A stationary front will be the focus for daily showers and thunderstorms capable of widely scattered flash flooding and severe weather from the High Plains to the Ohio Valley. Monsoonal thunderstorms could cause local flash flooding across the Southwest and the Great Basin. Dangerous heat continues across the Central Plains and Southeast. Many areas will see their hottest temperatures of the year. Read More >

Instructions for the proper application of the data type designator
1. The designator specified in this table should be used to the greatest extent possible to indicate the data types of the data contained within the text of the bulletin.
2. Where the data type does not correspond exactly with the designator, the designator for the most approximate type of the data may be used.
3. The NWS will assign deginators to this table in place of the unassigned designators when needed.
