Headquartered at the National Weather Center in Norman , Oklahoma , the Storm Prediction Center is tasked with forecasting the risk of severe thunderstorms and tornadoes in the contiguous United States. It issues convective outlooks , mesoscale discussions , and watches as a part of this process. Convective outlooks are issued for the following eight days issued separately for Day 1, Day 2, Day 3, and Days 4—8 , and detail the risk of severe thunderstorms and tornadoes during the given forecast period, although tornado, hail and wind details are only available for Days 1 and 2. Day 3, as well as 4—8 use a probabilistic scale, determining the probability for a severe weather event in percentage categories. Mesoscale discussions are issued to provide information on certain individual regions where severe weather is becoming a threat and states whether a watch is likely and details thereof, particularly concerning conditions conducive for the development of severe thunderstorms in the short term, as well as situations of isolated severe weather when watches are not necessary. Watches are issued when forecasters are confident that severe weather will occur, and usually precede the onset of severe weather by one hour, although this sometimes varies depending on certain atmospheric conditions that may inhibit or accelerate convective development. The agency is also responsible for forecasting fire weather indicating conditions that are favorable for wildfires in the contiguous U.

Arkansas Democrat-Gazette. Tornado Watch These tools are NOT operationally supported. The probability of ice accumulations of 0. A few tornadoes likely with a couple intense tornadoes possible Widespread large hail likely with isolated very large hail events to 2 inches in diameter possible Widespread damaging wind gusts to 70 mph likely SUMMARY Day 3 outlooks refer to the day after tomorrow, and include the same products categorical outline, text description, and probability graph as the Day 2 outlook. April 1, This indicates that the risk for severe weather is also valid in that general area of the other side of the border or oceanic boundary. A front extending from the Mid-Atlantic to the Central Plains will move southward to the Southeast to the Lower Mississippi Valley before dissipating by Sunday morning.

Our mission is to provide timely and accurate forecasts and watches for severe thunderstorms and tornadoes over the contiguous United States. The SPC also monitors for hazardous winter weather and fire weather events and issues specific products for those hazards. We use the most advanced technology and scientific methods available to achieve this goal.

Excessive Rainfall Forecasts Interactive Page :. An isolated strong tornado or two is also possible. This pattern looks to persist through much of next week. Extremely Critical areas are issued relatively rarely, similar to the very low frequency of high risk areas in convective outlooks see List of Storm Prediction Center extremely critical days.
