A strong low pressure system inched across the western and central Gulf Coast on Friday. This system interacted with warm, humid air from the Gulf of Mexico to produce strong to severe thunderstorms over the region. A severe thunderstorm warning was issued in southeast Mississippi, while flash flood watches were issued across eastern Texas, Louisiana, Mississippi and southeast Arkansas. Five trees reportedly blew down in Destrehan, Louisiana, while Burns Point, Louisiana, recorded wind speeds of 52 mph. In addition, flash flood warnings were issued in southeast Texas, southern Louisiana and northwest Mississippi due to heavy rain associated with these thunderstorms. Baton Rouge, Louisiana, reported a midday total of 2.69 inches of rain. Lafayette, Louisiana, reported a midday total of 1.88 inches of rain.
Just to the north, high pressure kept conditions clear across the southern and central Plains, as well as the middle and upper Mississippi Valley. Temperatures dropped 10 to 20 degrees below normal from the central Plains to the southern Appalachians. High pressure also kept the northern Mid-Atlantic and the Northeast clear of precipitation.
In the West, scattered showers and thunderstorms developed over the Great Basin and the Southwest due to a surge of monsoonal moisture over the region. Flash flood watches were issued over the northern Sierra Nevadas on Friday.
