.DISCUSSION...
A strong cold front will push through the region tonight, triggering
numerous showers and thunderstorms, some of which are likely to
become severe. A secondary cold front will cross the area by mid-
week before high pressure gradually builds in from the northwest by
Friday. This leads to a period of below normal temperatures and low
humidity.
