Use of Lightning Climatologies in GFE
Radar ClimatologiesHigh resolution historical database of gage/radar precipitation for the state of Florida and southern GeorgiaParticipants: The Florida Department of Environmental Protection (FDEP); Prof. Henry Fuelberg (FSU Department of Meteorology); WFO Tallahassee, Southeast River Forecast Center (SERFC), NWS Hydrology Laboratory; and U.S. Geological Survey - FL. Currently 4 years of WSR-88D data for SE U.S.

Coastal Waters Temperatures
• Air temperatures over water – new weather element
• Forecasters were not familiar with this
• Training had to be done to introduce forecasters
• Start with climatologiesData readily available from NDBC Data goes back many years at some buoys
