Return to the 80s expected before weekend cooling

An upper level pattern over eastern North America will be fueling the area with warmer temperatures, more clouds, and occasional showers for the mid-week period. Highs in the 80s and higher humidity may make it feel a bit more summer-like than the last few days, but no major heat is expected. Even the showers are not expected to be heavy, widespread, or persistent- more of the nuisance variety. Cooler weather arrives just in time for the weekend.

Today (Tuesday): The clouds that arrived late yesterday and overnight are here to stay for the next few days thanks to a very slow-moving pattern. So the weather today will be similar to tomorrow which will also be similar to Thursday. Temperatures should inch warmer each day. Look for clouds, some showers (30% chance), and highs in the upper 70s mainly today. Confidence: Medium

Tonight: Mostly cloudy with more showers (30% chance). Humidity levels will be higher (assistance for you allergy sufferers!). Lows will be in the upper 60s. Confidence: Medium

Keep reading for the forecast through the weekend...

Tomorrow (Wednesday): Clouds will be the main theme, but we should see slightly more shower activity (mainly light and sporadic again) with a 40% chance. And temperatures will make their way higher most likely. Look for low-to-middle 80s with light winds from the south.Confidence: Low-Medium

Tomorrow Night: Clouds continue with scattered showers (30% chance) and warmer lows again in the upper 60s. Confidence: Low-Medium


Thursday brings yet another chance (40%) of pesky showers and even some thunderstorms. Highs should be in the middle 80s again with light winds coming from the south. Confidence: Low-Medium

Friday is expected to find a cool and dry high pressure center in eastern Canada moving down to break up this week's cloud and shower party. The impact should be gradual, so we are looking for partly cloudy skies with highs in the upper 70s to low 80s. We could see a stray morning shower. Confidence: Low-Medium

The weekend looks fantastic- if you only count Saturday. Sunny skies, pleasant breezes from the north, and highs in the lower to middle 70s should dominate our Saturday. Clouds increase again Saturday night and showers return in advance of another cold front. Some thunderstorms are possible with rain showers on Sunday and highs in the mid-to-upper 70s. Timing and details are subject to change for the weekend since we are still a number of days away yet. Stay tuned for updates. Confidence: Low-Medium

The early look at next week suggests we could see a cooler pattern with occasional clouds and shower opportunities. Bring on the autumn!

Hopefully we won't get the kind of mess Atlanta is getting. The rain should be more scattered and come in two or three waves between now and Sunday. Next week could be quite dry with more fall-like temperatures.
