Much Needed Rainfall from Edouard

Even though the center of circulation from tropical storm Edouard moved inland well to the east of where it was first forecast to make landfall, he still managed to produce some drought relieving rainfall across central and eastern sections of southeast Texas Tuesday. As a matter of fact, KIAH set a record for the date picking up 2.81'' which broke the old record of 2.65'' set back in 1994. A complete list of rainfall totals from around the region can be found below, along with the KHGX radar estimated storm total precip.

One item to note is that the Moody Tower H-Net site seems to be over estimating rainfall as it reported a little bit over 6'' from Edouard, while other official and non-official sites recorded rainfall in the 2-3 inch range. I archived the raw radar data files from KHGX for the entire event and will be going back over the data to see if it could have been a very small scale event; however I do not suspect that it was. Nicole and I will be running a calibration test on the gauge sometime over the next week or so and will post out findings. The other H-Net sites with the exception of UHCC (which we already know that is broken) gathered what looks to be very accurate rainfall data...matching up nicely with surrounding gauges and radar estimates.
