The dry and mild winter has finally ended but the warmth continued well into March.  We have seen much cooler air over the past two days and that could lead to some patchy frost early Wednesday as overnight lows dip into the 30s.  The chilly will be brief as much warmer air arrives by Wednesday afternoon.  Highs will reach the 70s on most days through the end of the week and we should see a decent amount of sunshine.  There  will be a slight risk of a shower early Thursday then a better chance for a few showers and thunderstorms on Saturday.  Overall, it looks like a nice spring pattern will develop into April.  We could still see some frost in April but I don't see any major issues for the next week after tonight's chill is over.
