redOrbit Meteorologist Joshua Kelly
Big Story Weather Outlook for July 26: A frontal boundary extending from the Great Lakes back towards the Southern Plains is going to be the firing range for today´s severe weather with the major concern being large hail and damaging winds. A few tornadoes may also be possible in the Ohio River valley region. The Southeast will see afternoon thunderstorms again today along with plenty of heat which will be found from places like Baltimore with a high in the upper 90´s along with Mobile AL where highs will be in the mid 90´s. Back west into the Southern Plains places like Houston will see isolated thunderstorms along with high temps in the lower 90´s. The western 2/3rds of the United States will be enjoying a nice day with cooler temps from places like Sioux Falls SD where high temps will be in the upper 70´s to lower 80´s, while along the west coast another nice day will prevail for places like Seattle where the high temps will be in the lower 80´s.
Big Story Weather International Outlook: Partly cloudy skies will be found throughout Japan, while a frontal boundary will bring showers and isolated thunderstorms to the Korea´s. The monsoonal trough will again be working strong throughout India and Southeast China. The Middle East will be dry and warm. An area of showers will be found from Spain eastward into France. Low pressure will bring multiple showers to England and the Olympics for today. High pressure will impact the Western side of South America with partly cloudy skies. High pressure will be influencing the weather on the western side of Australia, while the central and eastern part of Australia will see a weak frontal boundary moving through the area bringing with it a chance of showers to this part of Australia.

Tropics Watch: Focusing our attention on the region just off the coast of Central Africa, we see that temps this morning are in the 26C range with a small pocket of 28C near the coast. This area is going to need to be watched closely as there is a possible wave that may exit Africa in the next few days that could start making its long journey across the Atlantic with plenty of warm water ahead of it and a little bit more favorable upper air conditions setting up in the region.
