Temperatures will bounce around this week, though confidence is increasing that we’ll end the week with warmer temperatures. The only chance for precipitation this week will be Tuesday across portions of southeast and east-central Missouri and southwest Illinois where there is a 20-30% chance for rain and a wintry mix. Accumulations of snow will be light, a dusting to around 0.2", while a light glaze of ice is possible across isolated areas of southeast Missouri and southwest Illinois.
A warm up could be on the way, confidence is increasing that above normal temperatures are headed our way (normal highs are recorded at our three official climate sites and span from 36°F in Quincy, IL to near 42°F in Columbia and St. Louis, MO). While we could still see normal or even below normal temperatures starting February 9th, there is a 40-50% chance of seeing above normal temperatures between February 9th and 15th. How warm we get and for how long remains to be seen. If above normal temperatures do occur, it will help to melt lingering snowpack across the central US, including any snow that remains in our area.
