An upper level low pressure system will sit over the Ohio Valley this week. This will give us a daily chance for scattered showers and thunderstorms.
The rain will also affect our temperatures and keep our highs in the upper 70s and low 80s through the weekend.
We have a severe thunderstorm watch for 15 counties over southern Indiana. The watch continues until 10:00 pm. We’ll have up to one inch of rain south of I-70, and the storms are bringing heavy rain and lightning to these areas.
What a difference a year makes. Last year we were in the middle of a drought and our rain deficit stood at 4.82″ below average. As we all know, things got much worse as the dryness continued throughout the summer. This year we have a 3.42″ moisture surplus.

We’ll have a slight chance for thunderstorms on Tuesday. Otherwise this will be a warm, humid week with a slight chance for isolated afternoon t-storms.
Highs will be in the 80s this week, and near 90 degrees this weekend with a stronger chance for storms.
We’ll have highs near 80 and lows near 60 through the weekend.
Our next chance of thunderstorms comes Saturday night and Sunday and continues into early next week.
Patchy fog is possible early Tuesday morning before we warm into the mid 80s. After a mild start to the year, our first 90-degree day will come Wednesday. The heat will spark a few t-storms and there is a slight risk for severe weather on Wednesday. Our severe weather threat grows Wednesday night into Thursday morning as a strong cold front moves closer.
By this time last year, Indianapolis had already sweated through three 90 degree days. This has been a milder spring and that trend will continue this weekend. Expect highs in the 70s with sunshine on Saturday and a chance for scattered thunderstorms late Sunday through Monday. Meanwhile, the remnants of Tropical Storm Andrea, our first tropical storm of the season, will move up the east coast causing flight delays in New England this weekend.
Northeast winds kept temperatures in the 60s on Monday and lows will dip into the 50s overnight. This will be a mild week for central Indiana with highs in the 70s. Dry conditions will prevail for the next 48 hours before more rain and thunderstorms arrive Thursday and Friday. As of now we are not expecting severe storms, but we’ll watch the next weather system carefully. For you allergy sufferers, the mid week rain may help a bit.
This will be a soggy weekend. Most of central Indiana is under a Flash Flood Watch and 1-3″ of rain is likely Saturday. We’ll have a slight risk for severe weather as a strong storm system moves across the state. The heavy rain ends Sunday morning.
