Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 314 PM EDT Tue May 07 2019 Valid 00Z Wed May 08 2019 - 00Z Fri May 10 2019 ...Active weather pattern will bring a risk of severe weather and flash flooding to the Central US... ...Snow is expected in the Rockies and in the Great Lakes near Lake Superior... An active springtime weather pattern will continue across the Central U.S. this week. A stalled front in the Central Plains and Midwest will give way to a developing area of low pressure by Wednesday Night. This low will then lift into the Great Lakes on Thursday, with the cold front pushing east and southeast toward the Mississippi River. The result will be rain and thunderstorms gradually spreading from the Plains toward the Mississippi Valley over the next couple days. There is a risk of severe weather and flash flooding with the thunderstorms. In general, the greatest risk for severe weather will be focused from the southern Plains into the Arklatex region tonight and Wednesday. Tornadoes, damaging winds, and large hail will all be possible. The greatest risk of flash flooding will be focused from the central Plains into the Arklatex region. However, chances for severe weather and flash flooding will extend as far north as the western Great Lakes. Other than the aforementioned areas in the central U.S., precipitation will also be likely in the central Rockies. At higher elevations, this is likely to fall as snow. The heaviest snow accumulations are likely to be above 9000 feet, where the probability of receiving 12 inches of snow is greater than 50 percent in the ranges of central Wyoming and Colorado. Temperatures will be well below average behind the front in the Rockies and Plains. High temperatures on Wednesday and Thursday may be as much as 25 to 35 degrees below average in the central High Plains from western Nebraska into eastern Colorado and western Kansas. More tranquil weather is anticipated along both of the coasts, with only isolated to scattered showers and light rain totals expected. North of the stalled front along the East Coast, temperatures may be below average in the Northeast. Otherwise, warm weather is expected along much of the West Coast and in much of the East -- from the Mid Atlantic southward. Lamers Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
