A WET START...

Check out the sharp trough of Low Pressure over the western half of the states. This feature will be quite the rain maker for us. Moisture is streaming in off the Pacific and as the system moves eastward, it will tap into the Gulf. Some of the jetstream energy plowing into the west coast of Canada will choose the path of least resistance, continuing on an easterly track across the northern tier of the states. This will slow the movement of the trough and allow several disturbances to train through our area.

By Monday evening, the first in a series of waves of low pressure, promises to develop showers and thunderstorms across our entire area. Initially, isolated cells have the potential to be severe, producing large hail, gusty winds and perhaps an isolated tornado. The greatest tornadic threat looks to remain just to our south, though we'll be watching all storms closely for this possibility at the onset of the event. A some-what stationary frontal boundary within the jetstream flow will channel disturbances over the same area through Tuesday night, producing flooding rain. Some model data suggests three inch totals, by Wednesday morning and amounts much higher are possible. As with any heavy rain event, please use caution while traveling and do not try to cross flooded creeks, streams, or roads. Just a foot and a half of swiftly moving water can displace your car, SUV or truck, floating it away like a boat without oars, a propeller or rudder!
