A cold storm system ushers in unsettled weather to the Bay Area. Rain, hail and snow were all witnessed this day for California. Too bad I didn’t witness hail though… (Thursday afternoon, February 22, 2018)
**Weather update: Rain at last!
A change in the weather pattern was expected to bring rain & snow to California at last. Temps have been well below average in many areas in California. The high pressure ridge that has been controlling the atmospheric dynamic over the west had weakened and shifted away, causing a low pressure area to take over. Spotty rain showers & hail were observed around the Bay Area this day. Even Petaluma & Vallejo got pelted with hail mixed with rain this afternoon. Due to the cold nature of this system, some dusting of snow was observed over Mt. Hamilton & Mt. Umunhum. Overnight lows were to hover once again near freezing for many areas as the system slowly departs & skies clear. More scattered showers were expected by next week as another fairly dry system moves into the Bay Area. This next system was likely to deliver less than one-quarter inch of rain, which won’t do much to break the dry spell. But the outlook into early March offers a chance of more significant rains that would be welcome. As for the upcoming weekend, things should be mostly sunny & dry. Temps were to be a few degrees cooler Monday & Tuesday, along with the precip.
How about the drought status? About 45% of the state was in some level of drought as of February 6, 2018 according to the U.S. Drought Monitor. The numerical models were indicating that the storm door was to open up heading into March & was to finally allow low-pressure systems to bring more much-needed rain, hopefully. BUT, since this was still a week out, these long-range models are subject to change. Fingers crossed for a ‘Miracle March’…
