Mild, overcast and Barometric pressure v. HPA.

Good morning Augusta.

This morning it is partly cloudy. High of 45F. Winds from the West at 5 to 10 mph.

Tonight it will be partly cloudy in the evening, then clear. Low of 19F. Winds from the NW at 5 to 15 mph.

The readings from my own weather instruments are:

The humidity is 89% with a Dew Point of 36ºF, Temp is 38.9ºF with a wind chil of 38.9ºF.

Our wind direction is Southeast between 1.5 MPH and  3.3 MPH.  

The Barometric pressure is 29.97 HPA 1014 and falling with a weather graphic indicating clouds.

The UV rating is 0 out of 16, Sunrise is at 6:54 a.m. sunset is 4:001 PM and Moon Rise is at 1:15 p.m. EDT and the moon phase is     waxing gibbous.

For the pilots out there Raw Metar is:

METAR KAUG 011153Z AUTO VRB05KT 10SM OVC095 04/02 A2992 RMK AO2 SLP137 60000 70002 T00390022 10044 20033 50006

Visibility is 10.0 miles / 16.1 kilometers with overcast conditions to 9500 ft / 2895 m.

We had 1.12 inches of snow melt in the past 24 hours.

What exactly 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.
