For tomorrow, all sights will be set on a approaching cold front. With it, comes the threat of severe weather. There will be some pre-frontal and frontal storms. It looks like it will arrive in the afternoon hours, hang out overnight Friday and then taper off Saturday morning. This looks to bring us rainfall amounts between 1" upwards to 2" after this is all said and done. Can't rule out pockets of 2"-3" in certain parts of the state. SPC has placed ALL of Indiana under a Slight Risk for Severe T'Storms.
The main threats here will be straight line winds and large hail. Flooding from heavy downpours, and isolated tornados can be a concern as well.
As the Cold Front passes and the Jet Stream buckles down, we are looking at a much cooler and more pleasant & refreshing weekend ahead with some relief from the recent high humidity levels. Temperatures fall back into the low 70s. Some areas in the states may only record upper 60° high temps.
Next week starts off picture perfect. It will be dry and sunny with temperatures heading upwards to the low to mid 80s. Starting next Wednesday (12th), the average high temperatures falls below 80° and on the Sunday (9th) the average low falls below 60°. Temperatures aren't the only thing that goes down, so does the duration of daylight. We lose over an hour this month. When the sun rises later, this leaves less time for daytime heating thus temperatures go down.
After a dry May, June, and July totaling 3.62" of rain. The tables turned for a wet August and a early wet start to September. We picked up 6.51" last month and 1.98" in the first 5 days this month (thanks to Isaac). Current 2 month rainfall total sits at now 8.49". With increased reservoir levels and LOTS of Rain, this has prompted much of state to lift both their water and burn bans. This has eased the drought conditions and now NO COUNTIES in the state are under a Extreme Drought or Exceptional Drought. Now 100% is still abnormally dry. 88% is in Moderate Drought and nearly 55% is in Severe Drought including Indianapolis.
If you look below I have two images. The image on the left is the drought map that released back on August 7th at its worst. The image on the right is the drought map that was released this Thursday Morning (September 6th). You can see the big improvements in 30 days, red indicates the worst drought categories of Extreme and Exceptional. Yellow areas show little to no drought. Orange indicates Severe Drought and tan indicates Moderate Drought.
Also, I've compared burn ban maps as well. The image on the left is the burn ban map from June 29th. On the right is the burn ban map today. There is only 6 counties in Indiana still under a burn ban. They are:
Brown, Clarke, Crawford, Floyd, Martin, and Switzerland County.
