Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 354 PM EDT Wed May 12 2021 Valid 00Z Thu May 13 2021 - 00Z Sat May 15 2021 ...Showers and thunderstorms to wind down from the Central Gulf Coast to Georgia/Florida on Thursday... ...Below normal temperatures expected east of the Rockies while western third of the country warms up... A frontal boundary that has meandered along the southeastern U.S. for the past few days will finally push off into the Gulf of Mexico tonight, drying out much of the coast behind it beginning tomorrow. However, through tonight, additional showers and thunderstorms are possible across the Gulf Coast states and into the Carolinas. Flash floods remain possible, especially since the region has seen wet conditions over the past several weeks. Additionally, portions of the Southeast could see strong to severe thunderstorms, with strong winds and hail possible in southeastern Alabama, southern Georgia, and northern Florida. Elsewhere, an area of low pressure will spawn scattered showers and thunderstorms for the Northern and Central Plains over the next couple of days. On Thursday, some storms could have strong winds associated with them in the Central Plains. Some light showers are also possible in the Northeast through tomorrow, mainly in the form of rain, but some isolated thunderstorms can't be ruled out in northern Maine. Temperatures are forecast to be below normal generally east of the Continental Divide, though Florida should remain warmer than average before a cold frontal passage tonight into tomorrow. Cold morning lows will once again cause Freeze Warnings and Frost Advisories across the the Great Lakes, Ohio Valley, and Northeast. Cool high temperatures could set daily records for portions of the Southeast tomorrow, with highs only in the 60s. Meanwhile, temperatures are forecast to be 10 to 20 degrees above normal in the West, with temperatures in the 90s in some areas and eclipsing 100 degrees in the Desert Southwest.
