Worst Has Passed...For Now

Several waves of storms have rumbled across SE LA/MS this morning prompting a number of flood warnings to be issued.  Radar is showing the worst/heaviest of the rain now east of the city and we should see some drying this afternoon.

The triggers for today's rainfall are many weak upper disturbances rotating around several low levels swirls.  One weak swirl is moving inland along the Mexican coast with a flair up of storms over the southern Gulf.  The stronger, better defined upper low is in east Texas with clusters of storms rotating around it.  Until that low gets to our east, expect our rain chances to remain high/above normal into Friday.

What I'm unsure about is the effect the surge of Saharan dust will have on our rain chances.  Satellite pics show how clear the skies are to our east and over Florida while you see a murkiness over us. The dust cloud covers the Caribbean with a break moving across the eastern islands before more dust pours off of Africa.  That should keep the Tropics quiet for awhile.

What's left of Dolly is now just a weak low well east of Cape Cod.   4 named storms with no major impacts so far, which is typical of early season storms.  The heart (Aug-Sept) of the season is still 5 weeks away.  Stay tuned!
