Whether is a neutered goat or sheep. Most believe a combination of factors, from genetics to neurovascular imbalances in the brain, play a role.
One leading evolutionary theory is that getting a headache is a protective mechanism against adverse environmental stressors. The theory goes that headache pain would cause someone to seek a safer, more hospitable environment.
The fact that changes in weather and extremes in heat and cold cause headache, some experts believe, gives credence to this theory. They then were asked to rank them in terms of what commonly brought on their migraines and other headaches.
They also said they'd stayed away from places likely to have smoke in the air, such as restaurants or bars. As noted earlier, there is a theory that headaches triggered by extreme weather are a protective, or defensive, response because they lead the person to seek a more hospitable environment.
Experts believe that people who get frequent headaches have a greater sensitivity to changes in the environment. The reason, they suspect, is that people who get migraine headaches have likely inherited this sensitivity.
The survey cited earlier also found that two out of three headache sufferers had not discussed environmental triggers with their doctors. Some people have clear signs that a migraine headache is coming.
Some experts believe that people link their headaches to weather more than is actually true. That opinion is based on a 2004 study that analyzed patients' perceived headache patterns with actual National Weather Service data.
WebMD Medical News: Weather Behind Headaches, Sufferers Say.” Whether is a prime example of a word that will slip past the spell check.
Castrated ram or billy goat (according to A Word A Day). Weather, that stuff up there in the sky, is the ‘condition of the atmosphere with respect to heat or cold, calm or storm, etc’.
Interestingly, when it was first used in Old English in the 12th century, weather always had adverse implications. The frequently misspelled whether is used to introduce a question, often outlining a choice between options.
The farmer wondered whether the adverse weather had affected his whether. In this sentence, weather means to “withstand” or “survive” something that’s difficult or dangerous.
Used in the context of ships and storms, weather means to “come safely through”. I don’t know whether I should go to John’s leaving party or Mary’s baby shower.
In many sentences, the word “whether” could be replaced with “if”, though this doesn’t work well if there’s an “or not” immediately after “whether”. I don’t know if I should go to John’s leaving party or Mary’s baby shower.
If you find “whether” in a written piece, it’s almost certainly a simple typo (unless you’re reading a farming magazine). The words weather and “whether” are both in common use, though, and that’s why it’s easy for people to confuse them.

Check your local TV listings for exact time and station. Meteorological and aeronautical information is provided by continuous recorded Transcribed Weather Broadcasts (Web), the Pilot's Automatic Telephone Answering Service (Fatwas), and the Telephone Information Briefing Service (Ties).
Complete weather information is available by telephone call or visit to the nearest FAA Flight Service Station (FSS) or designated NOAA Weather Service Office. During periods of marginal weather, briefer are busy and telephone delays may occur.
Pilots may obtain Federal preflight weather briefings tailored to your individual needs. A standard briefing should normally be requested even when you have received prerecorded or mass media weather information (e.g., Web, A.M.
Adverse conditions whether VFR flight is not recommended* synopsis of prevailing weather systems current conditions' en route forecast destination forecast winds aloft Notices to Airmen (Notes)* any expected delays* any additional information the pilot requested. An abbreviated or standard briefing should then be obtained when closer to the time of departure.
During marginal VFR or IFR conditions, keep a particularly close check on en route, terminal and alternate airport weather. In-flight briefing procedures are explained in detail in the Airman's Information Manual.
Prior to descent, request current weather for the terminal area and conditions at your destination airport. At many airports, this information is continuously broadcast on Axis, ASOS, Amos, or selected navigation aids.
The last six hours of each period is covered by a categorical forecast indicating that VFR, MVR, IFR, or Life conditions are expected. Terminal forecasts are written in the following form: AIRPORT IDENTIFIER : 3 or 4 alphanumeric characters.
MESSAGE TYPE : RTD (Delayed), COR (Corrected), or AMD (Amended). CLOUD AMOUNT : CLR (Clear), Set (Scattered), BKN (Broken), PVC (Overcast), or X (Obscured).
Category Ceiling (feet) Visibility (miles) Life less than 500 and/or less than 1 IFR 500 to 1000 and/or 1 to 3 MVR 1000 through 3000 and/or 3 through 5 VFR more than 3000 and more than 5 EXAMPLE OF TERMINAL FORECAST: Scattered clouds at 1000 feet, ceiling 1800 feet broken, visibility 5 miles in light snow showers, surface wind 340 degrees at 15 knots, gusts to 25 knots.
Occasional ceiling 800 feet, sky obscured, visibility one-half mile in moderate snow showers. The categorical outlook for the last 6 hours beginning at 04Z calls for marginal VFR conditions due to ceiling.
Direction is relative to true north rounded to the nearest 10 degrees. Signets warn of hazardous conditions of importance to all aircraft i.e. severe icing or turbulence, dust storms, sandstorms, and volcanic ash.
Aires warn of less severe conditions which may be hazardous to some aircraft or pilots. Airmen bulletins are issued routinely and supplement the Area Forecast (FA).
CONVECTIVE Signets are issued hourly for thunderstorms in the continuous U.S. Center Weather Advisories, issued as needed, are detailed advisories of conditions which meet or approach Signet or Airmen criteria.

Severe turbulence below 6000 feet expected due to strong northwesterly flow behind a cold front. TRANSCRIBED WEATHER Broadcasts (Web) are continuous broadcasts of recorded COTAM and weather information prepared for a 50-nautical mile wide zone along a route and for selected terminal areas.
Webs are broadcast over selected NDB and VOR facilities and generally contain a weather synopsis, in-flight advisories, route and/or local vicinity forecasts. Winds Aloft Forecasts, current weather reports, Notes, and special notices.
PILOT'S AUTOMATIC TELEPHONE WEATHER ANSWERING SERVICE (Fatwas), and the TELEPHONE INFORMATION BRIEFING SERVICE (Ties), provide continuous recordings of weather and aeronautical information. The information may include area and/or route briefings, airspace procedures, and special announcements.
INTENSITY LightTurbulence that momentarily causes slight erratic changes in altitude and/or attitude (pitch, roll, yaw). * OR Turbulence that causes slight, rapid and somewhat rhythmic bumpiness without appreciable changes in altitude or attitude.
Report as Light Chop. Occupants may feel a slight strain against seat belts or shoulder straps. Food service many be conducted and little or no difficulty is encountered when walking. ModerateTurbulence that is similar to Light Turbulence but of greater intensity.
Changes in altitude and/or attitude occur but the aircraft remains in positive control at all times. Report as Moderate Chop. Occupants feel definite strains against seat belts or shoulder straps.
Food service and walking are impossible. ExtremeTurbulence in which the aircraft is violently tossed about and is practically impossible to control. * *High level turbulence (normally above 15,000 feet SL) not associated with cumuli form cloudiness, including thunderstorms, should be reported as CAT (Clear Air Turbulence) preceded by the appropriate intensity, or light or moderate chop.
NOTE: Pilots should report location(s), time (UTC or Z), intensity, whether in or near clouds, altitude, type of aircraft and when applicable, duration of turbulence.
