Mild Fall Weather Continues as California Expands Storm Tracking

Unseasonably warm and dry weather conditions are expected to persist through the weekend in many areas, bringing sunny skies and comfortable afternoon temperatures. Residents are enjoying a stretch of calm weather that has kept heating and air conditioning costs low, though dry conditions remain a concern. Afternoon temperatures are forecasted to reach the upper 70s to around 80 degrees, providing ideal conditions for outdoor autumn activities.

Looking ahead to next week, a weather system in the West will eventually shift toward the central part of the country, bringing increased cloud cover but minimal rainfall. Forecasters note that temperatures will likely stay above normal through much of the week, with a more active weather pattern potentially returning by Halloween weekend. Early projections for trick-or-treating suggest mild daytime temperatures giving way to evening conditions in the 50s, accompanied by clouds and a possible chance of showers.

Meanwhile, in California, recent scattered showers and thunderstorms have delivered beneficial rainfall to various regions across the state. Meteorologists have been tracking precipitation totals following these storms, while residents in Tracy captured footage of a rare funnel cloud.

To better understand and forecast these powerful weather events, Shasta College in Shasta County has become the home of a new weather balloon launch site. The location is the northernmost launch site established for the Center for Western Weather and Water Extremes (CW3E) at UC San Diego's Scripps Institution of Oceanography, designed specifically to help track atmospheric rivers.

Researchers explained that the new installation addresses a significant observation gap in Northern California, particularly around the Shasta and Redding areas. According to Jeri Wilcox, a field research data analyst at the Scripps Institution of Oceanography, the location is vital because storms in the region frequently split, with some moving north while others travel inland.

During atmospheric river events scheduled from November through March, weather balloons will be launched from the campus every two to three hours. Each device measures about four feet wide at launch and expands to the size of a school bus as it ascends to approximately 82,000 feet before descending by parachute.

The balloons are equipped with radiosondes that collect critical atmospheric data, including air temperature, relative humidity, wind speed, wind direction, and exact location. Meteorologists utilize this information to evaluate atmospheric moisture levels and estimate potential precipitation amounts, ultimately refining everyday weather forecasts for the public.
