No rain, Damp, its father's day and humidity explained

Good morning Augusta.

This morning it is partly cloudy. High of 73F. Breezy. Winds from the NNW at 15 to 20 mph.

Tonight it will be clear in the evening, then partly cloudy. Low of 50F. Winds from the NNW at 5 to 10 mph.

The readings from my own instruments are:

The humidity is 78% with a Dew Point of 56ºF and temp is 63.4ºF.

Our Wind direction is Northwest between 4.4 MPH and 9.1 MPH.  

Our Barometric pressure is  30.26 HPA 1014 and rising with a weather graphic indicating sun.

The UV rating is 1 out of 16, Sunrise will be 4:54 a.m. sunset will be 8:24 PM and Moon Rise is at 10:25 p.m. EDT with the moon phase being a Waning Gibbous.

For the pilots out there, Raw Metar readings are:

METAR KAUG 151153Z AUTO 33009KT 10SM SCT030 OVC090 16/13 A2993 RMK AO2 SLP135 60004 70004 T01610133 10161 20139 53021

Visibility is 10.0 miles/16.1 kilometers with Scattered clouds to 3,000 ft / 914 m, and overcast to 9,000 ft / 2,743 m.

WE received  no rain here in the past 24 hours.

Barometric pressure and HPA explained.

What is considered "Normal" barometric pressure?

What I found online to answer the question is that Normal barometric pressure at sea level is 29.92 inches of mercury. Any pressure reading higher is considered higher pressure than normal, anything lower is considered lower pressure.

In terms of meteorologists, low pressure that is significant is below 29.50" and above 30.50" is considered significant high pressure. 

Most everyone knows about Barometers and barometric pressure, but what does "HPA mean? When I post my weather readings I will post the barometric pressure in the same string as the HPA.

From an online source: hPa - Hectopascal Pressure Unit

Hectopascal is a 100x multiple of the Pascal which is the SI unit for pressure. The Hectopascal is the international unit for measuring atmospheric or barometric pressure. 1 Hectopascal equals 100 Pascals.

Due to its low value the Hectopascal is ideal for use as a measure of atmospheric pressure and other low gas pressures such as air flow differentials in air conditioning systems or wind tunnels.

One Hectopascal is exactly equal to One Millibar and although the scientific community has officially adopted the Hectopascal in preference to the Millibar, the Millibar is still used extensively throughout the world due to the proliferation of its use historically.
