After a nice thaw over the weekend temperatures will be retreating back below zero for lows again. Gusty northwest winds are bringing down more cold air from the arctic today. Temperatures tonight will drop below zero in the northern half of the state where snowpack still reigns while the rest of the state will see single digits lows. The same will be said for Wednesday morning as well, with more lows in the single digits above and below zero. Highs on Tuesday and Wednesday will be in the teens and 20s, with maybe a 30 in areas with no snow on the ground. Temperatures will rebound nicely later this week with highs possibly heading back above 40 again. So if nobody washed their vehicles this past weekend, there is ample time later this week into next weekend where you can do it.
