National Weather Summary for Tuesday, June 23, 2009
NATIONAL WEATHER SUMMARY:
In the East, an area of thunderstorms slid down a warm front from southern Indiana to northern Florida through the day with some storms redeveloping in the afternoon and evening. These storms were feeding on very warm and humid air, and that allowed them to reach severe levels. Reports of severe storms occurred from the early
morning through the afternoon and evening hours. Winds gusted to
50-60 mph in the stronger storms and caused trees to fall
throughout the region. A wind gust of 71 mph was reported in Cross
Plains, Tenn. And in the evening hours near Otwell, Ind. a mobile
home was tipped on its side due to strong wind gusts.
Oppressive heat continued in the southeast where temperatures reached the century mark for portions of Florida, Georgia, and Alabama. Cooler air remained over the northeast where rain showers flirted with the coast and temperatures remained below normal once again.
Across the central portion of the country, oppressive heat
continues for many as very warm and humid air sits from the Gulf
Coast to Upper Midwest. Most major urban areas are under Heat
Advisories as the heat index is expected to reach 105-110 again
Tuesday. Thunderstorm winds gusted up to hurricane force in
thunderstorms across the central Plains and Missouri Valley. Winds
gusted as high as 75 mph in storms in Lees Summit, Mo. around dawn
and that helped to knock down trees and power lines. Gusts were
nearly 70 mph in portions of Nebraska and hail was large enough in
diameter at around 2.25 inches to dent cars in the city of Seward.
This activity also brought flooding as well with heavy rain
flooding an apartment building basement very early in the morning
over Polo, Ill.
In the West, rain and thunderstorms were heavy over northern Montana. As much as 1.14 inches of rain fell in Cut Bank and in
Kalispell there was a record amount of rain for the day at 0.65
inches. Some of the showers spread westward over northern Idaho and eastern sections of Washington and Oregon. Mostly quiet weather
conditions were found over the remainder of the region.
