Hazardous Weather Outlook

This Hazardous Weather Outlook is for north Alabama and portions of
southern middle Tennessee.

.DAY ONE...Today and Tonight...

Numerous thunderstorms are forecast to affect the Tennessee Valley
today. Rainfall totals of around 2 inches over northwest Alabama
could result in flash flooding or areal flooding, especially those
areas that impacted by several rounds of heavy rainfall. Wind gusts
to 50 mph and frequent lightning is also possible with the stronger
storms. Thunderstorm chances will diminish from west to east this
evening, as an upper level system exits the region.

.DAYS TWO THROUGH SEVEN...Thursday through Tuesday...

Heat concerns return to the area on Thursday, continuing through
Saturday. Daytime high temperatures will peak into the mid 90s, with
Heat Index values from the upper 90s to excess of 105 degrees.

Residual moisture along with very warm to hot temperatures, will
result in mainly afternoon and early evening thunderstorms each
day. A frontal boundary approaching the region early next week, will
bring somewhat higher chances for thunderstorms next Monday through
Tuesday.

.SPOTTER CALL TO ACTION STATEMENT...

Activation of storm spotters and emergency management personnel is
not anticipated at this time.
