(This evening through Wednesday Night) Unseasonably warm and quiet weather will continue into mid-week and beyond as ridging maintains its presence at the sfc and aloft. Consequently, some patchy fog will be possible mainly in southern zones overnight as the warmer Gulf air begins to overspread the relatively cooler sfc with low clouds also making a gradual return northward. Overnight low temperatures will generally range from the mid and upper 40s north to the lower and mid 50s south where cloud cover is likely to be more prevalent closer to daybreak. Despite the returning cloud cover on Wednesday, southerly flow will fuel the continued warm air advection as high temperatures should settle very near today's maximums in the upper end of the 70s with ridging aloft centered across the south central CONUS.
Temperatures are quickly climbing so had to make some adjustments to the diurnal trend, with forecast highs now a degree or so warmer in places.
