RGV Weekend Forecast (3/9/2012)

Spring Break is just around the corner for many students.  For many students, their destination will be South Padre Island. I will be making a forecast for the week of 3/12 to 3/16 in the next couple of days.

Currently, cold front pushed through the Valley early this (Friday) morning, sparking up showers and thunderstorms.  Temperatures ranged from the upper 40s to lower 50s across the valley, today.  Along with the cooler temperatures, light rain has been falling for most of the day.  Aloft, a 500mb closed low over New Mexico will retrograde westward tonight before moving east and north tomorrow and Sunday.  This will create showers and thunderstorms for much of Texas, Oklahoma, Louisiana and Arkansas over the next couple of days.  For the Valley, the cold front that pushed through this morning will stall offshore and move northwestward as a quasi-stationary/warm front tonight and into Saturday.  This might spark a few more showers and possibly a few thunderstorms tonight and tomorrow.  Regardless whether the rain continues for tomorrow or not, cloudy and overcast conditions can be expected over south TX on Saturday, due to the southwest flow aloft.  Temperatures will remain cool, but warmer, for tomorrow.  High temperatures will reach the lower 60s for much of the Valley.  Temperatures will be even warmer on Sunday, with temperatures reaching the upper 70s.  The reason for this will be the shifting of the surface winds out of the S and SE.  

In summary, tonight will chilly with showers and a possible thunderstorm.  Low temperatures will be in the upper 40s.  Saturday will be another cloudy and cool day with showers and possibly thunderstorms around.  Saturday temperatures will reach the lower to middle 60s.  Sunday will be warmer, with clouds and rain possible.  Afternoon highs will be in the middle to upper 70s.
