico. The 5th image below is the true
observed IR (upper left) and WV (upper right) which verifies the
synthetic WRF. This imagery would be very helpful to forecasters in the field
because it seems to do a decent job of predicting upper level features,
low level clouds, and convection 12-20 hrs in advance.
