Barry Struggling But getting Stronger...

Over night the changes with Barry have been subtle.   Forward motion has increased (good) a little (WNW at 5) and northerly shear has kept the broad rotation lopsided (asymmetric) with all of the T-Storms south of the center.  However, since he is now within land-based radar, it's apparent the eastern side is becoming wetter as expected as radar echoes are increasing.  This storm will still bring us heavy rains, but the question remains, who gets the 15-25" models are predicting?   NHC in their discussion said the new forecast track is not different from last night.  Pretty much, however, if you follow their centerline track like I do, it has been nudged about 30 miles to the west Now Lafayette not Morgan City, more in line with the Euro track solution.   That's why I think the heaviest rainfall (15-20") will be more over Morgan City northward to Baton Rouge.   We need to watch that a rain band rotating around Barry doesn't set up over us. (training).   Models saying 10-15" for NOLA.  I think 3-5" more realistic with a few locations up to 8".  If it's spread out over many hours, pumps should be able to keep up.  You can get out and around today without issues.  Tonight and Saturday plan to spend your day "hunkered down".  Latest NHC info has a pressure drop, which tells me Barry is getting stronger.  Winds are already gusting 40-50 mph along coast and 30-40 at Lakefront Airport.   The main threat will be heavy rainfall, but I noticed the water in Lake P. is very high and as Barry turns to the north tonight & Saturday, winds(now ENE) over the Lake will become strong from the south forcing higher water over the seawall on the North Shore.  Something to watch for tomorrow.  Next update from NHC at 10 AM.  Don't expect any major changes in track prediction.  Stay tuned!
