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″

Gearing Up For The “2nd Half…”

Central Indiana has enjoyed a well deserved break in the rain and thunderstorms this afternoon, but, unfortunately, stormy times will return tonight.  With an increasingly moist air mass in place (warm front is currently draped across central IN and slowly lifting north), renewed heavy rain is expected tonight into Sunday.  Dew points will approach 70° and precipitable water values (PWATs) will periodically reach 2″ between this evening and Sunday night.  With that kind of moisture content in the atmosphere, locally heavy, flash flood-producing, rains are a “lock.”  Should you live near a creek, stream, or river, please keep abreast of water levels into early next week and have a plan in place to move to higher ground.

The Storm Prediction Center paints a “Slight Risk” of severe weather across central and southern Indiana tonight.

We think an eastward-advancing line of thunderstorms will blow into central Indiana later this evening (between 9p and midnight).  Some of these may reach strong to severe levels with damaging straight line winds of greatest concern.  Additionally, torrential downpours will occur within this line of storms.

Overall coverage of rain and thunderstorms should diminish Sunday morning before ramping up and increasing in overall coverage and intensity (yet again) Sunday evening and night.  In fact, we may be looking at another severe weather episode Sunday night- again with straight line damaging winds of greatest concern.  By the time all is said and done we expect an additional 1″-2″ of rain across central Indiana with locally heavier 3″+ amounts where storms train over the same area.  Obviously, with saturated soils in place across central Indiana, this amount of rain will create flood concerns into Monday morning.  By the time we get to Monday, the big weather story will be strong and gusty NW winds, much cooler air (falling temperatures through the 50s) and nuisance-level showers.

Another heavy rain maker looms Thursday and we’ll cover that in our updated 7-day later tonight or Sunday.

Busy Weather Pattern…

Highlights:

  • AM showers then cooler and windy
  • Stormy weekend ahead
  • Cooler next week

Busy Times In The Weather Office…A cold front will sweep through the state this morning with lingering showers and an abrupt wind shift.  Gusty westerly winds and cooler air (we’ve already seen our high for the day) will be with us this afternoon, along with a variably cloudy sky.

Unfortunately, we don’t have many changes to the ongoing idea of hefty weekend rains.  A warm front will begin to slowly lift north Friday into Saturday and this will be the focal point for heavy rain and thunderstorms.  Overall coverage and intensity of rain and thunderstorms will increase as we rumble through the second half of Friday.  A couple of storms could be strong to severe- especially across southern Indiana Friday afternoon and night.

The aforementioned warm front will lift north and be located across the southern Great Lakes region Sunday.  This will put our neck of the woods squarely into the warm and humid air mass Sunday.  Though storm coverage will likely be more scattered in nature when compared to Saturday, heavy thunderstorms will develop, especially during the afternoon and evening hours.  With a deep-rooted tropical connection along with saturated soils in place from early weekend rains, flood and flash flood potential will be high as we go into early portions of next week.

As we open up the work week, we’ll shift gears from a moisture-rich southerly flow to one that’s out of the northwest and much cooler.  Showers will continue through Monday.  Our next storm system will then set it’s eyes on the region by the middle of next week.

Upcoming 7-Day Precipitation Forecast:

  • Snowfall: 0.00″
  • Rainfall: 2.50″ – 3.50″
