Big Story Weather – August 21, 2012

Afternoon Tropical Update for Aug 21, 2012: Now that we have Tropical Depression 9L on our hands and probably soon be looking at 10L this week. Let’s take a further look and see where these things are headed.
Currently we have Tropical Depression 9L which has formed as of this morning and has now put the United States on alert as this storm is going to intensify over the next few days. It looks like it will become our next hurricane of the season. In the left image we can see that there is also another area of Low pressure sitting just to the east of Mexico. This area has a medium chance of developing. However, it looks like it will be picked up by the stationary boundary and be absorbed into the front. The second feature is our TD#9, which is on a course to move westward around the Sub-Tropical High for the next few days as warnings have already been put in place for the Windward Islands. Expect the warnings to start expanding westward over the next couple of days. A third area is in the South-Central Atlantic and also needs to be watched for further development as it also has the possibility of strengthening into our next named system later this week. The image on the right is courtesy of F-5 Weather Data what we are looking at is one of our meteorological tools known as Spaghetti Models. They help us see all the models over-top of each other so that we can examine what the models are all looking at in one image. As you can see the initial runs of all the models are together with a 24-30hr straight westward movement, then after that caution needs to be used for future movement of the system. So if you are anywhere from Western Florida to South Carolina you need to stay alert to this system and pay attention to your local news agencies and also keep it here at redorbit.com as we will continue to provide you updates on this storm.
Big Story Weather from August 20: Yesterday we saw a few thunderstorms which produced hail in and around the Chicago area. Hail and strong winds also created damage into the panhandle of Texas. Isolated wind reports were found back into Arizona and over Florida along the frontal boundary. Hail sizes in Texas were around 1-1.75in in diameter. A few places in Arizona had winds reported in excess of 70mph and also eastward in Texas a few places peaked over 70mph for wind gusts.
Big Story Weather Outlook for August 21: Another nice day is in store for the Northeast as temps will hit the lower 80’s under partly cloudy skies. Look for some showers and thunderstorms to form along the frontal boundary in the Carolina’s. Otherwise partly cloudy skies will be found in the Baltimore area with high temps in the lower 80’s. The frontal boundary extends back into Florida bringing cloudy skies and scattered storms to the region for places like Orlando where the highs will be in the mid 80’s. High pressure will be in control of the weather back into the Plains with places like Saint Louis seeing high temps in the upper 70’s with partly cloudy skies. Another warm day is in store for the inner mountain west for places like Boise where high temps will soar into the lower to mid 90’s. A calm and mild day is in store for the West coast as partly cloudy skies will prevail for places like San Diego as high temps will be in the upper 70’s.
Big Story Weather International Outlook: High pressure over Japan will bring partly cloudy skies to the majority of the region for today. A frontal boundary extends from the Korea’s southward back into Eastern China bringing with it extensive cloudiness and periods of showers. The monsoonal trough will again bring showers and storms to Southeast Asia. Interaction between a frontal boundary over England and the remains of Gordon will impact Western Europe with showers and storms along with periods of gusty wind from Spain eastward into France. High pressure moving into Western South America will bring partly cloudy skies to the region, while a frontal boundary brings extensive cloudiness to the South Central part of Australia and look for High pressure to slowly start building in over Western Australia giving way to partly cloudy skies for the region.
