Partly cloudy morning

It is partly cloudy this morning which will become mostly cloudy during the afternoon hours. Today's temps should reach about 43ºF. We have wind that will increase to perhaps 15 mph later this afternoon.

Tonight it will be very cloudy with temps in the low 20's  to low 30's with chance of rain.

The readings outside right now are:

a relative humidity of 58% with a Dew Point of 30.9ºF.

The temperature is 44.3ºF, with no wind chill to speak of.

The wind velocity is presently between 7.0 mph and 14.1 mph out of the North.

Our Barometric pressure is 29.68 and rising.

Predicting Weather — Cloud Cover

If you want to use an old, and I mean OLD fashioned way to predict the weather, try reading the clouds to predict weather. You know, like the early American explorers or native Americans used to do every day.

You will improve your accuracy by learning about the types of clouds and how the wind affects the weather with each kind.

There are only three basic cloud formations: cirrus, stratus and cumulus.

Cirrus, From Latin, meaning "curled". These are high ice clouds in an otherwise clear sky, from 20,000 to 40,000 feet. You see them as feathery "mares' tails", long curling clouds that are the tops of thunderheads off beyond the horizon.

With cirrus clouds overhead:

If the wind is anywhere from the Northeast around through East to the South, you can expect rain in the next 24 hours.

If the wind is anywhere from the Southwest around through West to the North, good weather will remain another 24 hours.

Stratus, From Latin meaning "spread out". These are low clouds, a uniformly gray overcast from near ground level up to about 8,500 feet. They always predict unpleasant weather.

With stratus clouds overhead:

1) If the wind is from the Northeast around to the South, you can count on heavy rain in the next 24 hours.

2) If the wind direction is from any other direction, you can count on a continued overcast for the next 24 hours, with no rain or at the worst a slight drizzle.

3) If the cloud cover has a slightly billowing look, you have "strato-cumulus", clouds. This type of cloud allows you to predict immediate rain.

Cumulus, From Latin meaning "heap". These are low clouds at 1000 - 2000 feet, the heaped-up fluffy white clouds scattered in a blue sky.

With cumulus clouds overhead, it never rains, unless:

The wind shifts to the East, or,

The clouds build up into towering black clouds with winds from the West, forming the classic thunderheads sometimes shaped like an anvil (cumulo-nimbus clouds).

You can predict the weather for the next 24 hours with high accuracy if you keep these few facts in mind. There are two more cloud formations that you should know to complete your education.

Alto-cumulus. These are water and ice clouds, the "mackerel" sky, that looks like gently rolling waves in the ocean as seen from a low-flying airplane. You will see this kind of sky only a few times a year.

When you do:

With winds from the Northeast around to the South, they always mean rain within 24 hours.

With winds from any other direction, they mean just a continued steady overcast.

Alto-stratus. These produce a uniformly gray overcast, similar to stratus clouds, but higher and lighter. The sun looks as if you are seeing it through frosted glass. The weather prediction is the same as with alto-cumulus, but the precipitation will be here in ten to twenty hours, rather than in 24 hours.

So keep an eye on the wind and the clouds and amaze everyone with your uncanny meteorological predictions.
