The Quiet Before The Storm...

The next two days will be beautiful with crispy cool nights and sunny mild afternoons.   But the thinking hasn't changed from yesterday and models are agreeing on a major Winter storm devloping over the Southeast this week.   Here's why...

I've drawn the main upper flow on the satellite views with storms lined up off the West Coast our into the Pacific. The southern jet stream remains fairly inactive, which is typical of a La Nina year.  The bottom picture has a modest upper trough over the Great Lakes.  But look what the models are forecasting.

They take that modest trough and sharpen it in the middle graphic valid for Sunday Morning, cut off over Norther AL/GA/TN.   That should trigger a surface low down over Georgia with snow & cold air pouring around the backside.   NWS has mentioned that some flurries could make it as far south across parts the the North Shore, but no accumulation is expected.   Our real concern will be how cold will it get here on Monday morning?  Righ now I'm thinking 25-30 on the North Shore with 30-35 south.  We still have time to watch and fine tune that forecast, but it still looks like Saturday (in the warm air) will be the day to prepare your yard for the coming cold.

Across the nation, not much is happening yet, but that will change as we head into this weekend.  Our dew points are quiet low (dry air), but with clear skies and light winds, some frost could form especially away from Lake P.

After a mostly cloudy Wednesday, Thursday & Friday will see abundant sunshine.  Note the coming cold blast will not hang around very long.  A warm up begins on Tuesday into Wednesday ahead of another cold blast coming for late next week.  January is often an exciting time of the year weather-wise for south LA/MS and this weekend will live up to that past history.   Stay Tuned!
