Today's rain in Cut Off was the most I've seen since moving here 11 years ago. What's in store for our area in the coming days? Will later tonight and tomorrow be anything like today? The radar doesn't currently show anything but the future loop shows more developing. It is through the Weather Channel app so I don't know how much to believe it.

Tonight through Thursday the rains should be more "scattered" so to say, compared to the last few days, if you do get caught under one of those scattered storms it can put down a lot of water in a short period of time though. However, the weekend looks concerning as deep tropical moisture looks to get pulled up from the lower Gulf of Mexico, through Louisiana. This accompanied with all the rain we have already received can create some flooding issues. Stay tuned for the latest.

Kind of spread out...QPF shows 2 to 3 inches over the next 5 days.

Mesoscale Discussion 0925
NWS Storm Prediction Center Norman OK
1100 AM CDT Wed May 31 2017

Areas affected...Extreme southeast Louisiana to Gulf coastal
counties of southeast MS and southwest AL

Concerning...Severe potential...Watch unlikely

Valid 311600Z - 311830Z

Probability of Watch Issuance...5 percent

SUMMARY...A locally greater, though marginal coverage, tornado risk
is possible today across extreme southeast Louisiana into the Gulf
coastal counties in southeast MS and southwest AL. WW issuance is
unlikely due to spatiotemporal limitations in this region, and given
that a somewhat greater potential appears for stronger rotational
couplets to remain offshore as waterspouts.

DISCUSSION...Trends in mosaic reflectivity and velocity data across
extreme southeast LA (primarily including St. Bernard Parish)
indicated a few thunderstorms with periodic, and occasionally
persistent, low-level rotational couplets moving to the
north-northeast toward the islands off of the southeast MS coast
(including Cat Island). General weakening of these couplets
occurred as they tracked closer to the coast, while recent radar
imagery showed these storms have shifted more toward the east, with
additional storms developing near buoy 42040 and tracking toward the
north.

15Z RAP suggested some increase in surface-3 km CAPE today (to
around 100 J/kg) and surface vorticity to be persistent near a weak
west-east oriented boundary located near or just offshore the coast
of southeast MS and southwest AL. Storms developing and/or
interacting with this boundary could have enhanced potential for
low-level rotation, while background vertically veering low-midlevel
winds (per WSR-88D VWP data) also support rotating storms. A very
rich boundary layer (precipitable water around 1.6 inches per 12Z
LIX sounding and mean mixing ratios around 15 g/kg) and moderate
instability should prove favorable for additional storm development
through the afternoon.

The daily deluge here in Baton Rouge. About and inch and a quarter. The frogs and toads are singing. Gonna be a big awakening when this trough eventually pulls out, ridge sets in, and the sun finally takes a summer hold with typical June weather.
