The table above covers the past eight days and shows the daily mean departure from normal of temperatures (d/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 eight days, adding those up, then dividing the sum by 8.

This table presents precipitation data at my home located 4.7 miles west of downtown Temple (also, 3 miles north of downtown Belton). I participate in CoCoRahs (learn more about the organization - click here) and my CoCoRahs identifier is TX-BEL-28. In 2014, I recorded 29.52 inches of precipitation. That's a little below normal. The first four months of 2014 (January through April) were exceptionally dry, with only 4.06 inches of precipitation. The next four months (May through August) were exceptionally wet, with 16.81 inches of rainfall. The final four months (September through December) were close to normal, at 8.72 inches.
(For the period January through April this year, I have measured 11.17 inches of precipitation, which is 0.58" above normal. (I am using the NWS normal precipitation records for Waco, the closest station for which I have "normal" data.)

 [& = 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 and 700mb from upper air soundings made around 00 UTC and 12UTC (7pm CDT and 7am CDT).  The table shows 12 stations near Central Texas that make these observations. The table will include not only today's data,but also the previous
five days. In the table above, PWAT is in inches and all temperature is 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 -05 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 .]

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.]

Computer Forecasts of Severe Storm Parameters

Have you ever wondered how computer models of the atmosphere can be used to forecast severe storms, check out this section in which I briefly explain some of the computer products and parameters used in forecasting severe storms.

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.
