Anchorage’s increasingly snow-dusted mountain peaks and noticeably cooler nights have foreshadowed the inevitable: winter is nearly here. Anyone who has denied the evidence while entertaining the notion we have weeks to go before the first flakes better grab the down jacket. The National Weather Service is predicting temperatures in the low 30s for Wednesday night, bringing with them the possibility of rain and snow on the Hillside. The good news, if hanging onto the last sunny days of fall is your objective: No accumulation is expected. The bad news: Five of the next seven days in the week-long forecast mention a chance of snow.
