Long-range Coffman & Valentino
The main feature in this next week will be the high pressure system from the North settling in the area. We'll start feeling those temperatures drop Monday morning reaching single digits in most of the state by the end of the day.
Monday evening into Tuesday morning we'll be seeing our coldest temperatures this week, especially in the northern part of the state. Temperatures could reach from -15C to -24C (5 to -10 F) throughout the state.
The strong winds starting Monday from the incoming system will slow down late Tuesday/early Wednesday where the high pressure system settles on top of Indiana which will affect the rest of the week.
Average virtual temperature of the 1000-500mb layer gives 248K...-13 F!!!
