Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 317 PM EDT Mon Jun 24 2019 Valid 00Z Tue Jun 25 2019 - 00Z Thu Jun 27 2019 ...A quieter weather pattern returning to much of the nation by mid-week... After several days of active weather across the central and eastern U.S., the weather pattern is expected to become less eventful by the middle of the week. The upper level trough lifts out of the Northeast U.S. on Tuesday, with a zonal flow pattern in place across most of the continental U.S. Showers and thunderstorms are likely from the Ohio Valley to the Northeast through Tuesday evening as a weak cold front crosses the region. Although the air will be somewhat drier behind the front, temperatures are not expected to cool down that much. By Wednesday, the next upper low begins affecting the Pacific Northwest along with a cold front moving inland. An increase in showers is likely from northern California to Washington state in conjunction with this. Another thing making weather headlines through mid-week will be the potential for excessive heat for portions of the Southeast U.S., and heat advisories may be needed at times for this region. The opposite will be true from the northern plains to the Great Lakes, where temperatures will be below seasonal averages as a refreshing airmass settles in behind the cold front. D.
