Dan, If the environmental lapse rate approaches the dry adiabatic lapse rate (3°/1000 ft), the air is indeed unstable. However, to get deep, moist convection, three things are usually needed. (1) Instability (2) Moisture (3) Some kind of outside energy contribution (or anything that creates...

Milton now has a central pressure of 897 mb or 26.49"! Just 24 hours prior the central pressure was 981 mb. That's 84 mb drop in just 24 hours.

Milton has increased to 180 mph as of the 4pm update which is a strong category 5 hurricane. Right now it is in a low shear environment over some very warm waters which has allowed it to quickly intensify. Fortunately, it is expected to gradually get into strong shear and dry air is expected to...

The way to look at this is the following... The TAF starts out with prevailing conditions which is the first line in the TAF right after the valid period (e.g., 3000/3034). If the weather is expected to change over the 24 or 30 hour valid period, you will see other forecast groups following the...

Just to note the BECMG was dropped more than two decades ago from appearing in TAFs issued by the NWS...it will appear in international and military TAFs.

I am glad to see you aren't discouraging learning how to use the Skew-T. When someone sends me an email asking for me to help them increase their weather knowledge so they can make better operational decisions and feel more confident, I often ask them if they want to learn how to use the...

I am excited to tell you that I recently released the soft cover version of The Skew-T log (p) and Me: A Primer for Pilots. A thermodynamic chart such as the Skew-T log (p) diagram is the best kept secret in aviation. This primer is the most comprehensive resource available for general aviation...
