August 11, 2010: No changes in the forecast...

August 11, 2010

No significant changes from the previous few days. Our well forecasted heat wave continues to impact our area. Excessive heat warnings continue for our entire region. Heat index readings will once again reach into the 100s. Maximum temperatures will range from 98 to 104 degrees.

I recorded 103 degrees yesterday here at the Weather Observatory in Massac County. It felt every degree of that. Intense heat will once again be the main story for today and tomorrow across our region.

Remember that burn bans are currently in effect for portions of the region.  Fire departments are asking that you please don't burn fields or debris.  Dry conditions continue.

A cold front is forecast to approach and move through our region late in the weekend. This is going to bring our best chance at cooler weather and lower humidity levels. This is good news. However, a drought busting rain is not currently in the cards. There will be, however, an increased chance for showers and thunderstorms.

Next week should bring temperatures in the upper 80s to around 90. Lower dew points and humidity levels. This will make it feel even cooler. We will also watch for some thunderstorm complexes that may move in from the northwest. There is uncertainty on just how significant our chances for rain will be. So, stay tuned for updates on rain chances!

The National Hurricane Center has upgraded our disturbance in the Gulf of Mexico to a tropical depression. Some increase in intensity is possible. The big story is going to be gusty winds and rain along the Gulf of Mexico Coastline. This system is expected to move north/northeast into the Tennessee Valley over the weekend. This will at least help increase their chances for rain.

The tropical depression is currently forecast to increase our moisture levels just a bit ahead of the cold front moving into our region over the weekend. Although the main focus of the depression should remain to our south and east. Unfortunately.

Still some time for changes in the track - so I will keep a close eye on any future change that might occur. As of right now I do not believe we should get our hopes up on this depression impacting our immediate local counties.  Will also need to keep an eye on the track for flooding potential somewhere in the Tennessee Valley - perhaps as far north as southeast Kentucky.  They tend to flood quite easily during heavy rainfall events.  I will monitor and update accordingly (for those living in that region or for OEM).
