The region has already dealt with a couple rounds of showers and thunderstorms this morning. Drier air will build in from west to east as we progress through late morning, but a cold front still sits to our northwest. It’s possible as this front drops southeast this afternoon that we deal with another round of thunderstorms.  Best storm chances appear to remain south and east of Indianapolis this afternoon, but we can’t rule out a scattered storm anywhere across central Indiana.  This front will help usher in another cool, dry air mass with much lower humidity for mid and late week.  Storm and rain chances will build over the weekend into early next week, but the big story next week will be the developing unseasonably cool air mass that will blast in here Tuesday (highs may not make it out of the 60s a day or two next week).

Monday Evening Video Update!

This evening’s video covers a potential round of thunderstorms Tuesday morning and takes a deeper look at the mid range.  Yet ANOTHER unseasonably cool blast of air awaits on deck for mid-month and will provide a hint of early fall, per the EC ensemble run below for next week.  This is just one piece of data amongst several pieces pointing towards a big mid-month cool down.  Much more in the video update below!

Here We Go Again…

What a weather year this has been for central Indiana.  Snow and cold translated to wet and stormy as winter turned to spring.  Now as summer rumbles into the supposed “dog days” we’re really left with the exact opposite.  Our weather pattern will be dominated by a fast moving northwest flow over the upcoming (7) days and this spells an active and stormy open to the work week and next weekend, with an “island” of cool, pleasant weather thrown in the mix Wednesday through Friday.

The GFS operational run shows that we’ll remain locked into the rather active northwest flow pattern through the upcoming week.  Note that while the trough axis moves east with time, the northwest flow remains intact.

There’s excellent ensemble support from the GEFS and EC, as well.

The end result is a (7) day stretch that remains cooler than normal when all added up, highlighted by the cooler punch of air (worthy of open windows yet again) Wed-Fri.

This also remains quite the active pattern in regards to thunderstorm complexes and rounds of locally heavy rainfall.  We bracket late tonight into Monday morning and again Monday night into Tuesday, followed by next weekend for possible storm complexes that will make for a rather noisy time of things here.  As for the severe threat, we’ll have to keep a close eye on each complex.  It’s possible one or two of these could pose a damaging wind threat as they race southeast and that’s our biggest concern as of now.

When you total it all up, the upcoming (7) day period, July 7th-14th, is likely to lead to more significant rainfall over the region.  The Canadian isn’t holding back, suggesting widespread 2-3″ totals.  That may be a bit “bullish,” but we’ll forecast 1.5″-2″ with ease during the upcoming week, including locally heavier totals.

Quick summary:

Monday through Tuesday will be highlighted by rainy and stormy periods before we introduce a much cooler and drier regime Wednesday through Friday.  Humidity builds over the upcoming weekend with additional rain and thunderstorm chances returning.

Happy Independence Day!  Canadian high pressure remains firmly in control of our weather today and for the majority of the weekend for that matter.  As a result, look for plentiful amounts of sunshine and temperatures that will continue the cooler than normal regime we enjoyed Thursday.  Today’s conditions, once again, will have that feeling of early fall.  ENJOY!  A more active weather pattern will return early next week as we potentially have to deal with a couple thunderstorm complexes in the Monday-Tuesday time period.  Heavy rain and the chance of severe weather will return to your forecast Monday night into Tuesday and we’ll have more details around this as we move closer.  A cooler and drier regime will build in by the middle portion of next week.
