Aiexpress – In northern California today, there is a chance of severe thunderstorms and a few tornadoes. There is also a chance of severe turbulence over Californian skies, with the biggest risk being east of the San Francisco Bay area. Today’s bad weather is caused by another run of atmospheric river events.
Rainstorms, heavy snow in the mountains, high winds, and heavy rain along the coast and at low elevations are all things that California will experience because of the atmospheric river event. A tornado or two could happen in the Sacramento Valley area because of scattered thunderstorms. Today, there is a high chance of tornadoes in this area, according to the National Weather Service’s Storm Prediction Center. Not everyone will see a tornado, but the chances of at least one or two happening are statistically important.
Today, the core of a strong, large-scale low-pressure system will keep moving inland. California is still getting a lot of rain because of this weather trend. There is a small chance that flash floods will happen in the northern part of California on Tuesday because of more heavy rain. There is also a modest risk of flash flooding along parts of the southern California coast, where heavy rain will fall in concentrated areas due to the terrain. This risk will last through tonight. On the other hand, higher regions can expect a lot of snow.
The low-pressure storm should get weaker by Tuesday. This will let the rain or snow get less widespread and less intense over time. Even so, more leftover energy from the Pacific will cause more rounds of light to moderate rain or snow that depend on elevation through Wednesday. At the same time, moisture from the weakening low-pressure system will keep moving deep into the Intermountain West. This will bring more rain and snow to the Great Basin and the northern Rockies over the next few days, and by Wednesday, it will have reached the central Rockies and the Four Corners.
The Aviation Weather Center of the National Weather Service is also warning of bad weather in the air today, in addition to bad weather on the ground. Signals called SIGMETs are sent out to warn flight teams of dangerous conditions in the air that could cause a lot of turbulence.
The Flight Weather Center (AWC) of the National Weather Service watches over flight weather in U.S. airspace and sends out alerts when there is bad weather or bad flying conditions. The AWC issues severe weather warnings known as SIGMETs, which stands for “Significant Meteorological Information.” It includes weather-related information that affects the safety of all aircraft flying through a certain zone. AIRMETs are sometimes sent out as well. These are less serious warnings about turbulence, visibility, and icing than SIGMETs.
