Scattered to widespread showers and thunderstorms will persist into Friday across the Southeast and southern Mid-Atlantic states before the surface low pressure system and stalled front finally moves offshore. Strong to severe thunderstorms, along will periods of excessive rainfall, can be expected for portions of Florida, Georgia and South Carolina; where the SPC and WPC has Slight Risks in effect. The precipitation will taper off through the day on Friday as the system exits and drier/cooler air begins to moderate the airmass over the Southeast. A low pressure system track trekking through the Great lakes regions today will continue progressing eastward, passing through the Northeast on Friday and then advancing offshore this weekend. On the northern and western flanks of this storm system, a cold front will push southward leading to an injection of colder air along and east of the Mississippi River by the start of the weekend. This will lead to wintry weather, most notably across the Upper Peninsula of Michigan where precipitation enhancement from Lake Superior will aid snow accumulations of 6 to 12 inches of snow. The best chances for snow in the Northeast and Mid-Atlantic will be in the Appalachians with light accumulations possible. Additionally, there will will be coastal rains for the northern Mid-Atlantic while some snow may mix in with the rain in portions of southern New England. Pacific cold front moving inland today is ushering multiple rounds of rain and mountain snows to coastal areas and into the Interior this afternoon. Rain and mountain snows is expected to spread across the Intermountain West by Friday. Snow will be heavy at times, especially for the highest peaks of the Cascade and Olympic Ranges. For much of the Southwest and the Plains, mild and dry conditions are expected to continue. By the weekend, much of the Midwest will see temperatures anomalies ranging between 10 to 20 degrees above normal.
