We've got not 1, not 2, but 3 (maybe even 4) cold fronts on the map for this week that promise to bring us the coldest air so far this season.
The only exception is Monday when we will reach low 70s for highs.
This morning we had frost in many outlying areas (see picture from Lebanon), and we could see a whole lot more of that, and maybe even a freeze later this week.
The first front should cool us down from Monday's low 70s to the mid 60s on Tuesday.
The next two fronts will bring even colder air by Wednesday, and Friday respectively.
Behind them, we should see 50s for highs and low to mid 30s for lows, with many outlying areas possibly seeing a freeze.
That possible 4th front could be here by Sunday or Monday of the following week and be even colder!
