Helene Strengthens..

* Helene has become the third major hurricane of the 2006 hurricane season...Max sustained winds are at 115 mph, minimum pressure is estimated at 962 millibars...

* The hurricane won't threaten the Gulf of Mexico, and is a longshot to threaten any part of the U.S. mainland. It will likely curve out to sea.

* STORMY MONDAY? We have a good shot at seeing some thunderstorms tomorrow...The Storm Prediction Center hasn't outlooked us for any severe weather, and our weather office is in complete agreement with that assessment. The air aloft is a bit too warm to support severe weather, 500 millibar temperatures are forecast to be around -5 to -7 tomorrow. -10 or lower temperatures would create a much more unstable airmass. That being written, we will likely deal with a few thunderstorms tomorrow, but they will stay below severe limits in most cases.

* A BIT COOLER: The front responsible for the thunderstorms will quickly push through Tuesday morning, ushering in a cooler and drier airmass. Highs Wednesday and Thursday will likely stay in the lower 80's with low humidity values...Not too bad for the last week of the calendar summer.
