While only a few degrees difference, the lower latitude often precludes some low pressure systems from the Midwest from reaching as far south as especially the coastal areas. There is a marked difference in relative humidity % between Houston and Beaumont/South Louisiana in general. Rule of thumb is you can usually take our humidity here and add about 10% on any given day to get the RH in Beaumont/Golden Triangle/South Louisiana
I was born and raised - and spent 33yrs of my life - in South Louisiana. It is much more humid there in general.

The slope/angle of the coast also plays a big part,as the more east you go in SE Texas at the same latitude the closer you get to the Gulf.While Beaumont's latitude is farther north than Houston,its also closer to the gulf due to the angle of the Texas coast.I use to live in Louisiana also and Mississippi.Louisiana is the wettest part of the country outside of high mountain ranges.

It's that angle from the Gulf since most of the prevailing mid and upper level air is SW to NE or West to East.

For example, Corpus Christi is right on the Gulf Coast but only receives about 32 inches of rain a year. They are closer to the SW cap and Mexican air squashing rain chances. The dry line never makes it to Corpus inhibiting rain chances in April. September and later tropical season are their best chance of rain. Brownsville sees less than 27 in of rain/year.

...whereas LA, MS, AL, FL panhandle coasts are deluged with Gulf moisture all year round! 60+ inches/year are typical.

Indeed there is a steep gradient for rainfall on the west side of Houston which continues west and toward Mexico...

I was just thinking how this spring is giving me a lot of 2016 vibes. I actually think that people who are missing out now might be glad they did later on this month. In 2016, the rain really picked up towards the end of May and we are only at the beginning right now.

Spring of 2016 was wet. Same with Spring 2015. I would not be surprised if this ends up being the wettest May on record.

Yep, I agree.

The next system to watch is on Sunday.As a pretty potent disturbance moves in.

Seeing how the models have significantly underdone totals, and we have over 24-36 hours to recharge the atmosphere, I wouldn’t be surprised if those totals verify or we exceed them.
