Again, extra congratulation points if you can give the number of thunderstorms there per year.

More highs in the mid 90s today, but the workweek will cool off and hang around normal temperatures for the season.  An upper level low pressure (the little “U” shaped dip in the yellow jet stream line has moved Eastward with a high pressure ridge (“Arch” shape) right behind it. Heat from Eastern Oregon is being pushed our way and will continue to heat us up again today, but it won’t last very long. A weak upper level trough will dip our way along with a weak cold front from Canada (see blue line with triangles on it) to cool us back down, at least back to the 80s. We could certainly use some moisture, but it’s just not out there for us. There may be some thunderstorms, but they might even start fires in the forests.

An upper level trough of low pressure (the little “U” shaped dip in the yellow jet stream line has moved Eastward with a high pressure ridge (“Arch” shape) right behind it. I expected today to be quite warm in Eugene, but the morning clouds stuck around too long and the high pressure didn’t take over quickly enough.  Heat from Eastern Oregon will be pushed our way and will heat us up rapidly Saturday and Sunday, but it won’t last very long. A week upper level trough will dip our way along with a week cool front (blue line with triangles on it moving down from Canada) followed by more high pressure all of which means we’ll stay dry. We could certainly use the moisture, but it’s just not out there for us.

An upper level trough of low pressure (the little “U” shaped dip in the yellow jet stream line is moving Eastward with a high pressure ridge right behind it.  That means heat from Eastern Oregon will be pushed our way heating us up rapidly, but it won’t last very long. A cool front will slide in Sunday to cool us back down.

A high pressure ridge (the “arch” shape,  from the ocean into Canada, in the yellow line) will turn the onshore airflow to offshore and that means heat from Eastern Oregon will be pushed our way heating us up rapidly over the weekend, but it won’t last very long.
