Then shifting the focus to Thursday, most of the day should stay dry under a mixture of some clouds and little sunshine with only isolated chances for storms throughtout the day but it looks like two air masses will collide. This means we could be looking at more strong to severe storms for Thursday Night into Friday Morning for much of the state. Following this, the PNA will go positive which means this will bring a big weekend cool down for the eastern half of the country. Indy Temps will fall into the upper 70s to low 80s for Friday-Monday. Then by Next Tuesday, we could start to warm back up towards the 90s again. I will monitor this pattern shift but it looks brief.
| SUN | MON | TUES | WED | THURS | FRI | SAT | |
|---|---|---|---|---|---|---|---|
| High Temp | 91 | 91 | 95 | 91 | 97 | 93 | 94 |
| Low Temp | 62 | 69 | 72 | 65 | 62 | 73 | 74 |
| Precip | NONE | NONE | TRACE | NONE | NONE | NONE | 0.25" | Peak Wind Gust (MPH) | 20 | 17 | 40 | 26 | 18 | 23 | 44 |
The average high for last week was 93.1° while the avg low was 68.1°. This puts the weeks avg temp at 80.6°.
Drought Analysis
After a very persistent dry pattern for May, June, & July we are starting to see some relief as we begin the second week of August. Some much needed systems moved through this weekend and brought a total 1.51" of rain for Saturday and Sunday. This is the most rain seen since May 1st.Unfortunately, as I been mentioning in previous blogs, it will take more than a one-two days of a heavy soaker to replenish the soils and grass sufficently. Nearly 25% of the State, mostly in Southwestern Indiana, is in an Exceptional Drought (highest drought category), while 85% is in Severe Drought or higher. These weekend storms only put a hold on the drought worsening. I expect very little change to the drought map once the information is put together tomorrow and released Thursday. We are however, showing little improvement here and there. We've knocked down our deficit in Indiana from over 10" down to less than 9.5". Here's the updated deficit chart.

If you do the math (well...I've done it for you) than you can see we've picked up 5.13" since May 1st, 2.43" since June 1st, 1.60" since July 1st, and 1.51" since August 1st. We've only had 15 out of the past 97 days with measurable rainfall. Measurable Rainfall is anything 0.01" or higher (Trace Amounts aren't measurable).
As the dog days of summer begin to come to a close by the end of the week we'll start to see a mix between 80° and 90° high temps to finish the month. We are now in the late beginning part of the month approaching mid-month and the summer season is almost over. Usually the heat does continue to hold on during August but its not uncommon to get brief interruptions of cooler air as the weather pattern starts to change seasons. When we get to the latter part of the year these frontal passages (FROPA) have a little bit of a teeth to it. FROPA is associated with a shift in the wind direction, from South to North, and ushers in cooler temps. As mentioned earlier we could expect an upper 70° high temperature reading. Something that hasn't been achieved since June 6th when Spring was transitioning into Summer. This will be a short teaser for the time being. I will continue to monitor the long range but part of the reason why we will get a brief relief from the heat this next weekend not only because of the time of the year but also has to due with Tropical Storm Ernesto down South. This system is taking a western track which will have little impact on the weather pattern in the U.S. We'll have a ridge holding back towards the Rockies and keeping the hot temperatures west, while a trough will be East bringing cooler, unsettled weather from the mid west towards the east coast.
