Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 258 AM EDT Sat Oct 5 2019 Valid 12Z Sat Oct 5 2019 - 12Z Mon Oct 7 2019 ...Fall weather becoming well established across much of the nation... A strong cold front passed through the Mid-Atlantic region and the Northeast on Friday, ushering in a much more pleasant autumnal airmass and a relief to the recent late season record breaking heat wave. Many locations across the Northeast and northern Great Lakes are having their first frost or freeze of the season. However, the frontal boundary has slowed down in its southward progress across the interior Southeast U.S. and the result will be a continuation of hot weather from Texas to the southeast Coast with some additional record highs likely. With the exception of some heavier showers near portions of the southeast coast, this front is not expected to produce widespread rainfall given the relatively dry atmosphere. Upper level troughing and a pronounced shortwave disturbance crossing the northern Plains will sustain an intensifying surface low from North Dakota to Hudson Bay through the weekend. The cold front from this storm system will bring in another cool and autumnal airmass across much of the central U.S. and this boundary should eventually reach farther south than the first cold front that recently exited the East Coast. Periods of rain are likely for the Upper Midwest and Great Lakes region on Saturday, and heavier rain is likely to develop on Sunday from Arkansas to the Ohio Valley as the front intercepts deeper moisture. There may be some strong thunderstorms across portions of the southern Plains as the front crosses this region. Hamrick Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
