Category: Severe Weather

Forecast period: 09.02.19 through 09.09.19

7-Day Precipitation: Precipitation is expected to run well below normal through the forecast period.

7-Day Temperatures: Temperatures are expected to run below average through the forecast period overall.

Severe Weather Outlook: In what will be a quiet period, overall, we’ll keep an eye to our north Tuesday evening. The reason? A cold front will push south and a line of strong to severe thunderstorms is expected to develop across northern Indiana tomorrow evening. Damaging wind is the greatest concern with storms across northern parts of the state. As the front continues to settle south, thunderstorms will weaken as they push into central Indiana between 8p and midnight. Otherwise, severe weather isn’t expected through the period.

Summary: The upcoming 7-days will be dominated by an overall cooler and drier than normal theme than we’d come to normally expect for early September. A couple of cold fronts will sweep through the state this week: Tuesday night and again Saturday. While there isn’t a lot of fanfare expected with these fronts from a precipitation perspective, they will serve to offer up a true fall-like feel mid week into the weekend. We’ll keep an eye on thunderstorms across northern IN Tuesday PM, but still expect these to be in a weakening state as they arrive into central parts of the state tomorrow night.

Forecast period: 08.18.19 through 08.25.19

7-Day Precipitation: Rainfall is expected to run near average through the forecast period. We’re forecasting widespread 0.50″ to 1″ amounts to be common across central Indiana, but there will be locally heavier amounts where strong storms track.

7-Day Temperature Outlook: Temperatures are expected to run near average through the forecast period- balanced by a warmer than normal open to the period and cooler than average close.

Severe Weather Outlook: An active weather pattern will remain with us through the 1st half of the new week. In addition to the threat of severe weather today, we’re also closely monitoring the potential of strong to severe storms Tuesday night-Wednesday as a cold front slices into the hot and humid air mass in place. The pattern will turn much calmer once we get to the 2nd half of the week as cooler, drier air builds in.

Day 1: After a quiet start to our Sunday, a line of thunderstorms is expected to form to our northwest this afternoon. That line should move southeast and begin to impact central Indiana late afternoon into the early evening hours. Some of the stronger cells will promote the chance of large hail and damaging straight line winds.

Day 3: Scattered thunderstorms will remain in the forecast Monday, but widespread severe weather isn’t anticipated. As we look ahead, a cold front will slice into the hot and humid air mass in place across the Ohio Valley Tuesday night into Wednesday. As you might expect, the clash of air masses between significantly cooler and drier air behind the boundary will lead to scattered to numerous storms during the transition. Accordingly, we’ll need to remain on guard for the threat of additional severe weather (threats similar to that of today) during that time frame before much quieter, calmer weather takes over Wednesday night into next weekend.

Forecast period: 08.12.19 through 08.19.19

7-Day Precipitation: Rainfall is expected to run near average through the forecast period.

7-Day Temperatures: Temperatures are expected to run near seasonal levels through the period.

Severe Outlook: Severe weather is expected across central Indiana as we open the work week. All modes of severe weather are possible including large hail, damaging winds, and a couple of tornadoes.

Summary: The forecast period will open up on an active note as a rather potent surface wave scoots across the southern Great Lakes region. A complex of thunderstorms is expected to organize across IA and IL Monday afternoon before pushing east southeast Monday evening. Accordingly, chances of strong to severe thunderstorms along with locally heavy rain will be on the increase Monday evening into very early Tuesday across central Indiana, including Indianapolis. Several favorable ingredients are coming together to produce the threat of severe weather, including large hail, damaging wind, and potentially a couple of tornadoes. On average, between 0.50″ and 1″ of rain is expected with this system, however, if thunderstorms “train” over the same communities tomorrow night, amounts will be much higher in localized areas.

Thereafter, weather conditions will quiet down as we move into the middle and latter portions of the work week. While heat and humidity will build to our southwest, immediate central Indiana shouldn’t have to deal with much in the way of excessive heat/ humidity through the forecast period with seasonal temperatures expected around our part of the state much of the week.
