Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 414 PM EDT Wed Jul 11 2018 Valid 00Z Thu Jul 12 2018 - 00Z Sat Jul 14 2018 ...Hurricane Chris will continue to track northeast over the Atlantic Ocean... ...Severe thunderstorms expected across portions of the Northern Plains and Upper Mississippi Valley through Thursday... ...Heavy rainfall and flash flooding possible across portions of the Southwest and southern Rockies... Hurricane Chris is expected to pick up the pace and track further northeast out over the Atlantic Ocean, while transitioning to a post-tropical system. As it continues to shift away from the coast, impacts will lessen along the coastline this evening and through the overnight. Heavy rains may still be possible, however, across portions of the Mid and Southern Atlantic coast through the end of the week. For the most current information regarding Chris, visit the National Hurricane Center (www.hurricanes.gov) and the local forecast office for individual watches/warnings/advisories. A strong cold front will continue to slowly shift eastward across the north-central U.S., resulting in the risk of severe weather across portions of the Northern Plains and Upper Mississippi Valley tonight through Thursday. This will couple with a very moist atmosphere and may also result in excessive rainfall and flash flooding concerns for portions of this region through tonight. Excessive rain concerns may also continue into the day Thursday for portions of the Northern Plains. Convergence of showers and thunderstorms will increase across the Southwest and into the southern Rockies to end out the work week as monsoonal moisture surges north. Heavy rainfall along the terrain could lead to flash flooding, with a magnified threat in flood prone areas. Because of this, there is a slight risk of flash flooding in the Southwest and southern Rockies from now through Friday. Wix Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
