About Slew

Snohomish Slew, a frognosticating bullfrog, makes an annual Groundfrog Day weather forecast for the Pacific Northwest in downtown Snohomish. There is much accompanying pomp and ceremony. From Thayer Cueter, Slew’s handler: “The pinnacle celebration moment [is] when Slew whispers his frogcast to his favourite scribe in Groundfrogese. [The] gathered crowd will be ribbeted! by every transcribed word from Slew as he accurately predicts our winter weather fate for six more weeks.”
