weather

When the adiabatic lapse rate becomes warmer than the environmental lapse rate at, say, 5000 feet, is that the point where an uplifting force is no longer necessary? My understanding is that below 5000 feet, the air remains stable, so an uplifting force is needed to reach that altitude. Once at...

Hi all! First post here as a new student pilot. Please help me understand this TAF… TAF KRIC 292340Z 3000/3024 05006KT P6SM VCSH BKN070 FM300300 05004KT P6SM VCSH SCT008 OVC015 TEMPO 3003/3005 BKN008 FM300700 06004KT P6SM OVC006 FM301700 06007KT P6SM VCSH OVC015 I understand the first line...

I know I'm just absolutely loving it. - Btw vacation and this crap wx I haven't been able to fly the plane since 12/26 - At ORD this morning and after 4 delays totaling a prospective 7h wait, I'm urged to rebook since the flight may get cancelled on account of arctic blast wx. Soonest I can get...

Hello, I'm a fairly new PPL and was looking for better weather resources than the usual ones. Before a flight I get my outlook and standard briefings from 1800wxbrief and/or ForeFlight like a good pilot, and they're great for short-range, especially ForeFlight, but they aren't as great for...

I never fly near weather that looks like this so I've never felt a need to dig into the symbols. But I've also grown tired of my ignorance in not knowing what they mean... With that prelude out of the way, can anyone elaborate on what these highlighted icons mean and the numbers? Numbers: e.g...

Hi All - In the Keys this weekend on vacation. Been watching TS Nicole which looks poised to hit FL on Thursday. My return flight to the Northeast is planned for Saturday. Obviously everything is very much in flux, but any general advice for flight planning around what seems like it will...

I like the aviationweather.gov weather details and it's my first stop when looking for pre-flight. The one chart I can't understand is the LLWS chart as part of the GFA tool. I get it that the further to the right in the color scale is "bad", but can anyone explain what these numbers mean?

I'm a 53 year old instrument pilot working on commercial and am very respectful of weather and its hazards. Does anyone have experience using an online weather/meteorology course to learn about weather from top to bottom. I want something beyond the content in the FAA publications. I'm...

I've been trying to leave Pittsburgh for 3 days to get back home to Chicago (I've been on a solo vacation), but as a non-instrument pilot I've had to continually push it back due to low ceilings and other issues on the en-route path. It's been more than a little frustrating as I constantly watch...

Hi All, I fly in the east coast of Canada and you can count on the forecast containing icing 7 months a year. I'm wondering how 'good' the various de-ice equipment actually is in practice on the various types of aircraft. For those of you who actually have de-ice equipment on your planes...

I have a XC trip that I am planning to fly in two weeks. I looked today at a 14 Day Forecasts, and different websites are saying different things. For example, one website says it's supposed to be clear and sunny on the day, and the other one says it's going to be rainy and cloudy. So, how...

Just...wow.

Low time PPL, there is once aspect of wind effect i am still not able to fully understand. This question can also serve as a refresher to other private pilots. The scenario is as follows: I am taking off in a relatively windy/gust day say 13knots/G20 knots, after rolling out and during the climb...

I have a few questions related to projecting de-icing/anti-icing costs for Pilatus PC-12s and King Air 350s. I apologize if some of these are a bit basic... 1) I know de-icing/anti-icing is most commonly done shortly before takeoff, but is there ever a need for it at other times while the...

I'm curious what website or service folks use when they want to get a sense of an airport's typical temperature and precipitation at a certain time of the year. For example, what are the average daily high/low temperatures and monthly precipitation for, say, an average February for an airport...

The question in question basically states that mountain wave turbulence is most dangerous to an aircraft downwind of the mountain flying into the wind.. I understand the downwind part, that's where the turbulence is. I don't understand how the headwind is any more dangerous than a tailwind though.

I'm having trouble understanding why wind shear occurs in areas of temperature inversion. I've been out on calm nights where I could see a layer of fog/smog which indicated a possible inversion.It is very calm aloft but when coming in for landing, it gets pretty bumpy sometimes. Can someone...

Came across a pretty cool capability to receive TAF's & METAR's by text message on a cell phone. Just text the METAR and the airports ICAO code and a couple of seconds later the data is returned. Phone Number and Directions for use...

The best time of day for me is after work which is 17:00-19:00. We always seem to have bad weather. I have flown about 2 out of my last 10 scheduled classes. It's been very frustrating. We're at 2200 MSL, so I guess I should have figured out the weather patterns beforehand :-). At 2.5 hrs...
