Ask the Meteorologist: Wind

ASK THE METEOROLOGIST “Where does wind come from?” Chase, Griffin Creek Elementary Winds are caused by differences in atmospheric pressure.  Areas of high and low pressure form when we have a lot of either warm or cold air in place.  Cold air is related to more stable, sinking air, and therefore is also related to … Continue reading »

High Pressure Takes Hold…For Now

WEATHER DISCUSSION We saw an active pattern towards the end of last week, bringing rain and some higher elevation snow.  Conditions started to improve by Sunday as high pressure began to build in, meaning a more stable, quiet pattern is on the way.  The next couple of days will be relatively inactive, but that will … Continue reading »

Right Back into an Active Pattern

WEATHER DISCUSSION Before the weekend arrived, models were suggesting that we would be getting a dominant ridge of high pressure and there was no end in sight. With high pressure, comes calm conditions with sunny skies. However, as is typical with forecast models. anything past a few days will likely change. So the monotonous days … Continue reading »

High Pressure Helps Weaken Next Front

WEATHER DISCUSSION A ridge of high pressure has built in over the west, and although the next storm system will weaken it, that ridge is exactly what keeps the front from making a big impact in southern Oregon and northern California.  By Sunday evening, showers will drift in with the cold front from the north, … Continue reading »

A Quiet, Pleasant Weekend Awaits

WEATHER DISCUSSION A ridge of high pressure has built over the western United States and pushed the jet stream well to our north.  That means the storm track is displaced northward as well.  So, we will look forward to a few quiet, less active days to end the weekend and start next week. A cold front … Continue reading »

Mainly Overnight Showers This Week

WEATHER DISCUSSION We still continue with our active weather pattern. Two systems approach the region this week, and both are looking to drop a little more rain. The first system, which will move in overnight tonight, will bring in light amounts of rain and the showers will be short-lived. Rainfall amounts for the first wave … Continue reading »

One More Warm Up, Before the Rain

WEATHER DISCUSSION The high pressure ridge is slowly making its way out of the region and before it leaves for good, we get one more round of roller coaster temperatures. Starting off with the overnight lows, we will drop to the 30’s east of the Cascades and in Northern California, the 40’s in the high … Continue reading »

One More Ridge Before the Rain

WEATHER DISCUSSION The rain pattern is moving closer to the region, but before it arrives, we will have to deal with one more ridge of high pressure. This one is quite a bit smaller than the one we had over the last two weeks. This smaller ridge will allow for skies to become mostly clear … Continue reading »

Fall Temperatures Within Sight

WEATHER DISCUSSION Although the marine layer has returned to coastal locations and substantially dropped temperatures, there was no relief from the unseasonable heat for inland locations.  Highs in the Rogue Valley were once again 10 – 15 degrees above average, and although it seems like the cool down will never come, I promise it is … Continue reading »
