Another light freeze after the storms

  • 6:20 am Tuesday, March 20th, 2018 by Kirk Mellish

The low pressure and frontal system that brought the stormy weather Monday night with scattered damage and power failures will turn into the 4th Nor’ Easter snowstorm and bring another bought of below-normal temperatures to Atlanta.

Some sleet and snow showers or flurries are even possible Wednesday in the high elevations of the Northeast Georgia mountains.

Severe weather risk Monday night

  • 5:59 pm Monday, March 19th, 2018 by Kirk Mellish

It won’t rain non-stop tonight and not everyone will get a severe storm.

However, the threat of some damaging thunderstorms is still very real, level 3 on a scale of 1-5 and level 4 NW, this includes the risk of a tornado:



Particularly dangerous situation in AL where odds of a strong tornado are 80%

Severe weather risk Monday

  • 11:44 am Sunday, March 18th, 2018 by Kirk Mellish

A strong and complex low pressure system and associated warm and cold fronts will be moving across the Southeast states Monday into Tuesday. Rain is likely at times, there will be lulls in the rain for dry hours.

Scattered thunderstorms are also expected late afternoon, with a squall line possible overnight. Colder weather will follow by mid week with a light freeze in some areas.

A risk of damaging winds, hail, dangerous lightning and possibly a tornado is ESTIMATED to be 4pm to midnight, give or take a couple hours.

See-saw temperature pattern continues

  • 12:13 pm Thursday, March 15th, 2018 by Kirk Mellish

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.

The systems impacting us ride Northeast up the Atlantic coast and may turn into [More]

Water restrictions lift as drought ends

  • 11:21 am Friday, March 9th, 2018 by Kirk Mellish

Drought has ended for now in most of the metro Atlanta area, while persisting slightly in NW Georgia and spreading and worsening in central and South Georgia.

Across the state 2.1 million in population is covered by some drought classification.

More rain is on the way the next 3 days:

My local 5-day forecast here.

Repeating weather pattern

  • 8:44 am Tuesday, March 6th, 2018 by Kirk Mellish

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.

See the sequence:


The temperature brush back for the rapidly advanced plants is not good. We’ll have to keep an eye [More]

2-day freeze possible

  • 8:36 am Monday, March 5th, 2018 by Kirk Mellish

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.

Light frost weekend, hard freeze possible next

  • 7:01 am Friday, March 2nd, 2018 by Kirk Mellish

As forecast for weeks now a chill returns to the air the next couple nights, with light frost possible the next couple mornings, mainly in the usual colder low spots in the Northern suburbs.

Long time followers on Twitter and regular readers of this blog know I’ve been warning of the potential for another significant cold snap in early March for a couple months now, thanks to non-computer model methods.

Well now the computer models are seeing it as well.



Rain returns, cool off follows

  • 2:02 pm Tuesday, February 27th, 2018 by Kirk Mellish

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]

Weather change still looms

  • 8:08 am Thursday, February 22nd, 2018 by Kirk Mellish

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]
