Rainy time model sets in the region

A February meteorological scheme marked by high pressure, a sun and especially pleasant days gave in in March to the one that led to a drop in pressure and the arrival of cold and often rainy weather.

Do not expect this change of soon, said the National Weather Service.

“The hemispherical scheme is active and the (system) locks on a water vapor,” said NWS meteorologist Rick Canepa on Tuesday. “It therefore seems favorable for the development (of storm) in at least in the middle of the month. It is not unusual. Mars is normally our most essential fourth month. »»

The next stage in the development of the storm should bring a decent amount of rain on the southern bay and the central coast later Tuesday. Canepa said the rain could last until Wednesday morning before another “reinforcement behind it” should bring additional rain on Wednesday evening to Thursday.

The meteorological service said that the most intense rains of the two systems should be along the peninsula and in the Bay of South, the central coast and the mountains of Santa Cruz. These areas should all receive between half a pump to a full thumb of rain from the two systems.

Precipitation should be considerably less in the part of East Bay and North Bay in the region. Livermore should receive between two tenths and a half-pouce, while the areas of the Costa Costa, Alameda, Napa and Sonoma counts should only receive wet things.

“There will be a little more precipitation on a state scale with the second,” said Canepa.

The rain will fall in the middle of continuous cold temperatures. Temperatures should not be released from the 1950s before Friday, and nightcloths were expected to dive in the 1940s in most places. They will be in the 1930s in the Far East Bay regions.

It will change a little on weekends, according to Canpa. Basse temperatures at night will remain just as low, but high temperatures should go back to the mid -60s in the middle of the dry sky.

After the weekend, the weather service said that more rain would arrive. Canepa said that more progress in the weather model will help them determine how serious this precipitation will be.
