Here we go again, another 1" - 2" of rain on a 24 hour basis until Wednesday afternoon. The amount of rain is important because flooding becomes a real issue the first half of this week. A record set back in 1900 of over 14 inches is within reach, since over 12 inches of rain has fallen at both airports. The coastal communities will see the heaviest amounts of rain through Tuesday.
By Tuesday a tropical wave pounces on the Texas Gulf coast with a fresh surge of tropical moisture. Even better chances of showers on Tuesday and Wednesday as this moisture is forced Northerly through the day. If the bayous and rivers have a chance to fall during the evenings, then street flooding should be the main issue. If not, anyone living along these major arteries that provide most of our drainage could be compromised.
Relief finally comes this weekend as seen below with a major high pressure ridge anchored over the Midwestern plains for the weekend. Vast amounts of Saharan dust indicating a dry atmosphere has shut down the tropics for a few days, so maybe we'll get a chance to dry out.
