Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 400 AM EDT Tue Jun 03 2025 Valid 12Z Tue Jun 03 2025 - 12Z Thu Jun 05 2025 ...Widespread heavy rain and severe weather threats across the mid-section of the nation today will gradually shift eastward and lose intensity over the next couple of days... ...Tropical moisture across South Florida is forecast to spread further up the Florida Peninsula and into the coastal Southeast... ...Renewed round of showers and thunderstorms expected to move across the Four Corners into the central/southern High Plains... ...Much cooler weather settles into the Central U.S., while the East warms up... The widespread active and severe weather currently affecting the mid-section of the country is forecast to lose some intensity as the associated frontal system gradually weakens with time. The front is still quite potent this morning as it forces its way down the central Plains and interacts with moisture associated with a lifting upper-level trough. The heaviest rain and most potent thunderstorms will be impacting much of the central Plains this morning. As the last in a series of low pressure waves traveling along the front heads further northeast later today, thunderstorms are expected to organize farther to the east and southeast from Oklahoma through Missouri into Illinois by tonight, where high winds and large hail will be the greatest severe weather threat here, with a lesser threat of tornadoes. By Wednesday, the front is forecast to weaken as it pushes farther to the east during the next couple of days. The associated showers and thunderstorms are expected to be much less intense and more scattered as they move across the Great Lakes and the Ohio Valley later on Wednesday into Thursday morning. Another upper trough currently dipping off the coast of California will bring a renewed round of showers and thunderstorms for the Four Corners into the central/southern High Plains from Wednesday into Thursday, raising flash flooding chances over areas with terrain-enhanced rainfall and burn scars in the aforementioned areas. Meanwhile, tropical moisture that has already brought heavy rain across South Florida in the vicinity of a stalled front will continue to interact with an upper-level trough moving into the northeastern Gulf. This interaction will lift the core of the tropical moisture northward, leading to the threat of heavy rain spreading up the Florida Peninsula today and into Wednesday morning when localized flooding is possible, especially across urbanized areas. This rain episode will be much welcomed as this region remains in severe to extreme drought conditions. The National Hurricane Center is monitoring the possibility for this system to organize and develop subtropical or tropical characteristics off the coast of the Southeast U.S. through the next couple of days. While temperatures cool across the mid-section of the country, the opposite will occur along the East coast. The recent prolonged period of below average temperatures will be replaced by an increasing area of above average temperatures from the mid- to lower Mississippi Valley, east into nearly all of the eastern U.S. as an upper-level ridge builds across these regions. The exception to the above average temperatures in the East will be across Florida and the coastal Southeast where temperatures will be below average due to the presence of tropical moisture under the upper-level low.
