In the good ole springtime. The thermometer see-saw pattern will continue through the end of March, and probably half if not all of April.
After yet another light freeze Thursday morning, a big warm up the next 5 days including 70 or above.
Yes rain and a few thunderstorms are likely this weekend into Monday, but plenty of dry hours and dry areas to go around, far from a washout as it looks now anyway.
We need to monitor a severe weather risk for Monday based on CIPS analog guidance.

One low pressure system and cold front today in our area with another cold front passage tomorrow. They turn up the Atlantic coast and become the 2nd big Nor’easter storm which helps bring freezing temperatures back to Georgia in the days ahead.
The 3rd in a series of low pressure systems and cold fronts brings more rain late Saturday and Sunday, which turns into yet another Nor’easter snowstorm for the Northeast and again tries to pull down some more cold air here.

The long term forecast discussed here for over a month now still on track. We had the expected light frost over the weekend and after the return of mild weather, the next cold snap is already on the horizon Wed./Thur. as we see the upper-air pattern flip again as seen in the WxBell graphics:
The European ensemble is showing a couple meager attempts at snow around Blairsville, while better odds are in the mountains of North Carolina.
Back and forth up and down temperature pattern expected to finish the month and start April.

A couple days of showers after the nice break Monday afternoon and Tuesday, sunshine often lifts spirits, especially given the frequent long spells of gloominess we’ve had.
It does not look like non-stop rain, but periods of rain are likely Wednesday and Thursday, details on the radio and in the online forecast section.
Highest flooding risk again to our North and West. No severe weather is expected as of now, but it bears watching just in case.
Dry weather expected on the weekend, with a noticeable chill in the mornings, some LIGHT frost and freeze possible, particularly in the usual colder spots [More]

If you follow me on a regular basis then you’ve had weeks of advanced notice of a cooler pattern change for March.
In several previous blog posts I’ve shown the crazy links to past extreme weather that has occurred following similar weather patterns to those evolving this year. Most recently here.
It is not unusual to have warm surges in the East part of the country in February in a La Nina. Over half of NYC record highs in February for example have occurred in La Nina winters.
It turns a little cooler by next week but still warmer than normal for [More]
