Get ready for arguably the best weather day of the week on Sunday. Though it’s worth recapping that some areas received a good drink of water early Saturday morning.
Most locations along and north of I-70 had .70″ or more of rainfall… including nearly an inch and a half in Kokomo. For the meteorological summer (June 1-August 31), Indianapolis is roughly 1.50″ below average for precipitation.
A refreshing northerly wind, in the wake of the cold front that triggered rain, continues to blow across central Indiana. This dry flow ushers in much cooler air for Sunday.
As a result the Muggy Meter also drops well into the comfortable range (dewpoints <65°) Sunday morning… which means open the windows and enjoy some fresh air.
Also enjoy some of nature’s air conditioning with lows in the 50s tonight.
Though cooler than Saturday, the dry air will respond quickly to abundant sunshine the first half of Sunday… with highs eventually climbing into the middle 70s. If you chose Sunday to visit the Indiana State Fair you picked a winner! Expect a cool start followed by a mild temps, with scattered clouds and a steady breeze to finish.
That breeze will approach 20mph by late afternoon during peak heating… these late day winds are called “thermals” because of the lift created by surface heating on sufficiently bright days.
Underneath high pressure Monday will be a clear, cool and comfortable location. Once again we’ll start out the morning in the 50s, with a relatively dry air mass and ample sunshine.
At this point computer model guidance varies a great deal on timing of our next upper impulse embeeded within the persistent upper level northwest flow. So my confidence on precip chances late Monday are low, until I see better consensus in output. But know that there is at least a “chance” of rain/storms arriving Monday afternoon into Tuesday.
Confidence is higher during the middle of the week… with multiple model outputs showing a stormy set up over the southern Great Lakes/Ohio Valley region Wednesday. Some of these storms could be strong to severe, so we’ll need to monitor this closely in the days ahead. Have a great evening and thanks for reading the blog – Sean Ash
