Download The Climate Impact Company Medium/Extended-range U.S. Forecast
Pictured: The Climate Impact Company medium/extended-range U.S. temperature anomaly forecasts indicates the heat core shifts westward but still affects the Great Plains.
Extreme heat bakes the East-Central/Mid-South (and East) U.S. this week. Along the top rim of the hot dome is persistent severe thunderstorms and attendant heavy rain. Gradually, this frontal boundary will shift south and end the heat wave this weekend and early next week. The front washes out in the Deep South while focusing thunderstorm activity suppressing heat in that region. As August approaches the Gulf of Mexico becomes more tropically active. Not necessarily tropical cyclones but widening areas of thundershowers associated with tropical waves. The showery regime gradually cools the Gulf region while to the north the remainder of the East observes a changeable weather pattern but without excessive heat. The upper ridge pattern shifts westward during this time amplifying an already hotter than normal summer. The eastern edge of that hot regime rests in the Great Plains. So…more hot weather and generally dry conditions ahead for most of the Great Plains into August.
