Interesting Forecast for the Weekend

Well the second “Polar Vortex” has made its way in to the eastern part of the US and as you can tell it is NOWHERE near as cold as the one that came through the first week of January. Yes, we are well below normal with temps across the area in the lower 40’s and upper 30’s, but you can feel the strength of the sun this time of year. Tonight it is going to get very cold across the area with the hi-res NAM showing overnight temps in the mid to lower 20’s, records are in the lower teens.temps 7am

Tomorrow and Friday are what I call transition days where there is really not a whole lot going on in terms of weird weather. We will tomorrow’s highs make their way back to the upper 40’s in the metro area with mid to lower 40’s in the mountains and northern counties. I think the NAM is under doing our temps a little cooler than what it is showing here. I think we make to right at 50 here in Atlanta.4pm

Friday will yet again be a bit warmer with temps making it back into the mid 50’s in the metro area and temps in the upper 40’s in the northern counties and the mountains. Friday night is when things start to get a bit tricky. A disturbance comes in late Friday night through Saturday morning and will give a nice dousing of rain through early Saturday morning. Check out the disturbance on Friday night at 500mb, then 500mb for early  Saturday morning, and the subsequent rain after that.Fri pm 500 Sat 4am 500 Sat 1am rainAfter that the models want to clear us out and warm us up, but I don’t think that is happening. Most of the models are hinting at a mini wedge for Saturday, all models are warming us up into the 60’s.. I think for a majority of the day on Saturday we are going to be gray and cool with highs only in the upper 40’s and lower 50’s…sat pm

Some of the area to the SW of the city will see 60’s, but not here in Atlanta… The good news is that on Sunday temps at 5,000 feet will warm up big. That means that for us here Sun 850in the N Georgia area we will be back into the lower 60’s and somewhat spring like weather for the second half of the weekend.

I will address the potential for another shot of colder air in the evening edition when the new long range model data is ready.
