Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 518 AM EDT Sun May 31 2020 Valid 12Z Sun May 31 2020 - 12Z Tue Jun 02 2020 ...Upper-level energy over Texas will aid in producing rain over the Western Gulf Coast... ...Temperatures will be 10 to 15 degrees above average over the Northern High Plains and 10 to 15 degrees below average over the Lower Great Lakes... ...Elevated to Critical fire weather conditions across the Southern Great Basin... Upper-level energy over Texas and moisture from the Western Gulf of Mexico will aid in producing showers and thunderstorms over the Western Gulf Coast Sunday through Tuesday. In addition, a front over the Northern Rockies will slowly move eastward to the Upper Great Lakes/Upper Mississippi Valley by Tuesday. The system will produce showers and thunderstorms over the northern Intermountain Region on Sunday. Overnight Sunday, showers and thunderstorms will develop over the Central Rockies and the Northern/Central High Plains, and by Monday will move into the Upper/Middle Mississippi Valley. Overnight Monday, the showers and thunderstorms will move into the Great Lakes. Ahead of this system, upper-level ridging will aid in producing temperatures 10 to 15 degrees above average over the northern High Plains. Critical fire weather conditions will develop across eastern Nevada, western/southern Utah, and northwest Arizona with south-southwest sustained winds of 15-25 mph and minimum relative humidity of 8-20% expected across the region. Elevated fire weather conditions are expected around the critical area, extending through Utah into northwest Colorado. These dry/windy conditions could spread any ongoing fires that were sparked by recent lightning. Upper-level troughing over the Lower Great Lakes will aid in producing temperatures 10 to 15 degrees below average. Also a front lingering over South Florida will aid in producing showers and thunderstorms over the region through Tuesday morning. Ziegenfelder Graphics available at
