...Major storm system to bring heavy rain, gusty winds, and coastal
flooding from Florida to the Mid-Atlantic this weekend...

...Light snow over parts of the Upper Midwest...

The big weather maker for this weekend will be an intense storm tracking
across Florida and up the Southeast coast with likely impacts to travel as
well. This storm will bring an array of weather including very heavy
rainfall, gusty winds, coastal flooding, and some threat for severe
weather from Florida to the Mid-Atlantic states. The latest rainfall
forecast from WPC through Sunday evening shows potential for widespread
2-4 inches of rain, with locally higher amounts especially along the
Georgia and South Carolina coasts, increasing the threat for flooding and
flash flooding. Some of these rainfall amounts could also approach or
exceed daily rainfall records for mid-December. Gusty winds and onshore
flow will also likely bring coastal flooding along much of the East Coast
into early next week. The low pressure system will deepen as it lifts up
the East Coast next Monday and Tuesday as well, past the short range
period, with rain and wind impacts moving into the Northeast.

Elsewhere, a couple of fronts tracking from the Plains into the Midwest
will focus showers from the Southern Plains/Gulf Coast northward into the
Upper Great Lakes. Colder air filtering in behind the fronts may bring a
period of light to moderate snowfall across the Upper Midwest, with
generally only a few inches of accumulation forecast. Out West, a cold
front moving towards California may begin to bring some rain showers to
portions of the northern and central California coast by Sunday afternoon.
Much of the U.S. this weekend will experience well above average
temperatures, with daytime highs 10 to 20 degrees above average across the
Western U.S., Northern tier, and into the Northeast.
