Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 344 PM EDT Thu Jul 09 2020 Valid 00Z Fri Jul 10 2020 - 00Z Sun Jul 12 2020 ...Low pressure moving up the East coast will bring rain, wind, and high surf to parts of the Mid-Atlantic and Southern New England Friday into Saturday... ...Enhanced risk for severe thunderstorms across the Northern Plains on Friday... ...Hot, potentially record breaking, temperatures expand across much of the Southern states as well as parts of the Lower Great Lakes... A low pressure system off the coast of North Carolina is currently being monitored by the National Hurricane Center for tropical development. Regardless of development/classification though, impacts from this system will extend across the Mid-Atlantic into Southern New England including moderate to locally heavy rainfall and flash flood potential near and north of its track, gusty winds, and rough surf along the coast. Please refer to the NHC for the latest on this system. In the north-central U.S., one frontal system shifting across the Upper Midwest states today will continue to bring showers and thunderstorms to this region. Both WPC and SPC highlight the potential for flash flooding and strong to severe thunderstorms through tonight. Expect showers and storms to move into the Ohio Valley and Southern states tomorrow associated with this system. A second frontal boundary should eject out of the Rockies on Friday, into a warm and juicy airmass. Showers and storms will develop along and ahead of the system. SPC highlights a slight to enhanced risk for severe weather tomorrow afternoon and evening across much of the Northern Plains. Moderate to locally heavy rainfall may also accompany any developing storms. Expansive upper level ridging will keep hot and above normal temperatures in place across much of the South. Temperatures over western Texas and eastern New Mexico may approach records for at least the next two days (and likely beyond). The Desert Southwest will be hotter still, with afternoon temperatures soaring into the 110s each afternoon. Above normal temperatures across Southern Florida may also be near record values in a few locations. Above to much above normal temperatures are also expected to expand into the lower Great Lakes and interior New England as well. Heat advisories are in effect across much of the Southern High Plains/Texas as well as the lower Great Lakes, with excessive heat warnings spanning the Desert Southwest.
