The table above covers the past ten days and shows the daily mean departure from normal of temperatures (+06d/n) at the stations listed. The mean temperature is determined by taking the high and low for the day, adding them together, and dividing by 2. The average departure from normal is determined by taking the mean for each of the six days, summing those up, then dividing the sum by 10.

     [& = Station elevation is above this pressure level / F = Failed / M = Missing, no report received / D = Delayed, no report yet / * Questionable data]   
This table displays precipitable water** (PWAT), and the temperatures at 925mb, 850mb, 700mb, and 500mb from upper air soundings made around 00 UTC and 12UTC (6pm CST and 6am CST).  The table shows 12 stations near Central Texas that make these observations. At times, I may add the current data for 6pm. In the table above, PWAT is in inches and all temperatures are in degrees Celsius. **Precipitable Water - measure of the depth of liquid water at the surface that would result after precipitating all of the water vapor in a vertical column over a given location, usually extending from the surface to 300 mb. 
[***Explanation of temperatures showing +0 or -0. The soundings are reported in 0.1 Celsius. I round them up or down to even numbers, except in the case of readings between +0.5 and -0.5 Celsius. Those I enter as +0 or -0. So, for example, a reported reading of -0.4 would be entered in the table as " -0 " and a reading of +0.4 would be entered in the table as +0 .]

MANDATORY LEVELS:
By international convention, these specific pressure levels must be reported in the RAOB message: the surface, 1000, 925, 850, 700, 500, 400, 300, 250, 200, 150, 100, 70, 50, and 10 mb.. The information for some of these levels is plotted routinely on constant pressure charts to show the spatial variability of these levels and it is used as input in the numerical weather prediction models.


The College of DuPage meteorology program produces a vast number of graphics based on hourly surface data, 12-hourly upper air data, and output from the RAP (Rapid Refresh model) which runs hourly. [Click here

Tornado Outbreaks Spawned by Tropical Cyclones at Landfall
The subject of tornadoes produced by landfalling tropical cyclones (tropical storms and hurricanes) has been a fascination (and a research interest) of mine for years. After working through several iterations of the research, the final manuscript was submitted an the A.M.S. journal. The A.M.S. journals, like most scientific publications, subject proposed articles to a formal peer review process. My manuscript has now been published in the April issue of Weather and Forecasting. Here is a link to the article. [Note: viewing requires Adobe Acrobat Reader.]

And perhaps you'd like to know how we're doing on rainfall and soil moisture conditions so far this year. Here's a clickable link to the Climate Prediction Center's latest map showing the Drought Severity Index (Palmer Long Term Index) for the U.S. By the way, if you're looking for that neat high-resolution visible satellite image which previously occupied this space, it's gone. But if you liked that shot, you can get them directly from NASA's Global Hydrology and Climate Center at the NASA MSFC, Huntsville, Alabama at this clickable link.
