Hard Freeze North Shore, Freezing South Shore...

Full precautions are needed again tonight across the North Shore as some spots might even dip into the upper teens.  Even the South Shore should dip below freezing and you may want to drip the water before you go to sleep.  These are the projected lows according to NWS.

There is only one thing that MIGHT save the South Shore from a freeze and that is the winds off Lake P.  

Satellite views have no clouds around and if the winds go calm, lows will easily get below freezing everywhere.  After tonight, a slow warming will begin ahead of another upper disturbance.

The top graphic is the dew points which are very low.  The center of the surface high should drift across North Louisiana tonight, but the question is...will it be close enough to die off the winds?

Return moisture off the Gulf is ahead of the upper low near Las Vegas.  As that disturbance heads eastward, look for a cold rain shield to develop across Texas and spread over us late Monday night.  As that system passes, I don't see any real surge of Arctic air behind it, but temps will still stay below normal/average.

Despite what the network newscasts try to show every night, this is a basic January weather map.  There are no "extremes".  For us, we should remain below normal/average (typical high 62) all week with several opportunities to see some rainfall.   

Finally, the "official" low at MSY will go down in the books as 33.    That temp. sensor has always read higher than surrounding readings ever since the new airport, with the added concrete, was developed.  My sensor was below freezing (30.9) and I'm in the heart of Metairie.   AGW alarmists will say it's global warming, but those of us who live here know different.  MSY may never again break any low temperature records.  Stay tuned!
