.DISCUSSION...
As the front and rain exit the area today a colder air mass will move
in. Lows tonight will be in the 30s to low 40s with areas along and
north of M-20 having the best potential for frost. Wednesday night
will be even colder with most of the area in the low to mid 30s and
spots north of M-20 dropping into the mid to upper 20s. Lows slowly
improve into the 40s for the weekend along with highs around 60
tomorrow warming into the upper 60s to low 70s.
This warm up into the weekend is due to light northerly winds
becoming more southerly ahead of our next chance for rain Monday into
Tuesday. Minimum relative humidity values will largely be in the 30s
and 40s. Central lower has a 20 percent chance for values to drop
into the mid to upper 20s Wednesday afternoon.
