Solar Eclipse Effects on Mondays Weather

 

annular-solar-eclipse-promo

We are now in Kokomo, Indiana on our  way to Bowling Green Kentucky. Once we got in southern Michigan the sun was out and the temperatures were in the upper 70’s, At this time there are some showers to the west of Kokomo.  If the weather is good (not too cloudy) we have a spot for me and my wife it the small town of Franklin Kentucky. The spot is just inside of Kentucky just north of the Tennessee state line (less than 500 feet that is how close)
On this post I am going to over some of the effects that the eclipse could have on the weather where the eclipse is total and to a lesser effect here in Michigan where it will be a partial eclipse. With this eclipse happing during the mid-day time frame one of the biggest effects will be a midday drop in temperatures I would expect a 12 to 15° drop where I will be at (could be up to 20°) and maybe a 5° or more drop here in Grand Rapids. A lot depends on what the DP and wind speed are. Where the eclipse is total there should be a drop in wind speeds and a change in the wind direction as well. There have been some reports of a outflow boundary setting up that will be one of the events I will be look for. (that should not happen here) There is some research from a partial eclipse in England on March 20th 2015. In that partial eclipse the temperatures dropped around 5°C While I estimated a rather large drop in temperatures it may not be that great as it will be more humid here than it was in England in March. As for the wind we shall see. I would not expect much wind here in Michigan nor in Kentucky and for the outflow that may more likely in the total area than here in Michigan. During this eclipse, the University of Missouri will use grants from NASA to study the sudden temperature shifts. And I will let you know what if any changes I see,  I have a thermometer in the car and will also take one with me, but remember I will be in the sun so the readings will be on the high side before the eclipse becomes total. At this time the guess for Franklin for Monday is partly cloudy and a 20% chance of showers with a high in the low 90’s

MOSTLY SUNNY. HIGHS IN THE UPPER 80S. SOUTHEAST WINDS

If anyone is unable to drive to see this one (like me), you’ll only need to drive to Cleveland for next one on April 8, 2024.

Looking forward to that one as well! It will be almost twice as long as Mondays eclipse, almost 5 minutes compared to about 2 and a half minutes for this years eclipse. The down side of the 2024 one would be the time of year being in early Spring, which… Read more »

Yeah – but assuming you’re only talking Lake Effect cloudiness (I know – that’s a real cr@pshoot) – you don’t have to drive far to escape it!
