Cumulus Humilis: A Fair Weather Cloudscape
The dawn brought clear sky But, in a few hours, the warm sun would break the morning chill, and by mid-morning the perfectly clear sky would begin to lose its fair complexion as small buds of whiteness pop up hither and yon. So started a day when cumulus humilis, the most basic of the cumulus cloud family, would fill the skyscape. This cloud type often is the forerunner to larger, more developed cumulus varieties that fill the afternoon sky. But today, these fair-weather cumuli dot the sky within the large high-pressure cell that sat over the region.

How Do Clouds Float?
A frequent question we meteorologists get is: "If water drops are heavier than air, why do clouds float?" With lovely forms of cumulus clouds popping up all around me on this summer's day, that is the question I will tackle this month.

Why Is It Coldest After Dawn?
A common adage expresses the belief that it is coldest just before dawn and begins to warm with the appearance of dawn's first light, but observations and physical theory show us that the coldest hour of the day is not before dawn but often an hour or so after sunrise. Why is this so?

A Record Setting Day
For those who love weather in all its varied forms, extreme or rare weather events often hold great allure. Spawned by our love of statistics, one extreme event that catches our attention is the breaking of daily temperature records. Whether a record hot day or record cold day, it is sure make local news headlines. If today's weather set a record for either maximum or minimum temperature, you would likely respond with a modicum of interest. If I told you that this day broke both the daily maximum and minimum temperature record, you might exhibit degree of incredulity. I call such days: double record days.

Superior Moisture Gain
Large water bodies have major influences on the weather,impacting the weather and climate of their shoreline regions. But unless we are involved with the maritime industry or sport sailing, we tend to overlook the weather and climate over the water body itself. Herein, we look specifically at one aspect: on-lake condensation on Lake Superior.

The Flavour of Lows
Often in the weather reports we hear of tropical lows, subtropical lows, extratropical lows, and thermal lows. What distinguishes these various flavours of "lows" from one another?

Why Are Lightning Bolts Not Straight?
If you've ever watched a spark of static electricity jump from an object like a doorknob to your finger, you perhaps noted that mini-bolt followed a fairly straight-line path from the object to your finger. Lightning bolts are essentially the granddaddy version of that static spark, so why do lightning bolts generally appear so jagged and forked? The answer for lightning's jaggedness arises in its size and formation process.

Laying Some Groundwork-2: Humidity
Today's groundwork background topic looks at humidity, and from the questions I have received over the years, there seems to be a lot of confusion about humidity.

The Fog Rises
Fog is actually a cloud formed or lying on the ground -- even those patchy fogs which fill low spots or hollows in the terrain. Radiation fog forms when the air near the surface cools to its saturation temperature due to nocturnal radiation cooling.
