Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 332 AM EDT Mon Aug 12 2019 Valid 12Z Mon Aug 12 2019 - 12Z Wed Aug 14 2019 ...Hot and humid conditions across the South and heavy rain from the Midwest to southern New England... The upper level trough initially over the northern plains Monday morning is forecast to cross the Upper Midwest and Great Lakes region through the beginning of the work week. This will support a surface low that will track across the Midwest and then the Ohio Valley and Mid-Atlantic region, with a band of moderate to heavy rainfall extending from Iowa to southern New England. Severe storms are also likely for parts of this same general area, and the Storm Prediction Center has additional information pertaining to this. Another story making weather headlines over the next couple of days will be the oppressive heat and humidity across the south-central U.S., especially from eastern Texas to northern Florida. Widespread heat advisories are in effect, and even excessive heat warnings are posted across parts of the lower Mississippi River Valley. This is in response to a strong upper level ridge anchored over the region, with highs well into the 90s and low 100s and dewpoints in the 70s, producing heat indices on the order of 105 to 115 degrees during peak afternoon heating. Some record high temperatures may also be set. Elsewhere, drier weather conditions are forecast to return to the southwestern U.S. early this week as the monsoon temporarily abates. Warmer and more humid conditions will return to much of the East Coast after a rather pleasant weekend, and scattered areas of heavy rain and strong storms can be expected for the Florida Peninsula.
