Forecasting Contest - Atlanta Forecast for Tuesday

Good morning! I am going to do my best to keep up with providing detailed-as-possible weather forecasts for the forecasting contest in my Weather Analysis I class. This week, we start off with Atlanta, Ga...

Currently, high pressure is dominating the southeastern states with the high sitting to the northwest of the ATL area based on HPC surface analysis. Models are expected to move the high to the east today and tonight, which will help usher in a more easterly flow into north Georgia starting no later than tomorrow morning. This will keep temperatures a little more moderated, but keep skies mostly clear and very nice for the area.

A light easterly wind, very little cloudcover and dewpoints in the 40s and 50s will allow good radiational cooling tonight. NWS-Peachtree City is calling for a low near 58 tonight, but I think that's too cool, mostly because of the more easterly flow. I think the low will be a little near MOS guidance and I'll call for a low of 61 tonight with mostly clear skies.

Tuesday will be very nice with the high to the north and maybe slightly east of Atlanta metro. The light easterly flow will continue. I'm calling for a high of 88. No rain is expected for Tuesday.

In a nutshell, expect some nice weather in the A-T-L, so get out an enjoy it!
