The warm weather that swept into Louisville this weekend will remain for the rest of the week, and possibly longer.National Weather Service Meteorologist Brian Schoettmer says it's unlikely any more blasts of northern arctic air will hit the region anytime soon. He says as long as the skies remain relatively clear, high temperatures will stay in the 50s and 60s through the weekend."This is the time of year when the sun angle actually starts to get higher in the sky and we actually get more efficient heating early in the day. Basically, the time is right for temperatures to really start increasing," he says. "We forecast just seven days out, so in the near future, it's not going to get arctic cold. You can get lows into the mid to upper 30s each night. We're not expecting a return to the winter-like conditions this week."
