Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 400 AM EDT Fri Sep 28 2018 Valid 12Z Fri Sep 28 2018 - 12Z Sun Sep 30 2018 ...Much below normal temperatures across the northern and central Plains into the upper Great Lakes... ...Lingering showers and thunderstorms expected along the Gulf Coast... ...Mixed precipitation expected for the higher elevations of the northern Rockies... A real taste of fall is expected for the northern and central Plains as well as the upper Great Lakes for the next few days under the influence of a cool Canadian high pressure system. Meanwhile, with an upslope flow expected to persist along the eastern slopes of the northern Rockies, rain is forecast to mix with or change over to snow over the higher elevations. The cool air should continue to plunge southward into the central Plains today and should reach the southern High Plains Saturday morning before retreating for the remainder of the weekend. Some rain should develop in the central Plains during the weekend as the cold front lifts northward as a warm front. The Mid-Atlantic into New England will see rain moving steadily eastward through the morning followed by gradually clearing tonight as a cold front pushes further to the south. The trailing front is forecast to stall near or just inland from the Gulf Coast during the weekend. This will keep a good chance of showers and thunderstorms along the southern tier states today and into the weekend. Elsewhere, dry and warmer than normal conditions are expected to continue in the western U.S., with a high level of fire danger across the interior sections. Please refer to the Storm Prediction Center for further details on the fire danger outlook. It appears that the very outer edge of the moisture and dynamics associated with Hurricane Rosa could reach the Desert Southwest later on Sunday where isolated thunderstorms could develop.
