Model Diagnostic Discussion NWS Weather Prediction Center College Park MD 147 AM EDT Fri Aug 24 2018 Valid Aug 24/0000 UTC thru Aug 27/1200 UTC ...See NOUS42 KWNO (ADMNFD) for the status of the upper air ingest... 00Z Model Evaluation...with Preferences and Confidence ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ...Overall Synoptic Pattern across the CONUS... ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Preference: General model blend Confidence: Average For most of the larger scale systems, the 00z deterministic models and 12z ECMWF are in generally good agreement -- supporting the use of a general model compromise for most systems. The primary exception is the upper trough over the northern-central Rockies and High Plains Sun-Mon. The 12z ECMWF is the most significant outlier here -- showing a more progressive trough moving from the northern Rockies into the High Plains Mon morning. Consensus of the 00z deterministic models and the GEFS Mean is slower, with the trough axis much further west back across the northern Rockies Mon morning.
