Wow, was it hot yesterday or what? I wasn't hot since I was in the cool seat at the dunking booth at Kidfest in Old Town Helena. But unfortunately I'm a little croaky this morning, so please overlook the voice in the web video.
I thought we'd do something a bit different this morning, so I start out with a look at some weather around the world. The US is not the only place where weather can prove dangerous. Flooding from the monsoons have caused the death toll to lcimb to 62 in India. The monsoons began in mid-May and the death toll now stands at 432 for the season. In China, Typhoon Prapiroon - a name which means "God of rain" in Thai - was responsible for 57 deaths. The storm packed winds of 75 mph when it came ashore. And in the US, heavy rains have lead to flooding in New Mexico and extreme West Texas. El Paso which normally gets about 10 inches of rain a year has received 15 inches this year, most of the coming in the last week or so. El Paso has seen rain everyday since July 27th.
Tropics remain relatively quiet. The remnants of Chris were located just east of Havanna this morning. There is some possibility that Chris might regenerate when it reaches the warm water of the Gulf of Mexico, so we'll be keeping an eye on that area. Right now, though, there is very little convection associated with the remnants of Chris. Further east in the Atlantic, an area of disturbed weather was located about 550 miles southwest of the Cape Verde Islands. This area is showing some signs of organization and conditions seem favorable for slow development.
Back home the weather is just about the same. We saw a few more thunderstorms yesterday than I really thought we would see. I even got 0.03" of rain plus about two tons of thunder! Enough rain to settle the dust and that's about it. Storms persisted into the evening hours but most storms had died out by midnight.
After all those three-digit readings on Friday, none of the regular observing stations in Alabama got to 100. Most, though, did reach the upper 90s with a few of the climatological stations hitting 100 degrees.
The ridge aloft will build stronger today through Tuesday peaking in strength on Tuesday. After Tuesday the upper ridge retrogrades or moves west and it weakens. As that happens, a trough will develop along the east coast of the United States promising some relief to the Southeast US from the oppressive heat. We may even see a front approach the area on Friday though the timing may hedge more to Saturday. The GFS has remained pretty consistent in forecasting the trough, and past forecasts over the last several months have been pretty good with this pattern. So some relief may be forthcoming by next weekend.
The GFS MOS numbers for highs have been atrocious. This guidance does not do very well when we have relatively extreme events underway. MOS wants to work back toward climatology. But I did note that the GFS MOS was predicting a high of 88 next Sunday - now wouldn't that be nice?
I want to thank everyone for being patient as I migrated to the Mac for producing the web video. Took longer than I wanted it to, but I think I'm there now. Just give me an Internet connection and I can do map discussions from anywhere!
Stay cool and please take the heat seriously for a few more days. James Spann will be back in the saddle tomorrow morning with a fresh map discussion.
