Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 358 PM EDT Wed Aug 30 2017 Valid 00Z Thu Aug 31 2017 - 00Z Sat Sep 02 2017 ...Tropical Storm Harvey will spread heavy rain from parts of the Lower Mississippi Valley and parts of the Ohio/Tennessee Valleys... ...There is a slight risk of severe weather over parts of the Central Gulf Coast... ...Heavy rain possible over parts of the Southern/Central Appalachians... Tropical Storm Harvey is currently making another landfall early this morning across southwestern Louisiana before weakening to a tropical depression later in the day. Fortunately the circulation and its moisture pool have moved east of Houston, Texas, thus allowing the region to finally dry out. The intense heavy rainfall has moved eastward toward Beaumont, Texas which has seen almost 18 inches of rain in a 12-hour period ending at 1 AM CDT. While hourly rainfall rates of 2 to 3 inches may be possible as Harvey lifts northward, the forward progression should help diminish the duration of the event. The current forecast paints a broad area of 3 to 6 inches of rainfall the next couple of days from southwestern Louisiana up along the Arkansas/Mississippi border and into western Tennessee/Kentucky. Of course embedded higher amounts are possible where some of the more intense bands of rainfall congregate. As such, a flash flood risk will remain for locations northward into the western Tennessee/Ohio river valleys. Additionally, a risk for some severe weather, perhaps a few tornadoes and damaging winds will be possible over southern Mississippi as Harvey migrates inland. Elsewhere, light to moderate rainfall should come to an end over areas of southern coastal New England. Conditions are expected to remain on the cooler end for late August/early September with forecast highs generally 5 to 10 degrees below climatology from the Mississippi River eastward. The cool spot will be across the Great Lakes and interior northeastern states as highs stay in the 60s with a strong cold front sweeping through.
