Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 358 PM EDT Sun May 13 2018 Valid 00Z Mon May 14 2018 - 00Z Wed May 16 2018 ...There is a slight risk of severe thunderstorms over parts of the Mid-Atlantic, Ohio Valley, and Southern Plains... ...Heavy rain possible from parts of the Northern Ohio Valley into the Central Appalachians... ...Heavy rain possible over the east coast of the Florida Peninsula... A quasi-stationary front extending from the Mid-Atlantic westward to the Middle Mississippi Valley then southward over the Southern Plains will aid in focusing showers and thunderstorms from the Mid-Atlantic westward to the Central Plains through Tuesday. In addition, diurnally driven showers and thunderstorms will develop along and ahead of the associated dryline through Tuesday, too. Additionally, a deep upper-level low over the Great Basin will slowly weaken through Tuesday evening. The energy associated with the low will aid in producing showers and thunderstorms over parts of the Northern/Central Plains, Northern Intermountain Region, Great Basin, and the Sierras likewise through Tuesday. Meanwhile, a developing upper-level low over the Northeast portion of the Gulf of Mexico will aid in drawing a plume of moisture from the tropics over Florida moving northward into the Southeast and into the Central Gulf Coast by Tuesday. The moisture will aid in developing showers and thunderstorms over Florida that will slowly move northward into the Southeast and into the Central Gulf Coast by Tuesday evening.
