Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 247 PM EDT Tue Jul 09 2019 Valid 00Z Wed Jul 10 2019 - 00Z Fri Jul 12 2019 ...Area of low pressure has a high chance to develop into a tropical cyclone in the northern Gulf of Mexico... ...Threat of heavy rainfall will begin to ramp up along the central Gulf Coast... ...Severe thunderstorms possible in the Northern Plains Tuesday and Great Lakes Wednesday... An area of low pressure will move southwest from the Florida Panhandle into the northern Gulf of Mexico tonight, and then is likely to become better organized this week. The National Hurricane Center (NHC) is forecasting a high chance of this system developing into a tropical cyclone by Thursday. Please refer to Tropical Weather Outlooks from NHC for the latest on this potential system in the Gulf of Mexico. The low should begin delivering some heavy rainfall to the central Gulf Coast over the next couple days as it drifts slowly west over the Gulf of Mexico. Outside of the system's circulation, record warm low temperatures are possible across portions of the Southeast and Gulf Coast within a hot and humid summertime air mass. Another low pressure system moving across the Northern Plains and Great Lakes will produce thunderstorms over the Northern Plains through tonight and Great Lakes on Wednesday, with heavy rains expected for the Northeast on Thursday. Severe weather is possible with the thunderstorms, and large hail and damaging winds are the primary hazards. Localized flash flooding will also be possible. Cooler weather is expected behind an associated cold front, with highs in the 70s to lower 80s over much of the northern Plains on Wednesday, and western Great Lakes on Thursday. Increasingly hot temperatures are expected across the western United States with time as the jet stream retreats northward. By Thursday, highs in the 90s will be commonplace, with 110s expected in the Desert Southwest. Lamers Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
