.DISCUSSION...A heat advisory has been issued with dew points not
falling and temperatures continue to rise. High dew point air
continues to advect into the region under a moderately strong
southerly flow off the warm Gulf. Subsidence and heat compression
for the approach of a cold front should allow for ambient
temperatures to rise a few more degrees allowing for heat indices
to exceed 110 degrees this afternoon for all areas of the Rio
Grande Valley.
