As a meteorologist, I search the maps every day for what I call "triggers."  Triggers are certain atmospheric features that could cause the rapid rising of air and thus produce showers and t-showers.

Sitting over northern Mexico Thursday is just such a "trigger."  A large low pressure system is spinning counter-clockwise and will produce bands of energy.  Since the RGV rarely has a lack of available moisture, we have the perfect combination for a day of showers and t-showers and the potential for some locally heavy rainfall.

This is good news because we are WAY BEHIND on our normal year-to-date rainfall amounts. 

Here are the rain amounts as of midnight with the amount of rainfall that is normal this time of year:

Brownsville:  7.00 inches received, 11.04 in. normal

McAllen:  3.50 inches received, 10.04 in. normal

Harlingen:  5.17 inches received, 11.08 in. normal

So let's hope our chance of rain materializes!  For my long range forecast, click here.. http://www.kveo.com/weather
