Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 402 AM EDT Mon Jun 04 2018 Valid 12Z Mon Jun 04 2018 - 12Z Wed Jun 06 2018 ...Dryer conditions across the Mid-Atlantic today, with showers and thunderstorms moving through the Northeast... ...Severe thunderstorms and locally heavy rainfall possible by Tuesday evening across parts of the northern Plains... ...Well above normal temperatures expected the next few days across the Great Plains and into the Desert Southwest, with below normal values for the Northeast... The low pressure system responsible for prolonged periods of rain and flooding across the Mid-Atlantic the past few days will finally pull away from the coast today. Dryer conditions are expected on Monday, but flooding of area streams and rivers may continue for another couple of days. To the north, an upper level low rotating through the Northeast will bring showers and thunderstorms to the region today with another round of scattered showers and storms across the Mid-Atlantic into the Northeast as a frontal boundary moves through on Tuesday afternoon. The western portion of the boundary is forecast to stall across the Gulf Coast which should keep mainly scattered showers in the forecast the next few days. Return moisture off the Gulf of Mexico into Texas will allow for another couple of days of convection, with a marginal risk for severe weather, as this moisture intersects a dryline and weak frontal boundary. A cold front moving into the northern Rockies this morning will allow for mainly light precipitation along the boundary today. The cold front should reach the northern Plains by Tuesday, and moisture streaming northward across the Great Plains will interact with impulses of upper level energy increasing the chances for showers and thunderstorms across the Dakotas. Thunderstorms may be capable of producing heavy rainfall and severe weather, especially Tuesday evening and early Wednesday morning across North Dakota near a developing surface low. Temperature wise, the Northeast will be cooler than normal under the influence of upper level troughing. Much of the central U.S. and the West will be warm. Afternoon highs in the mid to upper 90s are expected across the Great Plains as well as the desert Southwest, which is about 10 to 20 degrees above normal for this time of the year.
