Another Pleasant Day – Dew

posted in: Michigan Weather Forecast | 8

We had a bit of mist and sprinkle overnight, enough to put .03 of an inch in the rain gauge.  One thing to keep in mind in regards to your rain gauge is to empty out any dew measurements it may have accumulated over night.  CoCoRaHS doesn’t need to know how much dew a location has, it doesn’t count as rain.  I have seen as much as a tenth of an inch collected overnight.

Dew is water in the form of droplets that appears on thin, exposed objects in the morning or evening due to condensation.  As the exposed surface cools by radiating its heat, atmospheric moisture condenses at a rate greater than that at which it can evaporate, resulting in the formation of water droplets.

When temperatures are low enough, dew takes the form of ice; this form is called frost.

Because dew is related to the temperature of surfaces, in late summer it forms most easily on surfaces that are not warmed by conducted heat from deep ground, such as grass, leaves, railings, car roofs, and bridges (and rain gauges).

Water vapor will condense into droplets depending on the temperature. The temperature at which droplets form is called the dew point. When surface temperature drops, eventually reaching the dew point, atmospheric water vapor condenses to form small droplets on the surface.


We had a high temp of 67° yesterday, a reminder that fall is here – however warmer air is in the forecast.  Today we should hit the low to mid 70s with clearing skies in the afternoon then the real warmth returns through much of the rest of the week with temps in the 80s though there will be daily chances of rain albeit low chances.

We will be headed to our annual pilgrimage to the Allegan County fair today to roam amongst the rest of the fair goers.  We don’t do the rides, we just gawk at all the people subjecting themselves to centrifugal forces with screams of fear and excitement.  We look at the animals, eat and check out the pavilions and barns.

According to Bill Stiffen the departure from average for the 1st 8 months this year has been -1.2° from the 30 year average. And of course there had only been one month (July) that has been warmer then average so far this year. (that may mean the late fall and next winter could be warmer then average?). And according to Bill there has been 30.47” of Precipitation so far this year although there has only been 0.21” so far this September. And so far this year Grand Rapids has had 44.2% of possible sunshine we should have had 50.6% at… Read more »

It has been a long time since I have been to a county fair. The last fair we went to was the Ionia free fair. But when I was a kid we went to many fairs in the last summer time. Three of the fairs we would never miss were the Midland county fair, The state fair in Detroit. Back then that was a huge fair with lots of entertainment and lots of things to look at and of course lots of rides. And the last fair we would always go to was the Saginaw fair and that fair at… Read more »
