Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 342 PM EDT Mon Mar 27 2017 Valid 00Z Tue Mar 28 2017 - 00Z Thu Mar 30 2017 ...Active weather pattern across the southern tier states with severe weather and heavy rainfall possible... A stormy weather pattern is expected across much of the central and southern Plains going into the middle of the work week. With a closed upper level low tracking eastward from the southern Rockies to the central Plains, along with an occluded surface low, expect shower and thunderstorm coverage to significantly increase across Texas, Oklahoma, and Kansas by late Tuesday and especially into early Wednesday. Severe weather and heavy rainfall are likely with some of the thunderstorms that develop, and flash flooding will be possible where storms repeatedly form over the same areas. Temperatures are expected to be above seasonal averages across much of the central and eastern U.S. ahead of the low pressure system over the Plains. It will also be rather humid for this time of the year from Texas to the Deep South, and some overnight lows near the Gulf Coast may remain at or above 70 degrees. Cooler than average temperatures are expected near the upper low across the Four-Corners region, with significant snowfall likely for the higher elevations of Utah, Colorado, and Wyoming. It will also remain colder than normal for much of New England, which should remain north of the frontal boundary. Elsewhere across the continental U.S., expect additional rain and mountain snow to return to the Pacific Northwest as a Pacific front makes its way inland. Warm and dry conditions are expected to continue for the Florida peninsula through mid-week. D. Hamrick Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
