NATIONAL WEATHER SUMMARY:
Across the East, showers and cool weather continued across Maine with dry and seasonable weather across the Mid Atlantic states. A stalled frontal boundary across the Southeast brought heavy rain and scattered severe storms to portions of southern South Carolina. Another round of strong to severe storms moved from Alabama to central Georgia later in the afternoon. Numerous hail and wind damage reports resulted from the storms. Where it wasnt raining

It was even warmer across Florida with several record highs being

A gloomy Mothers Day was experienced across the Central Plains with rain showers and cool weather throughout the day. Stationary front across the Southeast extended back to southern Arkansas and the Red River Valley region where more rain and thunderstorms fell. A complex of thunderstorms which formed over southern Oklahoma held together all day as it moved
across southern Arkansas, northern Louisiana and into central and
southern Mississippi by the end of the day. Storms became severe as
they spread across northeast Louisiana and central Mississippi with
many reports of trees and power lines down.
In the West, clouds and light rain showers continued to bring below average temperatures east of the continental divide from
Montana to eastern Colorado. Weather was rather tranquil over the
remainder of the west with a large dome of high pressure bringing
abundant sunshine to most of the region. Temperatures were really
heating up in the Southwest with some 100 degree highs common
across the deserts. Douglas, AZ established a new record high for
