Feb. 26 to March 3 should be the most volatile time frame, with the best chance of more snow and temperatures at least 15-20 degrees below normal. Daytime highs in the mid 20s and overnight lows in the coldest of locations near zero. This would be for a 2-3 day time period.
Exactly how cold it will get and whether we will see another major snow storm is still questionable, but bares some watching. You know I will keep you updated.
In the meantime, you have a GREAT WEEKEND to look forward to as Saturday should see temperatures in the low 50s with sunshine.
