A nearly stationary boundary remains stalled across the region this Friday but will drop to the south later today and tonight in response to a shortwave digging in from the west. Additionally, a broad area of low pressure with tropical origins is forecast to track up the east coast and pull even more tropical moisture our way. The net result of these two weather features on our weather locally will be heavy rain and storms today and into the overnight. Weather guidance suggests that a large portion of the region could pick up over an inch of precipitation with higher amounts up to two and half inches possible mainly south and east of town. Furthermore, atmospheric conditions today and even into the overnight will be unstable enough to support a few severe storms capable of producing strong damaging winds and heavy downpours. In anticipation of this heavy rain falling within a short period of time the National Weather Service has placed nearly all of the region under a Flash Flood Watch from Noon today until late tonight.

A few showers may linger into the early hours Saturday before departing and gradual clearing takes place. Even with some early morning clouds and showers we should still make it to near 90 degrees by the afternoon.

High pressure will build into place for the second half of the weekend and into Monday before another cold front heads out way Tuesday.
