Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 351 PM EDT Sat Jul 05 2014 Valid 00Z Sun Jul 06 2014 - 00Z Tue Jul 08 2014 ...Heavy rainfall from Arthur has ended, but some gusty winds remain in its wake across the Northeastern U.S.... ...There is a slight risk for severe weather across the Midwestern U.S. on Sunday... ...Active monsoonal convection is expected across the Southwest U.S... The extratropical remains of what was Hurricane Arthur continues to move farther away from the U.S. mainland this afternoon bringing an end to the heavy rain across northern Maine. However, some gusty winds remain in place due to the strong pressure gradient associated with the system. South of Arthur, high pressure dominating the eastern part of the nation keeps conditions cool, comfortable, and dry through the forecast period. The exception to this will be across Florida and the southeastern coast as onshore flow and dynamics from a lingering front interact to keep thunderstorms in the forecast over the next few days. Periods of showers and thunderstorms are expected across the northern tier of the country as a slow moving surface front tracks across the Central U.S.. Ahead of the boundary, where surface lifting and instability is best, storms should be more organized in nature which could lead to the threat for severe weather. As a result, the Storm Prediction Center is highlighting a slight risk over parts of the Upper/Middle Mississippi Valley to the Upper Great Lakes on Sunday. By Monday morning, the showers and thunderstorms should begin moving into the Ohio Valley and Lower Great Lakes. Across the southwest, monsoonal flow off the tropical Pacific Ocean will continue to fire up mainly widespread convection across the Four Corners region through the remainder of the weekend and into next week. As usual, the best coverage of storms should occur during the afternoon hours when diurnal heating is at its peak. Monarski Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_wbg.php
