For the past several months, a product that has received consistent use at the ABQ office has been the Blended TWP and percent of normal product. We are in the middle on a somewhat lackluster monsoon season, and a typical monsoon pattern has been rare this summer. The Blended TPW product is an excellent tool for depicting areas of deep moisture, moisture starved areas, and the gradient between them. On August 13, 2009, we were gearing up for some potential heavy rain. We had been tracking the deep moisture to our south for a couple of days. On the August 14th image (not shown), increased moisture over both Arizona and New Mexico was evident, but a lack of Mexican data negatively affected the image.
Below are examples of a 4-panel used by several of our forecasters, with the Blended TPW, percent of normal loaded with a water vapor image and the GOES Sounder PW. Images are for two recent consectutive mornings, 11 Aug and 12 Aug, around 12Z. Note the evidence of high PWs south of Arizona in the first image, but a lack of information in the second image due to missing data from Mexico. Our understanding is that the missing Mexican data is due to problems with the U of A SUAMI net.
