Keeping A Close Eye On Midweek…

For the purpose of this post, we’ll focus on our next storm system that, at the very least, promises to deal more wet weather to central Indiana come Wednesday night into Friday.  Additionally, this will be a much cooler storm with temperatures struggling to get out of the 40s during the day Thursday, as gusty easterly winds reach 30+ MPH.  At the extreme, this could be another event that deposits widespread 2″+ rainfall totals across central Indiana…

The latest 7-day precipitation anomaly off this afternoon’s GEFS shows the wet pattern that will remain intact over the upcoming (7) day period.

The individual GFS ensemble members are truly concerning, especially given just how wet we currently are.  We note some members suggest additional 3″-4″ totals- with over 50% of that coming from our midweek storm.

We’ll keep a close eye on model data over the next couple of days, but as of now, we suggest planning for additional hefty rain totals in the Wednesday night through Friday time frame.  Also of interest will be the extreme cool associated with this storm.  As previously mentioned, the majority of the day Thursday will be spent in the 40s (more like early-March than early-May).  Factor in a gusty easterly breeze and we’ll have the makings for a truly “raw” weather day across the region.

More Heavy Rain And Storms Ahead; Cooler Week On Deck…

Highlights:

  • Widespread rain and strong storms today
  • Falling temperatures, windy, and wet Monday
  • Midweek storm brewing

Flooding Concerns Remain High…Another slug of moisture will lift north through central Indiana this afternoon into the nighttime hours.  Locally heavy rain will result in big flooding concerns as saturated soils are in place and many creeks and streams are already out of their banks.  Throw in an additional 1″-2″ with locally heavier totals and you have the makings of a dangerous flood situation into early week.  If that wasn’t enough to be concerned about, we’ll also have to watch how things evolve closely this afternoon for the potential of severe thunderstorms.  Damaging straight line winds are of greatest concern.

We’ll transition to a much cooler regime to open the new work week with gusty winds and showers continuing.  Temperatures will fall through the 50s during the day.  Jackets will be required!

Tuesday will provide a brief break from the wet weather and we should also introduce some sunshine for a while.  Unfortunately, we won’t have much time to dry out as a wet, windy, and chilly storm is brewing Wednesday evening into Thursday.  Widespread rain (some heavy) will combine with a raw easterly wind and temperatures in the 50s to lead to a rather miserable Thursday.

While shower chances remain early Friday, the theme heading into next weekend is a drier one and we should finally enjoy very pleasant weather by Saturday.

Upcoming 7-Day Precipitation Forecast:

  • Snowfall: 0.00″
  • Rainfall: 1.50″ – 3.00″
