Warm layer max T and depth – both events combined (from the RUC analysis)
Notes:
The data on this slide shows the relationship between observed precipitation type, and RUC analysis warm layer maximum temperature and depth, at Scranton (AVP), Binghamton (BGM) and Syracuse (SYR) for both events combined. Rain appeared to occur with maximum warm layer temperatures of 6 degrees C or more, and warm layer depths of greater than 175 mb. Freezing rain occurred with maximum warm layer temperatures between 3 and 6 degrees, and warm layer depths from 100 to 175 mb. A mix of freezing rain and sleet occurred with maximum temperatures between 1 and 3 degrees C, and warm layer depths of 60 to 120 mb. Sleet or mixed sleet and snow occurred with maximum warm layer temperatures ranging from -3 to -3, and small or no warm layer depth. Note that one sleet observation occurred with a maximum temperature of -3 degrees C. A discussion on how that may have been possible is given on slide 13.
