Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 202 PM EDT Thu Apr 10 2025 Valid 00Z Fri Apr 11 2025 - 00Z Sun Apr 13 2025 ...Stormy weather from the Mid-Atlantic into New England, with late season accumulating snows possible in the higher elevations from northeast Pennsylvania into eastern New York and central to northern New England... ...Severe thunderstorms possible Thursday evening/night from the Lower Ohio Valley into the Tennessee Valley, Lower Mississippi Valley and South... ...Record warmth expected Friday from the Southwest into the Great Basin and Saturday from the Southwest into the Central to Southern High Plains, while cooler temps push into the Pacific Northwest and Northern Rockies Friday and Saturday... ...An elevated fire weather risk across portions of the Central to Northern Plains and Central Florida... The mid to upper level flow continues to amplify across the CONUS, leading to an active weather pattern across large portions of the eastern third of the nation. The eastern component of this amplifying flow will be comprised of an deepening upper trof from the Great Lakes into the Southeast. The associated area of surface low pressure forecast to move slowly northeast from the Southern Appalachians and off the Mid-Atlantic coast Friday and Saturday will bring increasingly stormy weather from the Mid-Atlantic into New England over the next 48 hours. Some much needed moderate to heavy rains are possible from the Mid-Atlantic into southern New England where widespread moderate to severe drought conditions exist. Late season accumulating snows also possible with this system in the higher elevations from far northeast Pennsylvania, across northwest New Jersey, northern and eastern New York State, and western, central and northern New England. Severe thunderstorms are possible along the trailing cold front pressing southeastward Thursday evening into Thursday night across the Lower Ohio Valley, Tennessee Valley and into the Lower Mississippi Valley and South. The greatest risk for severe weather across these regions will be from high winds and large hail, with a lesser threat of tornadoes. While the overall amplified flow across the CONUS is leading to stormy weather across large portions of the east, the western component of this amplified pattern will support much above average to record warmth across large portions of the western and central U.S. Record high temperatures are possible Friday from the Southwest into the Great Basin and across the Southwest into the Central to Southern High Plains on Saturday. Some cooling to the widespread much above average western temperatures set for the Pacific Northwest into the Northern Rockies where high temperatures are forecast to fall to slightly below average Friday and Saturday in the wake of a cold front pushing off the northeast Pacific and inland across the Northwest. Warm temperatures, low relative humidities and windy conditions expected to spread into the Central to Northern Plains over the next two days. This will increase the risk of wild fires across these areas. Red Flag warnings are currently in effect across much of South Dakota, Nebraska into northwest Kansas, affecting approximately 2 million people. Winds are also expected to strengthen Saturday across Florida in the wake of the above mentioned cold front sinking southeast. These increasingly windy conditions and lowering relative humidities will also increase the fire weather risk for central Florida on Saturday.
