Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 356 AM EDT Sun May 27 2018 Valid 12Z Sun May 27 2018 - 12Z Tue May 29 2018 ...Subtropical Storm Alberto will bring heavy rainfall across the central and eastern Gulf as well as parts of the Southeast... ...Severe weather expected across the Plains through Tuesday... ...Well above average temperatures will continue across the Upper Midwest and Great Lakes... Subtropical Storm Alberto will continue a northward path over the next few days through the eastern Gulf of Mexico. Alberto is expected to strengthen into a tropical storm sometime Monday morning and will make landfall Monday evening. In the meantime, heavy rainfall will impact primarily Florida today along with coastal Georgia and South Carolina. By Monday night and into Tuesday morning, as Alberto makes landfall, heavy rain will impact the Florida Panhandle and south Alabama. As the storm moves inland, expect the heaviest axis of rainfall to also shift northward into central Alabama. Flash flooding is a concern with this storm. A moderate risk of flash flooding is possible for parts of the central Gulf Coast especially late Monday night and into Tuesday morning as Alberto nears the coast and makes landfall. Isolated tornadoes are possible central and south Florida--the Storm Prediction Center has highlighted this area in a slight risk. For the most current information on Alberto and its hazards, please see the National Hurricane Center (www.hurricanes.gov). Showers and thunderstorms are expected to continue across the Intermountain West and the Plains--particularly from Dakotas to the Texas Panhandle today and Monday. A frontal boundary will slowly move south and east across the Intermountain West and Great Basin today--with showers and thunderstorms expected across these regions. Convection will also fire off along the dryline in the High Plains of Colorado southward into the Texas Panhandle. By Monday and into Tuesday, as the front moves across the Plains and stretches into the Upper Midwest, showers and thunderstorms will develop along the boundary. These storms will have the capability of becoming severe--and the Storm Prediction Center has a slight risk across the Plains through Tuesday. High temperatures across parts of the northern Plains, Upper Mississippi and Upper Great Lakes will continue to see temperatures over 20 degrees above normal for this time of year. In the Upper Mississippi Valley, high temperatures today will be in the upper 90s. On Monday, these regions can expect low to mid 90s--with temperatures finally beginning to cool down slightly by Tuesday. West Texas and along the Rio Grande in southwest Texas can expect high temperatures in the low to mid 100s. Reinhart Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
