Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 351 PM EDT Sun Jun 23 2019 Valid 00Z Mon Jun 24 2019 - 00Z Wed Jun 26 2019 ...Active weather pattern continues for the central U.S. to begin the work week.. The synoptic scale upper trough that has resulted in unseasonably cool conditions across the Intermountain West and Rockies will cross the Plains and Upper Midwest tonight and into Monday. Ahead of this trough and the cold front associated with it will be a plume of deep moisture surging northward from the Gulf of Mexico. Widespread moderate to heavy rainfall is likely across eastern Texas and extending eastward towards Mississippi through Monday evening, with the potential of 1 to 3 inches of rainfall for some areas. A Moderate Risk of excessive rainfall currently exists from northeast Texas to central Arkansas through Monday morning, with rainfall intensity abating some by Monday night and beyond. Some severe storms are also likely for this same general area, and additional strong to severe storms are expected to form across the Ohio Valley and Appalachians Monday afternoon and evening. Another thing making weather headlines early this week will be the potential for excessive heat from southern Texas to the Southeast Coast. Heat advisories are likely for portions of the Gulf Coast region with highs reaching the 90s coupled with oppressive humidity levels. The opposite will be true across the Rockies and the north central U.S. where temperatures will be below seasonal averages as a refreshing airmass settles in behind the cold front. D.
