Season’s first heat wave won’t last too long

When you factor in the dew point it will feel like the 90s today...

If we are ever going to hit 90 degrees this summer it is pretty much now or never.  Today I think we have a chance of hitting 90°, but the best chances for hitting it will be on Monday and Tuesday of this week.  We do have some changes to the forecast with us now tracking rain arriving along a cool front for late Tuesday and Wednesday.  The rain and clouds that will be around Tuesday night into Wednesday will likely put 90 out of reach on Wednesday.


Highs today will be close to 90

Highs today will be close to 90

The ridge will continue to strengthen as we head into the afternoon hours with the potential for an isolated shower or storm across the state.  Nearly all will be dry today with storms potentially firing along the Ohio-Indiana border and drifting east.  This would be along the weak boundary that has been responsible for our heavy rain days over the past couple of days.  While isolated storms could bring heavy rain in brief rounds for us, the more sustained rain potential will move out of the state today.

Similar to yesterday our highs will hit the upper 80s.  Yesterday when it became clear that skies would be mostly clear for a big chunk of the day I bumped up temps to 88 degrees and today’s weather should be similar to that.  Yesterday’s official high at the Indianapolis airport was 88° by the way.  The airport also recorded .81 inches of rain yesterday sending the monthly total to just 1.88 inches of rain.  This puts us at about a half inch behind the average monthly pace for August.  I think the four fifths of rain we received yesterday will be enough to keep our temperatures in the upper 80s today.  It is also helping fog formation first thing this morning.

Finally skies will be partly to mostly cloudy (breaking skies) with light winds out of the southeast.  Today will be the most humid day of the year so far with the dew point in Indianapolis potentially hitting 75 degrees!  Hopefully you can find a pool to stay cool.

Mini Heat Wave:


What just a couple of days ago was looking like an extended round of heat is now just going to be a small burst.  An upper low has now begun to move east from the northwest corridor and will track over Ontario, Canada from Tuesday through at least Friday.  The upper low is projected to push in a weak cool front on Tuesday afternoon that will bring with it a chance for rain.  I think we will still have a chance at hitting 90 on Tuesday ahead of the clouds and rain chance.  I think Wednesday though will be cooler with us seeing a very low chance of hitting 90.  I’ve actually dropped the Wednesday forecast high temperature to the mid-80s due to the weak front being around.  Another ridge may build as we head into next weekend potentially giving us another late season chance of hitting 90°

I expect that we will see parts of our area seeing a heat advisory either Monday or Tuesday of this week.  The forecast is calling for highs in the low 90s for most of our area.  You factor that in with the high dew points and it certainly will be possible to see some advisories issued.  In fact we are seeing places just west of the state heat advisories issued for today.  Have a great day!
