More weather records are in jeopardy today in downtown Sacramento as a stubborn high-pressure system brings more mild, dry weather.
This week, each new day without rain pushes this winter season higher in the record books. After today, downtown Sacramento will have recorded 45 consecutive days without measurable rainfall, ranking as the second-longest stretch in history, beating the previous record set in 1976.
Wednesday will tie the all-time record of 46 days, set in 1884, according to the National Weather Service.
If Thursday ends without rainfall – and there is none in the forecast – this winter will record the longest dry stretch in downtown Sacramento’s weather history, which dates back to the 1870s.
Jim Mathews, a meteorologist at the National Weather Service in Sacramento, acknowledged there has been confusion about this record for a winter dry trend.
At first, the weather service indicated the record would be broken today. Then it looked more closely at the weather history data and found two prior winter periods in which a “trace” was recorded. As a result, these two periods – 1884 and 1929 – had been excluded form this particular record.
But a trace, Mathews explained, is not considered “measurable” rainfall. So in reality these two periods must be added to the list of prior record winter dry spells. Adding them means downtown Sacramento has to notch two more dry days before it can break the record. This makes Thursday the crucial day.
If Thursday ends without measurable precipitation, Mathews said, this will become the longest continuous winter period in downtown Sacramento without rain.
“Sorry for the confusion, but with 150-some-odd years of weather records, it’s hard to keep it all straight,” Mathews said. “We were even confused for a while.”
A heat record also could fall today. The high temperature for today is expected to reach 70 degrees, according to the National Weather Service. If so, that would tie the record for the date, set on Jan. 21, 1976.
