An all new edition of the ABC 33/40 Weather Xtreme video is available in the player below, and on iTunes…
Sure looks like showers and storms will be in our forecast for at least the next seven days as this blanket of very moist air is going nowhere. The 00Z sounding from the Shelby County Airport last night showed the precipitable water at a whopping 2.14″, which means any of the storms that form today will produce lots of rain. You can note on J.B.’s rain reports below some communities picked up between 2 and 3 inches of rain from the slow moving storms yesterday. And, rain is just what we need.
Some of the storms yesterday got out of hand, and most likely the same thing will happen today. There will be a chance of wet microbursts (small scale areas of straight line wind damage), and all of the storms will feature some amazing lightning output. Most of the storms will come from 12:00 until 10:00 p.m.
DITTO: That is pretty much the idea right on through Friday. A surface front will try to move down toward the Tennessee Valley at the end of the week, but most likely it will not have enough southward push to bring any drier air in here.
So, the Labor Day weekend will feature very warm and muggy days with intervals of sunshine and the chance of scattered showers and thunderstorms.
LONG RANGE: The GFS shows a very nice push of cool, Canadian air moving down into the U.S. in the September 7-9 time frame, but it keeps it north of the Deep South. Our time will come, but the model is beginning to latch onto the idea of holding it off until later in the month. We also note the GFS shows some kind of tropical system deep into voodoo country near Cuba on September 12.
WEATHER BRAINS: Don’t forget you can listen to our weekly 30 minute netcast anytime on the web, or on iTunes. This is the show all about weather hosted by David Black and featuring many familiar voices, including our meteorologists here at ABC 33/40. An all new episode is available; I actually hosted the show last night since David Black is out of town. You can listen right here on the blog; the player is on the top left. We look back on Hurricane Katrina; the show notes will be posted here a little later this morning.
