Weather Underground midday recap for Saturday, April 25, 2015
A low pressure system moved across the central Plains on Saturday, while a separate system developed over the Intermountain West.
An area of low pressure shifted eastward over the central Plains and the middle Mississippi Valley. This system drew moisture from the Gulf of Mexico, which fueled strong to severe thunderstorms across the western and central Gulf Coast. Severe thunderstorm warnings were issued in southeast Louisiana, southern Mississippi and southwest Alabama. Hancock, Miss., reported 1.5 inch sized hail. Gonzales, La., reported a midday total of 1.59 inches of rain. Just to the east, tornado watches were issued in northern Florida and southwest Georgia.
The same low pressure system ushered heavy rain and strong thunderstorms across the middle Mississippi Valley, the upper Midwest, the Ohio Valley and the Mid-Atlantic. Tornado watches were issued in eastern Missouri, southern Illinois, southern Indiana and western Kentucky. Kankakee, Ill., reported a midday total of 1.32 inches of rain.
Out west, a low pressure system moved east southeastward over the upper Intermountain West. This system pushed moderate to heavy snow showers over the northern and central Rockies, while heavy rain and thunderstorms fired up over the northern Plains. A cold front stretched across the Great Basin and northern California. This frontal boundary generated heavy snow across the higher elevations of the Sierra Nevada and the Ruby Mountains. Alpine Meadows, Calif., reported a midday total of 10.0 inches of snow. Moderate rain also affected central and northern California. Placerville, Calif., reported a midday total of 1.32 inches of rain.
