Spotter activation is not anticipated through Thursday.
Well, our much anticipated relief from the heat has arrived. This is the first day we have not been under a heat advisory in more than a week. Although temperatures today will likely be in the upper 80s and lower 90s it will not feel as hot. Humidity levels are lower. This is good news. Your seven day forecast can be viewed here.
It will be cool enough tonight to sleep with the windows open.
Temperatures through the rest of the week will be in the upper 80s and lower 90s. Heat index values will range from 90 to 98 degrees. We may have to start think about heat index values of 100+ again by the weekend and into next week. The rest of the month is expected to have normal to slightly above normal temperatures.
What most people want to hear are the words "rain is on the way" - so, let's take a look at the potential for measurable rainfall over the coming days.
A slight chance for rain on Tuesday night and Wednesday as a disturbance passes near our region. Better chance of rain as you go north and west in Missouri and Illinois.
We will then have another chance of rain and storms late in the week as a frontal system approaches our region and mixes with some tropical moisture from a disturbance in the Gulf of Mexico. As we have been talking about for some time now - there could be a risk for heavy rainfall over portions of the Tennessee and Mississippi Valley late in the week. The exact track of the tropical disturbance is a bit uncertain. I will update as it becomes a bit more clear. Right now it appears portions of Arkansas, Louisiana, Mississippi, Alabama, and Tennessee would be the most likely area for heavy rainfall.
There is a small chance that the tropical system could push much further west than currently anticipated. Bottom line - as mentioned above - a lot of uncertainty on the track of the tropical disturbance.
Several locations in our region received rainfall over the weekend. Totals of 1-3" were reported over portions of southern Illinois and western Kentucky and Tennessee. Meanwhile, other areas received little or no precipitation. I recorded a total of 0.08" of rain since last Friday. Barely enough to wet the sidewalk. For the month I am now at 0.16". Dry - to say the least.
