July 12, 2008: 5:35pm

We may see a little severe weather over parts of our area...

A severe thunderstorm watch has been issued for parts of the area through midnight EDT...

The watch does not include Louisville, but areas west of Louisville (see map)

Inside of this watch area, the SPC calls for the threat of up to baseball sized hail and winds up to 70mph...

Other probabilities for this watch:

Probability of 2 or more tornadoes
Low (20%)

Probability of 10 or more severe wind events
Mod (50%)

Probability of 10 or more severe hail events
Mod (50%)

Probability of 6 or more combined severe hail/wind events
High (80%)

Looking at the map, the line that is in front is the one that is severe at this time over western Kentucky/southern IL/MO...

The other line may go severe as well, but would not effect us...

Not sure if these storms will make it here severe, however, we are under a slight risk of severe for tonight...

If you're wondering how all these storms can sustain themselves while they are following each other, then here's the answer!!!

These storms have a constant flow of moisture from the Gulf of Mexico, which will help them not to die out. However, the storms in the front of the line steal the instability, which makes their severe nature die down a little. Nevertheless, these storms will survive unless their moisture flow is cut off.

That is why I don't think the line to the north will be severe...there is moisture in the atmosphere but they don't have a moisture flow...

Going into severe mode for the night...stay tuned for updates...

If you're wondering about the rest of the week:

It looks fine Sunday afternoon-Tuesday, with temps in the mid 80's and low humidities...

Wednesday-Saturday, however, the temps will be in the lower 90's and dewpoints in the 60's nearing 70 by Friday. A chance of storms will enter the picture beginning Thursday.
