The last 30-days of precipitation (rain and snow) across the Lower 48 is 100% of normal or right on the dot average for the past 30-years. However, it\u2019s not evenly distributed at all with much below normal precipitation across the Plains into the Midwest. The Southeast centered upon Atlanta is wet as well as the Mid-Atlantic. Not much snow to end winter, but plenty of rainfall.

We need to monitor the dryness across the Plains over the next several weeks as drought indicators may start increasing heading into April.

Short Term | Next 3-days

\"\"

The next storm system is forming across the central U.S. and will track through the Great Lakes into the Northeast by Sunday. The frontal system will have plenty of Gulf of Mexico and subtropical moisture leading to a flood threat in the Southeast.

On the backside of the low, there is enough cold air to drop snowfall especially away from the New England coast Sunday into Monday.

Over the next 3-days, the NWS rainfall shows another band of 2-4 inches across the Southeast including Atlanta, which does not need anymore rain.

Still marking Tuesday March 19, 2024 as a day to watch for a trough with Arctic air \u2014 albeit mid-March, almost Spring, cold air with the \u201cpolar vortex\u201d plunge into the Southeast. Need to watch for a frost/freeze into Atlanta in 12-days.

This final period shows the threat of colder air w/ensemble mean of -5 to -6\u00b0F compared to normal. However, this is a strong signal for cooler air, and the magnitude will increase as the ensembles sharpen.
