The change in the prevailing jet stream weather pattern I mentioned here Monday morning still looks to be on track as seen in forecast model maps above.
The jet stream flow flips from coming out of the Southwest to coming down from the Northwest.
Forecasting highs today of 68-71 not far from a record. The normal or average high this time of year in Atlanta is just 52! If we get enough sun we could tie or break the record.
A HARD FREEZE is due several mornings in a row starting Monday with lows in the 20s, a few readings in the teens not out of the question by Tuesday or Wednesday.
The downward temperature trend will occur in steps with the first step down Thursday, another Friday and the big one starting Sunday and on through next week.
These will be the lowest readings since mid-November as a taste of winter returns.
We also dry out along the way, especially after Saturday.
Just a few showers or an isolated thundershower today, mostly dry tomorrow and Friday. Then showers and maybe a thundershower Saturday. Then dry Sunday-Thursday.
ESTIMATED AVERAGE RAINFALL TODAY THROUGH SATURDAY NIGHT:

As is always the case my specific forecast will vary from others and from models.
