It there an end in sight? It looked that way a week ago….just a head fake!
Coldest May? Actually for Fresno, both May of 2010 and 2011 were tied at -3.7F degree below normal for the month.
It appears that another in the series of cool upper level low pressure systems will track across the Sierra today and tonight bringing snow showers and gusty winds to our region. Lake wind advisories go into effect at 1:00pm this afternoon and continue through 8:00pm tonight. The strongest winds will occur late afternoon and into the early evening hours with the FROPA. Then an even wetter system arrives for the weekend and may end up bringing a good 4 to 8 inches of snow above 9000 feet Sunday into Monday. Snow showers could begin anytime beginning Friday night. So here we go with another unsettled weekend and the way the WX maps look for next week it may continue for some time. Why?
An expansive warm core ridge is expected to remain anchored from the mid southern states southwest to Northern Mexico. This working teleconnection tied with a persistent positive upper height anomaly off the British Columbian coast will keep a signifacant negative height anomaly in the mean off the Northern Coast for the next week, possibly two. This leads to a series of deep cyclones dropping down into California for the next week to 10 days. The guidance, operational and ensembles are all in agreement concerning the next system to effect California this weekend. After the weekend the ECMWF keeps a trof in the mean over California pretty much all of next week with a series of small features dropping south over our state as either coastal sliders or interior sliders. The next more organized system is poised to drop south in California about Saturday the 12th/Sunday the 13th. “It ain’t over till its over!” (Yogi Berra)
