Friday Severe Risk. A few isolated severe storms may fire later today from the Mid Atlantic states westward to Memphis, a second risk area from northeastern Colorado into the Dakotas.
Saturday Severe Threat. By Saturday the risk of hail/damaging winds shifts from the central Plains iinto southern and central Minnesota and western Iowa.
Friday Rainfall. The latest WRF/NAM model shows potentially severe storms rumbling across the Dakotas later today, a broad region of heavy showers and storms from Florida up the east coast into upstate New York, puddles predicted westward to Memphis and Little Rock. Most of the west stays dry - more 100-degree sunshine across Texas.

- By mid-afternoon, Kennedy Space Center was hit by a series of rain squalls – and at least one lightning strike roughly a third of a mile from the shuttle's launch pad. NASA officials immediately dispatched technicians to check for damage, though there were no immediate indications of any.
- Nonetheless, preparations for the launch remained underway.
- The Rotating Service Structure protecting Shuttle Atlantis was pulled away Thursday around 30 minutes later than planned due to the weather.
- Friday's launch of the space shuttle Atlantis remains iffy, with NASA saying Thursday morning there is a 70-percent chance that the launch may be delayed. And chances for bad weather scrubbing a Saturday lift-off are 60 percent.
- A tropical wave has moved into the Space Coast area from the south, threatening rain, lightning and overcast conditions Thursday and continuing into Friday, when Atlantis is scheduled to lift off at 11:26 a.m. ET.
- If late-morning weather forces NASA to scrub the launch, Saturday may be nearly as problematic for an 11:02 a.m. launch. If NASA reschedules for Sunday, launch time would be 10:38 a.m.
- An elongated low pressure system located about 300 miles southwest of Tampa, Florida has become a little better defined during the past few hours.
- In addition, surface pressures have decreased over the eastern Gulf of Mexico during the last 24 hours.
- Environmental conditions are expected to become marginally conducive for some additional development of this disturbance.
- There is a 40% chance of this system becoming a tropical or subtropical cyclone during the next 48 hours as it moves slowly northward or north-northeastward.
- Regardless of development, this weather system will produce periods of locally heavy rainfall across most of the Florida Peninsula and the eastern Florida Panhandle during the next couple of days.

Heavy Rains Pound Denver Area, Street Flooding Traps Cars. The Denver Post has the latest on severe storms that roared through the Denver area late Thursday: "A severe thunderstorm is dropping heavy rain, flooding streets, swamping cars, sweeping away manhole covers and causing power outages as it moves through the metro area. Denver Fire Department crews has made scores of water rescues as more than 10 cars at a time found themselves trapped in rising, fast water, said Lt. Phil Champagne. "It's widespread through the city, but the northeast quadrant has been hard hit," he said. "But it's been all over the board, and it's been fast and furious all afternoon long." Xcel Energy reported that, as of 8 p.m., 18,000 customers were still without power. Xcel spokesman Mark Stutz said Xcel called in extra crews to help restore the power. The National Weather Service reported numerous gauges indicated 2 inches of rain fell on parts of Denver in less than an hour between 4:15 p.m. and 5:15 p.m. Denver and Aurora are under a flash flood warning until 10:15 p.m. for parts of Denver, Arapahoe and Adams counties. A severe thunderstorm warning expired at 6 p.m. The National Weather Service also issued a flash flood warning for central Boulder County until 9:15 p.m. "This is a life-threatening situation," the National Weather Service in Boulder stated.
