The previous driest was 420 mm in the drought year. The weekend will remain cool, with milder weather well into Sunday.Īnd, come next week, the fall feeling is likely to last. The rainfall total for 2019 of 306.6 mm was 475 mm lower than the annual average and is the driest on record. She said the coolest temperatures will be felt on Friday.Īnd, a little more rain is expected toward the end of the week.Īccording to NBC 7’s First Alert Forecast, there’s a chance another weak weather system will move through San Diego County, bringing the possibility of light rain Thursday night and Friday. “This will increase clouds and keep temperatures much cooler, feeling more like fall with a chill in the air,” Parveen said. The onshore flow will persist through the end of this week and into the weekend. “Get ready to see and feel some changes.” “This will begin our cooling trend through the rest of the week,” Parveen explained. High temperatures will also be slightly cooler today.”Īn onshore flow will keep that pattern going for a while, too. “After yesterday's heavy rain and thunderstorms, this morning we're dry and will remain dry for the remainder of the day. “What a difference a day makes!” Parveen said Tuesday morning. Parveen and NBC 7 meteorologist Brian James both said that starting Tuesday, San Diego County will see much cooler temps. What's Next? Cooler, Comfortable Fall Temps Will Last Through the Weekend There were 2,074 in-cloud and cloud-to-ground lightning strikes detected over Orange, San Diego and Riverside counties.Ĭheck out the map below to see where the lightning occurred! #cawx /9udOf2OGDW- NWS San Diego October 5, 2021 It was quite a light show out there this evening! ⚡️ “Out of the past 21 years, 15 of those had measured rain for October, and some had several inches,” she added. So, it’s not uncommon for the region to get rainfall like this during this time of the year. “ĭespite October being known as a month for fire-prone weather in San Diego County, Parveen said that since 2000, there have only been six October months with no measurable rainfall in San Diego County. “More instability means more thunderstorms. “Areas of low pressure have more instability,” she explained. Parveen said the reason there were so many widespread storms Monday was because an area of low pressure was moving across the region. San Diego International Airport: 0.64 inches.
2019 RAIN TOTALS FULL
So, how did the rainfall stats break down across the county?

In the near future, we will also publish a report documenting differences between the Drd964x and nClimDiv datasets in the context of NJ’s climate history. Moving forward, the ONJSC will utilize and post climate data from the nClimDiv dataset. Improvements include the incorporation of additional station data and contemporary bias adjustments, as well as the implementation of climatologically-aided gridded interpolation to address variations in topography and network density that generates data values at a 5 km resolution. The nClimDiv approach provides an improved and more reliable gauge of divisional and statewide climate values. Statewide values were then obtained by weighting the divisions by their size. The Drd964x dataset approach computed climate division values from 1931 forward by averaging monthly data for all National Weather Service Cooperative Observer Network (COOP) stations in each division (NJ has three) to obtain monthly divisional mean temperature and precipitation (a different method was employed for the 1895-1930 period). This dataset replaces the traditional Drd964x values that NCEI and the ONJSC have used for many years. The National Centers for Environmental Information (NCEI) has launched a new divisional climate dataset called nClimDiv.
