This Hazardous Weather Outlook is for North and Central Texas.

.DAY ONE...Tonight.
Thunderstorm chances will begin increasing late this evening, with
widespread storms expected after midnight. Some storms across North
Texas will pose a threat for marginally severe hail in addition to
lightning and heavy rain.

.DAYS TWO THROUGH SEVEN...Saturday through Thursday.
Widespread thunderstorms will continue on Saturday. The severe
weather potential will be greatest roughly southeast of a Temple-to-
Athens line where a tornado or damaging wind threat may organize.
Storms across most of North and Central Texas will support a hail
threat throughout this time period as well. Thunderstorms will
generally taper off from west to east Saturday afternoon, although
isolated strong storms could linger into early evening.

After a brief reprieve from storm chances early in the week,
additional thunderstorms are possible on Wednesday and Thursday.

.SPOTTER INFORMATION STATEMENT...
Limited spotter activation may be requested tonight.
