Active weather continued across the nation on Friday, with showers and thunderstorms across the Great Lakes, monsoonal storms in the Southwest, and hot conditions over the East.

A ridge of high pressure over the Eastern Seaboard maintained northward flow from the Gulf of Mexico. This maintained warm and humid conditions across the Eastern Valleys. Heat advisories remained in effect from the Midwest through the Northeast as high temperatures remained in the mid- to upper 90s, with heat index values over 100 degrees.

The highest heat index value was reported at Lakehurst, N.J., with a midday heat index value up to 121 degrees. Just to the north, a low pressure system over eastern Canada created a cold front that moved over the Great Lakes and into the Ohio River Valley. Showers and thunderstorms developed along this front, some of which turned severe with strong winds and large hail.

Numerous trees and power lines were reported down across Michigan. In the Southeast, warm and humid conditions allowed for afternoon shower and thunderstorm activity. Scattered storms developed from Texas through the Virginias, while an area of low pressure in the Gulf of Mexico brought heavy rainfall and strong storms to parts of western Florida and the panhandle of Florida.

Meanwhile in the West, a monsoonal moisture continued to stream northward across the Desert Southwest. Periods of heavy rainfall were associated with these storms, thus, flash flood watches have been issued for parts of Colorado, Utah, and New Mexico.

FRIDAY'S WEATHER EXTREMES:

HIGHEST TEMPERATURE (DEGREES F).........................106 Lakehurst, N.J.

HIGHEST HEAT INDEX (DEGREES F)..........................121 Lakehurst, N.J.

ON THIS DATE....... The hurricane season of 2005 has been strange, but the season of 1886 may have been even stranger. On this date of that year, the third hurricane in a month crossed Florida and caused serious damage to Cedar Keys and Jacksonville.
