The tens of thousands of Iowans heading out to take part in tonight’s caucuses will need to don their warmest winter coats, hats, gloves and scarves. National Weather Service meteorologist Brad Small says it’ll be very cold at 6:30 this evening as the key political meetings are scheduled to get underway statewide. Temperatures should be in the single digits to lower teens with wind chills in the single-digits and close to zero. Small says the weather service is -not- predicting snow tonight.No precipitation is expected, it’ll just be cloudy and cold.
