NEW Details on Soon-to-Be Hurricane Isaias: youtube.com/watch?v=w0ZSZbpF…

Tropical Depression Nine has formed in the Gulf, soon to be Isaias. Here's the latest: youtube.com/watch?v=rouurIuP…

All severe hazards appear possible across parts of the Plains tomorrow (Wed, Sep 30). As an upper trough and the remnants of Polo move out of the Rockies, a deep plume of moisture and strong low-level shear will overlap from Texas to Nebraska. At the triple point in Kansas and Southern Nebraska, a few transient supercells may develop by mid-afternoon, assuming adequate destabilization occurs. Strong low-level shear should support at least modest low-level rotation, which could produce a few weak tornadoes. Isolated large hail, and damaging winds will be possible as well. Further south, a line of storms, mainly producing flash flooding, could produce sporadic strong-severe wind gusts, and perhaps a tornado or two.

A Nor'easter may impact the Mid-Atlantic and New England late this week, and into this weekend. Guidance is in very good agreement that a strong low will develop off the East Coast, bringing heavy rain and strong winds to coastal, and even interior regions. There remains a fair bit of uncertainty regarding the intensity and the track of the system, with still some potential of minimal to no impacts, but there is at least medium confidence in a moderate-high impact event, at least for coastal regions. Updates will be provided throughout this week.

Some tornado threat (alongside a wind/hail threat) may develop across parts of the Dakotas this evening as a line of supercells develops in North Dakota in a moderately unstable and sheared environment. Although large hail will likely be the primary hazard, a couple of tornadoes will be possible as well. Across parts of South Dakota, the threat is more conditional, as storm development is uncertain. If storms develop between 5-8pm CDT, the threat for large hail, and a couple of tornadoes may materialize. A strong tornado won't entirely be ruled out, given elevated shear profiles, but the overall tornado threat should generally remain on the lower-end.

There is a risk of all severe hazards across parts of Western New York and Central Pennsylvania late this afternoon, and into this evening. A mix of supercells and line segments are forecast to move into an unstable and highly sheared environment. If the storm mode remains more cellular, tornadoes and hail will be the dominant hazards, with a strong tornado or two not being ruled out. However, if the storm mode remains more linear, damaging winds will be the primary hazard, although embedded tornadoes will be possible as well.

Severe thunderstorms are possible across parts of the Great Lakes and Northwest region on Wed, September 2nd. A strong upper trough will move atop a band of strong instability across the region, perhaps producing multiple rounds of strong-severe storms, or a long-lived complex. Uncertainty remains regarding the area, timing, and severity of the severe potential, but updates will be made when details become more clear.

At least a couple of tornadoes will be possible across parts of Illinois, Indiana, Michigan and Ohio tomorrow afternoon/evening. A cold front will slowly move through the region, supporting a risk for a few isolated supercells in a moderately unstable and sheared environment. Damaging winds, large hail, and some tornado threat will develop from the stronger storms.

NEW Video! - Southern Heatwave, MORE Severe Weather & Tropics! youtube.com/watch?v=vaqJ0_wA…

A significant heatwave will impact the Southern U.S. late this week, into next week, as a strong upper ridge builds and sits over the region. Temperatures are forecast to be around 10-15° above average, with daytime highs in the 100s for many. Some areas will experience drier air, with dew points in the 50s-60s, which will keep heat indices a bit lower, but for many across the Southeast, dew points in the 70s will bring heat indices up to the 105-110 degree range for many. Bottom line, significant and dangerous heat will be in place for many across the South over the next 7-10 days.

DESTRUCTIVE Severe Thunderstorm Warning for Aurora, Bolingbrook, Naperville, Joliet, Oak Lawn & South Chicago, IL. Take cover now! Wind gusts up to 80mph are possible, including the potential for an embedded tornado.

There is the potential for a long-lived MCS or Derecho event to take shape across parts of the Northern Plains and Midwest, beginning late today, and through the day tomorrow (Aug 10-11). There remains some uncertainty regarding the evolution of convection, and whether or not there will be one long-lived MCS (potentially derecho), or multiple smaller clusters. Regardless of storm mode, timing and evolution, damaging winds will be the primary concern, with some storms capable of 75mph+ gusts, along with large hail, and isolated tornadoes. Even if a derecho does not materialize, a very active period of severe weather is expected across portions of the region over the next ~36 hours.

Choose your fighter! Multiple areas of severe potential exist for today across parts of the country, with the greatest severe threat being from Washington, D.C. to NYC, mainly in the form of damaging winds this afternoon. Elsewhere, mostly isolated severe gusts and/or hail will be possible.
