00 hr RUC frontogenesis and lapse rate valid 1/18 12z
Notes:
0 to 5 hour RUC forecasts of 700-500 mb frontogenesis and lapse rates valid from 06z through 14z are shown in the next few slides. Note that the frontogenesis band initially moving east across central Pennsylvania was forecast to intensify, then slow down over eastern Pennsylvania and southeast New York. Lapse rates along and west of the band were forecast to remain around 4 to 6 degrees C per km through the event. Click on the image for a larger view.
