Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 430 AM EDT Thu Apr 10 2014 Valid 12Z Thu Apr 10 2014 - 12Z Sat Apr 12 2014 ...Showers will become increasingly numerous along a cold front crossing the Great Lakes and settling in over the Ohio Valley... Showers will continue to fire up along a cold front pushing out of the Upper Mississippi Valley and crossing the Great Lakes on Thursday. Precipitation will initially stay on the lighter side...but higher totals are expected with this system as the front slows down and settles in over the Ohio Valley and northern Mid-Atlantic states on Friday. A surface wave developing on the boundary...in combination with an increased moisture supply...could really help enhance amounts and pose a threat for flash flooding across a narrow axis stretching from northern Kentucky into northern New Jersey. Thunderstorms will be a possibility within developing precipitation but are not expected to reach severe criteria. Weather will remain fairly quiet across the rest of the Nation over the next few days. A weak piece of energy rippling through the fast flow aloft could trigger a few light showers across the Central to Northern Plains on Thursday and Upper Mississippi Valley on Friday. An upstream system dropping down from western Canada should bring some more widespread precipitation into the northern Rockies and High Plains on Friday...but amounts should stay on the lighter side through at least early Saturday.
