Yo-Yo thermometer pattern continues

But change in pattern possible end of this month or early March

Our thermometer roller-coaster ride looks to continue the next 5-10 days with freeze thaw freeze.

Odds for any snow or ice with significant impact for Metro Atlanta looks slim this week, so far. It can change so listen for updates on 95.5 WSB Radio.

Tomorrow Tuesday morning there could be some patchy ice in parts of Metro Atlanta not from falling precipitation but from run-off as temperatures are expected to fall below freezing by sunrise. MOST roads should dry off before temps drop with the greatest threat Near and North of a Rome to Gainesville line.

It does look like the extreme pattern of the jet stream will relax by the end of this month into early March as high-latitude blocking pattern finally breaks down some and begins to shift and become less cold and less stormy:

True arctic air low pressure retreats NW while Sargasso Sea-Bermuda high pressure ridge expands over the SE.

However there are some signals that the previous (current) pattern will re-load to some extent with a recharge of polar air and storminess before the Spring Equinox March 20th. By the end of March it’s hello La Nina Spring for most of the country.

Meanwhile we will have to keep an eye out for any severe weather episodes in the warm-sector of low pressure systems as they come and go.

Until the start of Spring, enjoy the yo-yo ma. ;)
