Temperatures will soar well into the triple digits in the San Diego County deserts Tuesday and the blazing conditions are not expected to let up until this weekend, according to the National Weather Service.
Temperatures will reach well into the triple digits again Thursday in the San Diego County deserts, according to the National Weather Service. Conditions in the rest of the county will also remain warm, but will be slightly cooler than Wednesday.
The hottest temperatures of the week are expected Wednesday throughout San Diego County, but relief will arrive this weekend, according to the National Weather Service.
High pressure over Baja California will keep temperatures warm through Friday throughout the county, then temperatures will drop quickly and return to around seasonal average on Sunday, forecasters said.
A heat advisory is in effect until 9 p.m. Friday in the western valleys and an excessive heat watch will also last until 9 p.m. Friday in the deserts.
High temperatures Wednesday are forecast to reach 82 degrees near the coast, 90 inland, 96 in the western valleys, 95 in the mountains and 110 in the deserts.
A ridge of high pressure off the coast will spread over California, bringing the first heat wave of 2020, the National Weather Service said. High temperatures of 85 to 95 will be common, with the hottest readings on Friday and Saturday.
Temperatures will remain mild Tuesday in San Diego County, but the mercury is expected to rise quickly starting on Wednesday, according to the National Weather Service.
In San Diego County and across California, it’s been an awesome April for precipitation.
The Sierra snow pack, although still much smaller than normal for this point in spring, has partially made up what had been a huge shortfall just a few weeks ago. And just about every place from the desert to the coast has benefited from a substantial soaking.
Last week’s record-breaking storm lifted San Diego County well above normal precipitation for the rainfall season. The city of San Diego has had its wettest spring in decades, and it has already recorded 3 more inches of rain since Oct. 1 than it normally gets in an entire year.
Heavy rain will fall at times in San Diego County Thursday evening and snow is likely in the mountains, according to the National Weather Service.
As of 1 p.m. Wednesday, 5 inches of snow had fallen on Palomar Mountain. Palomar Mountain is expected to get up to 3 more inches of snow by late Friday morning, while Mount Laguna could get between 6-7 inches and Julian could get trace amounts of snow, meteorologist Miguel Miller said. Snow levels will be around 4,900 feet Thursday morning, then rise to 5,500 feet by this afternoon and remain there through Friday morning.
A flash flood watch is in effect throughout the county until Friday afternoon.
Much-needed snow will blanket California’s Sierra Nevada high country this weekend into next week, bringing hope of a “Miracle March” that could replenish vital, water-providing snowpack after a record-dry February.
A major change in the weather pattern is ahead for Northern California as unsettled and colder conditions will emerge. This change will be accompanied by low pressure that will track southward near the West Coast this weekend and will remain near California early next week before this system pushes eastward into the Great Basin.
The most recent U.S. Drought Monitor data, released Thursday, show that about 48% of California is in moderate drought. That’s up from 34% a week ago.
An additional 30% of the state is abnormally dry, according to the data.
The data were compiled Tuesday, so the figures do not reflect moisture from Southern California’s most recent storm.
More rain showers are expected Thursday throughout San Diego County and there is a chance of thunderstorms Thursday afternoon in the mountains and deserts.
The National Weather Service issued a flash flood watch from noon Thursday through Thursday evening in the mountains and deserts.
The low-pressure system making its way inland is expected to produce heavy rainfall at times, which could cause flooding in low-lying areas, areas with poor drainage and desert mountain slopes, forecasters said.
