Thick heat and humidity in place from the nation's midsection to the Southeast will provide fuel for some more drenching thunderstorms today.
As a few potent upper-level disturbances pass through the heat, some of the storms could turn severe, especially across the lower Missouri and mid-Mississippi valleys, as well as a portion of the South.
Kansas City and St. Louis, Mo., Paducah, Ky., and Macon, Ga., are among the cities at higher risk for a gusty storm versus the rest of the Midwest and South, where scattered storms will be common.
Powerful wind gusts in excess of 50 mph and some hail will result from a few complexes of thunderstorms through early tonight. Vivid lightning and flooding downpours will be a staple in any storm as well.
It is plausible that one or two storms could rotate and spawn a tornado; however, the possibility of numerous twisters appears low.
Any tornado warning must be taken seriously and those warned should seek safe shelter regardless of whether a tornado is actually confirmed with the warning.
Even non-severe storms can be dangerous. Lightning injured four people on the beach in Wildwood Crest, N.J., on Wednesday.
Also on Wednesday, there were numerous reports of strong wind gusts and hail from southern Missouri to Virginia.
The storm system that pushed through the northern Plains slated to arrive in Missouri today also produced wind damage and hail from Colorado to Wisconsin.
Unfortunately, the northern Plains will have little time in between severe weather episodes as a multi-day outbreak is expected to take shape this evening over the Dakotas.
Meanwhile, the Northeast, plagued by several days of isolated but drenching storms will finally catch a break late this week as high pressure builds in from the west. This weekend, however, the storms will return.
Following a southward push of cool, dry air at midweek, clouds, showers and higher humidity will return to the Northeast.
El Nino is forecast to last into the fall of 2015, but will it be enough to break expanding drought conditions along the Pacific coast of the United States?
Another round of storms will fire across the northern Plains at midweek with the chance for isolated tornadoes.
Andres has begun to weaken over the eastern Pacific, but a new threat has developed closer to Mexico.
The weather pattern that delivered drenching rain and flooding to Texas and the southern Plains during May will soak the Southeast states for the next week or two.
With summer just around the corner, many in the United States are preparing for exciting outdoor activities, but coupled with the summer fun comes the return of the pesky and potentially disease-ridden mosquito.
