Here again is my new weekly weather quiz question. One of the most important discoveries in modern Meteorology occurred during World War II. In 1944 our bombers taking part in the first raid on Japan had many of the planes run out of fuel much sooner than expected and many of them had to ditch in the ocean. What caused them to use up so much more fuel and later became one of the major tools in weather forecasting? Please post your answer as a comment after the forecasts on this page. The first person to post the correct answer will win a week of free personalized weather forecasts tailored to your needs. Good luck.

The upper air flow (yellow jet stream and dark colors for winds) shows a small high pressure ridge (“arch” shape in the yellow line) will give us a short period of drier weather through most of Friday. A trough of low pressure (“U” shape offshore) will quickly move behind the ridge pushing lots of moisture our way to set us up for some more wet weather. A new frontal system, still offshore will bring the rain back. A strong surface low pressure area will help spin more Pacific moisture our way.

The upper air flow (yellow jet stream and dark colors for winds) shows a small high pressure ridge (“arch” shape in the yellow line) will give us a short period of drier weather for today. A trough of low pressure (“U” shape offshore) will quickly move behind the ridge pushing lots of moisture our way to set us up for some more wet weather. More frontal systems (position shown Saturday) will be hitting Oregon over the weekend with a cooler air mass expected. This is good news for the ski resorts because the milder and rainy weather we have been having is being replaced with colder temperatures, falling snow levels, and new serious mountain snow accumulations.

Here is my new weekly weather quiz question. One of the most important discoveries in modern Meteorology occurred during World War II. In 1944 our bombers taking part in the first raid on Japan had many of the planes run out of fuel much sooner than expected and many of them had to ditch in the ocean. What caused them to use up so much more fuel and later became one of the major tools in weather forecasting? Please post your answer as a comment after the forecasts on this page. The first person to post the correct answer will win a week of free personalized weather forecasts tailored to your needs. Good luck.

The upper air flow is pushing lots of moisture our way to set us up for some more potentially heavy rain.  A cold front front is moving through the Pacific Northwest increasing the rain again as the warm front did on Saturday. More frontal systems will be hitting Oregon continuing into next week with a much cooler air mass expected for the new week. This would be good news for the ski resorts because of the milder and rainy weather we have been having will be replaced with colder temperatures, falling snow levels, and new serious mountain snow accumulations.
