What an interesting day!

So on a day with a north-south oriented warm front, heavy rain, tornadoes, coastal flooding, 3 tropical systems spinning in the Atlantic, and Spanish class work & Methods class prep to do, I still managed to submit a travel proposal to NSF. We'll see how it gets reviewed (or if it even gets reviewed? - I've never submitted that kind of a proposal before).

Now on to the weather:

This morning awoke to find a 13F temperature increase in Annapolis overnight, from 65F yesterday to 78F today. This can be attributed to the passage of a warm front, which moved through us and promptly stalled about 40 km to our west. Seeing how the front axis has been the axis for very heavy rainfall today, I think we were fortunate to have the front move to our west. We've still received 2.72" of rain in the past 3 days at KNAK. It's interesting to compare that gauge total to the radar estimated storm total. The pixels of the KLIX radar are at least 1.5 km x 1.5 km out here at Annapolis (about 60 km from the radar), and the estimates for our area are quite varied. Two of the pixels divide right over my house (about 2 km from the gauge): one indicates 4.00" storm-total rainfall, the other 3.28". The KNAK station is even luckier, located at the intersection of 4 pixels! One is 2.64", another 3.04", a third 2.08", and the final one 2.48". Which one is right? They're all right overhead of the gauge (within a few hundred meters of it). That's quite a spread for one location - up to 0.96" difference. The gauge actually is on the high end of the estimates, again at 2.72" for the same period. Very interesting indeed!
