Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 327 AM EDT Sat Jul 10 2021 Valid 12Z Sat Jul 10 2021 - 12Z Mon Jul 12 2021 ...Flooding and strong storms expected for portions of the Midwest and Central Plains... ...Heat wave continues for much of the western U.S. this weekend... Now that Tropical Storm Elsa has exited the Northeast U.S., a more pleasant weather pattern is expected across much of the Mid-Atlantic and extending northward to New England on Saturday with a cold front exiting the East Coast and a slightly cooler/drier airmass settling in, with perhaps some lingering showers near the coast on Saturday. However, heavy rainfall will be making weather headlines across much of the Midwest and portions of the Ohio Valley this weekend. A slow moving frontal boundary is expected to exist between the central Appalachians and central Plains through Sunday morning before lifting northward as a warm front. A well defined upper level trough will support the development of an organized surface low across the Midwest, and this will aid in the development of multiple mesoscale convective systems that could repeatedly affect the same general areas, particularly from Missouri to central Kentucky where several inches of rainfall will be possible along with numerous strong to severe storms. In addition, the Storm Prediction Center has an Enhanced Risk of severe storms across portions of Oklahoma, Missouri, and Arkansas for Saturday. In the temperature department, excessive heat will continue across much of the Western U.S. as daytime highs soar well above normal with highs well into the 90s for much of the Great Basin and widespread 100+ degree readings for valley locations. Numerous daily high temperature records could be in jeopardy of being broken, particularly for California and Nevada. Highs could approach 115-120 degrees for the lower elevations of Arizona and eastern California this weekend! For parts of the Great Basin and Northern/Central Rockies, the combined hot and dry conditions may lead to an elevated risk for fire weather through Sunday, particularly where Red Flag Warnings remain in effect between northern California and Wyoming. Meanwhile, temperatures will be comfortable for this time of year from the Dakotas to the Midwest this weekend. Hamrick Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
