Model depiction of cold and wet conditions over the Southern High Plains.

NWS meteorologists make forecast decisions based on model data like the graphic shown at the left. Forecast models use upper air and surface data, satellite imagery, and other data which are fed into computers which use complex atmospheric equations to project how the atmosphere may change over the next several days.

New model data, via high speed satellite transmission is generally received twice per day. Confidence in the model guidance is based on the forecasters expertise and experience on how well a particular models handling the meteorological situation. Confidence increases when the models are consistent from run to run.

In this case, the model indicates breezy winds from the northeast combined with relative humidity between 80-90 percent along with temperatures cold enough for snow fall. The model worked well in this case!

...WFO Amarillo bids farewell to Jim Wingenroth...

Jim Wingenroth had served as an Meteorologist Intern at WFO Amarillo since January of 2002. While Jim was learning to become a forecaster, he worked closely with the Cooperative Observer Program and was very instrumental in several educational outreach programs and projects. Jim was recently promoted to a General Forecaster position at Morehead City, NC. The staff here will miss Jim, but wish him the best in his new assignment.
