Normal Temperatures Likely To Return This Weekend
So far, May is running about 3 degrees cooler than normal, on average. The normal mean temperature through May 14th is 66.9 degrees, while we stand at 63.8 degrees — actually cooler than what we had in April. However, Atlanta temperatures are likely to get back towards normal by the end of the week.
The main cause of our cool and wet weather this month has been a persistent upper low pressure system over the Great Lakes that hasn’t moved a lot for the last week to ten days. While this has kept temperatures (and humidity) lower than expected in the South, it has caused misery in the northeast.
In Boston, for example they are three degrees cooler than normal as well (averaging 53 degrees), but they have had almost seven inches of rain through May 13th, 500% of normal. The storm has forced governors in Massachusetts and New Hampshire to declare their states disaster areas, with the storm bringing up to 15 inches of precipitation in some spots.
The whole soggy mess is expected to finally move away this week, and that will bring weather more typical of late May to the East coast. By this weekend, we could see highs in the low 80s, which is about normal for this time of year. At this point, I don’t expect to see temperatures much above normal until Memorial Day weekend.
And, it looks like we should be grateful for the rain we’ve gotten over the last two weeks. National Weather Service long range forecasts are calling for less than normal rainfall once the upper low, and the fronts it has been driving into Georgia finally departs.
