Next Round of Canadian Air Unlikely to Hit Atlanta
Atlanta certainly felt more spring-like today, after the cold air that followed last weekend’s storm was finally replaced by warmer southwesterly breezes. However, cold air continues to come in from Canada, with a doozy likely to hit the Plains states later this week.
The map below shows the GFS forecast for 2 AM on Friday. A low pressure system centered over Cleveland, Ohio is spreading between 1/2 and 1 inch of precipitation over Ohio, Indiana, and Michigan, most likely as between 5 and 10 inches of snow. Meanwhile an extremely high pressure dome is located over Alberta, Canada. The 1056 MB of pressure (highlighted with the arrow) is the equivalent of 31.18 inches of mercury — something you don’t see very often, and indicative of very low temperatures. In the plains, temperatures will probably drop well below zero.
Fortunately for those of us in Georgia, we’re not going to see much of a temperature drop. Because the low is going to remain to our north, we’ll see a return to highs in the low 50s and lows around freezing this weekend, followed by seasonable temperatures for the week of President’s Day. The long range forecasts call for normal temperatures and normal to above normal rainfall through the end of the month.
