Here is my weekly weather quiz question. What is “The Intertropical Convergence Zone?

_________________

An Upper Level High Pressure Ridge (“Arch “shape) is sitting right over us bringing sunshine and keeping overnight temperatures in the 20s. The graphics for days 1-3 show a frontal system offshore and moving down along the coast. The graphics for days 3-7 show more complex frontal activity moving our way Sunday through next Thursday returning the rain chances and raising overnight low temperatures..

Here is the correct answer.  The International Date Line is the line of longitude located at 180 degrees East or West (with a few local deviations) where the date changes by a day. West of the line it is one day later than east of the line.

Here is my weekly weather quiz question for the last time. What is “The International Date Line? Here is the correct answer.  The International Date Line is the line of longitude located at 180 degrees East or West (with a few local deviations) where the date changes by a day. West of the line it is one day later than east of the line.

An Upper Level Low Pressure Trough (“U “shape) moves in to return moisture and another frontal system. The graphics for days 1-3 show the frontal system moving southeastward through Northern California and away from the Pacific Northwest. The graphics for days 3-7 show more frontal activity moving our way Tuesday through next Saturday.
