Model Data Remains Consistent On A More Active Pattern Returning…

Today’s 12z model suite is in and it remains consistent on a more active weather pattern returning to the delight of many Hoosiers! A blend of the GFS and European 10-day rainfall numbers print out 2″ for Indianapolis.  The GFS ensemble ‘mean’ (a blend of 21 individual members) agrees.

Best overall coverage of showers and thunderstorms should come in (3) waves over the upcoming 10-day period:

  • Wednesday into Thursday
  • Saturday into Sunday
  • Middle parts of the following week

While we don’t see any sort of uniform type rains in the upcoming period, the “smattering” of storms should help most neighborhoods get in on the rainy “goods” at one time or another over the upcoming week and a half.  Keep in mind, we’re in mid-June now and it’s mighty difficult to ask for anything much more than scattered storms this time of year on through late-summer…unless a tropical entity gets involved.  That’s just the way this time of year is.  With that said, localized torrential downpours are a very good bet from time to time, beginning as early as mid-week, as precipitable water values approach, or exceed, 2″ (about as moisture-rich as you can ask the air mass to get around these parts) into the upcoming weekend.

As I type this outside on the back porch this evening, I hear the sounds of sprinklers in full-force through the ‘hood.  Thankfully, Mother Nature will help save on the water bill later this week.  Longer-term, you’ll hear us use the word “transient” many times this summer when discussing the overall weather pattern.  Thankfully that tends to result in a fairly busy time of things.  Before you know it, college football season will be back (83 days until my beloved Auburn Tigers kick-off), those wetter autumn storms will return, and thoughts will begin to shift to winter (they may have already started here :-))- not that we’re trying to rush summer away or anything…

Developing Hot Pattern Doesn’t Last; Cooler And Wetter Times Loom…

Through the short-term, there are two words that will sum up Indiana’s weather: Dry and Hot.  We’re entering a stretch where the overall weather pattern will promote an expanding hot dome in the coming days, and put many communities across the state solidly in position to break the 90° mark on multiple days.

Expanding upper ridge means hot times loom late weekend into early next week.

However, this increasingly hot and dry pattern will be a transient one.  This morning’s European model shows the evolution to cooler and increasingly wet, unsettled times nicely as we progress into the 6-10 day period.

The GFS ensemble would also agree in the overall pattern shift back to cooler and unsettled conditions as early as mid-late next week.

The 10-day GEFS ‘mean’ is a beautiful sight as moisture returns.

Updated 7-day out later this afternoon!  Enjoy a beautiful Saturday, friends!

Dry Times Remain: Briefly Cooler Then The Heat Is On…

Our overall weather pattern will be dominated by short-term cooling, significant warming by the weekend, and dry times continuing.

We’re noticing a significant change to the brand of our air mass this evening as a northerly wind is taking hold and helping to usher in lower dew points.  This is only the beginning of a significantly cooler stretch of weather that will take us through the day Tuesday, continuing into Thursday.  While the upper level low will drift south into the Northeast, our region will be dominated by a northerly flow and a much cooler, refreshing air mass into the latter portions of the work week.

In fact, we forecast highs Wednesday to only top the upper 60s, and this will be a good 10°-15° below average for June 7th.  Lows each morning through Friday will start out in the lower-middle 50s for the city, itself, but some outlying neighborhoods will fall deep into the 40s.  Very refreshing, indeed, for early June!

High pressure will dominate our weather through late week, continuing the overall drier than normal theme.

Models slowly begin to increase moisture levels as we move into the weekend and an isolated shower or thunderstorm could develop, but widespread rains of significance aren’t anticipated for the foreseeable future.

The bigger story by the weekend will be a developing hot weather pattern.  Temperatures will be flirting with the 90° mark as early as Sunday and Monday.  Instead of running 10°-15° below normal such as midweek, temperatures by early next week will be running 5°-10° above normal and very much like the “heart” of summer.
