Scattered Severe Storms and Isolated Flooding in the Plains; Inclement Weather in the Mid-Atlantic

Isolated strong to severe thunderstorms capable of strong gusts, hail, and isolated flash flooding will be possible across parts of the Plains. A slow-moving low pressure system will produce scattered showers and thunderstorms and dangerous rip currents across the Mid-Atlantic. Read More >

High temperatures throughout Central California Monday afternoon will be two to four degrees below normal for this time of year. Maximum temperatures across Central California Tuesday afternoon will be a couple of degrees cooler than Monday afternoon.
A few strong thunderstorms are possible in the Sierra Nevada north of Tulare County from 12 PM PDT Monday afternoon until 8 PM PDT Monday evening. Small hail and wind gusts near 45 miles per hour are a couple of hazards associated with strong thunderstorms. In addition to dangerous cloud to ground lightning strikes, any thunderstorm can produce intense rainfall rates, leading to localized flooding.

What is Skywarn?

The effects of severe weather are felt every year by many Americans. To obtain critical weather information, NOAA's National Weather Service (NWS), part of the U.S. Department of Commerce, established SKYWARN® with partner organizations. SKYWARN® is a volunteer program with nearly 290,000 trained severe weather spotters. These volunteers help keep their local communities safe by providing timely and accurate reports of severe weather to the National Weather Service. Although SKYWARN® spotters provide essential information for all types of weather hazards, the main responsibility of a SKYWARN® spotter is to identify and describe severe local storms. In the average year, 10,000 severe thunderstorms, 5,000 floods and more than 1,000 tornadoes occur across the United States. These events threatened lives and property. Since the program started in the 1970s, the information provided by SKYWARN® spotters, coupled with Doppler radar technology, improved satellite and other data, has enabled NWS to issue more timely and accurate warnings for tornadoes, severe thunderstorms and flash floods.

SKYWARN® storm spotters are part of the ranks of citizens who form the Nation's first line of defense against severe weather. There can be no finer reward than to know that their efforts have given communities the precious gift of time--seconds and minutes that can help save lives. While the main role of a storm spotter is to be their community's first line of defense against dangerous storms, they also provide important information to NWS warning forecasters who make critical warning decisions. Storm spotters play a critical role because they can see things that radar and other technological tools cannot, and this ground truth is critical in helping the NWS perform our primary mission, to save lives and property.
