Here is my new weekly weather quiz question. What are “Instrument Flight Rules (IFR)?

_________________

An Upper Level High Pressure Ridge  (“Arch” shape) is slowly warming up the Pacific Northwest. There will be frontal activity returning by Friday, but not of the bitter cold airflow nature. The graphics for days 1-3 show our next frontal system moving in Friday. The graphics for days 3-7 show more frontal activity moving our way Sunday through Thursday.

NOTE:

HERE ARE YOUR GROUNDHOG DAY REPORTS FROM AROUND THE COUNTRY – FEBRUARY 2, 2023.

1) Punxsutawney Phil, PA ———- Shadow.. 6 more weeks of Winter
2) Buckeye Chuck, OH ————– Shadow…6 more weeks of Winter
3) General Lee, ATL,GA ————- No Shadow… Early Spring
4) Staten Island Chuck, NYC ——- No Shadow… Early Spring
5) Sir Walter Wally, NC ——————No Report….. Retired
6) Snerd (Wally’s Replacement) —- Shadow.. 6 more weeks of Winter
7) Sun Prairie Jimmy, WI ————Shadow.. 6 more weeks of Winter
8) Dunkirk Dave, NY —————– No Shadow…Early Spring
9) Mal Verne Mel (Long Island, NY)-No Shadow… Early Spring
10) Holtsville Hal (Long Island, NY)-Shadow.. 6 more weeks of Winter
11) Spencer Butte Bob, OR ————Shadow.. 6 more weeks of Winter*
Results:: 4 No Shadow, 6 Saw Shadow, 1 no report = 6 more weeks of winter.
*My own groundhog “Spencer Butte Bob” saw his shadow for 6 more weeks of Winter. If this is Winter weather now I don’t think we will mind it so much.
Just remember that this is for fun and has no basis in Meteorology.

Here is my weekly weather quiz question for the last time. What is “Instability“? Here is the correct answer. Instability (abbrev. INSTBY)- is the tendency for air parcels to accelerate when they are displaced from their original position; especially, the tendency to accelerate upward after being lifted. Instability is a prerequisite for severe weather – the greater the instability, the greater the potential for severe thunderstorms.

_________________

A very strong Jet Stream flow www.wunderground.com/maps/wind/jet-stream  from the northeast is sending much cooler air to the Pacific Northwest. A strong cold front www.wpc.ncep.noaa.gov  pushed through the Pacific Northwest from the northeast (called a backdoor cold front) bringing colder air with it. It will take a while for temperatures to warm back up again.
