Rain and Thunderstorms possible this evening

The cold front forecast to slide through the valley this evening looks a little beefier than first thought. The valley could see scattered showers and a few thunderstorms as it passes through between 7 and midnight.
The key to this improved chance for rain and thunderstorms comes from the upper level winds flowing over the valley helping to create greater lift and that means heavier rain and stronger storms are possible.
Timing is everything; the front needs to slip south as near to sunset as possible in order to benefit from the daytime warmth. The closer it passes to midnight the weaker the chance for rain and storms.
Temperatures behind the front are forecast to be a tad cooler as well. High will be in the upper 70's Wednesday with clearing skies and north winds 10-15mph.
