#MEwx Sun, snow possible and telling the weather AFTER it's already rained

Good morning Augusta.

I’ve put up an Ambient WS 5000 weather station where you can view real time weather readings from my location online by clicking here.

This morning we have clouds and sun with a chance of snow, then snow this afternoon. Total snow accumulation of 1 to 3 inches. Highs in the lower 20s with light and variable winds.

Tonight we’ll have mostly cloudy conditions with a chance of snow this evening, then partly cloudy after midnight. Lows around 8°F. Winds will be light and variable.

We’ve didn’t receive any additional snow here over the past 24  hours.  

The  wind is North Northeast between  0.9 MPH and 3.8 MPH.

The Relative pressure is 29.81, the Absolute pressure is 29.61 and rising with a weather graphic indicating sun.

Augusta’s humidity is 86%, the  outdoor temperature is 3.7°F, the dew point is 0.5°F and the wind chill is 3.7°F.

Visibility is  10.0 Miles / 16.1 Kilometers with bright sun and a few clouds.

The UV index is 1 placing the average person at low risk and the solar radiation reading is 132.8W/m2. Sunrise is 6:23 AM, sunset is 5:23 PM, moonrise is 9:28 AM and Moonset is 12:01 AM. The moon is Waxing Crescent and is 38% illuminated. We’ll have 11 hours 01 minutes of daylight today. The next Full Moon is on March 9 with our next new moon being on March 21, 2023 .

 

How to tell the weather after it already rained.

 

“Rain before seven, clear before eleven.”

This proverb is actually more related to fog than rain, but it makes a handy little saying. The most common type of fog is called radiation fog, which occurs on clear, atmospherically stable nights. As we learned with the proverb about dew, heat from the ground radiates to outer space, cooling the ground to the dew-point temperature. This creates drew. As it cools even more, condensation is formed in the air through a process known as heat conduction. This occurrence is almost exclusively a nighttime and very early morning phenomenon.

 

In some cases, if the air has some turbulence, the fog can thicken and even produce rain. This isn’t rain from a low pressure system, though, meaning the vapor will soon be spent, and the rain will not last long. Hence, if there is rain early in the morning (before seven), it’s likely to clear off by lunchtime.

 

Note that this is only accurate for this type of fog-related shower. If it’s a true low pressure system, the rule does not apply.
